RRD Graph question - dynamic fields
by campbell_sjc＠hotmail.com 23 Mar '16

23 Mar '16

Hi I am using xymon/rrd to graph the number of events / subevents persisted to a database on a daily basis. This is to gather trending and also for monitoring. I am trying to graph the number of 'subevents'.The problem I am facing is that not all subevents show up each day and therefore I receive this error,...is there a way I can get the rrd to ignore the definition if it is not present in the rrd file or do i have to stub each subevent to '0' until an event occurs for it ?"No DS called 'REQUEST AUTHORIZED' in 'ACCESS_EVENTS.rrd'" Thank you for any guidance here. SJC

Advanced HTML Mail Alert Perl script
by A.Chervonets＠cominder.eu 23 Mar '16

23 Mar '16

I have tested it on xymon 4.3.17 - working good, but some notes: It generated at mail body start the link like: See http://hostname/xymon-cgi/bb-hostsvc.sh?HOST=target_host&SERVICE=disk But there is no bb-hostsvc.sh on server. But instead we have svcstatus.sh . Whether it was changes to bb-hostsvc.sh in latest xymon versions? Or perl sript version on xymonton is just fork of addon for older versions ?

postfix monitoring plugin from xymonton -- graphs not working
by hobbit＠elyograg.org 23 Mar '16

23 Mar '16

I am using this plugin: https://wiki.xymonton.org/doku.php/monitors:postfix It works well, except the graphing. I made the suggested edits to the xymon config. I assume that either I screwed something up or the docs are out of date. What can I do to get the graphs working? If info is needed to pinpoint the problem, please let me know and I will send it. Thanks, Shawn

"ports" RRD graph is often flaky.
by hobbit＠elyograg.org 23 Mar '16

23 Mar '16

I see several graphs like this in xymon (4.3.23), where at least one of the port graphs (configured in analysis.cfg) has lots of data points missing: https://www.dropbox.com/s/l483lilzh5n610k/flaky-xymon-port-graph.png?dl=0 Any idea how I can fix this? As you can see, the red line for http has data for the entire graph, while the blue line for ajp is very spotty. I just added the last two monitors less than an hour ago, so I don't have history on those yet. This is not unique to this host. As far as I can tell, the port listings coming back from the client are always good, even when the graph has no line. Thanks, Shawn

Custom non-ncv graph
by tomas.wachtarczyk＠gmail.com 23 Mar '16

23 Mar '16

Hello, I am struggling with displaying custom graph. It should display volumegroups on host with VGSIZE, VGFREE and VGPRCT (usage of VG) Number of VG are not constant, it may differ. So i am sending it as data and i can find rrd on xymon server. TEST=*VG* BBVGB=$(sudo /usr/sbin/vgs --units B --nosuffix --noheadings --aligned --o vg_name,vg_size,vg_free) while read VG VGSIZE VGFREE; do VGPRCT=$(bc <<< "scale=2;100-(${VGFREE}/${VGSIZE}*100)") DATA="${DATA} [*VG2*,${VG}.rrd] DS:vgsize:GAUGE:600:0:U ${VGSIZE} DS:vgfree:GAUGE:600:0:U ${VGFREE} DS:vgprct:GAUGE:600:0:100 ${VGPRCT} " done <<< "${BBVGB}" It produce [*VG2*,appvg.rrd] DS:vgsize:GAUGE:600:0:U 314572800000 DS:vgfree:GAUGE:600:0:U 69130518528 DS:vgprct:GAUGE:600:0:100 75 [*VG2*,rootvg.rrd] DS:vgsize:GAUGE:600:0:U 2472800000 DS:vgfree:GAUGE:600:0:U 430518528 DS:vgprct:GAUGE:600:0:100 97 Sending it to xymon server with ${XYMON} ${XYMSRV} "data ${MACHINE}.trends ${DATA}" Data are delivered, i can dump rrd on xymonserver, seems to ok to me, archive is filling up, but i am not able to display it on trends or GRAPH_ *VG*="*VG2*" page. rrdttol dump *VG2*,appvg.rrd <ds> <name> vgsize </name> <type> GAUGE </type> <minimal_heartbeat> 600 </minimal_heartbeat> <min> 0.0000000000e+00 </min> <max> NaN </max>  <last_ds> 314572800000 </last_ds> <value> 2.6109542400e+13 </value> <unknown_sec> 0 </unknown_sec> </ds> I set it in xymonserver.cfg to TEST2RRD="....VG2" (is it correct?) and GRAPHS="...VG2" I tried to define it also in graphs.cfg [*VG2*] FNPATTERN VG2.(.+).rrd TITLE Volume group DEF:vgsize=@RRDFN@:vgsize:AVERAGE DEF:vgfree=@RRDFN@:vgfree:AVERAGE DEF:vgprct=@RRDFN@:vgprct:AVERAGE LINE1.5:p at RRDIDX@#@COLOR@:@RRDPARAM@ GPRINT:vgsize:LAST: \: %5.1lf (cur) GPRINT:vgsize:MAX: \: %5.1lf (max) GPRINT:vgsize:MIN: \: %5.1lf (min) GPRINT:vgsize:AVERAGE: \: %5.1lf (avg)\n GPRINT:vgfree:LAST: \: %5.1lf (cur) GPRINT:vgfree:MAX: \: %5.1lf (max) GPRINT:vgfree:MIN: \: %5.1lf (min) GPRINT:vgfree:AVERAGE: \: %5.1lf (avg)\n GPRINT:vgprct:LAST: \: %5.1lf (cur) GPRINT:vgprct:MAX: \: %5.1lf (max) GPRINT:vgprct:MIN: \: %5.1lf (min) GPRINT:vgprct:AVERAGE: \: %5.1lf (avg)\n I was able to understand when i was sending ncv only vg:percentage appvg:75 rootvg:98 , and it worked. But i am stupid for more complex solutions and lost in english. I am sure it is very easy task, but i just do not get it. Thank you for your help W. P.S: I have plan to send VG as status with human formated output and VG2 will be data for graphs.

NTLM Authentication
by thomleavitt＠gmail.com 22 Mar '16

22 Mar '16

I have a web app (trac) that back ends to Active Directory via NTLM, and would like to test that the actual login functionality is working... has anyone done this? I found a script that does NTLM to a proxy for external connectivity checks, and figured out that curl can do NTLM, so I have "curl", on it's own, able to successfully authenticate (using a privilege stripped account). Question: is the authentication to the web app done in the clear when the URL is of the form http:// as below... the Windows guys state that Two: does anyone have a pre-written script? I'm planning to integrate the following command, and adapt the referenced script... which I guess would function as an external plugin, so to speak. curl --ntlm -u 'DOMAIN\account:password' -s -S -L -I http://host.example.com/trac/login -m 30 -w 'Seconds: %{time_total}\n' Note: script hasn't yet been adapted #!/bin/sh TESTHOST=www.google.com<http://www.google.com> TESTURL=http://$TESTHOST/ <http://%24testhost/>TIMEOUT=30 # Grab *just* the headers, simulating Xymon's builtin http check MESSAGE=`curl -x http://ourproxy.ourdomain.com:8080 \ --proxy-anyauth -U hobbituser:hobbitpassword \ -m $TIMEOUT \ -w 'Seconds: %{time_total}\n' \ -s -S -L -I $TESTURL | $GREP -v Set-Cookie` if [ "$?" -eq "0" ]; then COLOR=green else COLOR=red fi # convert dots to commas in the hostname MACHINE=`echo $TESTHOST | $SED -e 's/\./\,/g' $BB $BBDISP "status $MACHINE.home $COLOR `date` $MESSAGE" If someone else has already done that, great. Thomas P.S. the alternative to NTLM is connecting via LDAP to AD servers that don't have LDAPS enabled (yet), which I'd rather not do.

On our xymon (4.3.26) server, which otherwise works just fine, /var/log/xymon/xymonlaunch.log issues the following warning the following every 5 minutes. This again indicates that the culprit is xymonlaunch : WARNING: Cannot open include file '/var/run/xymonclient-runtime.cfg', line was: include /var/run/xymonclient-runtime.cfg This seems related to an earlier report @ http://comments.gmane.org/gmane.comp.monitoring.hobbit/26155 stating " that in: /usr/lib/xymon/client/etc/xymonclient.cfg on the server once the RPM is installed you need to replace the include statement with the below text: XYMSRV="" # IP address of the Xymon server XYMSERVERS="" # IP of multiple Xymon servers. XYMSRV must be "0.0.0.0". This is because the init script for the client correctly uses the /etc/default/xymon-client to create a file /var/run/xymonclient-runtime.cfg that is what is included, but the server init script does not do these things." I suppose there are multiple ways to resolve this, but some advice is needed: 1) include a few line into the server init script (/etc/init.d/xymon) which creates the xymonclients-runtime.cfg file 2) modify or remove the include line in /usr/lib/xymon/client/etc/xymonclient.cfg on the server We use rpms created from the supplied spec files, and the server has the xymon package installed only, as the xymon(-server) and xymon-client packages conflicts (you can not install both) For now we have commented the include line out manually, but please advise on what a proper resolution might look like. regards ...torkil...

Advanced HTML Mail Alert Perl script
by helge.jacobsen＠atos.net 21 Mar '16

21 Mar '16

Hi all, there is an old html_mail.pl script on https://wiki.xymonton.org/doku.php/alerts:html_mail1.2 . I like it, but I miss some features. So I take this script and make some updates and modifications: Different Mail Subject depending on Errorlevel Duration Time for any Message Flapping Status included in Subject and Mailtext Colorstatus depends on BBALPHAMSG for Recover Status. Nesessary if you using yellow for OKCOLOR Add Enable/Disable Mail Subject / Removing Backgroundcolor: not accessible in Outlook and makes mails in Thunderbird unreadable Fix for disable "until okay": Convert XYmon Recover Bodytext "for -1 minutes" to "until okay" maybe it is useful for someone here in the community but nobody knows it ? It is running on Xymon 4.3.26 and tested with Outlook 2010 and Thunderbird 38.6.0 And you found it here: https://wiki.xymonton.org/doku.php/alerts:html_mail2.0 regards Helge
