[hobbit] hobbit monitoring summary report
by bb4＠richter-it.net 02 Dec '09

02 Dec '09

Hello, well you could do a ALLCLIENTS=`$HOBBITSERVERHOME/bin/bb 127.0.0.1 "hobbitdboard"|awk -F\| '{print $1}'|sort -u|wc -l` to get all clients that actually report to your server. As second step do a INSTCLIENTS=`$HOBBITSERVERHOME/bin/bb 127.0.0.1 "hobbitdboard test=cpu"|awk -F\| '{print $1}'|sort -u|wc -l` to get all clients that have client installed monitoring. I assume if a client is installed then it also reports a cpu status. Finally do CLIENTLESS=$((ALLCLIENTS-INSTCLIENTS)). However, clients polled via SNMP are also show the cpu status but have no client installed. But I hope to have helped you a bit. Cheers Torsten Hi, Is there better way of reporting this? Purpose: to report how many active client and client-less monitoring are done by hobbit. My method: 1. for client installed monitoring, count the number of /home/hobbit/data/rrd/*/vmstat.rrd that are recent (ie. newer than a date file created earlier, say 5am) 2. for client-less monitoring, count the number of latest /home/hobbit/data/histlogs/*/conn/ or /home/hobbit/data/histlogs/*/http/ (if both exist, then count only one) that are recent (see def. above). (some clients may not be pingable; multiple web pages on the same server should be counted only once). Thanks, Make your browsing faster, safer, and easier with the new Internet Explorer® 8.

Devmon causing core dumps
by Vernon.Everett＠woodside.com.au 23 Nov '09

23 Nov '09

Hi all Devmon was causing the hobbitd_rrd module to crash and burn. Now this could be a bug, but it could also be a PEBKAC. I am hoping somebody can assist either way. I added a Cisco 2851 to Hobbit, using devmon. Now here is the possible PEBKAC Since Devmon doesn't have templates for the 2851, I used the template for the Cisco 2811. (Network guru told me they are pretty much the same, except for a few extra bells and whistles on the 2851.) The data for the device started appearing in Hobbit, and all looked good. Devmon even created the rrd files for the new Cisco device. However, the hobbitd_rrd module started core dumping, and the Hobbit server page started displaying red for hobbitd_rrd with the crash detected message. See core data below. Took the new Cisco device out of Hobbit, and cores stopped, and life was good again. Is there a significant enough difference between the 2851 and the 2811 to cause this, or are we looking at a genuine bug? I am leaning towards a bug, because even if the collected data was complete rubbish, should it cause the module to core? Regards Vernon My Linux guy reckons this is the important stuff from the core. uname -a Linux las006 2.6.18-92.1.1.el5 #1 SMP Thu May 22 09:01:47 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux cat /etc/redhat-release Red Hat Enterprise Linux Client release 5.2 (Tikanga) gdb -c core.8550 /usr/lib/hobbit/server/bin/hobbitd_rrd GNU gdb Red Hat Linux (6.5-37.el5_2.1rh) Copyright (C) 2006 Free Software Foundation, Inc.

Help with hobbitd_channel and hobbitd_filestore
by tlewick＠tradebotsystems.com 04 Nov '09

04 Nov '09

More digging, this stems from the fact that I was passing channel=client, and hobbit_filestore doesn't support the client channel, at least in the version I have, i.e. 4.2.0 I just tried running: bbcmd hobbitd_channel --channel=data --log=/home/hobbit/data/logs/clientcpu.log hobbitd_filestore --data and that did work. So now it's a question of, how do I get hobbitd_filestore to work with hobbit_channel --channel=client? Modify hobbitd_filestore.c? -----Original Message----- From: Taylor Lewick Sent: Friday, October 30, 2009 10:58 AM To: 'hobbit at hswn.dk' Subject: RE: Help with hobbitd_channel and hobbitd_filestore I think this is a problem with hobbitd_filestore getting/reading the correct file I changed the hobbitd_channel command to: ./hobbitd_channel --channel=client --log=/home/hobbit/data/logs/logfile.txt get_channel_data.pl The get_channel_data.pl was a very simple perl script I wrote just to see if it was getting data from Standard Input. And it worked. The perl script is just: #!/usr/bin/pl $FH="/home/hobbit/data/logs/clientchannel.log": open (OUTFILE, ">$FH"); while ( <STDIN> ) { chomp $_; print OUTFILE "$_\n"; } close (OUTFILE); So clientchannel.log has the output I'd expect to see. And the logfile is no longer being populated with "Our child has failed and will not talk to us... Cause bad file descriptor" messages The only similar post I could find on this was the following thread, http://www.hswn.dk/hobbiton/2006/08/msg00326.html But that was back a few years and was for someone who was running on AIX, and it looked inconclusive. FYI, I'm running hobbit 4.2.0 on a Suse 10.2 server.

Alert mails with the Ack-Code

Hi all Is there an easy way to send alerts without the ACK-CODE? By "easy", I mean not hacking the source code, and not redirecting all mails through a custom script.

Funky TOP output
by ejacobs＠thomaspublishing.com 03 Nov '09

03 Nov '09

Xymon 4.2.3 client running on RHE4 (update 3). When I click on CPU I get the output of top, but it is wrong (Load average may be correct, but list of processes running is not). I checked the data being built in tmp directory on client, and it is wrong there also, so I am sure it has something to do with client.

monitor processes by owner
by josie_wells＠yahoo.com 02 Nov '09

02 Nov '09

Hi, I am new to this mailing list so apologies if I am breaking any protocol by sending this mail out to this address - I have searched the faqs and can find no answer. What I am trying to do is to monitor processes by the owner. In hobbit-clients.cfg I can specify a string to search for in the process name but I can find no way to look in the USER column. If I could, then I could get a count of processes owned by oracle and graph it out. Is this possible? Many thanks Josie

Maintaining original Hobbit / Xymon server
by Tom.Stewart＠landsend.com 02 Nov '09

02 Nov '09

All, We have migrated from our old hobbit server to the new xymon server. We changed platforms, so I'm trying to figure out a way to allow users to view the old data on the original server for the next year or so without having all the tests go purple. Does anyone have any ideas? Thank you for any input. Tom
