NFS and shared clientlaunch.cfg files

Greetings fellow Hobbit-ers, I was recently tasked with monitoring 100+ solaris systems. Feeling undaunted I reached into my trusty IT toolbox and pulled out one of my favorite tools, Hobbit. What I encountered is as followed. The systems utilize NFS mounted directories. I installed the client files into /usr/local/ hobbit/client and voila! they were available to all of my systems. The issue that I encountered was that I wished to run different external scripts per client, but with a "shared" clientlaunch file I could not see how to do this. (This is where I cringe as I suspect that my solution is rather naive) What I would up doing is modifying the runclient.sh file as reflected below: ~/client hobbit$ diff runclient.sh runclient.ren 79c79 < $0 --hostname="$MACHINEDOTS" stop --- > $0 stop 83c83 < $HOBBITCLIENTHOME/bin/hobbitlaunch --config=$HOBBITCLIENTHOME/etc/ clientlaunch.cfg --log=$HOBBITCLIENTHOME/logs/clientlaunch.log --pidfile= $HOBBITCLIENTHOME/logs/clientlaunch.$MACHINEDOTS.pid --- > $HOBBITCLIENTHOME/bin/hobbitlaunch --config=$HOBBITCLIENTHOME/etc/ $MACHINEDOTS.clientlaunch.cfg --log=$HOBBITCLIENTHOME/logs/ $MACHINEDOTS.clientlaunch.log --pidfile=$HOBBITCLIENTHOME/logs/clientlaunch. $MACHINEDOTS.pid 102c102 < $0 --hostname="$MACHINEDOTS" stop --- > $0 stop 107c107 < $0 --hostname="$MACHINEDOTS" --os="$BBOSTYPE" start --- > $0 start My questions are as followed. Has anyone encountered this specific issue before, and if so how did you address it? Does my, admittedly inelegant, solution pose any issues in relation to long term use? I searched the list and was unable to find anything specific to my issue. Thanks in advance for reading this missive. Best regards, Mike

cupsd

For those who want to monitor a cups print server, here's a definition you can put in your bb-services file: [cupsd] send "GET /printers\r\n" expect "HTTP/1.1 200 OK" port 631 Alternatively, you could just use http://host:631/printers in your bb-hosts file. The cupsd is, for monitoring purposes, a web server. -Jeff "Fun with Users #1: ln -s /dev/random /etc/motd"

Greetings and a question...

First off, I love Hobbit. A lot. I've been running it as a test in our department for almost 9 months now and I have convinced the boss to not renew the contract for our proprietary monitoring package (from a certain other Scandinavian country) in favor of using Hobbit. I just need to see if I can put donations on my corporate card. :) But I do have one last question after all of that effusion. Is anyone out there running dbcheck.pl and had this error: "Wed Jan 23 10:21:40 2008:ERROR on sid_name: Timeout connecting to DBI:Oracle:sid_name!" I know it isn't a network problem because the hobbit user can connect using sqlplus just fine and the oratns check is OK. The required Perl modules installed OK... I think. (no, sid_name is not our SID, name has been changed to protect the innocent) Thanks! -- --Ben Benjamin P. August System Administrator - VPUE Stanford University

[hobbit] strange graph behavior - random machines & graphs
by gumby3203＠gmail.com 07 Apr '08

07 Apr '08

I'm almost certain now that this is a problem when Hobbit/rrdtool doesn't receive data when it is expecting it. In short, it seems that when a lack of data occurs, instead of assigning NaN or 0, this huge number is inserted into rrd database instead. I'm still not sure where this number is generated from, though.

FW: [hobbit] tooltips, current snapshot 15-Jan-08
by david.gore＠verizonbusiness.com 31 Mar '08

31 Mar '08

Still hoping this could be fixed soon? Having to scroll the bb2 page for hosts with long descriptions like contact and vendor info is a pain. I still do not really understand why this is only a problem on the bb2 page. ~David _____ From: Gore, David W (David) [mailto:david.gore at verizonbusiness.com] Sent: Thursday, November 15, 2007 14:20 To: hobbit at hswn.dk Subject: RE: [hobbit] tooltips In regards to the hobbit snapshot: They say a picture is worth a thousand words. If the list server allows it, I have attached an image of my bb2.html page. bb2 is our primary view and, as you can see from the image, tooltips pushes all the hobbit columns out of the view to the right. Tooltips are the text you see when you hover over items like the smiley's in hobbit? I suppose it has always worked well for the little smiley gif icons, just not so well for the bb2 host links where it seems to add the tooltip to the hostname rather than create floating text. ~David _____ From: Johann Eggers [mailto:Johann.Eggers at teleatlas.com] Sent: Thursday, November 15, 2007 13:11 To: hobbit at hswn.dk Subject: [hobbit] tooltips Re: the tooltips issue: Isn't it useful to make this an option whether they should be displayed on the bb2 page or not? I really like the tooltips but I agree with David that they will clutter your bb2 page so that this page is not longer usable. Johann _____ From: Gore, David W (David) [mailto:david.gore at verizonbusiness.com] Sent: Donnerstag, 15. November 2007 13:47 To: hobbit at hswn.dk Subject: RE: [hobbit] stale alerts I am running 4.2.0 with the allinone patch. I do have a suspicion that external server side scripts could contribute to the stale alerts. In my case, specifically a script that ssh's to a remote host and executes a shell script on the remote host. It may also happen in conjunction with these errors in the logs, which someone else recently reported: page.log.1:2007-11-05 16:20:53 hobbitd_alert: Got message 14425, expected 14424 As soon as the issue with tooltips is resolved, I will be moving our primary hobbit to the snapshot release. The snapshot, seems much better, but with tooltips and host descriptions pushing our display to the far right of the screen we cannot use it right now. ~David

Checking process longevity
by Colin.Coe＠woodside.com.au 20 Mar '08

20 Mar '08

Hi all I'm trying to work out how I can get hobbit to alert me when a process has existed for more than n seconds. This is important as we sometimes have NFS problems that cause processes such as df to hang due to stale mounts and I'd like tp pick these up sooner rather than later. Any ideas on how to implement this? Thanks CC NOTICE: This email and any attachments are confidential. They may contain legally privileged information or copyright material.

SCRIPT and MAIL not working
by leam＠reuel.net 17 Mar '08

17 Mar '08

New to Hobbit so I assume my config is off. We're using Hobbit 4.2.0 on Solaris 9 and I'm running into a couple issues. Neither MAIL not SCRIPT are working in the hobbit-alerts.cfg. Our Hobbit server was moved from a Linux host to the Solaris one, and regular mail works on the Solaris box. However, I can't get MAIL or SCRIPT to work to send alerts when I'm using: bbcmd hobbit_alert --debug --test <server> <service> I can see it getting logged, but MAIL and some of the admin scripts seem bash-centric and not Bourne shell compatible. The script I have just sends mail and works if I run it as the hobbit user. Help would be much appreciated! Leam

hobbit color-changing issue
by georgi.lalev＠zdv.uni-tuebingen.de 17 Mar '08

17 Mar '08

Hello, I have a small hobbit issue. I want hobbit to go red every time the word "/evicted/" shows up in /var/log/messages on some hosts. So the part in /hobbit-clients.cfg/ is as follows: HOST=%cn4[3-6]*-hp PROC "%syslogd" 1 1 red PROC "%/usr/sbin/nscd" 1 red PROC "%iscsid" 2 2 red LOAD 16.5 20.0 LOG %/var/log/messages %(?-i)evicted|Oops|ALERT|NOTICE COLOR=red LOG %/var/log/messages %(?-i)LustreError|WARNING|FAILED|kernel|failing|ILLEGAL COLOR=yellow The Part in client-local.cfg: [cn44-hp] log:/var/log/messages:10240 ignore MARK trigger ALERT trigger .*(dumping log to)|(evicted).* file:/var/log/messages The Issue: Every time I put the word "/evicted/" manually in the messages file, hobbit will go red for about 15 minutes. That's fine. If I put a second line with the word "/kernel/" in the messages file, a second (yellow) line appears in the mesgs column. That's also fine. Hobbit is still red, but stays that way only for about 15 minutes. After the 15 minutes, it changes to yellow and the "/evicted/" warning is gone. It stays yellow for another 15 minutes, and then it turns green. The messages file is really small (under 10 KByte) and not much is being written in it. That's why hobbit must stay red all the time!?! I searched for the number 900 in server/etc, but nothing matches (exept some proxy configuration). Does anyone have an Idea what or where the problem could be? Greetings Georgi
