4 Network Appliance Filer

Note:

Network Appliance Filer-related metrics are not part of the System Monitoring Plug-in release. They are part of the Enterprise Manager Grid Control release.

You can use the All Metrics page for a Network Appliance Filer target in the Enterprise Manager Grid Control to view the metrics that have been collected for that target by the Oracle Management Agent.

The Network Appliance Filer metrics provide description, summary, multiple threshold (where applicable), data source, and user action information for each metric.

The following abbreviations are used in this chapter:
