Our new check PerfAggregate measures various performance counters per aggregate. Currently, the following counters can be monitored:
- aggr_throughput (B/s)
- latency (µs)
- read_data (B/s)
- total_transfers (/s)
- total_transfers_hdd (/s)
- total_transfers_ssd (/s)
- transmit_failure (-)
- user_read_blocks (/s)
- user_read_latency (us)
- user_write_blocks (/s)
- user_write_latency (us)
- write_data (B/s)
We are open to your suggestions on additional counters that we could add. A description for each counter of a filer can be displayed using the getter and respective switch ‑‑discover=counters.```
$ ./get_netapp_perfdata.pl ‑H your_filer ‑o aggregate ‑‑discover=counters
Filer Level
-----------
In order to monitor these values on a filer level, we've also included the switch `‑‑math=total|average`, which is already in use in PerfVolume. This way, one can calculate sums and averages for all aggregates. Two examples can be found on our [help page for PerfAggregate](https://netapp-monitoring.info/en/help/PerfAggregate.html#A1). This plugin is now available and is part of our **unstable (beta) release 3.9.2\_08.** We are planing to release the stable release 3.10.0 in mid-December.
