Extract text values (MAX & Average) from rrd file

[RandomWelshBloke]

Does anyone know of a good way to extract text values (MAX & Average) from a rrd file?

The intention is to have a dashboard type page summarising the statistics for a whole network.

e.g. Location, bandwidth, traffic, %utilisation for all sites on one page. Possibly flagging sites that are over 80% utilised for example.

I did look at the rrd xport function but it produces a mental amount of data

Any Ideas are more than welcome

To get the last entry from an rrd, I recommend a command like:

Code: Select all

rrdtool fetch <filename.rrd> AVERAGE --start 0 --end 0

The result should be the time of data gather followed by the result in floating point.

The specific data I am after is the MAX and AVERAGE values printed on the Monthly (2 Hour Average) graph.

The end goal is to have this inserted into a web page.

So far looked at...

The info command gives MAX and AVERAGE values but they are not the same as on the graph other than MAX for the Day graph

The fetch command produces the raw data which would need to be manipulated, and isn't as elegant as I'm sure it can be.

The Perl bindings look like they might do the trick but I can't say I am that familiar with working with them!

Any further ideas? Or links to info!
