Script launched but no column appears
by benjamin.boudoir＠eeple.fr 31 Aug '12

Hi, I've recently add a client perl script on some of my linux servers but the Xymon server does not add the column. The script seems to work correctly because I can see it data with bb- hostsvc.sh. I explicitly add the column name in bb-host but nothing's happen. Any ideas? Regards, -- Benjamin Boudoir meltyNetwork / Eeple Administrateur Système

Solaris 10 xymon SMF
by Paul.Root＠CenturyLink.com 29 Aug '12

29 Aug '12

One small problem. If you are stopping xymon in the global zone, you'll kill the iostat and vmstat of the NGZ machines as well. So a small changed pkill 'iostat|vmstat' -U xymon -z `zonename` Paul Root - Senior Engineer Managed Services Systems - CenturyLink From: Root, Paul Sent: Wednesday, August 29, 2012 8:59 AM To: 'Roland Soderstrom'; xymon at xymon.com Subject: RE: Solaris 10 xymon SMF The same thing happens in my Linux installs (and my Solaris installs). I generally do a: ps -ef |grep xymon |awk '{print $2}' |xargs kill. I think I like yours better. Paul Root - Senior Engineer Managed Services Systems - CenturyLink From: xymon-bounces at xymon.com<mailto:xymon-bounces at xymon.com> [mailto:xymon-bounces at xymon.com] On Behalf Of Roland Soderstrom Sent: Tuesday, August 28, 2012 4:48 PM To: xymon at xymon.com<mailto:xymon at xymon.com> Subject: [Xymon] Solaris 10 xymon SMF Hi, There is a minor issue with the Solaris 10 SMF for xymon by Galen Johnson that I improved a bit. Thanks Galen for the nice work :D At least it works fine for us. When you disable the xymon service it could wait for up to 5 min before disabling it because the iostat and vmstat are running. (300 min) I been trying some different approaches in the manifest but it doesn't really work properly. I had to change the default timeout (30) to 300 to cater for the 300min possible run time of iostat, vmstat. Otherwise it will go into maintenance mode. Today I had a different approach and changed the xymon.sh script instead, that worked really nice. In server/bin/xymon.sh I added these simple lines to the stop function. (works in Solaris 10) "stop") if test -s /usr/local/xymon/logs/xymonlaunch.pid then kill -TERM `cat /usr/local/xymon/logs/xymonlaunch.pid` echo "Xymon stopped" else echo "Xymon is not running" fi rm -f /usr/local/xymon/logs/xymonlaunch.pid # kill off the remaining xymon processes, ie vmstat iostat etc. sleep 2 pkill 'iostat|vmstat' -U xymon ;; Maybe it could help someone else out there. I'm running 4.3.10 - Roland

I'm currently running version 4.2.3 on a small (35 host) network, mostly Linux, with a few Mac OS X and one Windows host. What am I missing out on by not upgrading? I am not experiencing any problems (that I know about!) Richard Crane ------- Haskins Laboratories / (203) 865-6163 X 275 / FAX (203) 865-8963 300 George Street/New Haven, CT 06511

https intermediate certificate check
by bferrell＠baywinds.org 29 Aug '12

29 Aug '12

Hi all, I just did a quick search to see if xymon has a way to check intermediate certificates. The answer *seemed* to be "No, it's not possible... Then someone showed me curl (7.22) doing it... Well, at least it throws a descriptive message when a website with a "bad" intermediate cert is hit. Has anyone gotten this test to work or should I continue to work on a patch for this to submit? Inquiring minds want to know Bruce Ferrell

Issue with alerts and DISPLAYGROUP
by Patrick.Dubois＠bac-lac.gc.ca 29 Aug '12

29 Aug '12

Hi, I'm using version 4.3.10 of Xymon and I'm experiencing issues with the DISPLAYGROUP parameter in alerts.cfg. The following is working well: DISPLAYGROUP=Sharepoint COLOR=yellow TIME=W:0700:1700 MAIL sharepointadmins at hotmail.com<mailto:sharepointadmins at hotmail.com> REPEAT=365d but the following is not working (not generating alerts): DISPLAYGROUP=Sharepoint COLOR=yellow EXSERVICE=cpu TIME=W:0700:1700 MAIL sharepointadmins at hotmail.com<mailto:sharepointadmins at hotmail.com> REPEAT=365d If I try to specify a service with SERVICE instead of EXSERVICE, I get the same behavior. SERVICE and EXSERVICE work as expected in the following scenario (but of course I'm missing the group filtering): HOST=* COLOR=yellow EXSERVICE=cpu TIME=W:0700:1700 MAIL sharepointadmins at hotmail.com<mailto:sharepointadmins at hotmail.com> REPEAT=365d I think it's a bug, unless I missed something in the documentation.

OpenVPN Monitoring
by r.oliver＠web.de 29 Aug '12

29 Aug '12

Dear All, I have tried to find a way to Monitor my OpenVPN Servers. The hard thing was that OpenVPN is a service that is running via UDP by default. So here is the script I've come up with: ----------- #!/bin/sh BBHTAG=openvpn # What we put in bb-hosts to trigger this test COLUMN=$BBHTAG # Name of the column, often same as tag in bb-hosts OPENVPNPORT=1194 $BBHOME/bin/bbhostgrep $BBHTAG | while read L do set $L # To get one line of output from bbhostgrep HOSTIP="$1" MACHINEDOTS="$2" MACHINE=`echo $2 | $SED -e's/\./,/g'` COLOR=green MSG="$BBHTAG status for host $MACHINEDOTS" #... do the test, perhaps modify COLOR and MSG PROGCHECK=`which nc` if [ -z "$PROGCHECK" ]; then MSG="${MSG} `echo "Program \"nc\" not found."` " fi /bin/echo -ne "\x38\x01\x01\x01\x01\x01\x01\x01\x01\x00\x00\x00\x00\x00" | /bin/nc $MACHINEDOTS $OPENVPNPORT -u -w 1 | /usr/bin/hexdump -v -e '"\\""x" 1/1 "%02x" ""' | $GREP -q '\\x01\\x01\\x01\\x01\\x01\\x01\\x01\\x01\\x00\\x00\\x00\\x00' if [ "$?" != "0" ]; then COLOR=red MSG="${MSG} `echo "OpenVPN offline"` " else MSG="${MSG} `echo "OpenVPN online"` " fi $BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date` ${MSG} " done exit 0 ----------- Could someone try this out whether it works? Thanks in advance!

Hi all I'm running xymon 4.3.6 in prod and 4.3.9 in dev. I've just noticed that we're not seeing IO wait being graphed in dev. (Mix of RHEL4,5,6) Not sure if it matters but I'm using the RPMs from http://terabithia.org/rpms/xymon/testing/ Anyone else seeing this? Thanks CC -- RHCE#805007969328369

xymon.com and the mailinglists back online
by henrik＠hswn.dk 28 Aug '12

28 Aug '12

Hi, the xymon.com server had a minor disk "hiccup" last Saturday. Unfortunately, this triggered a kernel panic and things went pretty bad after that - eventually causing the whole server to die last Monday Aug. 20th. Unfortunately, I was 4000 km away - and even though I did manage to get an SSH session opened to the server, all attempts to reboot it remotely just gave me a "Bus error". My apologies for the inconvenience, it was a classic case of Murphy's Law that everything will go bad, at the worst possible time. I expect the mails submitted to the mailing list will show up over the next 24 hours or so, once the various mailservers retry their connection to xymon.com Regards, Henrik

Accessing Xymon from iPhone
by zandahar＠gmail.com 28 Aug '12

28 Aug '12

Hi All, I've had a bit of a search and didn't seem to turn up a lot otherwise slap me if I've missed something obvious. I've setup a new server on 4.3.10 after previously having a 4.3.0 I think beta release. Everything works ok but I cannot access the menus from an iPhone whereas I could previously ? It works fine from a PC browser. Has the menu changed to be rendered in something not iOS friendly ? Cheers Allan

Xymon Graphs
by adam＠websitemanagers.com.au 28 Aug '12

Hi, I've written a quick addon to collect the temperature of each HDD in my system, and report the data back to Xymon like this: Fri Aug 24 02:33:11 EST 2012 Temp GOOD (27 degrees) sda : 27 sdb : 27 Also, hobbit is putting this data in to an RRD file called temp.rrd: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE rrd SYSTEM"http://oss.oetiker.ch/rrdtool/rrdtool.dtd">  <rrd> <version>0003</version> <step>300</step>  <lastupdate>1345738019</lastupdate>  <ds> <name> sda </name> <type> GAUGE </type> <minimal_heartbeat>600</minimal_heartbeat> <min>NaN</min> <max>NaN</max>  <last_ds>37</last_ds> <value>4.4030000000e+03</value> <unknown_sec> 0 </unknown_sec> </ds> <ds> <name> sdb </name> <type> GAUGE </type> <minimal_heartbeat>600</minimal_heartbeat> <min>NaN</min> <max>NaN</max>  <last_ds>39</last_ds> <value>4.6410000000e+03</value> <unknown_sec> 0 </unknown_sec> </ds> So it looks (to me) as though all that is working. I'm now trying to get the pretty graph to show up, here is my current definition which doesn't work: [temp] TITLE HDD Temperature YAXIS Degrees DEF:hda=temp.rrd:hda:AVERAGE DEF:hdb=temp.rrd:hdb:AVERAGE DEF:hdc=temp.rrd:hdc:AVERAGE DEF:hdd=temp.rrd:hdd:AVERAGE DEF:hde=temp.rrd:hde:AVERAGE DEF:sda=temp.rrd:sda:AVERAGE DEF:sdb=temp.rrd:sdb:AVERAGE DEF:sdc=temp.rrd:sdc:AVERAGE DEF:sdd=temp.rrd:sdd:AVERAGE DEF:sde=temp.rrd:sde:AVERAGE LINE2:hda#FF0000:hda LINE2:hdb#0000FF:hdb LINE2:hdc#00FF00:hdc LINE2:hdd#FFFF00:hdd LINE2:hde#FF00FF:hde COMMENT:\n GPRINT:hda:LAST:hda \: %5.1lf%s (cur) GPRINT:hda:MAX: \: %5.1lf%s (max) GPRINT:hda:MIN: \: %5.1lf%s (min) GPRINT:hda:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hdb:LAST:hdb \: %5.1lf%s (cur) GPRINT:hdb:MAX: \: %5.1lf%s (max) GPRINT:hdb:MIN: \: %5.1lf%s (min) GPRINT:hdb:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hdc:LAST:hdc \: %5.1lf%s (cur) GPRINT:hdc:MAX: \: %5.1lf%s (max) GPRINT:hdc:MIN: \: %5.1lf%s (min) GPRINT:hdc:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hdd:LAST:hdd \: %5.1lf%s (cur) GPRINT:hdd:MAX: \: %5.1lf%s (max) GPRINT:hdd:MIN: \: %5.1lf%s (min) GPRINT:hdd:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hde:LAST:hde \: %5.1lf%s (cur) GPRINT:hde:MAX: \: %5.1lf%s (max) GPRINT:hde:MIN: \: %5.1lf%s (min) GPRINT:hde:AVERAGE: \: %5.1lf%s (avg)\n I think the problem is that not every machine will have the same number of disks, nor will they have the same type of disk. Can anyone suggest how to re-write this so that it will work? Thanks, Adam
