Workflow for path and prefix monitoring
Stages
1 | Determine the map type you want to view: |
2 | Enable NFM-P performance statistics collection for IP and MPLS interfaces, and for LSPs. Configure the MIB entry policy for the required statistics object type, or class; see the procedure “To configure polling for a MIB statistics class” in the NSP NFM-P Statistics Management Guide. Set the Administrative State parameter in the MIB entry policy to Up.
Set the polling interval to less than one hour. |
3 |
For LSP utilization history: on the Accounting tab of the Dynamic LSP properties form for each LSP, assign an accounting policy and set the Administrative State to Up. See the procedure “To create a Dynamic LSP” in the NSP NFM-P Classic Management User Guide. |
4 | Configure monitoring, as required.
|
5 |
Create a size constraint policy to specify the maximum number of historical path records that the CPAM retains, if required. See To configure the size constraint limit for path monitor records for more information. |
6 | View path records and historical path records, as required
|
7 |
View status change history of monitored prefixes, if required. See To view status change history of monitored prefixes for more information. |
8 |
View the total cost of IP paths and IP path segments, if required. See To view the total cost of IP paths and IP path segments for more information. |
9 |
Navigate to a dynamic LSP or a monitored path on a topology map, if required. See To navigate to a dynamic LSP on a topology map and To navigate to a monitored path on a topology map for more information. |
10 | Determine the cause event of an IP or LSP path record, as required. Alternatively, navigate from a cause event to the IP or LSP path record of the monitored path, or navigate to the cause event of a path record of GRE or MPLS service tunnels.
|
11 | Sort records, as required.
