log monitoring hostname matching trouble
by EDSchminke＠Hormel.com 14 Jan '16

Hi Jeremy, Thanks for your reply. First, I am aware of the 10 minute interval. I did observe that when working with an AIX system. I mention that because I am able to get log monitoring to work there, but not with a Linux system. That is to say, I do get a "logfetch.[hostname].cfg" file in $XYMONHOME/tmp, and changes come in approx ten minutes after being made on the XYMON server at $XYMONHOME/etc/client-local.cfg Is there anything I can do to reduce the 10 minute interval for testing purposes? ----- Entering "xymoncmd" [root at lpcobwas2p ~]# su - xymon -bash-4.1$ export XYMONCLIENTHOME=/home/xymon/client -bash-4.1$ client/bin/xymoncmd sh-4.1$ whoami xymon sh-4.1$ pwd /home/xymon sh-4.1$ ---- All files in /home/xymon are owned by xymon, group xymon and are writable sh-4.1$ find . ! -writable sh-4.1$ find . ! -user xymon sh-4.1$ find . ! -group xymon sh-4.1$ $XYMONTMP/msg.$(hostname).txt is getting updated every five minutes, as expected: sh-4.1$ ls -la client/tmp/msg.$(hostname).txt -rw-rw-r--. 1 xymon xymon 152566 Jan 13 08:00 client/tmp/msg.lpcobwas2p.hfc.ad.txt sh-4.1$ ls -la client/tmp/msg.$(hostname).txt -rw-rw-r--. 1 xymon xymon 148917 Jan 13 08:05 client/tmp/msg.lpcobwas2p.hfc.ad.txt sh-4.1$ ----- I sent this file manually to the xymon server, but got no output sh-4.1$ $XYMON $XYMSRV "@" < $XYMONTMP/msg.lpcobwas2p.hfc.ad.txt sh-4.1$ ----- Sending your suggested test string yields the following: sh-4.1$ $XYMON $XYMSRV "@" << EOT client $MACHINE.linux linux EOT log:/var/log/messages:10240 ignore MARK sh-4.1$ echo $MACHINE lpcobwas2p,hfc,ad sh-4.1$ Interesting... but a) why doesn't that come back with the message file and b) it still doesn't match the hostname ----- Lastly.. I'm still not clear on the correct format of a hostname definition for client/etc/client-local.cfg Should it be lpcobwas2p (just hostname) lpcobwas2p.hfc.ad (period) lpcobwas2p,hfc,ad (commas) Thanks, Erik D.

It's hard to know what might be wrong. First, note that it can take some time (10 minutes maybe) for the cfg file to appear. Check your ~xymon/client/tmp/ directory and ensure that the xymon user can write there (probably should have owner and group both as "xymon"). Then, see if you have a client message temp file there with something like ls -l ~xymon/client/tmp/msg.*.txt This should show the hostname that the Xymon client is using, as part of the filename. It will also show the permissions, which should make the file writeable by the xymon user. Also, check the first line of the file (eg: head -1 ~xymon/client/tmp/msg.*.txt) and see if the hostname listed there is what you're expecting. Try sending the msg.*.txt file via the xymon client message, and see if you get the cfg file as output: $ ~xymon/client/bin/xymoncmd $ $XYMON $XYMSRV @ < $XYMONTMP/msg.*.txt $ exit Or even just: $ ~xymon/client/bin/xymoncmd $ echo "client $MACHINE.linux linux" | $XYMON $XYMSRV @ (Substitute "linux" for your OS.)

where does xymon client get tcp packet data?
by john.thurston＠alaska.gov 14 Jan '16

14 Jan '16

The below relates to linux, xymon 4.3.17 I was going to write a script to collect and report numbers of TCP packet retransmissions. But when I look at the 'trends' for this host, I see there is already a chart for "TCP/IP statistics" which includes "In/Out/Retrans" I'm specifically looking for TCP retransmission count. This counter does not seem to line up with information being reported by nstat. What is this built-in test reporting, and from where is it collected? -- Do things because you should, not just because you can.

Temperature plugin for xymon

Some time ago I had found the lm_sensors project. There were some instructions for many hardware. Sorry to say, but right now the web-site http://lm-sensors.org/ have no more content about this. However the lm-sensors was included in many Linux distributions (at least on CentOS, RHEL 6.x and similar), so it was possible to: # install yum install lm_sensors # run to detect devices sensors-detect # and if OK (it has drivers for your hardware) then can get the output: sensors acpitz-virtual-0 Adapter: Virtual device temp1: +8.3 C (crit = +31.3 C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +57.0 C (high = +78.0 C, crit = +88.0 C) Core 0: +54.0 C (high = +78.0 C, crit = +88.0 C) Core 1: +52.0 C (high = +78.0 C, crit = +88.0 C) Core 2: +51.0 C (high = +78.0 C, crit = +88.0 C) Core 3: +54.0 C (high = +78.0 C, crit = +88.0 C) power_meter-acpi-0 Adapter: ACPI interface power1: 0.00 nW (interval = 300.00 s) coretemp-isa-0004 Adapter: ISA adapter Physical id 1: +50.0 C (high = +78.0 C, crit = +88.0 C) Core 0: +50.0 C (high = +78.0 C, crit = +88.0 C) Core 1: +49.0 C (high = +78.0 C, crit = +88.0 C) Core 2: +45.0 C (high = +78.0 C, crit = +88.0 C) Core 3: +49.0 C (high = +78.0 C, crit = +88.0 C) Detailed information is available at: https://www.kernel.org/doc/Documentation/thermal/ Please, drop me a mail if You will find anything useful.

How many times does xymonnet retry?
by glauber.ribeiro＠experian.com 13 Jan '16

13 Jan '16

Hello, all, I didn’t find this information in the man pages for xymonnet and xymonnet-again. How many times does xymonnet retry a failed test? Does it go red on the first failure (assuming default configuration), or only after all the retries failed? Thanks, glauber

Alerts
by john＠executech.com 11 Jan '16

11 Jan '16

I am getting strange behavior that I can't solve. I have specific users monitoring a subpage of servers. When I move a set of servers from one user (subpage) to another user (a different subpage), the new user is getting the alerts but the alerts are also going to previous user as well. One thing that helped in the past was to delete any data related to the set of servers in the subpage folder inside www. But recently that hasn't helped. Alerts are based on the page so that all subpages under them will alert them by default: PAGE=%.*UserPage/ SCRIPT=/custom-alerts/alert.sh user at domain.com RECOVERED REPEAT=720 DURATION>10 If I check the info page of any of the servers, the new user is listed but nothing is listed for the old user. Has anyone seen this before? John Tullis

Couple of questions on client data
by davieb＠gmail.com 11 Jan '16

11 Jan '16

I see that there is data in the client data that is not turned into columns? Can I turn this data into columns to report? I'm using xymon 4.3.20 on both the client/server. On linux, I see that this data is not turned into any columns: [who] [route] [netstat] [ifstat] Not that I'd use all of them, just wondering what the reasoning is behind it. Also, I notice that getting the data via xymondboard is not 100% either... [xymon at ztest bin]$ ./xymon 192.168.1.230 "clientlog yumlist section=who" [who] davieb tty1 May 11 21:01 (:0) davieb pts/1 May 11 21:02 (:0.0) davieb pts/2 May 11 21:40 (:0.0) As you can see below, requesting a status on all the tests, there is no "who" being reported. But just a moment ago, asking for just that data it works.

Merging hosts
by thomleavitt＠gmail.com 09 Jan '16

09 Jan '16

Is there an easy (or even medium hard) way to merge the content of two hosts? I updated the entry for a server in Xymon to a fully qualified hostname, but the server is identifying itself with an unqualified hostname, and putting the CLIENT: tag fixed it, but for some reason, it seems to have lost track of the prior history. :/ Regards, Thomas Leavitt

vpage
by Galen.Johnson＠sas.com 08 Jan '16

08 Jan '16

Hey, I have a few pages that have lots of tests but few servers so I wanted to see if vpage would work for me. It did what I wanted except it has an all or nothing aspect to it. Ideally, vpage would let me keep my organizational structure (including the group headers) and only switch the tests to the rows. Or am I missing something? I read the man page and tried several different setups but couldn't make it work the way I'd hoped. Anyone else managed to get Xymon rendering to work this way? thanks =G=
