CONFIGCLASS change not getting picked up
by larry＠fni-stl.com 11 Dec '15

11 Dec '15

Not a major deal but as we are updating systems and changing OS versions (e.g. CONFIGCLASS=rhel6 changed to CONFIGCLASS=rhel7) the new setting is not getting read by the xymon server until I do a full restart of the xymon service. "service xymon-server reload" did not work. Also restarted remote side (hobbit in this case), dropped the client, added it back. Server kept using the old CONFIGCLASS setting even though the data coming through had the new value as shown in clientlog. [collector:] client xxxxx.linux rhel7 Anyone run into this before? v4.3.21 RHEL 6.7 ========================================================= Larry D.

xymonnet yellow alarm
by fclaire＠free.fr 11 Dec '15

11 Dec '15

Hi, Is there a way to configure the number of seconds where xymonnet will start to do a yellow alarm ? I can't find anything... I remember it was doing yellow alarms only if time to execute all tests is greater than 300 seconds. It seems it's now 20 seconds on my xymon server 4.3.21-4.el7.terabithia. Any hint is welcome. Cheers, Francois.

Patch for xymonnet: Fails to detect closed ports on SSL-enabled services
by henrik＠hswn.dk 11 Dec '15

11 Dec '15

Hi, I ran into a weird issue this morning. When testing an SSL-enabled service (amqps), the status showed up as green even though there was no service listening on the port. It may be related to the fairly old OpenSSL version installed (0.9.8j + SUSE patches), because I have never seen it before - and it sounds like the kind of bug that ought to pop up fairly quickly. Debug shows: 38969 2015-12-11 12:02:01.466947 TCP tests completed normally Address=10.0.0.1:5671, open=1, res=0, err=5, connecttime=0.001542, totaltime=0.001542, 38969 2015-12-11 12:02:01.467163 Sending results for service amqps 38969 2015-12-11 12:02:01.467205 Adding to combo msg: status+30 foo,example,com.amqps green  Fri Dec 11 12:02:01 2015 amqps ok The "open=1" is what triggers the green status, but it doesn't match the "err=5" which means the openssl-functions returned an error. This patch should fix it - against 4.3.24. Regards, Henrik

how to get list of IP addresses used by Xymon for each host entry
by Andy.Farrior＠victoriacollege.edu 11 Dec '15

11 Dec '15

if your hosts.cfg file looks like this: 0.0.0.0 foo # dns 10.1.1.2 bar # testip ntp and the DNS lookup for foo is 10.1.1.1, what xymon command would I issue in a script to get a list of the IP addresses Xymon has associated with each host? so, for the above example, the result would be: 10.1.1.1 foo # tests 10.1.1.2 bar # tests I'm looking for a way to get the IP addresses Xymon is using for each host. thx, andy

SCRIPT running twice
by ampinder.singh＠hotmail.com 10 Dec '15

10 Dec '15

Hello, I'm having an issue here. I want to run an external script in Xymon. So i follow the docs. I'm trying to run a test script that will for now just to an echo to a logfile. Here is what I have done. * In analysis.cfg HOST=qcdvap1096 LOG /home/xymon/client4.3.17/logfile "testword" * In client-local.cfg [qcdvap1096] log:/home/xymon/client4.3.17/logfile:2048 trigger error #The logfile is on the client * In alerts.cfg HOST=qcdvap1096 SERVICE=msgs COLOR=red,purple #MAIL ampinder.singh at cgi.com COLOR=red REPEAT=2h #SCRIPT /home/xymon/server/scripts/connect.sh MAIL ampinder.singh at cgi.com COLOR=red SCRIPT /home/xymon/server/scripts/connect.sh MAIL ampinder.singh at cgi.com COLOR=red I have created my test script on the server: #Name of the script: connect.sh #!/bin/bash #This script on the server where Xymon is installed will call another script ont the client (qcdvap1096) ssh xymon at 142.101.131.45 /home/xymon/client4.3.17/ext/test.sh This is my script on the client (qcdvap1096) that gets called #!/bin/bash #Name of the script: test.sh #Working line #echo "it's down again" >> /home/xymon/client4.3.17/loggenerated.txt echo "`date` "Server" "went" "out"" >> /home/xymon/client4.3.17/ampinder.txt So I manually add the word "testword" on logfile and it works my script gets called. But my only issue is that the script gets run twice. Like a second of eachother Here is the output of the log generated (/home/xymon/client4.3.17/loggenerated.tx) Thu Dec 10 13:12:55 EST 2015 Server went out Thu Dec 10 13:12:56 EST 2015 Server went out I dont know why it runs twice. I only want it to run once. As soon, it's see the word "testword" it should run it once. Could you please help me resolve this issue? Thanks Ajay

Xymon + graphite
by Galen.Johnson＠sas.com 10 Dec '15

10 Dec '15

Hey, Has anyone tried to integrate alerting based on Graphite? Or used Graphite as a trending replacement to rrd? I love Xymon for my monitoring but the limitations and aggregations of rrds are starting to become an issue. thanks =G= NB: I was sent this link today, http://blog.takipi.com/graphite-vs-grafana-build-the-best-monitoring-archit…, and on the Graphite page there is this link under monitoring that I thought I might consider modifying for Xymon: https://github.com/blacked/graphite-to-zabbix. =G=

Segfault in confreport-critical.sh / confreport.cgi in 4.3.24
by beckert＠phys.ethz.ch 10 Dec '15

10 Dec '15

Hi, Via corekeeper (https://packages.debian.org/stable/corekeeper) I became aware of a segfault of confreport.cgi. I'm able to reproduce it (at least) in a fresh browser instance (all cookies removed), going to "Find host", searching for a non-existing host and then clicking on "Config Report (Critical)". It says "172 hosts included" (i.e. not just a single host as it happens if I searched for an existing host before) and then outputs most of the page, but ends in the middle of the alerts listing at line 8049 in the middle of a table: <tr><td><font COLOR="#000000" FACE="Tahoma, Arial, Helvetica">079xxxxxxx at example.com (R)</font></td><td align=center>5m 1s </td><td align=center>-</td><td align=center>4h </td><td align=center>-</td><td>purple</td></tr> <tr><td valign=top rowspan=4 >ports</td><td><font COLOR="#000000" FACE="Tahoma, Arial, Helvetica">0765 At least in one of the cases it ended in the same line, but with "076 instead of 0765". So I suspect we hit some C string size limit once again. I don't have a proper backtrace (yet), but I had look at the source code and I'm quite confident that the issue is inside the function print_alert_recipients() starting at lib/loadalerts.c, line 1124. I suspect it's an overflow of the variable "buf". "l" seems large enough with 4kB.

issues with new install
by jlaidman＠rebel-it.com.au 10 Dec '15

Michael, have you checked your ghost report? Perhaps the hostnames in hosts.cfg don't match what the clients know themselves as.

Custom addon - missing client data
by neilsimmonds1808＠gmail.com 09 Dec '15

09 Dec '15

Hi Blake, I’m also trying to implement this and as far as I can see the “clear” column is correct for this test (There’s a part of the script that sets the colour to clear) but I have a problem with no graphs showing which seems to be because the rrd data is not present in the xymon/data/rrd/clientname/ directory. Did you manage to get it working? Regards, Neil. *From:* Xymon [mailto:xymon-bounces at xymon.com] *On Behalf Of *Blake *Sent:* 03 September 2015 22:20 *To:* xymon at xymon.com *Subject:* [Xymon] Custom addon - missing client data I am trying to implement "xymon-mysql-counters" by ZeWaren which I found on github https://github.com/ZeWaren/xymon-mysql-counters. I have followed the directions adding "xymon_mysql_counters.pl" to the ext directory of clients and updated the mysql login information. I have verified that the appropriate user account is able to execute the script with 755 permissions and manual execution of the script works. Updates to clientlaunch.cfg have been configured as well. The client was restarted after this work was completed. On the server I have updated graphs.cfg on the server under etc/ appending graphs.cfg from github to the end of the file. Server side a mysql column is now present, however only a "no data" icon is present. Reviewing the returned client data shows there is no "[mysql]" section. My setup is a pull configuration using memcache. Thanks in advance for all help to get this working.
