Activity Monitoring Overview

Activity Monitoring Overview

Activity monitoring can be useful for tasks such as:

• Monitoring the system health—Using the dashboard provides a quick window into your InterSystems IRIS® system performance. If the message duration or queue size is growing, it may indicate a performance issue.

• Trouble shooting problems—Using the dashboard can help diagnose a current or past problem. You can use it to determine if a specific configuration component was the primary cause of a performance bottleneck.

• Tracking performance and activity growth to aid in capacity planning—By reviewing long-term changes in message volume you may be able to estimate future growth. You can plan for increased capacity before encountering a significant performance issue.

The Activity Monitoring package provides:

• A centralized store for message statistics.

• A data model that makes it easy to analyze and report on the statistics using SQL or MDX.

• A dashboard showing message current message rates and response times for each interface.

• Variable granularity for long term and short term statistics.

• Long term storage of message statistics available for historic reporting.

• Custom statistic collection using application specific metrics.

This package stores summary statistics that contain information such as the number of messages that pass through a configuration component and the average time to process the message. This summary information is stored in a compact, efficient manner and can be maintained over very long periods of time without requiring extensive amounts of storage.

The monitor provided with this feature allows you to display the current data over several different time periods. But the statistics stored in the database provide a richer set of data. You can use the analysis and reporting tools of your choice to analyze long-term trends or to compare the volume trends during peak traffic times. This capability allows you to analyze and troubleshoot problems with overloaded components and to track long-term load changes so that you can provide additional resources before problems develop.

All classes that inherit from Ens.BusinessServiceOpens in a new tab, Ens.BusinessProcessOpens in a new tab, or Ens.BusinessOperationOpens in a new tab can use the built-in activity monitoring. In addition, you can use custom code to include custom data in your activity monitoring.

The Activity Volume Statistics and Monitoring package allows you to monitor multiple namespaces running on a single instance of InterSystems IRIS and collect the statistics from these namespaces in a single database.
