The 2.4.X Centreon version are now stables for some times. Here is a small Howto explaining how to update your Centreon 2.3.x to the latest stable release date: Centreon 2.4.5.
I am currently using Centreon 2.3.8 on Centos 6.4. The broker is ndo2db with Nagios core. This tutorial is the next logical howto : Installing Centreon 2.3.8 on Centos 6.2. Approach is almost the same with Broker : Centreon-Broker.
Here’s how to update Centreon 2.3.8 to Centreon 2.4.5 with Nagios & ndo2db.
Check_oracle_health is a great Oracle Database monitoring Tools. This plugin help you retrieve a variety of data such as the time to connect to a database, the number of connected users, the invalid objects sum, free space in a tablespace and many other counters …
We will use it with Centreon to exploit check_oracle_health data monitoring as graphs. A dedicated Nagios part is also in this article.
Hello everyone, small tips if you have this king of error :
– ERROR while updating /var/lib/centreon/status/555.rrd at 1359215263 -> 100 : /var/lib/centreon/status/555.rrd: illegal attempt to update using time 1359215263 when last update time is 1359215263 (minimum one second step)
– ERROR while updating /var/lib/centreon/metrics/1461.rrd at 1359215263 -> 0.0 : /var/lib/centreon/metrics/1461.rrd: illegal attempt to update using time 1359215263 when last update time is 1359215263 (minimum one second step)
Use this command :
# chkconfig ntpd on
# ntpdate pool.ntp.org
# service ntpd start
This kind of error will disappear from logs 😉
In nagios, you will encounter this error”Argument “v6.0.1″ isn’t numeric in numeric lt (<)” with plugins like “check_snmp_ *” To solve this problem, just replace:
(Net::SNMP->VERSION < 4 )
(Net::SNMP->VERSION lt 4 )
On the line number corresdonding to this error in plugins.
This problem is due to the fact that plugins are quite old and libnet-snmp-perl has evolved.
