Monitoring using mmpmon

You can use mmpmon to monitor AFM to cloud object storage.

Complete the following steps to enable the Performance Monitoring tool and query data.

To reset some statistics on a gateway node.

# echo "afm_s reset" | mmpmon
# echo "afm_s fset all" | mmpmon

Reset all statistics.
```
# mmfsadm afm resetall
```
Check the statistics.
```
# echo afm_s | mmpmon -s -r 0 -d 2000
```
This command shows statistics from the time the gateway is functioning. Every gateway recycle resets the statistics.

The following example is from a gateway node. The example shows how many operations of each type were run on the gateway node.

~# echo afm_s | mmpmon
