Sources of Collected Data

The Netcool/Proviso Cisco IP Telephony Technology Pack uses both SNMP and bulk data collection. The technology pack collects performance data from the following sources:

Source of Collected Data

Collection Type

 

 

 

 

PSTN gateway, media gateway

SNMP

 

 

Gatekeeper

Cisco CallManager Server

Each server in the cluster has an SNMP agent

 

 

 

Call Detail Records (CDR)

Bulk

Call Maintenance Records (CMR)

Bulk

Voice quality data

 

 

 

Microsoft performance counter metrics

CDR and CMR data is collected in Cisco CallManager (CCM) environments and Cisco Unified Call Manager (CUCM) environments. The technology pack accesses CDR and CMR data differently in each environment.

The following sections provide an overview of how the technology pack accesses CDR and CMR data in these different environments. A basic understanding of the different access methods will help you when you configure the technology pack.

Collecting CDR and CMR Data with Cisco CallManager

With Cisco CallManager (CCM), the technology pack collects CDR and CMR data through SQL requests to the CallManager Publisher SQL database.
