Test Generator (im_testgen)
This module generates simple events for testing, with an incremented integer up to the number of events specified by the MaxCount directive.
To examine the supported platforms, see the list of installation packages. |
Configuration
The im_testgen module accepts the following directives in addition to the common module directives.
Examples
This configuration generates ten unstructured events defined in the MaxCount
directive and then stops generating events.
<Input testgen>
Module im_testgen
MaxCount 10
</Input>

This configuration generates ten events defined in the MaxCount
directive and pares them into a JSON format as a structured output.
<Extension json>
Module xm_json
</Extension>
<Input testgen>
Module im_testgen
MaxCount 10
Exec $Message=$raw_event; json->to_json();
</Input>

}
This configuration generates ten events defined in the MaxCount directive. Then, the Schedule block restarts the module to start generating events again, going into a cycle of generating ten events every 5 seconds.
<Extension json>
Module xm_json
</Extension>
<Input testgen>
Module im_testgen
MaxCount 10
Exec $Message=$raw_event; json->to_json();
<Schedule>
Every 5 sec
Exec module_restart();
</Schedule>
</Input>
MaxCount is only reset on module restart starting from NXLog Agent version 6.2.

This configuration generates a continuous event stream where the module waits for 100000 microseconds between generating events. It roughly equals to around ten events generated per second.
<Input testgen>
Module im_testgen
Exec sleep (100000);
</Input>
This configuration generates a continuous event stream where the module waits randomly between 0 to 2000 microseconds within generating events.
<Input testgen>
Module im_testgen
Exec sleep (get_rand(2000));
</Input>
