NAS mount point slowness due to Network Issue

If server is using NAS shared file system , Then at a times if the mount point is very slow the communication between Server & NAS mount point will fail and eventually will impact the application / outage of the environment.

Check below listed to verify if there is an issue with NAS mount point:

1. Run df -k to get mount point that you wanted to check
example : df -k 
10.200.114.32:/apps_ct   1056325248 146003040 910322208  14% /apps

3. tracerounte  <ip/hostname of the directory on NAS>
     example: traceroute 10.200.114.32
  
 4. If the trace route is taking too much time then it is the problem between server and NAS mount point

5. SAR 5 5  can also reveals the network issue between server and mount point.
