How to make defaults only for a subset of hosts

Can a rule be applied to DEFAULTS so the default settings only apply to a class of hosts? Thanks, Steve Holmes

[hobbit] Server-side extension scripts: shell vs. C programming
by gumby3203＠gmail.com 29 Jun '07

29 Jun '07

I remember reading somewhere in the Hobbit documentation that when an extension script starts to do a lot of things, it should be coded in a compiled language such as C, instead of as a shell script. I have a custom script that takes a lot of data and converts it into NCV graphs, and I believe it is at the point where I should consider rewriting it in C. Before I get to far into it, is the hobbitd_sample.c something that I should look at for this? I'm not sure if I'm reading the documentation on it correctly, if it is a good example for an external script. Has anyone else had experience in needing to convert a shell script to C/C++/etc for Hobbit? I'm just trying to get a rough idea of how much effort this will require.

Lost cpu graphs of Hobbit server
by jwprkr＠gmail.com 29 Jun '07

29 Jun '07

Hello, I'm a old BB user that's a new believer in Hobbit. I'm having an unusual problem I didn't see a reference to anywhere. About a day after I started the Hobbit server, I noticed that no more data was being added to the cpu RRD graph of the Hobbit server. It worked at first, but just stopped. I tried removing the RRD file to try to re-create the file, and no new file was created. I also noticed that the user/process graph also stopped updating for this machine. All other graphs are working fine for this machine and for all other machines. Has anyone seen this? Thanks in advance, Jeff Parker -- Jeff Parker jwprkr at gmail dot com

Orca in Hobbit
by Larry.Sherman＠rbsgc.com 28 Jun '07

Hi, My colleges in London have asked some of out Linux SA's to install Orca to monitor some of their boxes. I know that 4.2 has the rudiments of integration between Orca and Hobbit, and was wondering if any of you have got it working...

rrd error messages
by sjh＠allegro.ics.purdue.edu 28 Jun '07

28 Jun '07

Greetings, I am getting a lot of errors in the rrd-status.log file. There are 2 actually that are appearing at an alarming frequency (and have been for quite a while): 2007-05-21 09:42:52 RRD error updating /var/hobbit/data/rrd/client.purdue.edu/disk,export,video.rrd from 128.210.xxx.xxx: unknown consolidation function '^?<F8>' 2007-05-21 09:42:52 RRD error updating /var/hobbit/data/rrd/client.purdue.edu/memory.real.rrd from 128.210.xxx.xxx: illegal attempt to update using time 1179754972 when last update time is 2146959360 (minimum one second step) Note that the system time on the hobbit server and on the clients are all synchronized with xntpd so the clocks aren't different. I am also having some trouble with a lot of NAN values in the disk history graphs. I'm wondering a) how to fix these errors, and b) if the errors have anything to do with not getting good data in the graphs. Thanks, Steve Holmes

Why no columns "cpu","disk","procs", "svcs" displayed for Windows 2003 clients on web page of hobbit server?
by casedj＠21cn.com 28 Jun '07

28 Jun '07

Hobbit server 4.2.0 running on RHEL4, BB client 1.08d on Windows 2003 servers. There're no such columns displayed , e.g. "cpu","disk","procs","svcs" for Windows 2003 (servers) clients. Only three columns, or "conn", "info","trends" displayed. no firewall between them. Some parameters dismatched? connection parameters on client are default as below: IP Port:1984, Timer:300,Logs Timer:60 But one Windows XP client looks like ok, almost same parameters. Any suggestion will'be appreciated. Regards, Case

Hi, I would like to setup a view similar to the "non green" view, but only for certain hosts/tests/status combinations. Can anyone point me to examples or documentation regarding this topic. Thanks ! -Dan

Cluster monitoring (proxy setup)
by fensterb＠ccri.net 27 Jun '07

27 Jun '07

The more I read through the archives, the more confused I am on how to implement this. Basically, I want to monitor 64 compute nodes that are on a private network. I do not want to have to install the client on all of the nodes as all I care about is the ping test. I have a main hobbit server that I want to merge the info from the cluster and from various other systems that I monitor. To work as a bridge, I installed hobbit on the head node of the cluster as it is the only system with an interface on both networks. On the head node I disabled all of the hobbitd modules and setup bbproxy to forward messages to my main hobbit server. This didn¹t work. After reading up on the bbproxy man page it looks like bbproxy is really meant to forward client messages on to a bbdisplay. Since I don¹t have the hobbit client installed on the compute nodes it doesn¹t sound like bbproxy will work for this. I am a bit confused on what actually does the network tests. Do I have to have hobbitd running on the head node in order for the network tests to run? If that is the case, how do I get hobbitd to forward information on to a different hobbit server? I am pretty sure that I have simply failed to understand one of the man pages or something, but I cant seem to figure out how to accomplish what I am looking to do.
