Collect Frontent WWPN Information

[LukasBr1337]

For our internal PerformanceWarehouse we need the WWPNs from the front end ports. Would be great to implement that. We want to have a full view from Host to Storage in Grafana.

Hi Lukas,

I agree this is a good request.

This information is available in the Purity API in GET /ports. That URI has not been implemented in the OpenMetrics exporter.

@LukasBr1337 do you have any suggests on Semantic Conventions for this new suggested info metric? (eg for purefa-metrics.md ) or any suggestion what this metric output should look like?

[LukasBr1337]

for other vendors we know it like that -> /23:43:00:02:ac:02:5c:07/3:4:3/iops" 3:4:3 would be in this case Node:Slot:port

Here's a POC that I've built in my environment

I went ahead and wrote it for all port types. NVMe, iSCSI, and FC. My testing results are below.

Would this fit your requirements @LukasBr1337 ?

Note, none of the names, descriptions..etc are finalized - just demonstrating for now.

looks pretty good for us :)

only request... lower cases would be great :D

[sdodsley]

@LukasBr1337 FlashArrays produce their WWNs in uppercase and we are just directly reporting what the array sends us. Is there a specific reason why you would prefer them lowercase?

[sdodsley]

Alos, we currently report the hosts WWN information in uppercase as well, so moving to lowercase would create a misnatch of cases across different responses.

[LukasBr1337]

From other vendors and from the brocade switches we are getting them in lowercase so it would match better like that

[chrroberts-pure]

@LukasBr1337 It is common for observability platforms to convert all tags to lowercase - such as this example in Datadog. This would convert the tags to lowercase like you are requesting
