Feature request for NAS connections and iscsi sessions counts metric

[summertony15]

Describe the solution you'd like
NetApp has the limitation of Maximum number of connection -- NAS per node,
Here is the HWU example: https://hwu.netapp.com/Controller/Index?platformTypeId=30310846&platform=29266985&os=34942206#none

And here is the description: Maximum number of NAS (SMB and NFS) TCP connections that a node can support

Also, we have a maximum number of iSCSI sessions,

We want to monitor these two value, in case they reach the limits.
I need both of them, thanks
Best to have both ZAPI and REST templates.

Update the request which needs two values mapping to the values shown in HWU as the description.

@summertony15

Could you share the time taken and the number of records returned by the following commands in the relevant environment you want to track?

Make sure to replace USER, PASS, and CLUSTER_IP with the appropriate values.

1. NFS Connected Clients (without records):

   curl -w "Total time: %{time_total}\n" -s -k -u USER:PASS 'https://CLUSTER_IP/api/protocols/nfs/connected-clients?return_records=false'

2. NFS Connected Clients (with records):

   curl -w "Total time: %{time_total}\n" -s -k -u USER:PASS 'https://CLUSTER_IP/api/protocols/nfs/connected-clients?return_records=true&fields=client_ip,node.name,protocol,server_ip,svm.name,volume.name'

3. iSCSI Sessions (without records):

   curl -w "Total time: %{time_total}\n" -s -k -u USER:PASS 'https://CLUSTER_IP/api/protocols/san/iscsi/sessions?return_records=false'

4. iSCSI Sessions (with records):

   curl -w "Total time: %{time_total}\n" -s -k -u USER:PASS 'https://CLUSTER_IP/api/protocols/san/iscsi/sessions?return_records=true&fields=tsih,target_portal_group,initiator.name,isid,svm.name'

Thanks.

Hi @rahulguptajss

[rahulguptajss]

Thanks @summertony15 . So, if we export NFS and iSCSI connection counts at the cluster level, will that be good?
CIFS (node_cifs_connections) is already present which includes all relevant protocols.

[summertony15]

I think node level is better, since the limitation is by node.
We can count the cluster level, by sum up by each node

[rahulguptajss]

Sure Thanks.

ISCSI seems to be at svm level. I don't see any node information in API api/protocols/san/iscsi/sessions.

@summertony15 Could you also run the commands shared in this comment on an ONTAP system with a large number of connections?

The reason for this request is that we want to measure the time taken for these calls.
