About this task

InfiniBox provides a way to query which clients are connected to a specific filesystem, similar to the host-side showmount -a command.

Note

Only live IOs can be queried. The query does not display mounted filesystems that have no activity.

How to query for NFS clients and the filesystem they are using

The NFS IO can be filtered by either a filesystem or an export.

From InfiniShell

Filtered by a filesystem

metrics.nas.fs.show fs=fs1

Filtered by the source IP

First, look up the incoming clients, using this command:

metrics.nas.source_ip.top fs=fs1

The output looks like this:

System ibox1150
Top NAS source IPs in system by OPS

Collecting data...
System ibox1150
Top NAS source IPs in system by OPS

SOURCE IP OPERATIONS THROUGHPUT LATENCY
172.16.88.152 210 13 MiB/sec 0.175 ms

Once we have a list of NFS Client IPs, we can show the detailed performance for that NFS client.

metrics.nas.source_ip.show source_ip=172.16.88.152

The output looks like this:

System ibox1150
Source IP '172.16.88.152' NAS performance in system
 
Collecting data...
System ibox1150
Source IP '172.16.88.152' NAS performance in system
