Monitoring NFS/SOFS Ingestion

Zenko implements an NFS feature that ingests the NFS file hierarchy that the RING’s Scale-Out File System (SOFS) projects. For this release, the only available metrics for NFS/SOFS ingestion operations reside in log files. SOFS metadata ingestion runs on a cron schedule, and users can make a query against Cosmos on the kubectl location to discover how and when scheduled NFS activities have been executed.

To find the relevant Cosmos pods, enter:

$ kubectl get pods  | grep "rclone"

nfs-options-cosmos-rclone-1555329600-7fr27                    0/1     Completed   0          7h
nfs-options-cosmos-rclone-1555333140-bb5vf                    1/1     Running     0          1h

Use this information to retrieve the logs with a command formatted as follows:

$ kubectl logs -f {{location}}-cosmos-rclone-{{hash}}


$ kubectl logs -f my-location-name-cosmos-rclone-84988dc9d4-9dwjl
