Finding global average bytes new or change rate

The column you'll be most interested in is the ModSent column. This is the amount of new data actually stored on the server.

You can find a more detailed explanation of the DPN Summary report in the Best Practices guide or in the Avamar Server management best practices Ask the Expert thread:

Re: Ask the Expert: Avamar Server management best practices

I would recommend taking a look at capacity.sh (which you can run from the command line on the Avamar utility node) if you need to get an idea about daily and average ingest rates or the DPN Summary report (which you can generate from the Avamar GUI) if you need something more fine-grained.

See I'm looking at the DPN report but I don't see where you would calculate the change data on this report.

There are

TotalBytes  ModSent, ModReduced, etc.

How would you calculate change data?

Thank you much,

Steven

Hello Smaiello,

You can run capacity.sh script to analyze the data change.

a)  Login to the utility node as the admin user

b)  run /usr/local/avamar/bin/capacity.sh

The top part of the script output shows the date, the amount of new data added, the number of backups taken, the amount of data removed by garbage collection and the net change rate on the system (data added minus data removed).
This section gives you an idea of what is happening on a day by day basis.  You can use this to understand, at a glance, on which days experienced large increases in backup data and how data has been removed in the garbage collection sessions.

It will be very clear if there were an unusual amount (or lack of) backup data or if garbage collection failed to run on a particular day.
