Modifying retention period for each of the aggregates

Products

• VMware Smart Assurance

Issue/Introduction

• Defining the retention period for each of the aggregates in MnR/Watch4net.
• Limiting data storage in MnR/Watch4net

Environment

Watch4Net/MnR - 7.x

Resolution

In the Watch4net, you can define the retention period for each of the aggregates in config.xml file. It is available in <APG_BASE>/Backends/APG-Backend/Default/conf/

User to review and edit this file based on their needs and available database space. For example, keeping 10 minutes aggregates for a very long period will create a huge database that will fill disk in a short time and will affect APG performances.

The name attribute of an aggregate refers to the aggregates defined in the aggregate definition file.

config.xml

      <group name="group">
      <raw-data span-time="31d"/>
      <aggregate name="1hour" span-time="61d"/>
      <aggregate name="1day" span-time="365d"/>
      <aggregate name="1week" span-time="2555d"/>

 

Aggregates
Recommended not to modify <APG_BASE>/Backends/APG-Backend/Default/conf/aggregates.xml, it is better to keep this file as is to preserve data integrity. It is always possible to edit this file when MnR/APG is installed, before starting to collect data. Make sure you keep a backup of the original file before modifying it. Backup any custom configuration you made because this file can be modified when proceeding to an upgrade procedure.
