Polycom 3725-76302-001LI manual General system health and capacity checks

DMA Operations Guide Recommended Regular Maintenance

Every night, each Polycom DMA system cluster determines whether its configuration or local user data have changed. If so, it creates a configuration-only backup of the system. For details on backups, see “Backing Up and Restoring” on page 381.

General system health and capacity checks

On the Dashboard (see “Dashboard” on page 352), verify that:

•There are no alerts indicating problems with any part of the system.

•The Supercluster Status pane shows the correct number of servers and clusters, and the network interfaces that should be working (depending on your IP type and split network settings) are up (green up arrow) and in full duplex mode, with the speed correct for your enterprise network.

•The Cluster Info pane’s Resources section shows that there is adequate free disk space. If the system is using more than 80% of disk space, free up space by doing some or all of the following:

—Go to Maintenance > Backup and Restore and download and delete backup files (see “Backing Up and Restoring” on page 381).

—Go to Maintenance > System Log Files and download and delete log file archives (you must have the Auditor role to do so; see “System Log Files” on page 377).

—Go to Admin > Local Cluster > Logging Settings and reducing the retention period for log archives (see “Logging Settings” on page 81).

—Go to Admin > Call Server > History Retention Settings and reduce the retention values (you must have the Auditor role to do so; see “History Retention Settings” on page 281).

•The Territories Status pane shows that all territories have the correct capabilities, are being managed by their primary cluster, and (if your deployment is so configured), have a backup cluster.

Go to Reports > Network Usage (see “Network Usage Report” on page 426) and view the graph for each cluster with the following capacity-related metrics selected:

•Call Counts — If the number of concurrent calls approaches the license limit, you may need to rebalance territory responsibilities, add licensed capacity, or add another cluster.

•Conference Manager Calls — If the number of concurrent calls approaches the number of MCU ports available, you may need to add MCU capacity.

View the graph for each site, site link, and subnet with Calls Dropped and Calls Downspeeded selected. These metrics show only calls dropped or downspeeded due to insufficient bandwidth at the selected throttlepoint. Any values above zero are indicators of bandwidth saturation and suggest that it’s time to increase network bandwidth.
