Recommended Regular Maintenance
Perform the following tasks to keep your Polycom RealPresence DMA system operating trouble-free and at peak efficiency. These tasks can be done quickly and should be run at least weekly.
You should archive your backups regularly.
To archive backups:
1Log into the Polycom RealPresence DMA system
If there are new backups, download and archive the latest one. Delete backups after downloading in order to free up disk space.
Every night, each Polycom RealPresence 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.
Check General System Health and Capacity
You should check your system’s general health and capacity regularly.
To check your system’s general health and capacity:
1On the Dashboard, verify that:
aThere are no alerts indicating problems with any part of the system.
bThe 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.
cThe 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:
2Go to and download and delete backup files.
3Go to and download and delete log file archives (you must have the Auditor role to do so.
4Go to and reducing the retention period for log archives.
5Go to and reduce the retention values (you must have the Auditor role to do so.
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.
6Go to and view the graph for each cluster with the following capacity-related metrics selected:
ØCall 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.
ØConference Manager Calls – If the number of concurrent calls approaches the number of MCU ports available, you may need to add MCU capacity.
ØView 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.
Check Microsoft Active Directory Health
If your RealPresence DMA system is integrated with a Microsoft Active Directory, you can check the health of the Active Directory system.
To check your Microsoft Active Directory health:
1Go to .
2Check the status and results of the last cache update, and verify that membership information for imported groups, if any, was successfully loaded.
4Go to and verify that the number of orphans is not unexpectedly large.
Check Security Configuration
You should regularly check your RealPresence DMA system’s security configuration.
To check your system’s security configuration:
Go to and verify that the security settings are what you expect. Any departure from the settings you expect to see may indicate that your system has been compromised.
You should regularly check the certificates installed on your RealPresence DMA system.
To check your system’s certificates:
1Go to and verify that the list of certificates contains the certificates you have installed (an archived screen capture may be helpful for comparison).
2Display the details for each certificate you have installed and verify they are accurate (again, an archived screen capture may be helpful for comparison).
Check Network Usage Data Export
You can check your network usage data export. The RealPresence DMA system stores up to approximately 1 GB of network usage data, deleting the oldest as needed. Data size is based on site topology complexity, not usage. On a system with the largest supported site topology, it’s only one day’s worth of usage data, but most systems should retain data for a substantially longer period.
To check your network usage data export:
Determine an appropriate download interval for your site topology and download network usage data to your local computer during that interval.
If you want to preserve detailed call and conference history data in spreadsheet form off the Polycom RealPresence DMA system, periodically download the system’s CDR (call detail record) data to your PC. See Call Detail Records.
