Oracle monitoring with dbcheck fails
by Johan.Grotherus＠vattenfall.com 16 Sep '15

16 Sep '15

Hi all, I am currently under way migrating from my current Xymon server running on Ubuntu to redundant Xymon servers running on CentOS. I am having Oracle monitoring enabled with dbcheck on my Ubuntu server and it is working fine, but the same setup does not work on CentOS. 1. The oracle client is installed 2. All required perl modules are installed 3. The same dbcheck.ini file used on Ubuntu has been copied over to CentOS 4. The dbcheck task is running 5. ORACLE_HOME and LD_LIBRARY_PATH has been set 6. I can connect to all my monitored Oracle instances with: sqlplus64 xymonuser/xymonpassword at host/SID as the Xymon user 7. The following perl script gives no error output #!/usr/bin/perl use DBI; $ENV{'ORACLE_HOME'}="/usr/lib/oracle/11.2/client64/"; $dbhost="hostname"; $port=1521; $sid="SID"; $user="xymonuser"; $pw="xymonpassword"; $data_source="DBI:Oracle:host=$dbhost;port=$port;sid=$sid"; $dbh = DBI->connect($data_source,$user,$pw ,{ RaiseError => 1, PrintError =>1}); $dbh->disconnect; exit 0; However, the only thing I get in the dbfast.log is: Timeout connecting to DBI:Oracle:host=hostname;port=1521;sid=SID! This is weird, and it got even more weird when I realized that dbcheck does not even try to communicate with the Oracle instances, it simply logs the error message and exits. I ran tcpdump to verify this and there is no connection attempt being made by dbcheck. The only thing that really differs between the Ubuntu machine and the CentOS machine are the version numbers for certain per modules: Ubuntu looks like this: 2015-09-15 08:56:42 Using default environment file /usr/lib/xymon/client/etc/xymonserver.cfg Program Information dbcheck.pl version 1.09 Hobbit_fd_lib.pm version 1.16 OS Information Linux hmon01 3.13.0-63-generic #103-Ubuntu SMP Fri Aug 14 21:42:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Perl version is v5.18.2 Module Information FindBin 1.51 POSIX 1.32 Text::Wrap 2012.0818 Time::Local 1.2300 Sys::SigAction 0.20 Config::IniFiles 2.82 DBI 1.63 DBD::DBM 0.08 DBD::ExampleP 12.014311 DBD::File 0.42 DBD::Gofer 0.015327 DBD::ODBC 1.45 DBD::Oracle 1.74 DBD::Sponge 12.010003 DBD::mysql 4.025 CentOS looks like this: 2015-09-15 08:55:28.619868 Using default environment file /home/xymon/server/etc/xymonserver.cfg Program Information dbcheck.pl version 1.09 Hobbit_fd_lib.pm version 1.16 OS Information Linux hxm01.ds.driss.se 3.18.17-13.el6.x86_64 #1 SMP Tue Jul 21 17:17:17 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Perl version is v5.10.1 Module Information FindBin 1.50 POSIX 1.17 Text::Wrap 2009.0305 Time::Local 1.1901 Sys::SigAction 0.11 Config::IniFiles 2.56 DBI 1.609 DBD::DBM 0.03 DBD::ExampleP 12.010007 DBD::File 0.37 DBD::Gofer 0.011565 DBD::Oracle 1.74 DBD::Sponge 12.010002 DBD::mysql 4.013 So, I must be missing something, but I have not found what that is, any ideas? /Johan

link@ip feature
by ksp＠stougaards.dk 16 Sep '15

16 Sep '15

Hi Xymon' I kind a like this feature and the result which I've found on xymon.com under Services https://www.xymon.com/services/services.html # The link test does a port 80 check to the IP listed here. Since we use "testip", the IP cannot be NULL. The IP listed must respond on port 80. testip link at 192.168.1.1 COMMENT:"Cable link" But which version of xymon is it working on? I'm using Debian 7 and Xymon 4.3.20 There is also the IP test next to Link and it seems to me that these two are going together. Can anyone give some hint to me for getting this to work? Script or configuration change? Regards Stougaards

xymonton?
by christian.becker＠rhein-zeitung.net 16 Sep '15

16 Sep '15

Hello out there, in the past every now and then i looked to the xymonton website www.xymonton.org<http://www.xymonton.org> for new monitors and plug-ins. Now this site seems to be down? Can anybody tell what happened to this site? Are there other resources on the web where I might have a look for interesting additional xymon stuff?

reading /var/log/messages
by oogiejonz＠yahoo.com 15 Sep '15

15 Sep '15

We just set up splunk in our environment and have made all our /var/log/messages owned by root:splunk mode 640 so that splunk can read and index these files. I was thinking I could add xymon user to splunk group and that would allow xymon to read /var/log/messages as well, but it doesn't seem to be working. I can read /var/log/messages as the xymon user but the msgs web page is still showing Cannot open logfile /var/log/messages : Permission deniedAny ideas on what else I can do to allow xymon to get these logs?

Windows Powershell client v2.03
by zak.beck＠accenture.com 15 Sep '15

15 Sep '15

I have today committed v2.03. Changes: * increased space for PID column on cpu screen * add process start time and elapsed time (in minutes) to proc screen * enable checking group policy for tssessions directive * enable 'tssessions' to be used as an alias for terminalservicessessions in the client local config, to match the on-screen heading * add processruntime (alias: procruntime) , to send an alert when a process has been running for a defined number of minutes The XymonPSClient.doc file has been updated to include better information for installation. The Readme.txt file has been updated to point to the XymonPSClient.doc file. In case you missed it, v2.02 renamed adreplicaton test to adreplication. This may impact any alerts you have setup for this test. Zak

Ongoing problem with multiple recovery notices with on a few tests
by larry＠fni-stl.com 14 Sep '15

14 Sep '15

I'm having an ongoing problem with multiple recovery notices. I was really hoping that 4.3.21 would have fixed it but not so. The alert picks up the correct rule and stops at line 473. Recover hits that rule then continues on down the list. It will then duplicate on a secondary matching rule line 482 and then on my catch all default rule line 618. This isn't on all alert recoveries. Mostly appears to only happen on "server" names that have an underscore or dash in it. That may just be a coincidence. Attached is a snapshot of my email notices showing the problem. It's really a small percentage of my total alerts that do this. But that subset will do it consistently. There has to be something different about that group. I got a response from J.C. on this around 3/4/15. He and I agreed that the problem is most likely in lib/loadalerts.c. Which is a pretty complicated piece of code. ANYWAY, I wanted to see if anyone else is experiencing this and, if so, were you able to adjust or work around it. It isn't a major problem. Just an annoyance.

Migrating away from SourceForge?
by markus.stoll＠junidas.de 12 Sep '15

12 Sep '15

yes, why not migrate to github or something like it. Probably I am not aware of all aspects how things are handled currently, but I would expect better contribution handling and issue tracking with github. For example what I do not understand, why is there a patched version of xymon in Debian, enhancing time resolutions, and why did these patches never make it back into xymon?

custom files consumed by BB Client
by dito74＠gmail.com 12 Sep '15

12 Sep '15

I'm still trying to migrate all the infrastructure away from the old ancient BB into XYMon, I am done with the server, I am now trying to migrate all the clients to BBWin (or WinPSClient" if that's what I'll need to do. The problem is that the BB client used to pick up everything inside the Log folder specified and send it to the server, consuming all the files in there. So we have some .Net code that used to write ALC so that we know that data is flowing back and forth keeping the ALC lights Green at all the time. When there is a problem, it goes purple because files are not being written in there (or else) and I get paged. So now my question is, how can I migrate this to BBWin, do I need to install the FSMon External and monitor a folder where I am going to write the ALC? Thank you, Gab
