Cisco Cisco IP Contact Center Release 4.6.2 Maintenance Manual

ICM Message Delivery Service (MDS) Performance
Meter

There are overheads in maintaining MDS meters. The application needs to have a block of
memory that stores current counter data, and periodically it must update these values.
Furthermore, synchronizing access to the counter values adds serious burdens to the system.
For these reasons, the performance monitoring feature is turned off by default.

To turn on the feature, change one or both of the following registry key values to 1.

•For the MDS process (required for the Cisco ICM MDSPROC and Cisco ICM
MDSPROCCLIENT performance objects mentioned below):

•For the MDS client (required for the Cisco ICM MDSCLIENT performance object mentioned
below): 

where rtr (router) is an example of a <client>.

System Performance Monitor introduces overheads itself and the overheads depend on the
periodic update interval, which is set as the minimum 1 second by default. This interval should
be set reasonably high to minimize the impact on the system.

The assumption is that extensive metering will not be performed while the system is performing
as expected. Only in exceptional cases would close monitoring of the system be desirable.
