More on Monitoring Alfresco in Nagios via OOTB support tools

Alfresco monitoring for Nagios via NRPE protocol

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
