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.

Main view alphabetical sorted?
by toberkel＠toberkel.net 26 Jun '07

26 Jun '07

Hi, I have a little question. Is it possible to have it sorted alphabetically? But not by hand in the bb-hosts file, I need it automatic. But I don't use group-only, I use always group-compress in my bb-hosts file. Is this possible? Kind regards, Tobias Riewoldt

I'm getting the error "could not lock RRD"
by dninja＠gmail.com 26 Jun '07

26 Jun '07

Hi I've just installed hobbit 4.2.0 on an archlinux box with rrdtool version 1.2.23-1. Looking at the logs I'm getting the following error every 30 seconds or so as it tries (I assume) to create the graphs: 2007-06-22 19:24:55 RRD error updating /var/sites/hobbit/non-secure//data/rrd/xxx/procs.rrd from 192.168.0.2: could not lock RRD I've googled and searched the archives but can't find any other mention of this error. Can anyone suggest a solution? Thanks Robin

hobbitfetch replacement with ssh
by haertig＠avaya.com 26 Jun '07

26 Jun '07

I'm still thinking about my hobbitfetch/msgcache replacement I asked about a few weeks ago. Using only ssh from the Hobbit server. Client machine is out in DMZ, thus unable to talk to Hobbit server. I cannot run a listener (msgcache) on the client (policy reasons, not technical ones). Here are my thoughts. Maybe someone can expand on them or suggest a different approach. (1) Run normal Hobbit client on DMZ machine. (1a) Client appears to collect data just fine into ~hobbit/tmp/msg.XXX.txt (1b) Client would try to connect to Hobbit server to transmit this file, and fail. Fine. Let it fail. It appears to do so gracefully. Question: Any simple way to make it stop trying to connect and still behave gracefully? chmod 000 ~hobbit/bin/bb? Change BBDISP="" in ~hobbit/etc/hobbitclient.cfg? (2) Create a Hobbit server script to use socks/ssh to retrieve that ~hobbit/tmp/msg.XXX.txt file from the client machine (it's trivial to write such a thing) (3) Have this server script feed the raw data retrieved in step (2) into the Hobbit listener (which would be localhost:1984), such that it appears to the Hobbit listener the data came in from the client computer in the normal manner. Step (3) is what I don't quite know how to implement yet. I'm familiar with using the bb command to send messages, but those are formatted messages, not raw data as would be present in the retrieved msg.XXX.tmp file. I want to assure that the guts of the Hobbit server processes this proxied client raw data just as if the client had sent it instead of my custom server script. Is there some trivial way to accomplish (3) that I'm just missing searching through the man pages? I could have my custom server script parse the raw data itself and then create individual Hobbit messages (to send via the bb command), but that sounds like I'd be reinventing the wheel. Hobbit server processes already know how to parse this data ... if I could just tap into that part of it. Thanks!

hobbitfetch with Windows clients
by b-kennedy1＠raytheon.com 26 Jun '07

26 Jun '07

Hi. Is there a way to have the Hobbit server pulldata with hobbitfetch from Windows Hobbit clients? We have Windows and Solaris clients behind a firewall and ports 1984, 22, 80, and 443 from the Hobbit server to the clients are the only ones opened, nothing from the clients to the server. Hobbitfetch is working perfectly for the Solaris clients, so I was hoping to do the same thing for the Windows. Any ideas would be greatly appreciated. Regards, Bryan Kennedy

Host URLs without bb-notes
by shea4th＠comcast.net 25 Jun '07

25 Jun '07

Hi all, I have a handful of machines that have a URL to hit for remote access. I thought it would be great if I could embed the URL in the host column. So like any good hobbit, I check the mailing list first, but everything I found mentioned bb-notes and --docurl. I didn't want hyperlinks for every host, just the few I mentioned earlier. While this is not the prettiest of solutions, it works for me and wanted to share with the community. I use a carefully crafted COMMENT tag in the bb-hosts file like: 10.10.10.10 HOST01-RA01 # testip https://10.10.10.10 COMMENT:"<AHREF=https://10.10.10.10/ target=_new>URL</A>" Sincerely -Grs- Gregory R Shea EMC Corporation

help with freemem on Aix43

Hi all, Just wanted to put some closure on this, just in case someone else misinterprets the vmstat output. I was supposed to divide by 256 not 1024. A humbled hobbit -Grs- Gregory R Shea EMC Corporation -------------- Original message -------------- From: shea4th at comcast.net Hi all, I'm having some trouble with the freemem on an aix4.3 client and need some help.
