We (LogicMonitor) had to add that monitoring recently for a customer, for a very similar issue, where pblocks were exhausted. cifs stat will show max pBlks and Current Pblks, but they are not exposed by snmp or the API, so we had to write a datasource that collects them periodically via ssh.
We did that, but it's dependent on our collection systems (using a groovy/expect type API), so not generically useful to share (and only about 6 lines, anyway.) We could set you up with free trial, though,so you could play with it for two weeks..
As I recall, pblocks were being exhausted, on 7.3.3. Not sure of the resolution....

Is there any way to monitor and alert on pblock utilization via DFM or another monitoring tool? We had an issue recently where CIFS operations ground to a halt that was not resolved until we disabled fpolicy. We believe the entire pblock pool wound up in use and CIFS operations ground to a halt.****
We’re considering running something like this to ensure that CIFS never runs out of pBLKs in the future:****
setflag fp_maxcifsreqs_pblkpercent X****
But we want to determine what the current range is before we make any changes.****
Cifs stat shows the value under Max pBLKs = xxx, but XXX is a number without context, like 1700, and doesn’t help much.****
