[hobbit] no iostat rrds?
by craig＠cookitservices.com 13 Mar '09

13 Mar '09

iostat graphs on Solaris in hobbit are broken. http://www.hswn.dk/hobbiton/2007/07/msg00335.html Even after these patches there seems to be a parsing issue on some filesystems. ie. some filesystems get a solid graph line, some filesystems are a broken line. "Random" data seems to be missing from the rrd's. I have not located where the bug is yet though. Craig Cook

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

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

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...

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] "Hobbit" name legal stuff; slight name change will happen

Hobbit is the name of a species in J.R.R. Tolkiens stories, and it is only named in his stories. There are other things like the Shire that are associated with those that are somehow associated with Hobbit Monitor, and that might give some similarities to thoes stories. There is however a mythology that those stories are built upon, a mythology that is in the public domain. Even though I personally like the name Hobbit Monitor best, or Hobbitmon, the name Gandalfr Monitor, could be an option to be considered. The name Gandalfr and the name Elf or Alf are much older than Tolkiens work, dated back to about the year 1300 AD in Völuspá and the Elder Edda by the icelandic authors. See: http://www.nationmaster.com/encyclopedia/Gandalfr The Old Norse name "Gandalfr" appears in the list of dwarves in the Völuspá of the Elder Edda; the name means "wand-elf." Tolkien took the name along with the dwarves' names when he wrote The Hobbit in the 1930s. He came to regret the creation of this "rabble of eddaic-named dwarves, [...] invented in an idle hour" (The Return of the Shadow:452), since it forced him to come up with an explanation of why Old Norse names should be used in Third Age Middle-earth. Meaning Of Names In The Lord Of The Ring - Anders Andersen's WebLog (324 words) In an Old Norse poem, Tolkien found a list of dwarf names which included "Gandalfr." Since alfr means "elf," he began to wonder what an elf was doing in a company of dwarfs. Tolkien interpreted the first element ("Gand") of "Gandalfr" to mean "wand." This gave Tolkien the notion that Gandalfr must be a sorcerer-elf who possessed a magic wand or staff. Gandalfr, he theorized, must have joined the band of dwarfs to obtain some special sort of magical plunder. -- Kindest Regards, Anna Jonna Ármannsdóttir, %& A: Because people read from top to bottom.

[hobbit] Why the next Hobbit release hasn't happened yet

I agree there's been a lot of good support, but a few issues I don't think any of us have been able to solve. I guess I speak with bias here, having a few myself (the HTTP test time reporting issue, the RECOVERED alert problems). I hope life becomes a little more settled, would like some of your insights on the tough stuff. -Alan
