Too much data for svcstatus.sh?
by mburger＠bubbanfriends.org 12 Oct '20

12 Oct '20

Good morning. Running Xymon 4.3.30, compiled from source tarball, on a RHEL 6.10 server. This morning, I encountered an interesting issue. I have a monitored system that has 197 discrete filesystems/mounts. When I attempt to enter this server's "Trends" section, I receive an internal server error (500). My httpd error log shows this when I attempt to access the trends link for the server in question: [Thu May 21 11:29:41 2020] [error] [client 10.40.24.55] Premature end of script headers: svcstatus.sh, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] *** glibc detected *** /apps/xymon/server/bin/svcstatus.cgi: realloc(): invalid next size: 0x0000000000de7dd0 ***, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x408a4f], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x403453], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x404bb7], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] /apps/xymon/server/bin/svcstatus.cgi[0x4022c9], referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] 00400000-0043c000 r-xp 00000000 fd:08 24906 /apps/xymon/server/bin/svcstatus.cgi, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html [Thu May 21 11:29:59 2020] [error] [client 10.40.24.55] 0063c000-0063e000 rw-p 0003c000 fd:08 24906 /apps/xymon/server/bin/svcstatus.cgi, referer: http://sysmon.fhmc.local/xymon/edmprod/edmprod.html This does not happen for any other monitored system in my environment. This system is one of the more critical servers in my environment, so I'd like to figure out what's going on and remediate it if possible. -- Mike Burger http://www.bubbanfriends.org "It's always suicide-mission this, save-the-planet that.

"noconn" configuration feature oddity ...
by jeremy＠laidman.org 06 Oct '20

Ian An interesting discovery indeed. Although I'm not greatly surprised. A host that has no tests and has never had any test results, is not a particularly interesting one, and is rather like a tree falling in an uninhabited forest, where nobody knows - or even cares - about the state of the tree. I'd attribute this phenomenon to the type of "undefined behaviour" that can occur when any process is asked to do something it wasn't designed to do and which, in essence, makes no sense. Unless I'm missing something.

"noconn" configuration feature oddity ...
by didds3＠yahoo.co.uk 05 Oct '20

A colleague and I noticed a feature of xymon last week, and tested it across a few version from 4.3.12 to 4.3.17?? [ upgrading etc etc is not a trivial matter in these environments so its meaningless to just suggest "upgrade asap" - although see [1] for general feedback etc ]. If a new host is added to hosts.cfg with a noconn configuration in a new group or page configuratiopn eg page test Test group-compress <H3>Test</H3> 4.5.6.7 test #? noconn that server NEVER appears in the webpage as expected, although the new group does appear albeit then empty If it is introduced without that noconn parementer then it does as expected appear.? Then adding noconn to it subsequently does indeed drop the conn column and reproting then continues as normal. We have also found that specifying noping instead of noconn does include the server in the webpage with a white face in the conn column - ie it does get included, so is maybe a work round? at least) However... adding 4.5.6.7 test #? noconn to an already existing group/page - that server DOES get listed but with no subsequent tests against it - the line remains empty This would appear to be a feature of xymon Ive not come accrioss in 9+ years of using it.? [1] Anybody found any other "fixes" to be ablwe to sepcify noconn from the outset? I've googled but nothing appears to match that - though that could just be my rubbish googling skills... UPDATE:? deeper wierdness...? if i add a eg ssh test to that hosts.cfg line ...? then the server DOES get added...? cheers ian

I have installed xymon 4.3.30 on 3 servers. I am getting core dumps fo xymond_rrd on 1 on of the servers running Xymon 4.3.30.

Insert a newline into your custom xymon message?
by gabby.gibbons＠yahoo.com 24 Sep '20

Hello, I'm wondering if there's any way to insert a newline in a message. I know it's possible to do by actually putting it on another line in the script but I don't like the way that it looks because it messes up all the indenting in the script, so that's why I was wondering if there's a newline character that xymon supports, \n doesn't work it just append a literal "\n". An example of the way I can get it to work, but looks bad:MSG="${MSG}appended text" How I would like it work:MSG="${MSG}\nappended text" Thanks

Test for file existence/contents and send contents in alert
by zforray＠vcu.edu 23 Sep '20

23 Sep '20

I have a request to perform the following test and am not sure Xymon can do both parts of the request. If so, can someone show me how? I felt this is a FILE test to see if the file exists and/or is empty. This is their request: *The test should be added as a procruntime test.* *The test should look for the file /home/tomcat/alertbody.txt* *If the file is not present, the test result is OK.* *If the file is present, the test result is CRITICAL, and the contents of alertbody.txt should be sent to alert recipients (if that is possible).* -- *Zoltan Forray* IBM Spectrum Protect (p.k.a.

Double ports bug in xymonclient-linux.sh on RHEL6 RPM
by Scot.Kreienkamp＠la-z-boy.com 23 Sep '20

23 Sep '20

Has anyone noticed their ports information being displayed twice on RHEL/Centos6? I just noticed it tonight on some of my RHEL6 servers. It appears there's a bug in the RHEL6 Terabithia RPMs. >From RHEL6 RPM: echo "[ports]" # For some reason, the option for Wide/unTrimmed display of IPs # changed in netstat versions and no one provided backwards compat, # so exactly ONE of these should work successfully: netstat -antuT 2>/dev/null netstat -antuT 2>/dev/null Same lines from an RHEL7 RPM: # For some reason, the option for Wide/unTrimmed display of IPs # changed in netstat versions and no one provided backwards compat, # so exactly ONE of these should work successfully: netstat -antuW 2>/dev/null netstat -antuT 2>/dev/null Can someone fix and recompile the RHEL6 RPM?
