• Utility to continuously monitor an arbitrary command

  - by Tomas

  I seem to recall there exists a small UNIX tool to repeatedly execute and display the output of another command at a given interval. Kind of like "top" works by default but then for any other command. Does anybody know such utility?

• Complete stack traces from Hyperic

  - by Mike Kushner

  I've setup Hyperic to run on our CI-machine, and every once in a while it reacts to some random stack trace and sends of an alert. So far so good, we've caught a lot of intermittent bugs that way. My only issue is that the alert only contains the first error line and not the entire stack trace, which requires me to access the machine and look at the logs manually. Is there any way to modify the alert message to contain more information, alternatively to include the log file in the alert mail?

• Which network performance management software do you use?

  - by Jamie Keeling

  Hello, I am looking at the various options available for network performance management software, some of the solutions I've found so far are: Proprietary: HP - ProCurve Universal: SolarWinds - Orion Open Source: OpenNMS I am trying to discover the benefits of each package over the other and reasons as to why you would go for one (Such as size of the network, overall cost etc..). I'm curious as to which ones other people use and why? Each customer has their own needs and requirements and it would be great to hear some of yours. Thank you for your time.

• Is there a program to show programs loading during the boot process in real time?

  - by Gary M. Mugford

  Hi all, There are any number of programs that will show me WHAT will run during the boot process for Windows XP. I've always been partial to Mike Lin's version but there are several others, some of which are quite possibly superior. That's not the issue. What I'd really like is a program that would load first and then would list the programs that were about to load and then check them off as the programs loaded. This isn't something I necessarily need for myself. But certain family members get click happy as soon as they see the icon they eventually want to run and end up clicking on it. THIRTY TWO TIMES in one memorable crash-inducing spasm. If there was some way for 'progress' to be shown during the loading of from the various spots Windows auto-loads from, PLUS a BIG BANNER saying "Please do not move the mouse or click on anything until done.", I think I might cut down on my early morning family support calls significantly. I've tried a variety of searches, but I couldn't find the ones that show in real time in the forest of links to programs that will show the list after the fact. Any leads? If not, do any of you who write the after-the-fact listers want to take a shot at producing a utility to do what I think would be a relatively popular utility? Best of the season to all of you and yours. Thanks in advance for any replies, GM

• Reformat a WindowsXP drive: Quick, regular, or leave the current file-system

  - by Julie

  When reformatting, Windows XP ask me to choose from these formatting methods. (Implying that ALL of them are "formatting methods"... even #3) Reformat using NTFS (quick) Reformat using NTFS Leave the current file-system intact (no changes) What choice #3 really mean? Does it mean: A. Leave the current file-system (whatever file-system is already in use) and reformat to match that. (ie. If you current have NTFS, reformat to that again. If you currently have FAT32, reformat to that again. That is: Reformat without changing to a different file-system. Leave the current type.) or... B. Do absolutely nothing. Don't format. Don't delete any of my files. Abort the formatting process entirely.

• Hyperic HQ says the server is down, but it is not!

  - by Diego Jancic

  Hi, I've been using HQ for a couple months now, and everything worked fine. But since yesterday all resources go down for a couple hours, and then everything restores to normal, and then go down again without doing anything. The server of course is working, the HQ server and agent are both working, and the IPs were not modified. I've tried to re-run the setup in the HQ agent, and it did not change anything. Agent is in Windows 2008, and Server is in Windows 2003. I'm using HQ Version 4.1.2 (build #1053 - May 06, 2009 - Release Build) Any hint? Thanks! Update: I guess (although I'm not sure) it stopped working when the disk on the server went full, with 0 bytes of free space. Of course I've freed more than 15gbs and restarted the HQ server/database.

• How to monitor passenger with monit

  I want to set up monit to monitor passenger but everything I've found so far has basically said just monitor your website using monit. If possible I'd like to monitor passenger directly so I have more control over it.

  - by Errol Gongson

  I am installing postfix and I am confused what to put for the system mail name. It has an exmaple that sais use "example.org" if a mail address on the system is "[email protected]" but it also sais that the mail name should be the FQDN. my hostname is "mercury" and my FQDN is "mercury.pacificseatheat.org", so should I use "pacificseatheat.org" or "mercury.pacificseatheat.org" for the system mail name? Thanks

• How can ASP.NET's "Request Wait Time" be 0 when "Requests Queued" is consistently in the hundreds?

  - by ondrej

  I'm curious why Performance Monitor claims I always have a few hundred ASP.NET 3.5 requests "queued". The "Requests Queued" "ASP.NET v2.0.50727" performance counter is hovering in the few-hundred range despite the fact "Request Wait Time" is consistently 0. If each and every request never waits even a fraction of a millisecond, how could it be in the queue? The "ASP.NET Apps v2.0.50727" counters for "Requests In Application Queue" and "Request Wait Time" are always 0.

• How to check for bottlenecks in Windows Server 2008 R2

  - by Phil Koury

  I recently switched out a 10 year old server for a brand new server in a small office and upgraded from Windows Server 2000 to Windows Server 2008 R2. After the switch was complete and some configurations were changed around we are running into what appear to be some bottlenecks in the network speed. Accessing programs on the server is slower (resulting in long loading times, slower report generation, etc.) than it was on the old server hardware. I am wondering what options or tools I have, if there are any at all, to find out exactly where these hang ups might be coming from.

• Monit can't detect MySQL, but I can

  - by Matchu

  Monit is configured to watch MySQL on localhost at port 3306. check process mysqld with pidfile /var/lib/mysql/li175-241.pid start program = "/etc/init.d/mysql start" stop program = "/etc/init.d/mysql stop" if failed port 3306 protocol mysql then restart if 5 restarts within 5 cycles then timeout My application, which is configured to connect to MySQL via localhost:3306, is running just fine and can access the database. I can even use MySQL Query Browser to connect to the database remotely via port 3306. The port is totally open and possible to connect to. Therefore, I'm pretty darn certain that it's running. However, running monit -v reveals that Monit cannot detect MySQL on that port. 'mysqld' failed, cannot open a connection to INET[localhost:3306] via TCP This happens consistently, until Monit decides not to track MySQL anymore, as configured. How can I begin to troubleshoot this issue?

• How reliable is HDD SMART data?

  - by andahlst

  Based on SMART data, you can judge the health of a disk, at least that is the idea. If I, for instance, run sudo smartctl -H /dev/sda on my ArchLinux laptop, it says that the hard drive passed the self tests and that it should be "healthy" based on this. My question is how reliable this information is, or more specifically: If according to the SMART data this disk is healthy, what are the odds of the disk suddenly failing despite this? This assumes the failure is not due to some catastrophic event that impossibly could have been predicted, such as the laptop falling down on the floor causing the drive heads to hit the disk. If the SMART data does not say the disk is in good shape, what are the odds of the disk failing within some amount of time? Is it possible that there will be false positives and how common are these? Of course, I keep backups no matter what. I am mostly curious.

• Monitor network traffic on a per-app basis in OS X?

  - by dougoftheabaci

  Title says it all. I'm looking for an app for OS X that will tell me what applications are using the network and what their in/out is. I can get most of the way there with LittleSnitch but it's the bandwidth part that it fails at. The only app I've come across that comes close is "Rubbernet" and while it does look like it would probably do what I want, it's very expensive (more than LittleSnitch) and doesn't look like it gets regular feature updates. Any recommendations?

• Screen flicker -> Severe System Slowdown?

  - by Adam Robinson

  I'm using a Dell D830 laptop, and over the last few weeks it's been developing a very irritating screen flicker problem that leads to the system slowing down almost to the point of unusability. At seemingly random times (no commonality between how long the system has been running, what I was doing, what applications were open, etc.) my screen (I use two external LCD's with the laptop closed in a dock) flickers for a moment, then the system becomes incredibly slow. The screen redraws painfully slowly--almost like what you might expect to see with generic graphics drivers installed--and the entire system is maddeningly unresponsive. The only thing that seems to be able to correct the issue is a restart. I've checked the event logs and nothing out of the ordinary is there, and definitely nothing that's common to all of the events. I'm running XP Pro SP2. Any ideas?

• Ubuntu: Take actions when system temperature gets too high

  - by Josh

  One of the CPU fans on my Compaq Presario laptop running Ubuntu 9.10 seems to have bit the dust. The fan is deep within the case and I intend to replace the laptop in the next 6 months so it's not worth replacing it. I have the laptop on a cooling pad and most of the time the system is fine, CPU temps around 90°-110°F. Occasionally, however, I'm seeing random lockups which I believe is due to the system overheating. How can I configure the system to: Lower the CPU speed when the temperature reaches a certain level? (I.E. 110°F) Shutdown the system when the tempature reaches a critical level? (And what would that be? 130°?)

• Can't get any SMART or temperature data from HDDs

  - by Regs

  I have a PC with recently installed Gigabyte GA-X79-UD5 MB. I've encountered some weird problem with getting SMART data or temperature for HDDs. Every single tool I've tried in Windows 7 just can't get any data (HDTune, AIDA64...). I was suspecting that SMART feature is disabled in BIOS but it's seems like there is no such option in BIOS settings. I've even tried to update BIOS but still no luck. Same issue with both controllers on that MB (Intel and Marvell). It seems unlikely that both controllers end up with exact same issue. Both controllers are working in AHCI mode. Is there anythig that can interfere with getting SMART ant temp data from HDDs? Or is there any way to check that it's actuall MB issue? Is it even possible that it is hardware issue since all HDDs seems to work normal despite the fact that I can't get any temperature or SMART data from it.

• Is it possible to use DNX for Nagios with only certain checks

  We have nagios running but can't reach a different network directly. I would like to use Distributed Nagios eXecutor on a dmz server to execute checks in stead of building a new Nagios server and working with passive checks etc. Does anybody know if this is possible to only do checks for some servers through a DNX server?
