68 — Performance statistics collection
Alcatel-Lucent 5620 Service Aware Manager, Release 7.0 R6 December 2009 68-3
3HE 04551 AAAE Ed. 01 Statistics Management Guide
Table 68-1 MIB statistics policy overrides
NE MIB policies can be specified in NE discovery rules to ensure that statistics
collection starts immediately after the NE is discovered. Specific MIB polices must
be updated manually for specific objects on the new NE after it is discovered or new
objects are created.
For top-down performance statistics configuration, choose ToolsStatisticsMIB
Policies from the 5620 SAM main menu to systematically configure statistics for the
network. For bottom-up performance statistics configuration, configure the MIB
entry policy from the Statistics tab of the properties form for a specific object.
Generic NE performance statistics support
The 5620 SAM supports the collection of a limited set of statistics counters from
standard system, interface, and routing MIBs on generic NEs. These statistics are
processed and presented in the same manner as statistics from other devices. You can
view generic NE statistics on the Statistics tab of a generic NE interface properties
form, retrieve them using the OSSI, and display them graphically using the
5620 SAM Statistics Plotter.
68.2 Workflow for performance statistics collection
1 Configure the MIB statistics policy for NEs. See Procedure 68-1 for the top-down
method. See Procedure 68-2 for the bottom-up method.
2 Configure the MIB statistics policy for specific objects. See Procedure 68-3 for the
top-down method. See Procedure 68-4 for the bottom-up method.
3 Specify the MIB statistics policy polling interval. See Procedure 68-5 for more
information.
For a given object
NE MIB policy Specific MIB policy Action
Collect Collect Statistic is collected once
Do not collect Do not collect Statistic is not collected
Collect Do not collect Statistic is not collected
Do not collect Collect Statistic is collected
Note 1 — To collect or view generic NE statistics from routing MIBs,
you require a valid 5650 CPAM license that has a third-party router
quantity greater than zero.
Note 2 — If persistent SNMP indexes are not enabled on a generic
NE, one or more generic NE interface indexes may change after a
generic NE reboots. This can cause a mismatch between the statistics
records collected before the reboot and the current interface indexes.
The 5620 SAM takes no action to recognize or correct such a
mismatch.
