Configure Data Collection for a Server

You can configure data collection for individual servers. Use this procedure to configure specific servers to collect data for the data center. You can also select metrics to monitor, set threshold values for individual metrics, and include metrics in overall utilization.

Follow these steps:

1. Open the Explore pane.

   Available groups, services, and systems appear.

2. Open the Data Center folder, and select the service to which the server belongs.
3. Right-click and select Policy.

   The Policy submenu appears.

4. Click Metrics.

   The Metrics wizard opens.

5. Select the server for which you want to configure data collection.
6. Complete the following fields in the Set Interval dialog:

   Use Default

   Specifies the data center level as the default when selected. If you leave the check box cleared, the values that you specify are used instead.

   Data recording interval (seconds)

   Defines how often the data is collected and stored in the Performance DB.

   Default: 300 seconds

   Note: CA Technologies recommends that for every 1000 machines in your monitored environment, increase the data recording interval by 300 seconds.

   Daily roll-up data retention (days)

   Specifies how long to store the average of the daily data in the Performance DB.

   Maximum: 365

   Default: 365

   Polled data retention (days)

   Defines how long to store the polled data in the Performance DB. Consider the number of managed systems, services, and metrics collected when defining this number. The stored polled data objects accumulate over time and can impact performance. If performance issues arise, decrease the number of retention days.

   Default: 10 days

7. Select the metrics to monitor from the Available Metrics section and then click the down-arrow.

   The selected metrics are moved to the Selected Metrics to Collect section.

   Note: If you disable the default metrics (CPU and memory) and enable others, you will not see an overall utilization until you modify the thresholds of the newly selected metrics.

8. You can configure which performance metrics to monitor for each server and set threshold boundaries for each metric. Select the metric for which you want to set thresholds and complete the following fields:

   Upper Threshold

   Defines the upper limit of utilization for the selected metric group.

   Default: 80%

   Lower Threshold

   Defines the lower limit of utilization for the selected metric group.

   Default: 20%

   Include for Overall

   Specifies that you want the selected metrics to be included in the overall utilization calculation and evaluated by CA Virtual Assurance.

9. Click Finish to save your settings.
