Nagios® is an Open Source System Monitor that is available at http://www.nagios.org. An ecosystem of more or less compatible System Monitors has evolved, e.g. op5®, that makes use of a similar design and configuration.
You can monitor JobScheduler by use of Plugins that check the availability of the daemon/service.

Parameterization

Parameter

	Default	Description
-j	--joc-url	—	Url of JOC Cockpit (http or https are supported)
-i	--id	—	Id of a JobScheduler Cluster
-a	--account	—	Account for HTTP authentication to JOC Cockpit (=<user:password>)
-H	--hostname	—	Name or IP address of a JobScheduler Master host. Only required to check a specific cluster member
-p	--port	—	HTTP port that JobScheduler listens to (`40444`). Only required to check a specific cluster member
-t	--timeout	30s	Timeout for establishing the connection to JOC Cockpit
-d	--detailed	—	If set and the Cluster has more than one Master and not all Masters are running then the message contains host:port of each Master

title	Sample JobScheduler Agent Command parameterization

http://galadriel.sos:4445/jobscheduler/agent/api/overview!'{totalTaskCount},{currentTaskCount}'!'{startedAt},{totalTaskCount},{currentTaskCount},{isTerminating}'!20

Parameterization

Parameter

		Default	Description
-u,	--url	—	URL for the HTTP connection that addresses the Agent via host (`galadriel.sos`) and port (`4445)` that the Agent is listening to followed by a fixed path (`/jobscheduler/agent/api/overview`).
-a	--attributes	—	List of attributes that are used to check the Agent availability. The specified attributes are recommended to check if the Agent answer if formally correct.
-o	--outputvars	—	List of attributes that are used for output of the script and that will be displayed in the System Monitor `startedAt`: point in time when the Agent was started. `totalTaskCount`: total number of jobs that have been executed during the lifetime of the Agent. `currentTaskCount`: number of jobs that are currently executed by the Agent. `isTerminating`: indicates whether the Agent is currently shutting down. Depending on the shutdown command that has been used an Agent will let run currently executed jobs before terminating
-t	--timeout	15s	Timeout for establishing the connection to the Agent

Notes

Consider the use of the HTTPS protocol instead of the HTTP if the Agent is configured for use with Secure HTTPS communication.
Perl > 5.8 is required and some Perl packages are required. You can download and install Perl packages from e.g. http://www.cpan
- HTTP::Request::Common
- LWP::UserAgent
- JSON
- ```
Data::Dumper

Parameter

		Default	Description
-j	--joc-url	—	Url of JOC Cockpit (http or https are supported)
-i	--id	—	Id of a JobScheduler Cluster
-a	--account	—	Account for HTTP authentication to JOC Cockpit (=<user:password>)

-t	--timeout	30s	Timeout for establishing the connection to JOC Cockpit
-d	--detailed	—	If set and the Cluster has more than one Master and not all Masters are running then the message contains host:port of each Master

Example:

Code Block

language	bash
title	Example Active Check for all JobScheduler Agents with JOC Cockpit

#JobScheduler running with the id 'test' and JOC Cockpit has the url http://localhost:4446 where the account (user and password 'test') has access
 
<path_to_plugins>/check_jobscheduler_agent_with_joc.pl -j http://localhost:4446 -i test -a test:test

...

check_jobscheduler_agent_with_joc.pl calls an optional script report_jobscheduler_agent.pl per Agent.
This script does not connect to JOC Cockpit or perform any checks but simply serves to create individual notifications per Agent to the System Monitor.
The script is executed if it is available from the same directory as the calling script and has to be executable.

The script is parameterized to transfer the message type and notification to the System Monitor.

report_jobscheduler_agent.pl <joc-cockpit-url> <scheduler-id> <agent-url> <agent-status>
<joc-cockpit-url> is the URL that has been specivied as a parameter to the script check_jobscheduler_agent_with_joc.pl
<scheduler-id> is the JobScheduler Master ID that has been specified as a parameter to the script check_jobscheduler_agent_with_joc.pl
<agent-url> is the URL identifying the Agent

<agent-status> is one of "RUNNING" , "UNREACHABLE", "TERMINATING", "UNKNOWN_AGENT"
