Configure Metric Filtering

Metric filtering reduces the storage footprint of collected performance data by limiting the metrics collected from a metric family for a particular monitoring profile. For devices in associated collections, only the selected metrics are loaded.

Metric filtering reduces the storage footprint of collected performance data by limiting the metrics collected from a metric family for a particular monitoring profile. For devices in associated collections, only the selected metrics are loaded.
The following example helps to describe the behavior for multiple monitoring profiles.
Example:
  • One monitoring profile (A) has no metric filtering.
  • Another monitoring profile (B) has some metric filtering to collect only BitsIn, BitsOut.
  • Each monitoring profile is associated with a different collection.
Result:
  • If a device ends up in both collections, the configuration from (B) takes priority. The system only collects BitsIn, BitsOut.
If a device is associated with multiple monitoring profiles, all selected metrics from all monitoring profiles are collected and saved for the device at the fastest rate among all monitoring profiles.
Storage savings are not linear. To estimate the storage savings, use the
CA Performance Management
Sizing Tool
. For existing devices, the storage savings is not fully realized until previous poll results and rollup data reach the limit of the data retention policy. For more information, see Configure Data Retention Rates.
Metric filtering can only be applied to custom monitoring profiles. You cannot apply metric filtering to a monitoring profile with a lock icon.
Metric filtering does not reduce SNMP traffic. Filtered metrics are still polled. Metric filtering applies only to metrics collected through SNMP.
Filtered metrics are still available for selection when building dashboards or configuring event rules for thresholds. Consider dashboard and threshold requirements before you filter a metric.
Follow these steps:
  1. Hover over
    Administration
    , and click
    Monitored Items Management: Monitoring Profiles
    .
  2. Select the monitoring profile, and click the
    Metric Families
    tab.
  3. Select the metric family, and click
    Edit Collected Metrics
    .
  4. Move the metrics to collect to the
    Selected
    pane.
    By default, all metrics are selected. To pick a limited set of metrics, select all metrics, and move the metrics to the
    Available
    pane. Then move the metrics to collect to the
    Selected
    pane.
  5. Click
    Save
    .
    Only the selected metrics are loaded to the Data Repository for devices in collections associated with the monitoring profile.
    If the collection is associated with another monitoring profile that includes the same metric family, or if the devices are in another collection associated with a monitoring profile with the same metric family, the metrics are still collected.
To view the metrics that are collected for a particular device, go to the device administration page, click the
Metrics
tab, and select a metric family. A column in the right pane indicates where the metric is collected.
This tab represents consolidated information across all monitoring profiles associated with all collections the device belongs to. If you see a metric that you do not want to collect, view the metric families associated with each monitoring profile for each collection.
