Changing parameter polling cycles

Collector and standard parameters use queries to obtain data from a monitored account. The poll time assigned to a collector or standard parameter sets the interval between executions of the query used by the parameter. The default out-of-the-box poll times that are set for collector and standard parameters are calculated to collect sufficient data to correctly monitor most systems.

If your system requires longer or shorter poll times, you can change the poll times, but keep the following in mind:

• Increasing poll times could cause you to receive late notification of problems.
• Decreasing poll times increases the resources used by the KMs, which could lead to performance problems.

• Poll times must exceed the amount of time it takes to execute the query and allow time for the parameter to parse and distribute the data obtained before it can resend the query. To avoid problems, use Debug to find the Query Execution Time before decreasing a poll time. 

  Warning

  Note

  If you change the poll time for a standard or collector parameter to an amount of time that is shorter than the amount of time it takes to complete the execution of the query used by that parameter, you might cause the parameter to go into an infinite loop, or other serious problems.

To change parameter polling cycle

1. In PATROL Configuration Manager, right-click the agent for whose parameters you want to schedule polling times.
2. Select Event Management > Parameter Settings.
3. Select the Polltimes tab.
4. Click Add Objects.
5. In the Object Selection dialog box, select the Get Objects From Agent option.
6. From the Hosts field, select the default host (/).
    The Application Classes field is populated with the application classes.
7. In the Application Classes field, select the application class for which you want to modify the parameters.
8. In the Instances field, select the instance for which you want to modify the parameters.
    The Parameters field is populated with the collector parameters.
9. Select the collector parameter, and click Add.
10. Click Close.
11. In the Event Management Parameter Settings dialog box, select the collector parameter from the Selected Objects List.
12. In the Set Polltime field, set the polling cycle as required.
13. Click Apply.
