  • JavaCard monitoring folder

    - by GxG
    I want to write a two way application: applet for javacard and an application in C#. I've got the C# covered but i want to know if with JavaCard i can monitor a folder on the memory and how would i go about doing that. I have a shared folder let's call it temp in which i want to store buffer information between the simulated smartcard and the C# application. The C# application will only read from that folder and display the information, but also it will write requests towards the smartcard. For example i simulate entering the PIN for the card. The applet will write a file containing available options and the C# application will read that file and display those options; from the C# app i will chose and option and write a request file in the same folder. This is when the smartcard which is monitoring that folder will read the request and issue a response. Can i make the smartcard monitor that folder? I was thinking of using encrypted XML files for the request/response operations. But simple .txt files are good to. I am limited to using JavaCard v2.2.1, and every operation has to be encrypted/decrypted. (with the ciphering i have no problem)

  • OS Analytics with Oracle Enterprise Manager (by Eran Steiner)

    - by Zeynep Koch
    Oracle Enterprise Manager Ops Center provides a feature called "OS Analytics". This feature allows you to get a better understanding of how the Operating System is being utilized. You can research the historical usage as well as real time data. This post will show how you can benefit from OS Analytics and how it works behind the scenes. The recording of our call to discuss this blog is available here: https://oracleconferencing.webex.com/oracleconferencing/ldr.php?AT=pb&SP=MC&rID=71517797&rKey=4ec9d4a3508564b3Download the presentation here See also: Blog about Alert Monitoring and Problem Notification Blog about Using Operational Profiles to Install Packages and other content Here is quick summary of what you can do with OS Analytics in Ops Center: View historical charts and real time value of CPU, memory, network and disk utilization Find the top CPU and Memory processes in real time or at a certain historical day Determine proper monitoring thresholds based on historical data Drill down into a process details Where to start To start with OS Analytics, choose the OS asset in the tree and click the Analytics tab. You can see the CPU utilization, Memory utilization and Network utilization, along with the current real time top 5 processes in each category (click the image to see a larger version):  In the above screen, you can click each of the top 5 processes to see a more detailed view of that process. Here is an example of one of the processes: One of the cool things is that you can see the process tree for this process along with some port binding and open file descriptors. Next, click the "Processes" tab to see real time information of all the processes on the machine: An interesting column is the "Target" column. If you configured Ops Center to work with Enterprise Manager Cloud Control, then the two products will talk to each other and Ops Center will display the correlated target from Cloud Control in this table. If you are only using Ops Center - this column will remain empty. The "Threshold" tab is particularly helpful - you can view historical trends of different monitored values and based on the graph - determine what the monitoring values should be: You can ask Ops Center to suggest monitoring levels based on the historical values or you can set your own. The different colors in the graph represent the current set levels: Red for critical, Yellow for warning and Blue for Information, allowing you to quickly see how they're positioned against real data. It's important to note that when looking at longer periods, Ops Center smooths out the data and uses averages. So when looking at values such as CPU Usage, try shorter time frames which are more detailed, such as one hour or one day. Applying new monitoring values When first applying new values to monitored attributes - a popup will come up asking if it's OK to get you out of the current Monitoring Policy. This is OK if you want to either have custom monitoring for a specific machine, or if you want to use this current machine as a "Gold image" and extract a Monitoring Policy from it. You can later apply the new Monitoring Policy to other machines and also set it as a default Monitoring Profile. Once you're done with applying the different monitoring values, you can review and change them in the "Monitoring" tab. You can also click the "Extract a Monitoring Policy" in the actions pane on the right to save all the new values to a new Monitoring Policy, which can then be found under "Plan Management" -> "Monitoring Policies". Visiting the past Under the "History" tab you can "go back in time". This is very helpful when you know that a machine was busy a few hours ago (perhaps in the middle of the night?), but you were not around to take a look at it in real time. Here's a view into yesterday's data on one of the machines: You can see an interesting CPU spike happening at around 3:30 am along with some memory use. In the bottom table you can see the top 5 CPU and Memory consumers at the requested time. Very quickly you can see that this spike is related to the Solaris 11 IPS repository synchronization process using the "pkgrecv" command. The "time machine" doesn't stop here - you can also view historical data to determine which of the zones was the busiest at a given time: Under the hood The data collected is stored on each of the agents under /var/opt/sun/xvm/analytics/historical/ An "os.zip" file exists for the main OS. Inside you will find many small text files, named after the Epoch time stamp in which they were taken If you have any zones, there will be a file called "guests.zip" containing the same small files for all the zones, as well as a folder with the name of the zone along with "os.zip" in it If this is the Enterprise Controller or the Proxy Controller, you will have folders called "proxy" and "sat" in which you will find the "os.zip" for that controller The actual script collecting the data can be viewed for debugging purposes as well: On Linux, the location is: /opt/sun/xvmoc/private/os_analytics/collect If you would like to redirect all the standard error into a file for debugging, touch the following file and the output will go into it: # touch /tmp/.collect.stderr   The temporary data is collected under /var/opt/sun/xvm/analytics/.collectdb until it is zipped. If you would like to review the properties for the Analytics, you can view those per each agent in /opt/sun/n1gc/lib/XVM.properties. Find the section "Analytics configurable properties for OS and VSC" to view the Analytics specific values. I hope you find this helpful! Please post questions in the comments below. Eran Steiner

  • unexplainable packet drops with 5 ethernet NICs and low traffic on Ubuntu

    - by jon
    I'm stuck on problem where my machine started to drops packets with no sign of ANY system load or high interrupt usage after an upgrade to Ubuntu 12.04. My server is a network monitoring sensor, running Ubuntu LTS 12.04, it passively collects packets from 5 interfaces doing network intrusion type stuff. Before the upgrade I managed to collect 200+GB of packets a day while writing them to disk with around 0% packet loss depending on the day with the help of CPU affinity and NIC IRQ to CPU bindings. Now I lose a great deal of packets with none of my applications running and at very low PPS rate which a modern workstation NIC would have no trouble with. Specs: x64 Xeon 4 cores 3.2 Ghz 16 GB RAM NICs: 5 Intel Pro NICs using the e1000 driver (NAPI). [1] eth0 and eth1 are integrated NICs (in the motherboard) There are 2 other PCI-X network cards, each with 2 Ethernet ports. 3 of the interfaces are running at Gigabit Ethernet, the others are not because they're attached to hubs. Specs: [2] http://support.dell.com/support/edocs/systems/pe2850/en/ug/t1390aa.htm uptime 17:36:00 up 1:43, 2 users, load average: 0.00, 0.01, 0.05 # uname -a Linux nms 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I also have the CPU governor set to performance mode and irqbalance off. The problem still occurs with them on. # lspci -t -vv -[0000:00]-+-00.0 Intel Corporation E7520 Memory Controller Hub +-02.0-[01-03]--+-00.0-[02]----0e.0 Dell PowerEdge Expandable RAID controller 4 | \-00.2-[03]-- +-04.0-[04]-- +-05.0-[05-07]--+-00.0-[06]----07.0 Intel Corporation 82541GI Gigabit Ethernet Controller | \-00.2-[07]----08.0 Intel Corporation 82541GI Gigabit Ethernet Controller +-06.0-[08-0a]--+-00.0-[09]--+-04.0 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | | \-04.1 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | \-00.2-[0a]--+-02.0 Digium, Inc.

On the old system, if it couldn't keep up this is where the drops would be. I drop packets on multiple interfaces just about every second, usually in small increments of 2-4. I tried all these sysctl values, I'm currently using the uncommented ones. # cat /etc/sysctl.conf # high net.core.netdev_max_backlog = 3000000 net.core.rmem_max = 16000000 net.core.rmem_default = 8000000 # defaults #net.core.netdev_max_backlog = 1000 #net.core.rmem_max = 131071 #net.core.rmem_default = 163480 # moderate #net.core.netdev_max_backlog = 10000 #net.core.rmem_max = 33554432 #net.core.rmem_default = 33554432 Here's an example of an interface stats report with ethtool.

With and without, it's the same. This is what my interrupt stats looked like before the upgrade, after, with ACPI on PCI it showed multiple NICs bound to an interrupt and shared with other devices such as USB drives which I didn't like so I think i'm going to keep it with ACPI off as it's easier to designate sole purpose interrupts. Is there any advantage I would have using the default i.e. ACPI w/ PCI. ? # cat /etc/default/grub | grep CMD_LINE GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 noacpi pci=noacpi" GRUB_CMDLINE_LINUX="" # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 45 0 0 16 IO-APIC-edge timer 1: 1 0 0 7936 IO-APIC-edge i8042 2: 0 0 0 0 XT-PIC-XT-PIC cascade 6: 0 0 0 3 IO-APIC-edge floppy 8: 0 0 0 1 IO-APIC-edge rtc0 9: 0 0 0 0 IO-APIC-edge acpi 12: 0 0 0 1809 IO-APIC-edge i8042 14: 1 0 0 4498 IO-APIC-edge ata_piix 15: 0 0 0 0 IO-APIC-edge ata_piix 16: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb2 18: 0 0 0 1350 IO-APIC-fasteoi uhci_hcd:usb4, radeon 19: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb3 23: 0 0 0 4099 IO-APIC-fasteoi ehci_hcd:usb1 38: 0 0 0 61963 IO-APIC-fasteoi megaraid 48: 0 0 1002319 4 IO-APIC-fasteoi eth0 49: 0 0 38772 3 IO-APIC-fasteoi eth1 77: 0 0 130076 432159 IO-APIC-fasteoi eth4 78: 0 0 0 23917 IO-APIC-fasteoi eth5 82: 1329033 0 0 4 IO-APIC-fasteoi eth2 83: 0 4886525 0 6 IO-APIC-fasteoi eth3 NMI: 5 6 4 5 Non-maskable interrupts LOC: 61409 57076 64257 114764 Local timer interrupts SPU: 0 0 0 0 Spurious interrupts IWI: 0 0 0 0 IRQ work interrupts RES: 17956 25333 13436 14789 Rescheduling interrupts CAL: 22436 607 539 478 Function call interrupts TLB: 1525 1458 4600 4151 TLB shootdowns TRM: 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 Machine check exceptions MCP: 16 16 16 16 Machine check polls ERR: 0 MIS: 0 Here's sample output of vmstat, showing the system.

I can't figure out why my PCI-X slots are negotiated as PCI. The network cards are all PCI-X with the exception of the integrated NICs that came with the server. In the output below it looks as if eth3 and eth2 negotiated at PCI-X speeds rather than PCI:66Mhz. Wouldn't they all drop to PCI:66Mhz? If your integrated NICs are PCI, as labeled below (eth0,eth1), then wouldn't all devices on your bus speed drop down to that slower bus speed? If not, I still don't know why only one of my NICs ( each has two ethernet ports) is labeled as PCI-X in the output below.

  • What are some techniques to monitor multiple instances of a piece of software?

    - by Geo Ego
    I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status directly. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

  • Unable to use JConsole with Tomcat running as windows service

    - by Kees de Kooter
    I am running tomcat 6.0.18 as a windows service. In the service applet the jvm is configured default, i.e. it is using jvm.dll of the JRE. I am trying to monitor this application with JConsole but cannot connect to it locally. I added the parameter -Dcom.sun.management.jmxremote (which works when starting tomcat with the start.bat script). But the jvm does not seem to pick up the parameter.

  • How to Sum calulated fields

    - by Nazero Jerry
    I‘d like to ask I question that here that I think would be easy to some people. Ok I have query that return records of two related tables. (One to many) In this query I have about 3 to 4 calculated fields that are based on the fields from the 2 tables. Now I want to have a group by clause for names and sum clause to sum the calculated fields but it ends up in error message saying: “You tried to execute a query that is not part of aggregate function” So I decided to just run the query without the totals *(ie no group by , sum etc,,,) : And then I created another query that totals my previous query. ( i.e. using group by clause for names and sum for calculated fields… no calculation here) This is fine ( I use to do this) but I don’t like having two queries just to get summary total. Is their any other way of doing this in the design view and create only one query?. I would very much appreciate. Thankyou: JM

  • Mbean registered but not found in mbean Server

    - by Prisco
    I have a problem about the mbeans. I have created a simple mbean and I have registered it on the default mBeanServer that is run (Via eclipse or java -jar mbean.jar) and in the same process if I try to fouund the mbean registered with a simple query: for (ObjectInstance instance : mbs.queryMBeans(ObjectNameMbean, null)) { System.out.println(instance.toString()); } the query retuerns my mbean, but if I start another process and try to search this mbean registered the mbeas is not found! why? The approch is : (Process that is running) public static void main(String[] args) throws Exception { MBeanServer mbeanServer =ManagementFactory.getPlatformMBeanServer(); ObjectName objectName = new ObjectName(ObjectNameMbean); Simple simple = new Simple (1, 0); mbeanServer.registerMBean(simple, objectName); while (true) { wait (Is this necessary?) } } So this is the first process that is running (that has the only pourpose to registry the mbean, because there is another process that want to read these informations. So I start another process to search this mbean but nothing. I 'm not using jboss but the local Java virtual Machine but my scope is to deploy this simple application in one ejb (autostart) and another ejb will read all informations. All suggestions are really apprecciated. This example should be more useful : Object Hello: public class Hello implements HelloMBean { public void sayHello() { System.out.println("hello, world"); } public int add(int x, int y) { return x + y; } public String getName() { return this.name; } public int getCacheSize() { return this.cacheSize; } public synchronized void setCacheSize(int size) { this.cacheSize = size; System.out.println("Cache size now " + this.cacheSize); } private final String name = "Reginald"; private int cacheSize = DEFAULT_CACHE_SIZE; private static final int DEFAULT_CACHE_SIZE = 200; } Interface HelloBean (implemented by Hello) public interface HelloMBean { public void sayHello(); public int add(int x, int y); public String getName(); public int getCacheSize(); public void setCacheSize(int size); } Simple Main import java.lang.management.ManagementFactory; import java.util.logging.Logger; import javax.management.MBeanServer; import javax.management.ObjectName; public class Main { static Logger aLog = Logger.getLogger("MBeanTest"); public static void main(String[] args) { try{ MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); ObjectName name = new ObjectName("ApplicationDomain:type=Hello"); Hello mbean = new Hello(); mbs.registerMBean(mbean, name); // System.out.println(mbs.getAttribute(name, "Name")); aLog.info("Waiting forever..."); Thread.sleep(Long.MAX_VALUE); } catch(Exception x){ x.printStackTrace(); aLog.info("exception"); } } } So now I have exported this project as jar file and run it as "java -jar helloBean.jar" and by eclipse I have modified the main class to read informations of this read (Example "Name" attribute) by using the same objectname used to registry it . Main to read : public static void main(String[] args) { try{ MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); ObjectName name = new ObjectName("ApplicationDomain:type=Hello"); System.out.println(mbs.getAttribute(name, "Name")); } catch(Exception x){ x.printStackTrace(); aLog.info("exception"); } } But nothing, the bean is not found.

    We have successfully migrated all of our PHP and Ruby apps to use New Relic RPM both for Application performance measurements and server monitoring. We are very please with results, which have enabled us to improve the overall performance of the platfrom numeral times. We still have a lot of Perl applications which we need to support for legacy purposes, but in comparison to our New Relic powred apps we are completely blind to whats happening inside the apps and in peak hours.

  • SCOM 2012 DNS Forwarder Availability Monitor

    - by Massimo
    Background: I have an environment with two different AD domains, each in its own forest, each with two Windows Server 2008 R2 domain controllers acting as DNS servers. There is no trust between the domains. Each DNS server manages the main DNS zone for its AD domain, and then some other zones, including the reverse lookup zone for its IP subnets; all zones are AD-integrated; all DNS servers which manages a zone are correctly listed as authoritative name servers for that zone. So, the situation is like this (using fake names and IP addresses): Domain A: DNS domain: a.dom IP subnet: 192.168.1.X DC/DNS Servers: serverA1.a.dom (192.168.1.1) and serverA2.a.dom (192.168.1.2) Authoritative zones: a.dom, 1.168.192.in-addr.arpa, somezone.local Domain B: DNS domain: b.dom IP subnet: 10.0.0.X DC/DNS Servers: serverB1.b.dom (10.0.0.1) and serverB2.b.dom (10.0.0.2) Authoritative zones: b.dom, 0.0.10.in-addr.arpa, someotherzone.local DNS servers in domain A have conditional forwarders defined for each zone managed by DNS servers in domain B, forwarding to both domain B's DNS servers; DNS servers in domain B have the opposite configuration. All forwarders are stored in Active Directory. All is working perfectly, and computers in each domain can resolve forward and reverse DNS queries for both domains, using their domain's DNS servers. The problem: I have SCOM 2012 deployed in domain A, with the SCOM agent installed on both DCs; the management packs for Active Directory and DNS Server are installed and up-to-date. I have a series of alerts like the following ones on both domain controllers; each alert is generated for each forwarded zone and for each forwarded server: Forwarder someotherzone.local (10.0.0.1) cannot resolve the host name 192.168.1.1,someotherzone.local for serverA1.a.dom Forwarder someotherzone.local (10.0.0.2) cannot resolve the host name 192.168.1.1,someotherzone.local for serverA1.a.dom Forwarder someotherzone.local (10.0.0.1) cannot resolve the host name 192.168.1.2,someotherzone.local for serverA2.a.dom Forwarder someotherzone.local (10.0.0.2) cannot resolve the host name 192.168.1.2,someotherzone.local for serverA2.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.1) cannot resolve the host name 192.168.1.1,0.0.10.in-addr.arpa for serverA1.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.2) cannot resolve the host name 192.168.1.1,0.0.10.in-addr.arpa for serverA1.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.1) cannot resolve the host name 192.168.1.2,0.0.10.in-addr.arpa for serverA2.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.2) cannot resolve the host name 192.168.1.2,0.0.10.in-addr.arpa for serverA2.a.dom The only exception is the main AD DNS zone managed by domain B's DNS servers (b.dom): for that conditional forwarder, no alert is generated and the forwarder availability monitor is green. Ok, what does this mean? What are those monitors trying to tell me? What are they checking? What's actually wrong? And why there is no error for the "b.dom" zone, which is configured in the exact same way as the other ones, both as a zone in domain B's DNS servers and as a forwarder in domain A's DNS servers?

  • Configure Zabbix to send email notifications through Exim

    - by gshankar
    I've been working through the installation and configuration of Zabbix over the past couple of days and I think I've finally got everything working... except the sending of notifications / alerts. I'm running on a Ubuntu server which is using Exim to send emails. I'd previously used this Exim setup to send notifications for Nagios so I know that Exim itself works. However, I can't seem to get Zabbix to send out notifications. Here's what I've done so far: Set up a "test trigger" like so: Trigger severity >= "Information" Send message to User "Admin" The Admin user has a email contact (and I've sent command line emails from Exim on the server using "sendmail" to this email address successfully) The media type for email is set. (I've tried 127.0.0.1) I've checked the user permissions and it is read/write for all host groups The triggers are definitely getting set but no actions are being called... I think my problem is within Zabbix as it's not actually executing the actions And idea how to configure this correctly?

  • DB2 insert performance - How to measure

    - by svrist
    [From stackoverflow] Im trying to find a way to speedup my inserts to a DB2 9.7.1 (ubuntu linux) Im watching vmstat and trying to gather some statistics via the db2 get snapshot commands but im not able to figure out which numbers im looking for to be able to see where the trouble is. I've read lits of stuff like http://www.eggheadcafe.com/software/aspnet/35692526/question-multiple-row-in.aspx, and http://www.ibm.com/developerworks/data/library/tips/dm-0403wilkins/ and tricks like ALTER TABLE lalala APPEND ON works somewhat (the difference between a dd if=/dev/zero and insert is still a factor 10) but I would like to be able to find the counters or other performance indicators that actually show why it makes sense to use those tricks. For example: What is the metric called that shows me that it is buffer pages allocation (FSCR stuff) that is the problem Where do I see that the insert time is hampered by clustered indexes? I find db2top very useful but im still searching for more direct view of "this is your bottleneck" methods

  • How to find virtualization performance bottlenecks?

    - by Martin
    We have recently started moving our C++ build server(s) from real machines into VMs. (MS Hyper-V) We have some performance issues that I've currently no idea how to address. We have: Test-Box - this is a piece of desktop workstation hardware my co-worker used to set up the VM before we moved it to the actual server hardware Srv-Box - this is the server hardware Test-Box-Real - This is Windows running directly on the Test-Box HW Test-Box-VM - This is Windows in a Hyper-V VM on the Test-Box HW Srv-Box-Real- This is Server2008R2 running on the Srv-Box HW. Srv-Box-VM- This is Windows running in a Hyper-V VM on the Srv-Box HW, i.e. on Srv-Box-Real. Now, the problem is that we compared Build times between Test-Box-Real and Test-Box-VM and they were basically equal (within about 2%). Then we moved the VM to the Srv-Box machine and what we saw there is that we have a significant performance degradation between Srv-Box-Real and Srv-Box-VM, that is, where we saw no differences on the Test HW we now do see major differences in performance on the actual Server HW. (Builds about ~~ 50% slower inside the VM.) I should add that both the Test-Box and the Srv-Box are only running this one single VM and doing nothing else. I should also note that the "Real" OS is Win2008R2(64bit) and the VM hosted OS is Wind2003R2(32bit). Hardware specs: Srv-Box: Intel XEON E5640 @ 2.67Ghz (This means 8 cores with hyperthreading on the Real system and "only" 4 cores on the VM, since Hyper-V doesn't allow for hyperthreading, but number of cores doesn't seem to explain the problem here.) 16GB RAM (we have 4GB assigned to the VM) Virtual DELL RAID 1 (2x 450GB HUS156045VLS600 Hitachi 15k SAS drives) Test-Box: Intel XEON E31245 @ 3.3GHz 16GB RAM WD VelociRaptor 600GB 10k RPM SATA Note again that I'm only concerned with the differences between Srv-Box-Real and Srv-Box-VM (high) vs. the differences seen btw. Test-Box-Real and Test-Box-VM (low). Why would one machine have parity when comparing VM vs Real performance and the other (server grade HW no less) would have a large disparity? (Both being XEON CPUs ...)
