ignore certain things in a log file

Could somebody tell me why this won't work? HOST=testserver LOG %/var/adm/messages kern "IGNORE=%(corrupt label|wrong magic number)" Trying to ignore all lines in the messages file that contain those key words.

varnish, sphinx and nfs client
by tseglard＠tf1.fr 26 Aug '10

26 Aug '10

Hello ! I'm in charge of a platform with a lot of different technologies. Of course, I deployed Hobbit/XYmon to monitor everything but, for now, I can't find < modules > for Varnish, Sphinx nor a good NFS tests. It's too bad because Munin is here too and has such tests. So I'm starting to port these scripts for Xymon but I prefer to ask before I'm going further to this J Cheers, Thomas SEGLARD

Figuring out the ntp(date) check
by Carl.Melgaard＠STAB.RM.DK 25 Aug '10

25 Aug '10

Hi, I was trying to figure out, how the ntp-check works, as I sometimes get a "no server suitable for synchronization" error when performing this check. Im not much of a C-coder, so I have why this line is triggered in the code from bbtest-net.c below: void run_ntp_service(service_t *service) { testitem_t *t; char cmd[1024]; char *p; char cmdpath[PATH_MAX]; p = xgetenv("NTPDATE"); strcpy(cmdpath, (p ? p : "ntpdate")); for (t=service->items; (t); t = t->next) { if (!t->host->dnserror) { sprintf(cmd, "%s -u -q -p 2 %s 2>&1", cmdpath, ip_to_test(t->host)); t->open = (run_command(cmd, "no server suitable for synchronization", t->banner, 1, extcmdtimeout) == 0); } } } Can anyone explain under what conditions that phrase occurs? Regards, Carl Melgaard

Truncated email alerts
by mark.stoltzfus＠pmigroup.com 24 Aug '10

24 Aug '10

All, has anyone seen an issue where email messages that Xymon generates (NOTE: not the client status on the webpage, which is complete) are getting truncated beyond a certain length? We had already bumped up MAXMSG_STATUS and MAXMSG_CLIENT for a different issue (where the status messages going to the server were getting truncated), but this is different. For example, an alarm gets generated, and on the xymon webpage, you can see the entire status. The email we receive, however, is truncated. We're running Xymon 4.2.3 on RHEL5. We're trying to track down what layer this at, and it's proving a challenge. We're seeing this across different alarms, but they all seem to get truncated around 6kb. Regards, Mark

Is it just me, or do i really keep bumping into references to theshire which no longer exists as far as i can ascertain? Even the wiki and xymon.com reference this site which is pretty poor form. How do we go about getting this removed. And where is the repoistory of add-ons now? This message is intended for the addressee named and may contain confidential information.

Fwd: RE: New install, no hosts shown - Never Mind
by joea＠j4computers.com 23 Aug '10

23 Aug '10

For the sake of completeness, and for those searching archives for a similar issue, I should add that - The IP address, being embedded in so many "binary" files, made it necessary to delete everything in /home/xymon/client and /home/xymon/server, for the recompile to be effective. joe a. >>> Removed dark glasses. Noted logs indicated typo in host IP. Recompiled. Working, so far, as expected. joe a. In a new install of xymon, the base web page displays, but none of the hosts listed in bb-host will show. Not even the default host. Obviously, I have something mis configured. Thanks in advance

Adding a custom RRD to graphs and monitoring

Ok so after that convoluted message, I ended up having much more success after hacking at it some more.

From: Matthew Moldvan/GIS/CSC at CSC To: xymon at xymon.com Date: 08/19/2010 04:00 PM Subject: [xymon] Adding a custom RRD to graphs and monitoring All, This is stressing me out, hopefully someone takes the time to go through my ramblings below and help me out. Lots of information so please bear with me. For the past few days I've been trying to add a custom script (iostat information) and have the data graphed, but I'm not having any luck (mostly due to not understanding the RRD definitions in hobbitgraph.cfg). I've read through a ton of the how-tos on the subject, but all of them seem to vary a bit on the details. My resulting graphs look like this: http://imgur.com/4Nwrp.jpg So far I've got a script running on two systems reporting data back to the main page. This brings up my first question: When sending information to be graphed, is the data passed in as a bb status message or a bb data message? I thought I had it working at one point by sending similar data below through a status message, but I'd like to pass only a status message and HTML through the "bb status" command and keep the actual data passed for the RRD in the "bb data" command if that works. I also tried wrapping the data below in HTML comments as below, but no luck. "" Sample data: c1t50060E80104AAE50d1 : 0.82 c1t50060E80104AAE50d2 : 0.07 c1t50060E80104AAE50d3 : 1.71 c1t50060E80104AAE50d4 : 0.46 c3t50060E80104AAE52d0 : 1.31 c3t50060E80104AAE52d1 : 1.53 c3t50060E80104AAE52d2 : 0.09 c3t50060E80104AAE52d3 : 3.14 c3t50060E80104AAE52d4 : 0.61 c3t50060E80104AAE52d12 : 0.06 c0t0d0 : 11.70 c1t50060E80104AAE50d0 : 0.87 I've seen it both ways in the examples. I tried sending both, but that doesn't seem to be working. From what I understand if I specify a test as NCV in the TEST2RRD section, one of the running processes (hobbitd or hobbitrrd) will read in the "name : value" pair and pass that to an RRD update/create command? Does that require integer values or are floating point up to a certain precision acceptable? Currently I'm passing .2f from the nawk script and getting a bunch of "nans" in the RRD output (could be various reasons, though).

Fwd: bb-hosts, host names
by joea＠j4computers.com 23 Aug '10

23 Aug '10

Something like that, yes. Or, just the name changed, as there seems to be a space/formatting issue looming. But, I cannot seem to get either NAME: or COMMENT: to take effect. Obviously, I have not grasped the syntax from the man page. BTW, any hints on how to get list mail sent to me would be appreciated. I had to resort to to the archives to find this. Must be in digest mode, by default. And, thanks for the prompt replies. Feel free to reply direct to me, as well, for now. joe a. >> If you're trying to get something descriptive on the display line for each host, see the COMMENT tag in the bb-hosts manpage. "Description" is the name of a field in the DESCR tag, but the contents go on the Info page, not on the main display. By default, Xymon wants to look up the host names in DNS (or at least using a resolver function), and thus they should be RFC-compliant.
