Avamar client logging Informational levels

When diagnosing an Avamar client issue it helps to have sufficient, but not too much detail in the logs.

When running a manual backup using the Avamar Administrator user interface, the user can select the level of verbosity. 
 
Alternatively, an entry can be made to the client avtar.cmd file.

No informationals

Little information is provided.

• Backup start time and time zone
• Avamar client version and platform
• avtar launch parameters
• Avamar server connection 
• Warnings or errors
• Final closure statement with the number of errors

An example of a backup log with NO informationals is attached "backup log with NO informationals.txt"

Many informationals

avtar.cmd contains.
avtar log file reports

<flag type="pulldown" pidnum="3001" value="2" name="informationals" />

This is the default setting when running an Avamar backup. 
In addition to the information shown with 'No informationals' we see.

• Workorder details including target list, directives, and backup parameters
• Client backup volume details
• Inclusion and Exclusion rules including system exclude statements and custom rules
• Client-server connection information
• Avamar server version and name
• avtar cache file information
• Detailed VSS snapshot information
• Backup label and summary
• Status update information

All informationals

avtar.cmd contains.

--informationals=3

avtar log reports

<flag type="pulldown" pidnum="3001" value="3" name="informationals" />

Similar to Many informationals, but with the addition of the following

The backups carried out for testing purposes and whose logs are attached to this article are for a simple 10 file dataset.

You can also change the logging level by setting the "Informational" level per client using avtar.cmd

By default the Informational logging is enabled and set to "Many Informationals". This is set at the dataset level. We can also enable Informational logging just on one backup client using the flag:
