Configuring Database Maintenance


To plot graphs and generate reports, OpManager collects data from the managed devices at regular intervals. By default, OpManager aggregates the performance data into hourly data at the end of each hour. The hourly data thus calculated will be aggregated into daily data at the end of each day. These aggregated data will be used in graphs and reports.


OpManager allows you to maintain the database with the required data. By default, the detailed data will be maintained for 7 days, the hourly data for 30 days and the daily data for 365 days. After the specified period, the database will be cleaned up automatically.


To configure your own settings for database maintenance, follow the steps given below:

  1. Click the Admin tab.
  2. Under Tools, click Database Maintenance.
  3. Specify the values for the following fields:
    1. Alarms Database- the maximum number of recent alarms to be maintained must be specified here. For instance, if you want an history of last 500 alarms, specify the value as 500 here.
    2. Events Database- multiple events correlate to generate a single alarm. This is essentially a history information.
    3. Performance Database- the cleanup interval of the raw data as well as the archived data must be specified here.
  4. Click OK to apply the changes.
