What Basic Functions Can I Perform in Cisco MGM?
2.2.5 Refreshing Data
Many Cisco MGM windows have a Refresh Data tool that refreshes all data being displayed by Cisco
MGM. There are two versions of the Refresh Data tools, and both refresh data from either the server or
the database.
• The Refresh Data tool flashes when updates are available. This tool has two modes: manual refresh
and autorefresh.
• The Refresh Data tool does not notify you that updates are available. You must click the tool to
retrieve updated data.
Note Clicking Refresh Data in the Domain Explorer window refreshes all data for the entire Cisco MGM
client. Depending on the number of NEs in your network, you might experience a delay while the data
refreshes.
2.2.6 Pruning the Database
Cisco MGM automatically prunes various categories of Cisco MGM data that tend to accumulate over
time and would otherwise exhaust the available disk space. See 5.1.4 Pruning the Database. You can
configure the following categories of data for automatic pruning:
• PM data
• FM data
• Audit log data
• Error log data
• Self-monitor data
• Job monitor data

Indeterminate, and/or Cleared.

particular destination. You can also overwrite or append the file.
Export Options Allows you to specify the field separator type. Types include Comma, Tab,
Semicolon, or Other, an option you use to specify a different separator. You can also
check the Stop export when check box and enter a number of records to instruct the
Event Export Manager to stop exporting after the user-specified number of records
are logged.
