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  [[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 ==
 
{{Message/warning2 | You must configure a contacts file to be able to acknowledge [[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>
 
{{Message/warning3 | 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 ==
 
{{Message/warning2 | 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.
