Clean up hosts
by josh＠imaginenetworksllc.com 23 Oct '07

I've installed the Hobbit admin tools scripts from http://www.fh-augsburg.de/~henk/hobbit/ and I now have a "Clean host" script. I read the script and while I'm not very knowledgeable on these things I can figure things out for the most part (like why the editor couldn't make a backup - it's always permissions =) and I don't see any action being done in it. Can anyone tell me what this does?

Latest snapshot: comment info missing
by Dirk.Kastens＠uni-osnabrueck.de 22 Oct '07

22 Oct '07

Hi, I just installed the latest snapshot of hobbit. The comment info is missing on my sub pages. The "current non-green system" page correctly displays them, like "xnode5 (mail)". On the mail sub page only the name "xnode5" is displayed, without the comment "mail". -- Regards, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470

Monitoring raid in addition to filesystem
by josh＠imaginenetworksllc.com 19 Oct '07

19 Oct '07

I'm looking at one of the demonstration Hobbit servers here: http://tyge.sslug.dk/hobbit/bb.html I noticed that the www.linuxforum.dk host has a raid column - is this a server or a client configuration? I'd love to do this on my Hobbit clients. The test done on those two hosts are using Linux software raid, I believe, which is also what I am using - does this raid test expand beyond this?

Client based configuration & disk graphs
by tk＠westend.com 19 Oct '07

19 Oct '07

Hi, is client based configuration fully supported or is it considered deprecated? Are there some features which do not work using client based configuration (e.g. logfile monitoring or viewing client data in the web interface)? I've noticed that the disk graphs do not show all filesystems reported by the clients. There is always one filesystem missing (count in the script URL one too low). However on the trends page the graph shows up correctly. Is it a bug or configuration issue?

Question about bbcombotest
by hhuseman＠materna.de 18 Oct '07

18 Oct '07

Hi, I'd like to use bbcombotest to monitor a HA-system which runs in failover-mode, i.e., the processes have to run on one of the servers, but they may not run on both. I've added a rule to bbcombotest.cfg, this works fine and the combined test shows green when one of the servers is okay, as I expected. But, since the processes are not running on both servers, hobbit shows the backup server as "red" because of missing procs, which is a bit confusing. So, I tried to use NOCOLUMN=procs in bb-hosts for the two servers, but then, hobbit stops monitoring the processes completely, and do not show the procs in the combined test, too. Hm, I'm wondering how I can define this?? I'd like hobbit to stop monitoring the processes independly, and only show the combined status as defined in bbcombotest.cfg. Thanks, and have a nice hackin', Harald -- Harald Husemann Netzwerk- und Systemadministrator Operation Management Center (OMC) MATERNA GmbH Information & Communications Westfalendamm 98 44141 Dortmund

Not able to see any web pages other than home page of Hobbit of my server
by haresh.k.shah＠ge.com 18 Oct '07

18 Oct '07

Hi, I had installed hobbit successfully and now i am trying to configure it. I am able to see my homepage and the host's services on it. but when i clicked on any of the link then i got the error as 500 (page can't be displayed). I use apache as web server. [ I am using solaris 5.8 ] My error log looks like this : ld.so.1: hobbitsvc.cgi: fatal: libpcre.so.0: open failed: No such file or directory [Thu Oct 18 05:35:20 2007] [error] [client 10.209.15.1] Premature end of script headers: bb-hostsvc.sh, referer: http://test.hobbit.com:8080/hobbit/ I add necessary library in apache or even i tried - LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/local/rrdtool-1.2.2 3/lib:/usr/local/ssl/lib I also follow this link - http://hswn.dk/hobbiton/2006/08/msg00504.html and after running /usr/local/bin/gdb /home/hobbit/server/bin/hobbitsvc.cgi /tmp/core command I got the following : GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc.

Program terminated with signal 11, Segmentation Fault. #0 0x34190 in hobbitenv () I tried "crle -s" command to add the above library. but some how it not make any difference. I saw the log from hobbit side and it not throw any abnormal messages. what could be the reason? I configure alert and i am able to get the alert as well but not able to see any page other that hompage of my hobbit monitor.please let me know whether problem is from apache or something else? Thanks Haresh

monitoring large log files--does SIZE setting in clients-local.cfg affect parsing?
by tomg＠mcclatchyinteractive.com 17 Oct '07

17 Oct '07

I'm trying to monitor a log file that gets pretty big--right now it's 14MB and won't be rotated until this evening, when it'll probably be 35MB. I would like to ensure that the hobbit client catches each and every time it runs across a line that contains WRN or ERR, but it seems like it keeps missing it and I'm wondering if the file just grows too quickly for the config I'm using. The parsing should be pretty easy, since nearly every line that we don't need to worry about contains "MSG:" after the time stamp. Here's a snippet: [10/17/07 16:14:50] - MSG: ================================================ [10/17/07 16:14:50] - MSG: ================================================ [10/17/07 16:14:50] - MSG: Processing dispatched check queue [J: 0] [10/17/07 16:14:50] - MSG: Handling 2 jobs [10/17/07 16:14:51] - MSG: Handling 2 jobs [10/17/07 16:14:51] - MSG: Handling 1 jobs [10/17/07 16:14:52] - MSG: ================================================ [10/17/07 16:14:52] - MSG: Processing run queue [J: 2] [10/17/07 16:14:52] - MSG: Generated available worker list [W: 4] If a line had WRN, I'd like to get a yellow alert. If ERR, red. Here's what I've got in my clients-local.cfg for this class of servers: [linux] log:/secret/path/app.log:10240 ignore MSG: Here's the hobbit-clients.cfg entry: LOG /secret/path/app.log WRN color=yellow LOG /secret/path/app.log ERR color=red The logfetch.<hostname>.cfg file gets propagated to the client, so that works correctly. I thought that my configuration would send every line from /secret/path/app.log that wasn't there the last time the hobbit client ran the test and that doesn't contain "MSG:" into the Hobbit server, as long as the total amount of log data doesn't exceet 10240 bytes. Then the hobbit server would parse that incoming data and look for two regex, WRN and ERR, and change color accordingly. However, I can grep through the logs and find instances of lines with ERR that weren't noticed by the Hobbit server. Is the LOG size of 10240 restricting the amount of data that the client processes or is there something else happening that I don't understand? Any help is appreciated. Thanks, TOm
