Changing Polling Intervals With the Monitoring Configuration File

You can modify default values for polling intervals for hardware health, OS resource utilization, and network reachability by editing the monitoring.properties configuration file.

The polling of network reachability is not possible if OS monitoring is not enabled.

If the monitoring.properties configuration file is not present, create it and save it in /etc/opt/sun/n1gc/monitoring.properties. The monitoring.properties is not created by default at installation.

Factory-configured default polling intervals are provided in the N1 System Manager software. These values are stated in seconds. The factory-configured defaults are provided in Table 5–3.

Any entries you make in the monitoring.properties configuration file overwrite these factory-configured defaults.

The minimum default polling interval that you can set is 60 seconds

The monitoring.properties configuration file exists only on the management server and not on provisionable servers. Modifying the default polling intervals stored in the monitoring.properties configuration file affects all the provisionable servers managed by the N1 System Manager.

You do not need to reboot the management server or the monitored provisionable server for changes to the monitoring.properties file to take effect.

Default polling intervals stored in the monitoring.properties configuration file apply to all servers unless specific values have been set at the command line for a specific server or group of servers. Set specific polling interval values by using the set command, as described in Setting Polling Intervals.

Tuning Polling Intervals for Your Installation

After a period of usage after installation and deployment, you can develop an awareness of how frequently you should be polling hardware health attributes and OS resource utilization attributes, and how often you need to poll your network reachability. Your configuration of the N1 System Manager depends on what your priorities are, in terms of crucial events. When setting polling intervals, or when changing default polling intervals, consider the number of servers you are managing with your N1 System Manager software. Consider also the application loads or application expected loads of your provisionable servers, and the capabilities of your network. Your expected responsiveness to events is also relevant. If you are able to react quickly to events as they occur, polling more frequently is appropriate.
