You can tune the polling interval that each deployment manager or administrative agent uses to poll the job manager for jobs. The default polling interval is 30 seconds. With a larger polling interval, the rate at which the deployment managers or administrative agent contact the job manager decreases, which alleviates high processor usage. With a lower polling interval, jobs start running sooner.
To configure the polling interval of a deployment manager, the deployment manager must be running.
To configure the polling interval of an administrative agent, the administrative agent must be running.
The job manager processor usage increases as more nodes or deployment managers are registered with the job manager. This increase occurs even if a job is not submitted to the job manager. The job manager eventually runs at 100 percent processor usage as more nodes are registered. The threshold for the number of nodes that you can register with the job manager without high processor usage depends on the hardware capability of the machine that runs it.
This topic describes how to change the polling interval for the deployment manager or administrative agent using the administrative console.
You configured the polling interval.
Monitor the processor usage on the job manager. If the processor usage is still high, increase the polling interval. If jobs take too long to start, lower the polling interval.
