Creating A System Snapshot - Cisco TelePresence Administrator's Manual

The VCS continually logs all system activity to a unified log file. The diagnostic logging facility works by
n
extracting a portion of this unified log. On busy systems the unified log file may become full over time and
will discard historic log data so that it can continue logging current activity. This means that all or part of
your diagnostic log could be overwritten. The system will warn you if you attempt to download a partial
diagnostic log file.
The diagnostic log will continue logging all system activity until it is stopped, including over multiple login
n
sessions and system restarts.
The various log level settings cannot be changed while a diagnostic log is in progress. The log levels are
n
reset to their original values when you stop the diagnostic log.
Diagnostic logging can only be controlled through the web interface; there is no CLI option.
n
Clustered VCS systems
Diagnostic logging can also be used if your VCS is a part of a cluster, however some activities only apply to
the "current" peer (the peer to which you are currently logged in to as an administrator) :
Each cluster peer maintains its own unified log, and logs activity that occurs only on that peer.
n
The start and stop logging operations are applied to every peer in the cluster, regardless of the current peer.
n
Marker text is only applied to log of the current peer.
n
You can only download the diagnostic log from the current peer.
n
To add markers to other peers' logs, or to download diagnostic logs from other peers, you must log in as an
n
administrator to that other peer.

Creating a system snapshot

The System snapshot page
can be used for diagnostic purposes. The files should be sent to your support representative at their request
to assist them in troubleshooting issues you may be experiencing.
You can create several types of snapshot file:
Status snapshot: contains the system's current configuration and status settings.
n
Logs snapshot: contains log file information (including the Event Log, Configuration Log and Network
n
Log).
Full snapshot: contains a complete download of all system information. The preparation of this snapshot
n
file may take several minutes to complete and may lead to a drop in system performance while the
snapshot is in progress.
To create a system snapshot file:
1. Click one of the snapshot buttons to start the download of the snapshot file. Typically your support
representative will tell you which type of snapshot file is required.
The snapshot creation process will start. This process runs in the background. If required, you can
l
navigate away from the snapshot page and return to it later to download the generated snapshot file.
When the snapshot file has been created, a Download snapshot button will appear.
l
2. Click Download snapshot. A pop-up window appears and prompts you to save the file (the exact wording
depends on your browser). Select a location from where you can easily send the file to your support
representative.
