| |
| | |
| Purpose: This SOP is to describe nagios configurations
| |
| | |
| = Initial Configuration =
| |
| == CGI Access ==
| |
| To view information in nagios (anything with cgi-bin in the path) you need to be able to grant yourself access. After checking out the Puppet CVS tree as described in the [http://fedoraproject.org/wiki/Infrastructure/SOP/Puppet Puppet SOP] you first need to edit configs/system/nagios/cgi.cfg and append your FAS username to 'authorized_for_system_commands'
| |
| == Contact Information ==
| |
| {{Template:Warning}} You must configure a contacts file to be able to acknowledge [http://fedoraproject.org/wiki/Infrastructure/SOP/Outage outages]
| |
| Create a new file named 'fasname.cfg' in configs/system/nagios/contacts/ with the following details:
| |
| <pre>
| |
| define contact{
| |
| contact_name fasname
| |
| alias Real Name
| |
| service_notification_period 24x7
| |
| host_notification_period 24x7
| |
| service_notification_options w,u,c,r
| |
| host_notification_options d,u,r
| |
| service_notification_commands notify-by-email
| |
| host_notification_commands host-notify-by-email
| |
| email Email address (any)
| |
| }
| |
| </pre>
| |
| {{Template:Caution}} Using the 24x7 notification period may cause duplicate messages if you are a member of sysadmin-main, in which case you can specify 'never' instead
| |
| | |
| Next append your name to the 'members' section of configs/system/nagios/contactgroups/fedora-sysadmin-email.cfg
| |
| | |
| == nagios-external ==
| |
| The same changes will need to be applied with the nagios-external configuration (configs/system/nogios-external)
| |
| | |
| == Commit Changes ==
| |
| {{Template:Warning}} Remember to "cvs add" the contacts/fasname.cfg files
| |
| | |
| Commit changes by running cvs commit -m "Adding fasname to Nagios" and then mark the changes for distribution by make install
| |
| | |
| = Understanding the Messages =
| |
| == General ==
| |
| Nagios notifications are generally easy to read, and follow this consistent format:
| |
| <pre>
| |
| ** PROBLEM/ACKNOWLEDGEMENT/RECOVERY alert - hostname/Check is WARNING/CRITICAL/OK **
| |
| ** HOST DOWN/UP alert - hostname **
| |
| </pre>
| |
| Reading the message will provide extra information on what is wrong.
| |
| | |
| == Disk Space Warning/Critical ==
| |
| Disk space warnings normally include the following information:
| |
| <pre>
| |
| DISK WARNING/CRITICAL/OK - free space: mountpoint freespace(MB) (freespace(%) inode=freeinodes(%)):
| |
| </pre>
| |
| | |
| A message stating "(1% inode=99%)" means that the diskspace is critical '''not''' the inode usage and is a sign that more diskspace is required.
