Monitoring activities
Use masks and filters to target the data that you collect and readjust the data collection interval to reduce the demand of monitoring activities on system resources.
Masks
The collection, summarizing, and writing of historical data using system resources.
Use masks to reduce the amount of resources required to retrieve data and improve response times for users. For example, you can select and exclude noncritical devices from monitoring. To find out how to use masks to filter data, see IBM Z OMEGAMON AI for Storage: User's Guide.
Data collection intervals
You must balance the requirement to collect sufficient information about monitored resources and the impact of this activity on system resources. If you can collect sufficient information about a monitored resource when you collect data every 60 minutes, set the data collection frequency to 60 minutes, and not to a lower frequency, such as 45 minutes.
