  • tool for monitoring network traffic on Windows 7 Home

    - by Xah Lee
    for Windows 7 Home Edition: can anyone recommend a tool to monitor network traffic? either build-in or 3rd-party. I like to have a graph view (e.g. as in Task Manager) but also nice are tool that lets me see what IP/port that's incoming/outgoing. Command line is fine. Or even some tutorial. Thanks. (am old unix sys admin and web app dev. Though not much of a network admin and don't know much Windows. I need this tool just for my home PC, not in any pro capacity.)

  • USB transfer speed "logarithmically" decreases. Why and can it be improved?

    - by starship
    I have an external hard drive. Just today I tried to copy a bigger file (it was film of ~230 MB) and at first it rushed up until ~70%. There is started decreasing. At first it started at around 56 MB/s Then it rapidly dropped to 23 MB/s (File transfer was 70% complete) Then it slowly started decreasing until it was around 2 MB/s (File was ~90% complete) When it finished the transfer it was slightly above 1.5 MB/s. To describe it graphically: If you drew a curve of the decrease it would probably resemble the graph of a logarithm function So, what I'm really asking is: "Why does this happen?" and "Is there a way around it?" Thank you!

  • When to increase AWS RDS MySQL Server instance to larger CPU/RAM?

    - by rksprst
    I'm wondering at what stage do I need to increase the image for the RDS MySQL server to a larger CPU/RAM instance. The CPU utilization graph is near 0. The Avg Free Memory is around 150MB. The Avg Swap Usage is 420MB. Read Latency is 0-20ms/op it spikes up randomly. Avg write latency is on average 5ms/op but spikes up to 10-20ms/op. Are there some common rules here that I should follow? Thanks!

  • zabbix 2.2.1 no graphs in Web scenario

    - by Mick
    Hello for some time I have a problem with graphs in web scenarios on Zabbix 2.2.1, I put below the screen, this problem has appeared at every graph of web scenario This same scenario installed a second zabbixie that runs on my local virtual machine with zabbix. In my local machine all components of zabbix (server, frontend, agents), but in my production zabbix only zabbix frontend are separated from each other.

  • How can I speed up my Windows Server 2008 VPN Connection?

    - by Pure.Krome
    So I've installed VPN service that comes with Windows Server 2008. Works perfectly, etc. When a client remote desktops to one of the private servers at the office, via VPN .. it's pretty slow. Now - how long is a piece of string? So before I get all the obligatory checks, I'll list the things from Mr. Obvious: Our modem/router (fritz!box) has a data/graph that shows incoming and outbound bandwidth. Both directions are barely getting used when a client has RDP'd via VPN. Our office internet connection is running at 21,9 Mbit/s download 1,3 Mbit/s upload. I feel like it's maxing at .. modem speeds ?? Is there any tricks I can do to confirm this and possibly even fix this?

  • MySQL started to consume about 40% of system CPU time and got unresponsive suddenly

    - by Alex
    I use Debian 6.0.3 x86_64 and MySQL 5.5.20-1~dotdeb.0-log from the Dotdeb repository. MySQL process started to consume a lot of "sy" CPU time serveral hours ago according to this graph. I was not able to connect to running mysqld process and had to kill it. I found nothing useful in logs. My setup seems to be quite common (I assume Dotdeb just redistributes stock MySQL versions) and I have never seen anything like this before. What is the possible root cause of this? How can I prevent this situation in the future?

  • How to get average of multiple time series

    - by Supun Kamburugamuva
    I have few computers running. I want to get the average CPU usage of these computers and plot it as a graph. So I've collected CPU usage in regular intervals in these machines. So for each computer I have a data set of time and CPU usage. But the times at which CPU measurements are taken in different machines are not in sync. For example in 1st machine CPU may be measured in time 1, 5, 9. In the second machine CPU may be measured in time 2, 5, 8. I want to get an average data series from these different data sets. Could you point me to some resources? Thanks - Supun.

  • Fourier transform software

    - by CFP
    Hello everyone! After spending a lot of time searching for this, I thought that some SuperUser gurus might know the answer :) I'm searching for an open source application to compute an FFT, that could: * Import a list of points from a text file (in any format, I could write conversion scripts if needed), for example 0,1; 1,2; 4,5 * Compute the associated discrete transform, and output the list of coefficients Ideally, it would also display the plot and the associated fourier decomposition on the same graph, to allow comparison, but this is not absolutely needed. It can be either on Windows or on Linux/Unix. Can you think of a solution? Thanks, CFP.

  • Troubleshooting High Load on Plesk LAMP Dedicated Server

    - by Callmeed
    I have 2 nearly identical dedicated servers with the same provider. They also run a nearly identical software stack: RedHat 5 64-bit, Plesk, PHP, Apache, & MySQL. We use them for hosting custom sites we build. The problem is, while our 1st server has a load average (in top) of around 0.3, the 2nd server consistently has a load average of around 4.0 or higher. Basic functions in Plesk are delayed and there is a bit of latency when executing shell commands. Anyone have ideas why it would be so high? And why it would differ from our other server so much? Here is my current top output (sorted by %MEM) ... Any help is much appreciated ... top - 21:48:04 up 100 days, 4:28, 1 user, load average: 3.74, 4.20, 4.23 Tasks: 336 total, 1 running, 335 sleeping, 0 stopped, 0 zombie Cpu(s): 0.8%us, 0.4%sy, 0.0%ni, 91.3%id, 7.5%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 12290884k total, 11886452k used, 404432k free, 2920212k buffers Swap: 2096472k total, 244k used, 2096228k free, 6560692k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22536 apache 15 0 860m 547m 6484 S 0.0 4.6 0:10.96 httpd 26467 apache 15 0 859m 546m 6408 S 0.0 4.5 0:07.67 httpd 3620 apache 15 0 859m 545m 5552 S 0.0 4.5 0:06.15 httpd 1895 apache 15 0 858m 544m 6356 S 0.0 4.5 0:08.25 httpd 16933 apache 15 0 858m 544m 5488 S 0.0 4.5 0:01.57 httpd 6431 apache 15 0 856m 542m 6076 S 10.6 4.5 0:05.32 httpd 14417 apache 15 0 856m 542m 5568 S 0.0 4.5 0:03.88 httpd 15403 apache 15 0 855m 541m 5616 S 0.0 4.5 0:03.73 httpd 19165 apache 15 0 853m 539m 6252 S 0.0 4.5 0:12.40 httpd 15898 apache 15 0 852m 539m 5376 S 0.0 4.5 0:02.68 httpd 14401 apache 15 0 851m 538m 5460 S 0.0 4.5 0:02.97 httpd 15393 apache 15 0 851m 538m 5404 S 0.0 4.5 0:03.12 httpd 15427 apache 15 0 851m 538m 5496 S 0.0 4.5 0:02.44 httpd 14412 apache 15 0 851m 538m 5324 S 0.0 4.5 0:02.15 httpd 18330 apache 15 0 851m 537m 5136 S 0.0 4.5 0:01.30 httpd 18303 apache 15 0 848m 535m 5140 S 0.0 4.5 0:00.47 httpd 21190 apache 15 0 845m 533m 3988 S 0.0 4.4 0:00.33 httpd 15923 root 18 0 822m 521m 9928 S 0.0 4.3 10:04.81 httpd 22021 apache 15 0 828m 520m 4964 S 0.0 4.3 0:00.16 httpd 22146 apache 15 0 823m 515m 3016 S 0.0 4.3 0:00.02 httpd 22345 apache 15 0 822m 514m 2408 S 0.0 4.3 0:00.00 httpd 14721 apache 15 0 733m 510m 488 S 0.0 4.3 0:00.00 httpd 5094 root 15 0 1452m 122m 15m S 1.0 1.0 852:24.24 java 4636 mysql 15 0 532m 57m 6440 S 1.0 0.5 488:05.84 mysqld 4799 popuser 15 0 166m 53m 2368 S 0.0 0.4 0:36.64 spamd 16761 popuser 15 0 159m 46m 2312 S 0.0 0.4 0:00.38 spamd 4797 root 15 0 158m 45m 2448 S 0.0 0.4 0:01.27 spamd 5074 root 34 19 255m 20m 2144 S 0.0 0.2 1:37.53 yum-updatesd 9917 named 15 0 366m 9804 1980 S 0.0 0.1 0:10.26 named 4332 sso 18 0 119m 8028 5212 S 0.0 0.1 0:00.06 sw-engine-cgi 4341 sso 18 0 119m 8028 5212 S 0.0 0.1 0:00.07 sw-engine-cgi 4350 sso 18 0 119m 8028 5212 S 0.0 0.1 0:00.09 sw-engine-cgi 4352 sso 18 0 119m 8028 5212 S 0.0 0.1 0:00.11 sw-engine-cgi 4376 ntp 15 0 23388 5020 3896 S 0.0 0.0 0:00.58 ntpd 4331 sw-cp-se 15 0 61336 4572 1480 S 0.0 0.0 5:53.22 sw-cp-serverd 4213 haldaemo 15 0 31252 4460 1684 S 0.0 0.0 0:01.52 hald 4778 postgres 18 0 117m 4164 3484 S 0.0 0.0 0:00.11 postmaster 18555 root 16 0 98.3m 3716 2852 S 0.0 0.0 0:00.01 sshd 4488 sso 18 0 119m 3044 224 S 0.0 0.0 0:00.00 sw-engine-cgi 4489 sso 18 0 119m 3044 224 S 0.0 0.0 0:00.00 sw-engine-cgi 4492 sso 18 0 119m 3044 224 S 0.0 0.0 0:00.00 sw-engine-cgi 4493 sso 18 0 119m 3044 224 S 0.0 0.0 0:00.00 sw-engine-cgi 4490 sso 18 0 119m 3040 220 S 0.0 0.0 0:00.00 sw-engine-cgi

  • Nagios and rrd on a old server

    - by Pier
    I have an old server (P4 based) on which nagios (and all the other tools to monitor) is running. In the last few weeks we are seeing a strange behavior. In the /var/spool/pnp4nagios (where temporary files are stored before getting processed by pnp4nagios daemon) we have many files like perfdata.1274949941-PID-18839 and we get an error in npcd.log: [05-27-2010 11:17:46] NPCD: ThreadCounter 0/15 File is perfdata.1274951306-PID-27849 [05-27-2010 11:17:46] NPCD: File 'perfdata.1274951306-PID-27849' is an already in process PNP file. Leaving it untouched. Sometimes some graph are not drawn. The server is pretty loaded (around 5-6 normally) and i suspect that npcd goes in timeout and leave those files behind. What could I do (apart from change the server)? Few infos about the system: centos 5.5 nagios 3.2.1 pnp4nagios 0.6 (from sources) Thanks

  • Graphing services using pnp4nagios

    - by Matias
    Hi! I've managed to install pnp4nagios 0.6.3 and I'm a bit confused about how pnp4nagios generates graphics. Almost out of the box, it started graphs for ping and some http servers (not all of them). But, how can I make it graph things like disk utilization (When that value comes from SNMP)?? For example, ls /usr/local/pnp4nagios/var/perfdata/isis/ Cola_de_Mail.rrd Cola_de_Mail.xml HTTP.rrd HTTP.xml PING.rrd PING.xml Those are checks running on the host isis, but there are many other checks for that server that are not taken into account by pnp4nagios. How can I make pnp4nagios "see" the other checks?? Thanks!

  • Connecting tomcat6 to apache2

    - by StudentKen
    Disclaimier: Not a server admin I've been scratching my head over this for weeks now (not consistently mind you, as that would be maddening). I've been trying to connect my apache2 server to my tomcat server to the point where if someone encounters *.jsp or any servelet in navigating my web directory, it's handed over to tomcat. I have both Apache2.0 (port 9099) and Tomcat6 (9089) running on Debian lenny on the same box. Currently, mod_jk is enabled with mod_jk.conf in $apacheHOME/mods-enabled/ with content: # Where to find workers.properties JkWorkersFile /etc/apache2/workers.properties # Where to put jk shared memory JkShmFile /var/log/at_jk/mod_jk.shm # Where to put jk logs JkLogFile /var/log/at_jk/mod_jk.log # Set the jk log level [debug/error/info] JkLogLevel info # Select the timestamp log format JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " # Send servlet for context /examples to worker named worker1 JkMount /*/servlet/* worker1 # Send JSPs for context /examples to worker named worker1 JkMount /*.jsp worker1 my workers.properties located in $apacheHOME/ with content: workers.tomcat_home=/var/lib/tomcat6 workers.java_home=/usr/lib/jdk1.6.0_23/db/ worker.list=worker1 ps=/ worker.worker1.port=9071 worker.worker1.host=localhost worker.worker1.type=ajp13 my web.xml in $tomcatHOME/conf has the following servlets enabled <servlet> <servlet-name>default</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-cla$ <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>false</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>jsp</servlet-name> <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> <init-param> <param-name>fork</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>xpoweredBy</param-name> <param-value>false</param-value> </init-param> <load-on-startup>3</load-on-startup> </servlet> <servlet-mapping> <servlet-name>jsp</servlet-name> <url-pattern>*.jsp</url-pattern> </servlet-mapping> <session-config> <session-timeout>30</session-timeout> </session-config> From what I can tell, there's no funny buisness as both the apache2, tomcat, and mod_jk logs show green; yet whenever I navigate to a jsp, it simply displays the javascript. I'm unsure what the problem is exactly despite pouring over the logs and documentation for aid. I'm quite a greenhorn in the servelet world.

  • Good option for a transparent internet gateway on Mac OS X

    - by Gareth
    Hi I have a small network of Mac systems, and would like to add some internal monitoring of our internet usage, which has recently begun to climb. I would like to configure one of the machines as an internet gateway, and install some monitoring software that could provide graph indications of network usage by machine. The machine would then double as a workstation and as the internet gateway. I can manually configure the machines on the network to use it as a gateway, and would prefer to avoid an explicit http proxy (although it is an option if necessary). What software would serverfault users recommend to provide simple, easily configurable and maintainable network monitoring on Mac OS 10.5.7 (non-server)? The simplest requirement is monitor usage by IP Address, but additional tracking (e.g. destination, protocol, etc) would be useful.

  • What does the "Maximum Frequency" number mean in the Windows Resource Monitor?

    - by nhinkle
    In the Windows Resource Monitor's CPU tab, there is a status box and graph for the "Maximum Frequency", right next to the "CPU Usage" values. What does this mean? The value is sometimes over 100% on my system... what could that imply? By looking at CPU-z's real-time report of the processor's clock speed, it seems to be loosely related to what frequency the CPU is running at, which would imply that it means "percent of maximum possible frequency the CPU is running at"; this would be of relevance on systems with SpeedStep and/or TurboBoost technology (or similar). Furthermore, setting the system to "power saving mode" lowers the "maximum frequency" value to around 60%, while setting it to "high performance" mode sets it to around 110%. However, the percentage does not seem to exactly correlate to the CPU speed being shown. What value is this actually representing then?

  • why is mailgraph not updating ?

    - by jack
    I just installed mailgraph on a Linux Ubuntu 10.04 box monitoring Postifix. Everything seems to be working fine, but the graphs are not always updating. When I refresh the web page or close the browser and come back later, the graph updates and moves to the left, showing new time, the the data line is not drawn. Sometimes it does not update for several hours. I had started, stopped and restarted mailgraph-init and that doesn't seem to make a difference. Any ideas?

  • what's wrong with my Ubuntu 11.10 bind9 configuration?

  • RSync to WebDAV mounted volume very slow

    - by AlexC
    I have a mounted WebDAV store, which I am playing around with to try and put together my own pseudo-DropBox set up. However, it seems very slow to upload larger files (my bandwidth graph goes ok for a little bit, then just stops dead for long periods of time). Has anyone tried this? I'm wondering if the way it gets mounted makes rsync think it's a local drive or something and so may be chattier than it would be if it knew it was a mounted network drive? (I'm new to rsync so may be all wrong here!) I'm syncing using rsync -rv /source/directory/ /mounted/webdav/directory/ This is running using MacOS 10.6, and WebDAV is mounted using the native mounting mechanism.

  • Rendering composite/SVideo input with GraphEdit (comp./svid. source for crossbar)?

    - by Synetech
    Does anyone know how to form a GraphEdit graph to render composite/SVideo input (especially for a Hauppauge or AIW card)? Google (and Google Images) finds only results focusing on rendering the TV tuner which is already simple enough. The tv-tuner-in pins connect to the TvTuner/TvAudio source, but nothing seems to be able to connect to the Composite/SVideo pins. I have looked through the filters and could find no sources to connect to the Composite/SVideo input pins of the crossbar; GraphEdit always complains that they are not compatible.

  • Creating an office network and monitoring all activity without a proxy

    - by Robert
    We are setting up our office network and would like to track all the websites visited by our employees. However, we would not like to use any proxy based solutions. Our work is highly dependent on applications in which you cannot configure a proxy. Hence, the approach we would like to follow is setting up a router inside a computer (something like this : http://www.techrepublic.com/article/configure-windows-server-2003-to-act-as-a-router/5844624) This will also allow us to attach multiple ethernet cards and have redundancy in internet connectivity with complete abstraction from the user about which connection is being used. But most importantly, since all the traffic will be going through the computer (configured as a router) I assume there will be a way to run packet analysis on all the request / responses being made. For example, list all the FTP servers connected to (port 21), give a graph of all the URLs visited per day by frequency. Is there already a software which does this ? Or is it possible to build something like this ?

  • which server is best for me??

    - by mathew
    I am looking for a best hosting service for my website. My website is a PHP MySQl driven site which hase got site scrapping for more than 10 websites and near about 8-10 API pursing and some about 150 mb dat file reading(from local hard drive), and also one rss pursing,Live graph from other sites, geo map from Google,Map api from Google and so on. one widget which real-time result for any one who chose the same. so my question is which is best option for me. actually I am considering softlayer cloud as they are pretty cheap and more facilities than rackspace. another option is a dedicated server which has 2 single core processor, 4GB ram and 250GB sata II. with 100 mbps uplink. so please tell me which will be the best option?? I heard that dedicated server has lots of limitations than cloud. but for cloud they uses SAN for storage so I am afraid the reading proces for database may be bit slower...and their basic plan ram is only 1 GB.

  • Gnuplot with octave produces only entirely black bar diagrams

    My problem is the following: On my system (Linux Mint 14), the normal octave and gnuplot packages only produce completely black bar diagrams: I have tried to change the colours in any way I could imagine, but no avail: bar(xbin, yy, 'barwidth', 1, 'facecolor', 'r', 'edgecolor', 'b'); xlabel('x_i'); ylabel('p_i'); print -deps bars.eps However, when I plot the graph with the command graphics_toolkit fltk; It looks fine - but fltk doesn't either understand umlauts or LaTeX-style formula notation like p_i (necessary for captions and labels). Maybe I haven't configured something correctly. I just installed octave from the repos and thought it would work. Anyone can help?

  • How do I get a chart in LibreOffice Calc to have regular time intervals when the data is not regular?

    - by Dave M G
    I have an area chart in LibreOffice Calc where I would like the X axis to be measured in one month intervals spaced evenly apart. The data going into the graph, however, is not regularly spaced at one month. There can be zero, one, or two entries in any given month. Right now, the chart is keeping the horizontal pacing of the data consistent and adjusting the X axis to accomodate, which is the reverse of what I want. In the example picture below, you can see that there is one data point in March, one in May, and two in June. Along the X axis, April is gone and June is taking up double the space. Instead of this, I'd like the months to stay the same spacing so there is April, May, and June, and for the data area of the chart to compress or extend horiozontally as necessary. I have tried editing the X axis and adjusting the time intervals, but this doesn't seem to do anything. Is what I'm after possible?

  • Disable Offline Files (mobsync.exe) on Windows 7 Home

    - by Synetech
    This morning I was watching the CPU graph of a Windows 7 Home laptop and noticed that every few seconds, the CPU would spike several percent. I watched the processes and determined that it was mobsync.exe (Offline Files) that was the culprit. I tried the usual steps that Googling turns up, and clicking the Manage Offline Files link to bring up the Offline Files dialog to click Disable Synch does not work because the dialog will not display. This makes sense since everything I have read indicates that Offline Files is not even included/supported in the Home version, so I am at a loss as to why it is running at all, let alone why it is sucking up CPU cycles. (My best guess is that it was started when they pressed Win+X to access the Mobility Center.) Of course I can just kill mobsync, but it could always just come back. How/why would mobsync be running on a Home version and how can it be disabled (of course the Group Policy editor is not available on a Home version).

  • Munin - apache_watch_ plugin, does not show any data in the graphs that shows activity for per vhosts

    - by ovais.tariq
    I am using Munin for monitoring my server. I installed the apache_watch_ plugin so that i could see apache related activity. The graphs for apache_accesses, apache_processes and apache_volume work fine. But the graphs for Apache Documents served, Apache Input/output (bytes), Apache Requests don't show any activity in the graph. The important thing is that these graphs that don't show anything are supposed to show the data divided per vhosts. I am on Ubuntu 10.04.1 LTS (Lucid Lynx) and the munin version is 1.4.4. One thing that I think may be the cause for issue is that I have a separate config file for every vhost, which are included in the main config. But I can't really figure out any solution. Any help will be greatly appreciated!

  • Why is IIS 7.5 flushing file cache very often?

    - by Steffen
    We're running a Win 2008 R2 server with IIS 7.5 for serving image files. It's only used for static content, and file caching has been set up to cache files for 10 minutes. However the IIS frequently completely flushes the cache (seen by using Perfmon) It's not application pool recycling, it's not because the TTL has expired, so now I'm at a loss :-( I've included a screenshot of the perfmon graph where you can clearly see the issue. Is there anywhere I can see WHY it's doing these flushes ? (Note: I'm aware I could maybe detect it by attaching a debugger to the process, but that's not an option because it's a production server, and it cannot handle the slowdown a debugger would cause)
