Job Agent

Overview

Job agent is deployed and run as a daemon/service on each target host to instantly run the job upon receiving a job from Job Server.

It always listen on default port 10055 and as soon as it receives a job, it start executing the given job(mostly in a form of shell script).

Either job finished successfully or unsuccessfully, Job agent always send the result to Job server.

It uses SQLite to store and manage the jobs internally.

Job agents are extremely efficient because of using native system calls.

Agent process

Job agent runs as a daemon process. The agent can be started by executing:

shell>/usr/sbin/jobarg_agentd

You can use the following command line parameters with Job agent :

-c --config <file>   Absolute path to the configuration file
-h --help            Give this help
-V --version         Display version number

Examples of command line parameters:

shell>/usr/sbin/jobarg_agentd -c etc/jobarranger/jobarg_agentd.conf
shell>/usr/sbin/jobarg_agentd -h
shell>/usr/sbin/jobarg_agentd -V

Process user

Same as Zabbix agent, Job agent is designed to run as a non-root user. However, if you want to run the process as root user then you have to change config AllowRoot parameter. Rather than running the processes with root user, it is recommended to use a sudo user.

Configuration file

See the configuration file options for details on configuring Job agent.
