http network test
by ralphmitchell＠gmail.com 06 Feb '09

06 Feb '09

I've got a few instances of a.b.c.d www.server.com # http://www.server.com/ and the http column shows up just fine, including the time the test took and a nice graph. The question I was just asked is, is it possible to specify "max response time", so that if the time shown is greater than N seconds I get a red flag?? I don't see a way to set that in the man pages for either bb-hosts or hobbit-client.cfg. Thanks, Ralph Mitchell

Every five minutes and I am getting the following in the rrd-status.log. Host peano is: Hostname: peano.math.purdue.edu OS: Red Hat Enterprise Linux AS release 4 (Nahant Update 6) Linux peano.math.purdue.edu 2.6.9-67.0.1.ELsmp x86_64 I searched the archive and did not find any information about this.

Memory and CPU usage by a process
by vadud3＠gmail.com 21 Nov '08

21 Nov '08

Anyone worked on collecting data and generating rrd and graph for a particular process? I am trying to collect it for all the java processes on one system, which is easy for solaris, and then generate rrd and create graph. With little perl scripts, as provided in rrdtool website, I can generate the rrds as well using the data but how do I tell hobbit server to do the graph? I want to do it all in the server may be by modifying the `ps' script on the client to show the `RSS' column Thanks -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu

[hobbit] hobbitlaunch segfault / timewarp happend again
by dddugan＠iastate.edu 13 Nov '08

13 Nov '08

I recently brought up a new client that has trouble keeping accurate time...so I began encountering this time warp issue. As pointed out by Henrik in January, it is definitely an infinite loop where errprintf() calls getcurrenttime() to get its timestamp. The attached patch modifies the functions in errormsg.c to use time() instead of getcurrenttime(). That avoids any recursion-infinite loop problems, and logs or prints errors with the system's actual time instead of a Hobbit-adjusted-for-sanity time. In the absence of accurate time, I think it would be best to log in the system's time so that you can correlate Hobbit logs with other system logs. Working for me so far, but use at your own risk. Comments? Cheers.

Just comment out the errprintf-statement in lib/timefunc.c: if (timewarphappened) { /* * Tell the world about it. * Must do this AFTER changing timewarp and lastresult, * or we will start an endless loop triggering a stack * overflow because errprintf() calls getcurrenttime(). */ /* * **** prevent segfault: do not log time warp. **** * errprintf("Time warp detected: Adjusting returned clock by %d seconds\n", timewarp); */ } This is not a real solution, but it works for me. Maybe there is somebody out, who can fix this issue properly :-) Regards Alexander > Hi Henrik, > in january I reported a segfault with hobbitlaunch/timefunc.c.

ping intervals
by gleonard＠progrexion.com 13 Nov '08

13 Nov '08

I have some servers that it is critical that I know they are down within at the most a minute to two minutes... hobbit polls every 5min if I remember right? How do I decrease the polling intervals so I can catch these connection problems quicker? Thanks in advance...

no graphs from mpstat
by klomph＠nlr.nl 06 Oct '08

06 Oct '08

I'm trying to setup mpstat to monitor systems with multiple cpu's, but the graphs are not created. Can someone help me with this ? The information is send from the client to the server and in the rrd data directory I have a file called mpstat.CPU2.rrd but there are no values in the last ds (see example) <ds> <name> CPU </name> <type> GAUGE </type> <minimal_heartbeat> 600 </minimal_heartbeat> <min> 0.0000000000e+00 </min> <max> 3.2000000000e+01 </max>  <last_ds> </last_ds> <value> NaN </value> <unknown_sec> 241 </unknown_sec> </ds> the contents of the hobbit_mpstat.hostname.send file is CPUs: 2 CPU0usr: 17.18 CPU0sys: 1.34 CPU0wt: 0.06 CPU0idl: 81.31 CPU1usr: 26.16 CPU1sys: 1.40 CPU1wt: 0.06 CPU1idl: 72.29 And I have copied the rrd_data.pl from the shire and can't find a typo in it. Any suggestions would be appriciated. Regards, Bert Klomp

[hobbit] "Info" column slow on latest snapshot (20080422)
by gumby3203＠gmail.com 23 Jul '08

23 Jul '08

Is anyone else experiencing a slow "info" page load with the 2008-04-22 snapshot? It takes about a minute to load. Also, I get this: Alerting: Alert configuration unavailable Admittedly, I just did an in-line install over the 4.2.0 release, so I don't know if it's just a matter of some configuration file weirdness.

Monitoring FLEXnet License Manager
by annaj＠hi.is 14 Jul '08

14 Jul '08

Would anybody be willing to share their experience in monitoring LEXnet License Manager with Hobbit? I have been doing that, by simply monitoring the network port of the service, and users complain that it is not enough. Allegedly, it seems to continue to listen to the assigned ports, but stops handing out Matlab (...) licenses to the users. For those that have absolutely no idea of what I am talking about, this is a license manager, that among other things, is used for Matlab, Abacus, Maple and other engineering software. It runs as a network daemon, usually on port 27000 or close to that. So before I start rummaging in the shire, and reviving the dead cat, I would like to know if anybody would share their experience on the subject? -- Kindest Regards, Anna Jonna Ármannsdóttir, %& A: Because people read from top to bottom.

CPU % load on Windows XP
by waa-hobbitml＠revpol.com 30 Jun '08

30 Jun '08

We have approximately 20 virtual XP workstations on a VMWare ESX 3.02 server where the bbwin clients on the XP workstations are reporting back to hobbit CPU loads of between 1% and up to 15% or a little more. This seems appropriate for the tiny amount of work they are performing. However, when the CPU load for one of these virtual XP workstations reaches 7% CPU load (as reported on the CPU page), Hobbit sets the color to Yellow. When the CPU load gets to just around 10%-11% CPU load Hobbit sets the color to red. The hobbit-clients.cfg man page explains the default load as follows: Defaults: warnlevel=5.0, paniclevel=10.0 Which I understand to be *NIX load levels, not %loads as indicated by Windows systems. But in the Reports --> Config Reports page, under the CPU for each host I see: UNIX - Yellow: Load average > 1.5, Red: Load average > 3.0 Windows - Yellow: CPU utilisation > 80%, Red: CPU utilisation > 95% So based on that information, I am assuming that the defaults for CPU load on Windows clients is 80% = yellow and 95% = red. Have I done misunderstood? Do I need to add an explicit HOST entry in hobbit-clients.cfg for Windows machines like so: HOST=%^win.* LOAD 80 95 Thanks for any help - especially help that points me to a document that I missed in my searching. :) -- Bill Arlofski Reverse Polarity, LLC http://www.revpol.com/
