Device Logging
Device Logging
The Device Logging area on a conference station’s web page provides information you can use to help
monitor and troubleshoot the conference station. It includes debug and error messages received on the
conference station that might be useful to Cisco TAC if you require assistance with troubleshooting.
To display device logs, access the web page for the conference station as described in the
“Accessing the Web Page for a Conference Station” section on page 8-2, and then click the
Device Logging hyperlink. In the File Download dialog box, click Open to view the device logs, or click
Save to save the logs to a specific location.
Streaming Statistics
A conference station can stream information to and from up to three devices simultaneously. A
conference station streams information when it is on a a call or running a service that sends or receives
audio or data.
The Streaming Statistics area on a conference station’s web page provides information about the streams.
Most calls use only one stream (Stream 1), but some calls use two or three streams. For example, a
barged call uses Stream 1 and Stream 2.
To display the Streaming Statistics area, access the web page for the conference station as described in
the
“Accessing the Web Page for a Conference Station” section on page 8-2, and then click the
Streaming Statistics hyperlink.
Table 8-4 describes the items in the Streaming Statistics areas.
