We have athe latest install of Netapp Harvest on CentOS 6.6. We are using FILER for performance data. We can collect data ok and the pollers are running ok but all graphs are not showing any data since 8th Feb. I have checked connectivity / login /certs and run /opt/netapp-harvest/util/perf-counters-utility successfully so data is available. I cannot see any errors in the logs. Any ideas where else i could look?
