[RAC] [Metrics UI] Link inventory alert to the specific inventory item

[mgiota]

📝 Summary

In the Alerts Observability table alerts generated from the inventory rule type link at the moment to the default inventory metrics page '/app/metrics/inventory'. The link that needs to constructed depends on the node type information (pod, container or host) and looks like:

• app/metrics/link-to/pod-detail/pod123456abcdef
• app/metrics/link-to/container-detail/container123456abcdef
• app/metrics/link-to/host-detail/227453131a17

✔️ Acceptance criteria

• The alerts index should contain the node type,
• Use the node type from the index to construct the link in the browser.

Good issue description, thanks. A few thoughts on how to actually index the node type:

From what I understand the intention behind the RAC schema is to index the information into ECS fields in the alerts document whenever possible to allow cross-docment correllation of these alerts with the other data sources. So in this case that would mean depending on whether the node is a host, container or pod we'd index into host.hostname (or host.name?) or container.id. The link formatter can then check for existence of these fields without extra decoding, because they are already part of the ECS schema. I don't know what to do about the kubernetes.pod.id, which is not part of the official ECS mapping. 🤔

Looks like kubernetes would be identified using

{
  "orchestrator.type": "kubernetes"  
}

but I don't see a way to identify the specific pod.

@afgomez this is blocked on the RFC work you're doing, right? I think we should say this won't make 7.16

@mgiota is this issue still relevant or can it be closed?

This ticket is old and probably deprecated, feel free to reopen it if it is still relevant and needed.
