I have a set of 6 filers in Operations Manager / Performance Advisor. All 6 of them show a green light in the "Data Collection Status" column, but 1 of them doesn't actually seem to have any data. all 19 Object Types in the list (nfsv3, disk, etc) show a Used Space of 768 bytes, and the charts/graphs under the View are all blank. The other filers show a Used Space of anywhere from 768 bytes for some object types (presumably, things that don't get used) up to 10MB for others.
I can collect client statistics for it... that seems to work fine. But the main stats/counters seem to have no data. This happens for that filer itself, as well as the aggregates and volumes within it.
Any ideas as to what might be wrong, or where I might look for diagnostic info?

Nope... no dice. Realtime view shows no data as well. "Storage System Summary View" graphs just have no data plotted on them. Other views like Top Volumes say "No data is currently available for chart".
"dfm host diag" shows that it has snmp connectivity, and I can ssh to the filer from the DFM host as well... so it seems not to be a firewalling issue.
"dfm perf data describe -v system" shows plenty of enabled counters, but the oldest and newest record fields are blank, number of records is zero, and used space is 768 bytes. Max records is 525600.
"dfm perf data retrieve -V "System Basic -d 6000" shows no output... so it's not just a graphing problem, there really seems to be no data to plot.

Not sure why this is, but I would start by going into the Operation Manager GUI, select the physical filer (eg Member Details -> Physical Systems -> filer), then select 'Diagnose Connectivity'. Check everything looks OK there, in particular at the end under 'Performance Advisor Checklist'

Connectivity looks fine:

All the other DFM data (volume capacity, aggregates, etc) is being collected, alerting works fine, protection manager works. Its only the performance data that doesnt seem to be collecting. You can see that the counters are enabled, but they dont contain any records, as the previous poster said.

did you get anywhere with this? I ahve the same issue. Everything is enabled, everything looks fine but for some reason it's not collecting the volume stats for some filers. It seems to collecting everything else ok

talking to myself, but bumping options perf.dblade_zapi.buf_limit seems to have fixed the issue. Please check this though http://support.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=472940 as it's potentially dangerous
