General system health and capacity checks
On the Dashboard (see
visible and that:
• The system didn't run out of capacity at any point in time. If the Capacity
Usage History graph shows spikes at or near the system's maximum
capacity, it may be time to add more.
• All the expected MCUs are connected, in service, and have the expected
capacities. If there appear to be issues with an MCU, check its
configuration and status, and if necessary, call Polycom Global Services.
See "Device Management"
• The H.323 Signaling Status section indicates the status of the gatekeeper
connection is OK, and that the network latency between the system and
gatekeeper is within the range you would expect for your network (it may
be helpful to keep latency records for comparison over time). If it isn't,
contact your network administrator or Polycom Global Services.
• The Network Status section shows the correct number of cluster members
(1 or 2), one of which is the active web host, and indicates that the network
interface(s) for the node(s) are in a good state (upward green arrow) and
have the expected speeds:
— For Private, 1000 Mbps / Full. Not applicable to a single-node system.
In a two-node system, errors on the private link may indicate a
problem with the system. Check the crossover cable connecting the
two servers. If necessary, shut down both servers, replace the
crossover cable, and restart the servers. If that doesn't solve the
problem, contact Polycom Global Services.
— For Public, the speed you expect for your enterprise network. Errors
on the enterprise link may indicate an error in the interface between
the Polycom DMA system and your enterprise network. Contact your
network administrator to resolve the issue.
• The System Information section shows information for one or two nodes,
depending on your system configuration. Verify that:
— The disk space usage for each node is less than 90% and Total memory
is greater than Free memory by at least 500 MB. If either is not true,
contact Polycom Global Services. If disk usage is too high, reduce the
number of days to retain log archives. See
on page 47.
— The time for each cluster node is correct and within a few seconds of
the other. If not, check your time configuration and NTP servers. See
"System Time"
Enterprise directory health
If the Polycom DMA system is integrated with an enterprise directory, check
the following (you must be logged in as an enterprise user):
"Dashboard" on page 156), verify that no alerts are
