collect statistics – regardless of the availability of the 5620 SAM Auxiliary Statistics
Collector workstations. At least one 5620 SAM Auxiliary Statistics Collector workstation
must be available for statistics collection to occur.
The 5620 SAM Auxiliary Statistics Collector is only supported with a distributed 5620
SAM Server and 5620 SAM Database.
For collection of performance management statistics from eNodeB network elements,
NTP should be used to synchronize the network element and the 5620 SAM Server and
5620 SAM Auxiliary Statistics Collector to ensure the statistics are successfully retrieved.
5620 SAM Auxiliary Call Trace Collector
This type of 5620 SAM Auxiliary collects call trace and information from WMM network
elements.
Up to two 5620 SAM Auxiliary Call Trace Collectors can be configured to collect call
trace information in 5620 SAM, and each of those collectors can be configured to be
redundant. Each 5620 SAM Auxiliary Call Trace Collector is installed on a separate
workstation. Each 5620 SAM Auxiliary Call Trace Collector is configured as a preferred
for the 5620 SAM Active Server and as a reserved for the 5620 SAM Standby Server.
This allows for a redundant 5620 SAM Auxiliary Call Trace Collector configuration.
Only one of the workstations in the 5620 SAM Auxiliary Call Trace Collector redundant
pair will collect the call trace information from the network elements at any given time
and the call trace information is synchronized between the Preferred and Reserved pair of
workstations. Information on the redundancy model of the 5620 SAM Auxiliary Call
Trace Collector can be found in
The 5620 SAM Auxiliary Call Trace Collector is supported with both a collocated 5620
SAM Server and 5620 SAM Database or distributed 5620 SAM Server and 5620 SAM
Database.
The 5620 SAM Auxiliary Call Trace Collector workstation must maintain consistent and
accurate time. It is encouraged to use an NTP service to achieve this. An alarm will be
raised if the times are not within 30 seconds.
5620 SAM Auxiliary Cflowd Collector
This type of 5620 SAM Auxiliary collects cflowd flow data from 7750 network elements.
The 5620 SAM Auxiliary Cflowd Collector operates in a standalone mode generating
IPDR files for the 7750 managed network elements that are configured to send cflowd
flow data to it where each 7750 can be configured to send cflowd flow data to multiple
5620 SAM Auxiliary Cflowd Collectors. Each 5620 SAM Auxiliary Cflowd Collector
will generate IPDR files for the cflowd data it is sent, resulting in duplicate data being
sent to the target file server.
