Alfresco monitoring for Nagios via NRPE protocol - More on Monitoring Alfresco in Nagios via OOTB support tools

Last day we talked about monitoring Alfresco in Nagios via OOTB support tools addon using curl commands directly to the main webscripts, and parsing the obtained JSON information. Although this direct monitoring may be valid in many situations (if services available from monitoring server, if https..), other possibility is to run curl commands locally from Alfresco server and to obtain the information via NRPE protocol. This is the recommended use in case of JMX information via check_jmx plugin,

For using NRPE in Nagios, you must install nagios plugins and nagios-nrpe-server in your Alfresco Server, defining commands im NRPE configuration file:

$ sudo aptitude install nagios-plugins nagios-nrpe-server

/etc/nagios/nrpe.cfg

command[check_alf_active_sessions]=/usr/lib/nagios/plugins/check_ootb_active_sessions.sh 'localhost' '8080' 'monitor' 'secret' 'NumActive' '15' '20' 
command[check_alf_logged_users]=/usr/lib/nagios/plugins/check_ootb_active_sessions.sh 'localhost' '8080' 'monitor' 'secret' 'UserCountNonExpired' '15' '20' 
command[check_alf_number_tickets]=/usr/lib/nagios/plugins/check_ootb_active_sessions.sh 'localhost' '8080' 'monitor' 'secret' 'TicketCountNonExpired' '15' '20' 
command[check_alf_jvm_usedmemory]=/usr/lib/nagios/plugins/check_ootb_performance_stats.sh 'localhost' '8080' 'monitor' 'secret' 'UsedMemory' '3500' '4000'
command[check_alf_jvm_threads]=/usr/lib/nagios/plugins/check_ootb_performance_stats.sh 'localhost' '8080' 'monitor' 'secret' 'ThreadCount' '190' '195'
command[check_alf_process_load]=/usr/lib/nagios/plugins/check_ootb_performance_stats.sh 'localhost' '8080' 'monitor' 'secret' 'ProcessLoad' '75' '85'
command[check_alf_system_load]=/usr/lib/nagios/plugins/check_ootb_performance_stats.sh 'localhost' '8080' 'monitor' 'secret' 'SystemLoad' '85' '90'

and setting the corresponding allowed hosts (for your monitoring server). Finally, in your Nagios Server configuration you should use check_nrpe_1arg:

services_nrpe_ootb.cfg
