That worked fine. I can also do what I want to do in PA GUI where I just drill down from filer to wafl to read_io_type down to cache/ext_cache/etc. I think where I'm running into trouble is in the GUI, I have to drill down one more level to get from read_io_type to disk/cache/etc and I don't have to do that for a lot of other counters that I can create views for. Is there a different separator I need to use for the "labels"?
did you find an answer for that ? I have the same question. I would like to monitor a Flash Pool configuration by using the counters wafl:read_io_type:cache, wafl:read_io_type:hya_non_cache, wafl:read_io_type:hya_cache, wafl:read_io_type:hdd but it seems that these counters are not available through the command line.
