[hobbit] Purple trends?

Here is the last couple of entries: [root at nemesis hobbit]# tail -n500 hobbitlaunch.log |egrep larrdcolumn 2005-02-06 09:22:52 Task larrdcolumn started with PID 31987 2005-02-06 09:37:52 Task larrdcolumn started with PID 1026 2005-02-06 09:52:53 Task larrdcolumn started with PID 2544 2005-02-06 10:07:53 Task larrdcolumn started with PID 4059 2005-02-06 10:22:53 Task larrdcolumn started with PID 5565 2005-02-06 10:37:53 Task larrdcolumn started with PID 7087 2005-02-06 10:52:54 Task larrdcolumn started with PID 8589 2005-02-06 11:07:54 Task larrdcolumn started with PID 10117 2005-02-06 11:22:54 Task larrdcolumn started with PID 11629 2005-02-06 11:37:54 Task larrdcolumn started with PID 13143 2005-02-06 11:52:55 Task larrdcolumn started with PID 14648 2005-02-06 12:07:55 Task larrdcolumn started with PID 16168 2005-02-06 12:22:59 Task larrdcolumn started with PID 17868 2005-02-06 12:38:00 Task larrdcolumn started with PID 19396 2005-02-06 12:43:16 Task larrdcolumn started with PID 19959 (the time is now 12:45) I ran the "drop" command and it dropped the trends column but it never came back! I think I may know the cause however...I added the following to the bb-hosts entry for that host: LARRD:iishealth I was trying to get the iishealth graphs to work and I saw a reference to this in the man pages. I apparently Have used it incorrectly. When I removed that reference and restarted hobbit, the trends column came back!(green) What did I do wrong?

Well, it can happen if there have been graphs for this host previously, but now there are none. But that's unusual. Could you check /var/log/hobbit/hobbitlaunch.log for when the "larrdcolumn" task has run ? And if there are any messages logged other than it was started ? Also, try running ~hobbit/server/bin/bb 127.0.0.1 "drop SERVERNAME trends" This removes the "trends" column - it should appear again when the larrdcolumn task runs, if there are any valid graphs.

Purple trends?

I have a strange situation. On only one of my servers, I have the trends column showing purple. When I look at the graphs however, it appears to be up to date! My time and date on the system are also up to date. Anybody got any ideas? Kevin

vmstat graphing with CPU io wait
by tgeorgoulias＠nandomedia.com 06 Feb '05

06 Feb '05

My old BB setup has a customized vmstat-larrd.pl script which allows for variations in vmstat output based on the version of procps. In other words, it compensates for the fact that RHEL3 and old red hat linux systems have vmstat output who's column ordering doesn't match up. So I'd like to bring some of those vmstat changes into my new hobbit setup, most notably the ability to plot CPU wait for IO (wa) alongside user, system & idle time, but poking around in hobbitgraph.cfg doesn't reveal an easy way to do it. Any tips on how I might accomplish this? Tom

Apache tag

Please explain the apache performance tag further. I added the following to my bb-hosts for a host running apache: apache=http://192.168.1.25/hobbit/ It is in fact the hobbit host. I get no apache column or anything related....where did I make my mistake? KEvin

Free software client for hobbit
by manu＠netbsd.org 05 Feb '05

05 Feb '05

Hello I contributed a free software client for Hobbit and BB. It can be obtained from sourceforge's CVS (module hobbitmon/hobbitclient). It's BSD licensed. The thing is written in C, with a OS depedent backend for system info gathering. I wrote the backend for NetBSD. Anyone want to contribute backends for other systems? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu at netbsd.org

[hobbit] temperature-larrd.pl
by GThiesfeld＠webmd.net 05 Feb '05

05 Feb '05

Is this something that is going to be implemented into hobbit in the future? If not, I'd appreciate some help modifying hobbitd_larrd. The only thing I can do with C is spell it:-) I'm not using temperature.sh on the client side, but I can format my script so that the output will match it for consistency.

Do you think temperature-larrd.pl could be modified to run on the Hobbit server and work? Or should I instead attempt to hack the client temperature.sh to send the temp as a data message and then create a do_temp.c module? I looked at converting temperature-larrd.pl when doing the Hobbit larrd stuff, but I couldn't find the script that feeds it - and without some idea of what the input data looks like, it's a bit hard to do the data collection. Where can I find the client side script ? Or perhaps you can just send me a sample of the status it reports. The client script is on deadcat.net - http://www.deadcat.net/viewfile.php?fileid=501 <http://www.deadcat.net/viewfile.php?fileid=501> Here is a sample status message, from my BigBrother server that is using it: logs]# cat *temp green Fri Jan 28 09:13:19 MST 2005 Temperature status: Device Temp(C) Temp(F) ----------------------------------- &green AMBIENT 24 75 &green CPU0 40 104 &green CPU1 40 104 &green CPU2 40 104 &green CPU3 40 104 ----------------------------------- Status green: All devices look okay Status unchanged in 5.12 hours Status message received from 1.2.3.4 Note that the output can vary depending on which kind of machine temperature.sh is run on, but I believe they all have AMBIENT so thats the main value we want to grab and trend Speaking of this, it sure would be nice to have some sort of plugin system, or something for easily creating custom graphs. I can think of many uses for simple one-element graphs (temperature, emails sent per day, etc). You mean doing it in C is too hard :-) Okay ya got me there :P The current work-around is to enable the hobbitd_filestore module to save status- and data-reports to files, the way Big Brother does. There's an option for hobbitd_filestore so you need not save all status logs on disk, but only the ones you want to process with some other tool. Blah...I'm trying to not use any of the backwards compatible features...I want new and improved all the way :-)

[hobbit] Graph Limits

I've worked on this a bit, and so far I've come up with the solution that you can see on my site - e.g. if you go to http://www.hswn.dk/hobbit/servers/ , pick the "cpu" display for the first host, and click the graph to see the 4 periodic graphs. Direct link: http://www.hswn.dk/hobbit-cgi/hobbitgraph.sh?host=voodoo.hswn.dk&service=la At the bottom of the page you can define the lower- and upper-limit for the graph, and which periodic graph you want to see. E.g enter "0.5" in the upper-limit, click "View" and you'll get graphs that cut off spikes at load 0.5. Something like that you had in mind ?

I am not getting any graphs for the iishealth test. I am getting data in the text portion however. What have I missed to get this feature to work? Thanks KEvin
