Harvest/Grafana/Graphite - Counters for deswizzling?

If I wanted to graph deswizzling (if the counters even existed) how would I do that? Is it possible?

Hi @James_Castro,

 

I am unaware of a counter that shows if the deswizzler is active but if somone finds one it would be trivial to add.

 

The only way I know to get this info is using the wafl scan status command.  So you could write a small script that would SSH to the filer, grab this command output, parse it, and submit graphite metrics with a boolean value of running or not for each volume.

 

I don't plan to code this myself into Harvest (too much collection overhead for not enough demand),  but I was thinking to include an 'extras' folder in Harvest for exactly this kind of thing so if you create it please share!

 

Cheers,
