Monitoring of ColdFusion with Nagios

For Windows:
First, you'll need to install the NRPE_?NT dae­mon on each of the Win­dows servers you have run­ning CF. Fol­low the instruc­tions within the zip to install. It just works.

Add Coldfusion host to hosts.cfg
If your CF servers aren't already among the hosts you're mon­i­tor­ing, add them to hosts.cfg. A typ­i­cal host def­i­n­i­tion looks sim­i­lar to the one below.

Add host groups for your Coldfusion server
Assum­ing all your CF servers are run­ning the same CF ver­sion, you can make a Nagios host group for those servers. This is much less work than adding indi­vid­ual servers to the ser­vice check (detailed below). If you have servers run­ning dis­parate CF ver­sions, set up a host group for each. Add your host group defin­tion to hostgroups.cfg. A typ­i­cal host group def­i­n­i­tion looks sim­i­lar to the one below.

Add Coldfusion commands to checkcommands.cfg
In a default Nagios instal­la­tion, checkcommands.cfg con­tains all the def­i­n­i­tions of the com­mands Nagios uses to inspect ser­vices run­ning on the hosts it mon­i­tors. The fol­low­ing list of com­mand def­i­n­i­tions should cover Cold­Fu­sion 7 (and will likely also cover other versions (not checked)). Add the fol­low­ing lines to checkcommands.cfg.

The last two com­mands in the above list­ing check actual CF processes run­ning on the server. Note the com­ments. The val­ues we use may well be very dif­fer­ent in your envi­ron­ment. The eas­i­est way to check is to have a look at what your servers are doing and make an edu­cated guess at the needed lev­els in your setup. No harm done if you use these val­ues, you just may end up get­ting copi­ous noti­fi­ca­tions from Nagios that you don't need (or con­versely, no noti­fi­ca­tions at all). Test and tweak.

*Adding CF-??related ser­vices to services.cfg*
Nagios' mon­i­tor­ing model is cen­tered on the con­cept of ser­vices, so this step is per­haps one of the most impor­tant. You need to add ser­vice def­i­n­i­tions to services.cfg for each of the com­mand def­i­n­i­tions you built ear­lier. A cou­ple of sam­ple ser­vice def­i­n­i­tions are shown below.

Restart Nagios
At this point, Nagios should be ready, will­ing and able to mon­i­tor CF on your Windows-??based CF servers. Restart Nagios by whichever method you use. After restart­ing, if you log into the Nagios web inter­face, you should be able to see the CF ser­vices you set up being monitored.

ColdFusion installed on Linux
The above works good for Coldfusion installed on Windows. The below steps should help to get it going when Coldfusion is installed on Linux, but has not been tested!

Use "pstree" com­mand in bash script:

This will print a CFChil­dren vari­able like:

and the results of the script can be exported within snmp; an entry in snmpd.conf like:
exec .1.3.6.1.4.1.2021.500 coldfusion-??threads /usr/local/bin/coldfusion-threads-snmp.sh will do it.
