Re: High AS400 Storage

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

Running RTVDSKINF and RTVDIRINF regularly are good ideas. The problem 
is, they are not fine-grained enough to detect short-term spikes like 
the OP experienced. disk/HUNTER, Robot Space, and Martin's utility use a 
different approach, probably more like the iNav thing, with additional 
functions when things happen. Of course, you can set commands to be run 
when the monitors exceed thresholds, I believe. disk/HUNTER's thresholds 
include being based on percent reduction of free space - I don't 
remember the threshold types in iNav, but if the latter are some fixed 
point, they are maybe not quite so useful. But anything is better than 
hitting 95% of a sudden at 3am.
