Graphing E1 circuit usage on Cisco Call Manager

Hi,

I would like to graph the E1 circuit usage (i.e concurrent calls over time) on each of our sites voice gateways. We use Cisco Call Manager 4.1.3 and our gateways run MGCP. Any help would be greatly appreciated on what OID to use etc. I've tried quite a few but none seem to work and there's not much info out there on what to use.

Thanks

I monitor active sessions on a PRI (T1) with OID 1.3.6.1.4.1.3076.2.1.2.17.1.9. I used SW SNMP MIB Browser to get that OID. I don't have any E1's so that's as close as I can get it for you.

That OID did not work for my PRI T1 lines but this post did.

cdspTotalChannels (1.3.6.1.4.1.9.9.86.1.2.1.1.6), should provide all

channels on a given PRI.

cdspInUseChannels (1.3.6.1.4.1.9.9.86.1.2.1.1.7), should provide all used

channels on a given PRI.

cdspActiveChannels (1.3.6.1.4.1.9.9.86.1.2.1.1.8), should provide all active

channels on a given PRI.

All three OIDs are contained in the cdspStatusTable

(1.3.6.1.4.1.9.9.86.1.2.1). This table is indexed by entPhysicalIndex

(1.3.6.1.2.1.47.1.1.1.1.1), which should correlate to the specific PRI under

entPhysicalTable (1.3.6.1.2.1.47.1.1.1).

cpmActiveDS0s (1.3.6.1.4.1.9.10.19.1.1.4), to get the number of active DS0s

at any moment.

If you wants to check the drill-down detail you can query the

cpmDS0UsageTable (1.3.6.1.4.1.9.10.19.1.1.1).
