NAbox v4 - Dashboard for FC port status and alerting

[dphan85]

Hi All,

I am new in the storage area and with netapp. The team just installed NaBox v4, I notice under one of the Cdot-Network dashboards it has FC information. However I am trying to add the status of the FC itself if it's in an Online/Offline status. I also want to create an alert when a FC go from Online to Offline.

Can someone help me with how I can archive this?

Below is the version that was deployed as part of the installation.

NAbox v4.0.7 (08fc923)
Harvest 24.08.0
Grafana 11.2.0

hi @dphan85

What version of ONTAP are you running?

Do you see the FC ports with Fabric detail panel when you expand the FibreChannel row like shown below? You will need the REST collector enabled since this table is populated with metrics collected from that collector.

The FC ports with Fabric detail has a State row. Does that have the info you need?

ONTAP returns an enum for that field and it will have one of [startup, link_not_connected, online, link_disconnected, offlined_by_user, offlined_by_system, node_offline, unknown]

In terms of creating an alert, try adding something like this to your rules section of your alert_rules.yml.

  - alert: FC port is not online
    expr: fcp_labels{state!="online"} == 1
    for: 5m
    labels:
      severity: "critical"
    annotations:
      summary: "FC port [{{ $labels.port }}] state is [{{ $labels.state }}]"
      description: "FC port [{{ $labels.port }}] state is [{{ $labels.state }}]"

hi @dphan85, Sounds like you're all set coloring the state column with value mappings now? And yes, you want an override for value mappings and cell type=colored background. Minor: You don't have to provide a value for the "Display Text" column, if the value is the same as the column to the left.

There are several places where Harvest uses green for OK, and red for anything else, by using a value_to_num label agent. What you've done works well too.

For your gauge question, take a look at the Security dashboard. The doughnut panels, at the top of the dashboard sound similar to what you're trying to achieve.

Want to contribute your cool panels back to Harvest?

If you end up with changes that you think are useful to everyone, please contribute your dashboard and we'll review and include in Harvest. If you do that, when you export your dashboard, make sure you click the "Export for sharing externally" toggle or ping us for help.

Hi Chris,

Thank you, before we close of the discussion, may i ask one final question.

I decided to separated the count, but I cannot add fcp state ( link_disconnected, offlined_by_user, offlined_by_system,node_offline, unknown) into a single count, is there a specific way to do this?

@cgrinds in regard to sharing dashboard, if I export it and save it, it become a json file, do i need to upload it somewhere on github for review?

@dphan85 You can try something like the following.

(count(fcp_labels{state="link_not_connected"}) or vector(0))
+
(count(fcp_labels{state="offlined_by_user"}) or vector(0))
+
(count(fcp_labels{state="offlined_by_system"}) or vector(0))
+
(count(fcp_labels{state="node_offline"}) or vector(0))
+
(count(fcp_labels{state="node_unknownoffline"}) or vector(0))

Regarding the dashboard, you have two options for submitting updates:

1. Open a pull request by updating the relevant dashboard at NetApp Harvest Pull Requests.
2. Alternatively, you can email the JSON file to us at [email protected].

@rahulguptajss , thank you.

I just tried this and i think it work. I remove the "link_not_connected" as we do not need this to be reported.

Thanks Everyone for your support.
