This document describes details about the Cisco Log Analysis and Visualization (CLAV) Tool. CLAV is included with Customer Voice Portal (CVP), and provides a ladder diagram for easy visualization of the Session Initiation Protocol (SIP) signalling.

Cisco recommends that you have knowledge of these topics:
The information in this document is based on CVP 9.0(x) and above.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
The trace analysis is done with sequence diagrams.
Steps to create the Sequence Diagram:
Step 1. Identify the CVP Globally Unique Call Identifier (GUCID) for the call you want to trace. In order to find the GUCID, use a standard text editor and search for the ANI and DNIS of the call.
Step 2. Navigate to Start > All Programs > Cisco Unified Customer Voice Portal > Cisco Log Analysis Visualisation Tool.
Step 3. Click Add Files(s)... and select the CVP and ICM logfiles to parse.
Step 4. Click Generate Callflow. The Filter Tab will be displayed with the generated ladder diagrams.
Step 5. Click Next Results until you find the GUCID found in Step 1 under CVP_ICM.
Step 6. Uncheckthe GUCIDs that do not match the GUCID found in Step 1.
Step 7. Click the CVP_IVR tab.
Step 8. Uncheckthe GUCIDs that do not match the GUCID found in Step 1.
Step 9. Click Filter Results. The Sequence Diagram displayed is for your call.
Step 10. Hover over each leg of the diagram to get more information about that leg.
Note: CLAV will readjust the time for your server. If the analysis is done with logs from another CVP server from another time zone, the time will be in your servers current timezone.
Step 11. Click File > Save Image in order to save the diagram to view later.
