wrong values in RRD
by p3yeung＠gmail.com 22 Apr '13

22 Apr '13

I am using xymon 4.3.10. My xymon client sends 2 values to the xymon server, disk_free = 10404175872 disk_free_limit = 1000000000 The values displayed on the dashboard are correct. But xymon server stores a negative value for disk_free and zero for disk_free_limit. How can I make xymon stores the proper value to RRD? <ds> <name> diskfree </name> <type> DERIVE </type> <minimal_heartbeat> 600 </minimal_heartbeat> <min> NaN </min> <max> NaN </max>  <last_ds> 10404155392 </last_ds> <value> -6.7819016393e+04 </value> <unknown_sec> 0 </unknown_sec> </ds> <ds> <name> diskfreelimit </name> <type> DERIVE </type> <minimal_heartbeat> 600 </minimal_heartbeat> <min> NaN </min> <max> NaN </max>  <last_ds> 1000000000 </last_ds> <value> 0.0000000000e+00 </value> <unknown_sec> 0 </unknown_sec> </ds> Thanks P3

Xymon 4.3.11 released
by henrik＠hswn.dk 21 Apr '13

21 Apr '13

Hi, I have just released version 4.3.11 of Xymon. This release fixes a critical bug, which has caused crashes and other unwanted behaviour of the xymond daemon. Upgrading your Xymon server is recommended. Full list of changes: * Fix wrong file permissions when installing * Linux client: Fix handling of root filesystem when mounted on "/dev/root" * trends webpage: Fix case where hostname disappears after zoom. * FreeBSD client: Memory patch for FreeBSD 8.0+ * xymond_alert: Fix problem with UNMATCHED rules triggering when there are actual recipients, but their alerts are suppressed due to a REPEAT setting not having expired. * xymond_rrd: Dont crash if called with an empty status/data message * xymond_channel: Report cause when channel-child exits/crashes * xymongen: Geneate an overview page with only reds (like non-green) * xymongen: Optionally define env. variable BOARDFILTER to select hosts/tests included in the generated pages * links: Add pdf, docx and odt as known document formats * Fix potential crashes after an alert cookie expired * Fix potential crash after deleting/renaming a host * Speedup loading of the hosts.cfg file, noticeable with very large hosts.cfg files (100.000+ hosts) Currently only the source archive is available. Binary packages will show up in a couple of days. Regards, Henrik

snmp data question devmon/xymon
by tlewick＠apsaranetworks.com 19 Apr '13

19 Apr '13

This post could also go to devmon, but I've noticed the devmon mailing list is basically just about inactive. I set up devmon for multinode, so that its using mysql as a backend database. Everything appears to be working, but I thought it would also store the actual polled snmp data in the table test_data. All of the tables are being populated but that one. Does anyone know how to get devmon to store not just the config (templates, hosts/devices, thresholds, etc) but also the polled snmp data into the mysql database? Thanks, Taylor

Trunkated data from procs (OPEN)

An obvious solution for this might be to increase the global parameter MAXMSG_CLIENT, but will be valid for all clients. Another possible solution, but not wanted, might be to change the client behavior to local handling. A third solution could be to reduce the amount of data sent by the client.

custom hostnames problem
by deepakdeore2004＠gmail.com 19 Apr '13

19 Apr '13

I have xymon clients with the weird name, i tried adding CLIENT:name as mentioned in http://lists.xymon.com/oldarchive/2005/07/msg00362.html, but still the new name is not appearing. 10.x.x.x diff-host-name-app01.example.com # noconn nofiles nobbd NOCOLUMNS:files CLASS:STG CLIENT:app01-stg but the new hostname is not coming. I know we can use MACHINEDOTS but that i dont want because for ping test we use custom script which fails if hostname after 10.x.x.x is changes as per MACHINEDOTS variable.

Hi all, is there anyone that is using one script to check if root user is logged on Unix/Linux machines? Or is there anyone that is using "xymond_rootlogin.pl" and can explain me how to use it?

differentiating host types in analysis.cfg
by sholmes42＠mac.com 18 Apr '13

18 Apr '13

I want to be able to differentiate in analysis.cfg between debian servers and debian containers (not being a debian familiar I don't know what the non container version would be called). I looked at CLASS: in the hosts.cfg man page and it says that is used for log-file monitoring, however, in the analysis.cfg man page it talks about using CLASS= as a host selector. Will it work? I haven't tried it, but will be doing so unless someone here says not to. Specifically I want to check for PROC ntpd on regular debian servers and on redhat, but not check for it on debian containers since it can't run on them. Debian servers and redhat servers both report their class as linux so If I can override that on the containers and make it something else I think I can do what I want. Thanks for any insight.

Server side external scripts not working

The server has the hosts.cfg file, clients do not. It’s trying to access it. Without knowing what the script is doing, I can’t guess what’s happening. Don’t take the list out of your emails.
