Problem with MAXMSG_DATA, possible bug?
by betsy.schwartz＠gmail.com 19 May '11

19 May '11

I'm having trouble with a server not reporting procs, and I'm seeing this error in hobbitd.log: 2011-05-18 22:46:55 Oversize data/client msg from 10.100.32.150 truncated (n=877375, limit 524288) Now, I've played around with MAXMSG_DATA and MAXMSG_CLIENT, always restarting xymond, but I cannot get that limit above 524288. If I set very low values, I get a lower limit, but I can't seem to set higher values and get a *higher* limit. Right now I've got MAXLINE="1572864" MAXMSG_STATUS="4096" MAXMSG_DATA="4096" Am I missing some dependency? (this is xymon 4.3.2 on Oracle Linux) thanks Betsy

Elegant way to run an aggregate ext test over multiple clients?
by betsy.schwartz＠gmail.com 18 May '11

18 May '11

Suppose I have a five-server cluster, and on each server there's a calculated value, call it Q, and an ext test "qlength" that operates on Q and returns a color and a message containing Q. We want to make a server-side test that does some alerting based on aggregate values of Q across all five servers in the cluster. Not a combo test, we want to do math, like Sum (Q1...Qn) >Threshold. *One* way to get Q for each server is to write a server-side ext test that loops a wget over each host, something like: wget /dev/null http://xymon/xymon-cgi/svcstatus.sh\?HOST=myhost.example.com\&SERVICE=qleng… then parse each server's Q info out of the html and do my arithmetic, but is there a more direct way? thanks for any pointers clues or code snippets Betsy

Chris has updated his wonderful script that was written for hobbit ############################## # bb-hosts.cgi # Written by: Chris Naude # Purpose: Provides a basic web interface to edit bb-hosts. # Uses a lock file and md5sums to keep things sane. # Requirements: md5sum # File permissions should be setup so that the web user can write to $xymon_hosts_file # Hint: Use chmod, chown, setfacl, or sudo. ;) # Tested on Red Hat AS 3 with Apache2 # # Version 1.3 - Left justify textarea for IE # - Fixed menu # Version 1.2 - Now supports Xymon 4.3.2 and greater. # Version 1.1 - Added Xymon support. Enjoy! # ############################## go take a look and check out his script section from the menu to view the source https://cnaude.mdns.org/xymon2-cgi/bb-hosts.cgi Thanks Chris our enviroment uses this alot for multiple pages.

Kiosk mode?

Is there some type of kiosk type interface that would be presented to external customers to show our systems availability? (IE, they don't have the menu bar at the top, the system nodes are not clickable, etc...)

Apache2 lib path in Solaris 10
by rolands＠logicaltech.com.au 18 May '11

18 May '11

Hi, I'm running latest 4.3.3 on Solaris 10 sparc. What is the best way of making Apache2 in solaris 10 to find /usr/local/lib (needed for libpcre.so.0 for once) I must use the built in apache2. 1 setting LD_LIBRARY_PATH for apache2 somewhere, can't find a suitable solution there. 2 crle -u -l /usr/local/lib Don't fancy that as it is GLOBAL. but the only solution I have right now. 3 setting some VAR in Apache2 conf somewhere so Apache2 find /usr/local/lib I don't fancy any "hacks" that could break apache2 any time I apply a Solaris apache2 patch. A solid Production solution is preferred. Any ideas, pros and cons appreciated. - Roland

Issues/confusion with 4.3.3
by jbhuber＠judahnet.net 18 May '11

18 May '11

Hi folks, Have been using BigBrother, then Hobbit, now Xymon for many years. I recently built a new machine and did a clean install/build of xymon 4.3.3 and am having some issues/confusion I hope the list can help me with. My first major issue is with the "clamd" service check, this worked fine under Fedora-13 and Xymon-4.2.3, however (new O/S is RHEL 6.0 Workstation) with Xymon 4.3.3 all it does is fail saying: "Service unavailable (Connection refused)".... I can telnet to port 3310, type "PING" and it comes back with "PONG" which is what the protocols.cfg says...I have tried turning off "banner", no help....I am doubtless missing something simple... FYI, all the other service check I use work fine (IE: DNS, IMAP, NTP, SMTP)....WHat am I missing ? Regards, and TIA, Jim --

Alert configuration
by akshar.bhosale＠gmail.com 17 May '11

17 May '11

Hi, we have xymon4.2.2 and we want to have alert configuration simplified. We don't want to actually edit the hobbit-alerts.conf file for every small change. We want to have some UI based tool for that. hobbittools does not provide this functionality. How we can change the alerts configuration without touching the file.

Monitor Salesforce?
by Jason.Chambers＠geosoft.com 17 May '11

Does anyone know how we could implement a monitor for the Salesforce status site? It's here http://trust.salesforce.com/status-data/status.jsp but I was wondering if there was a way to make sure a checkmark existed in the Current Status column for NA1 for example.
