change check frequency for one client only?
by jjj863＠gmail.com 03 Nov '06

03 Nov '06

I had a stability problem with a client where the disk may become inaccessible. We have a test plan but needs something to detect whether the disk is writable every minute. Hobbit is running on it. So, if I can adjust the check frequency for this client alone to 1m instead of the default 5m, hobbit checks would fail then alert us, since hobbit clients needs to write temp files. Actually, this was how we get alerted yesterday.

Enable/Disable command

Does the bb enable/disable command accept multiple tests to act on, eg; bb 127.0.0.1 "disable hostname.(cpu|disk)" or do the commands need to be issued separately? -- Rich Smrcina VM Assist, Inc.

New Hobbit stuff: Scalability and H/A work
by henrik＠hswn.dk 02 Nov '06

02 Nov '06

A couple of weeks ago, I was asked if our Hobbit system at work could handle monitoring of one more customer. Of course, I said - no problem. Well, there was one gotcha: This customer has 1100+ servers that need to be monitored. Which means my Hobbit installation is about to double in the number of hosts monitored. Hmm ... This will be interesting to watch. I am fairly confident that Hobbit can handle it, with one exception: The disks on my Hobbit server will be overloaded. It already spends about 50% of it's time in I/O wait, so doubling the number of hosts with cpu/memory/disk etc. graphs will probably crash it. So something needs to be done - fast: These hosts should go into our Hobbit before Christmas. That is why I currently may seem a bit absent from the mailing list. The way I plan to handle it will be by distributing the load of RRD updates onto several servers, each handling a subset of the total set of hosts; Hobbit will automatically detect which of the 3 RRD-servers handles a specific host and direct rrd-updates to that server. New hosts are distributed across all of the RRD servers in a weighted round-robin fashion. The way this is going to be done means that it can be used not only for distributing the load of the RRD file updates, but also for distributing the other hobbitd_* modules (alerting, history logs, client data processing etc). In other words, this will be a major win for Hobbit in large installations. It also has one more benefit: I think this can be evolved to handle automatic failover, so you can run multiple Hobbit servers that process the same data - meaning all of the on-disk data will be identical across all of the Hobbit servers. This should make it possible to setup a group of Hobbit servers for very high availability of the monitoring system. I haven't worked out all of the implementation details yet, but I think it is possible. Regards, Henrik

I decreased the bbnet test from 5 minute to 2 hrs. This is one thing I dare not do on BB server.I did it on my test server ;) Am I missing anything to adjust the bbnet check interval ?I am starting to see gap on all the trending graphs. [bbnet] ENVFILE /opt/hobbit/server/etc/hobbitserver.cfg NEEDS hobbitd CMD bbtest-net --report --ping --checkresponse --dnslog=$BBSERVERLOGS/dns.log --concurrency=1000 LOGFILE $BBSERVERLOGS/bb-network.log INTERVAL 120mT.J.

Well, I got all lots of purple icons now. it now make sense since the hobbit system work around 5m interval.So the question is what is the maximum interval without triggering the purple icons ?T.J.

Hosts going purple
by jeffnewman75＠gmail.com 02 Nov '06

02 Nov '06

Hi, I am running the latest hobbit server/client (with all the patches applied) and I still have AIX hosts going purple due to the netstat command (nearest I can tell) >From ps: # ps -ef | grep hob hobbit 13306 16692 0 03:58:28 - 0:00 sh /usr/local/hobbit/client/bin/hobbitclient.sh hobbit 15572 13306 0 03:58:28 - 0:00 sh /usr/local/hobbit/client/bin/hobbitclient-aix.sh root 16262 12252 0 11:07:52 pts/0 0:00 grep hob hobbit 16692 1 0 Oct 30 - 0:03 /usr/local/hobbit/client/bin/hobbitlaunch --config=/usr/local/hobbit/client/etc/clientlaunch.cfg --log=/usr/local/hobbit/client/logs/clientlaunch.log --pidfile=/usr/local/hobbit/client/logs/clientlaunch.devarb2.pid hobbit 18104 15572 64 03:58:29 - 206:41 netstat -an hobbit 20870 15572 0 03:58:29 - 2:55 grep ^tcp If I go on that host (which is purple right now) and run "netstat -an | grep ^tcp" it runs just fine. This happens mostly on AIX 4.3.3 There is nothing in any log file on the client to indicate any problem. Can provide any needed info. Thanks, Jeff

Too many tests for one host
by ndorfsman＠gmail.com 02 Nov '06

02 Nov '06

Hi, I'm currently working on bb-roracle test (I'll post the new version on deadcat, probably with NCV numbers). It's raising an issue which I did't think about....I will have too many test to display for one host without horizontal scrolling ! Does anyone ever meet this ? Any idea to go against that ?

Ignoring proc alerts in the default section
by JamesHorwath＠glic.com 02 Nov '06

02 Nov '06

All: I have a default section in my /etc/hobbit/hobbit-alerts.cfg with something like this: PROC my_process PROC his_process I have a couple of servers that do not run the processes my_process or his_process and as a result they are showing errors because of the definitions in my DEFAULT section. How can I have a server ignore the default section? If I have 99.9% of the hosts using the 2 process and only 2 or 3 which don't, any suggestions on how to handle it?
