Some comments and suggestions.
| Monitor collection activity and processing status to confirm uploads, understand analysis timing, and troubleshoot failures. The status concepts in this guide apply to both collector client jobs on the [Finished Jobs Log](#finished-jobs-log) page and manual uploads on the [File Ingest](#file-ingest) page. | ||

| See [Alerts](/manage-bloodhound/alerts/overview) to learn about configuring webhooks for collector offline events. |

collector offline is the name of the alert.
Maybe we should make it a bit more clear.
either "collector offline" or Collector Offline would indicate this a bit better.

I see what you mean and I'm happy to try one of your suggestions.
But that's got me thinking, do we need to distinguish between "alerts" and "events" or are they synonymous as far as our implementation is concerned?
Looking at some of the relevant API endpoints, it looks like we're using the compound noun "alert events". I suppose I should normalize the docs accordingly. Same for "alert webhook".

Actually, the UI is probably the better source to go by:
- Webhooks
- Event triggers (perhaps simplify as events in general prose)
I'll normalize generally on the UI.

I agree with Webhooks and Events
But the way I see it the Events (from the Log) and Non Events (something not happening for X minutes) can trigger Alerts.
So the event is what happens in the system and the alert is what we send via a "channel". Right now we only have one type of channel: Webhooks

The text of the Beta Access do not make sense to a non SO person imho.
This is Called "Early Access" in the app and until we change the wording in the app I would not use Beta to describe Early Access.

I can change it back to what it was before the request to change it in #385. Specifically, these comments:
- DOCS-23: Findings table view for Attack Paths #385 (comment)
- DOCS-23: Findings table view for Attack Paths #385 (comment)
But I'm also using <Badge color="yellow">Beta</Badge> in a few places that will need to be changed.

I am in favor of reverting, but we can have a discussion with Rich/Loki. I don't want to go back and forth between the terms. We should all agree.

| Alerts help you detect interruptions in data collection and send that information to the operational tools your team already monitors. When BloodHound Enterprise detects that a collector is offline, it can send a signed event to a generic HTTPS webhook so your team can begin investigating without first opening BloodHound Enterprise. |

Alerts informs you of important things happening in your tenant/environments.
Collector Down is only the first event we're triggering on.
In the future we could/will add "New Critical Findings", "New User Created", etc.
Also, the next Phase is to add other delivery method(s). Email is the next one planned for Phase 2, and In-App was also discussed (but more likely Phase 4 or 5 as it's a bigger feature all together)
There was a problem hiding this comment.
I deliberately worded this based on what's available in beta with the expectation that as more events and alert mechanisms become available the docs would evolve.
It's not always a good idea to make forward-looking statements in the docs, but I suppose we can make an exception for a beta.

| Alerts currently support one event: **Collector Offline**. You configure where BloodHound Enterprise sends the event in **Delivery**, configure when it sends the event in **Rules**, and review the result in **Event History**. |

This is perfect, I would just add that it support only one delivery method: Webhook
But you can configure multiple Webhook (ex: To send to different Slack/Teams Channels)

I think I cover that in configure.mdx, but I can work it in here as well.

| ## Create a rule |
There was a problem hiding this comment.
Should it be Rule instead of rule?
There was a problem hiding this comment.
No, all other headings use sentence case instead of title case. I know we have inconsistent use in other pages (lots of title case), but sentence case is the preferred style for the docs repo.
Stay tuned for an automated check to enforce style in a future PR 😎

Just like the Event Trigger, we could mention that only 1 is avaiable

Is the word "representative" too engineeringy ?
I know it's also used higher up.

Maybe? I'll consult a thesaurus for an alternative and do a global find/replace.

| Failed deliveries can arrive more than once, including after a manual retry. Delivery is not strictly at least once: if BloodHound Enterprise sends an event but cannot record the success, it does not automatically retry that attempt. | ||

This sentence is confusing. I'm not sure what we are trying to convey.
Especially this bit: Delivery is not strictly at least once:

Summary
This pull request (PR) adds net new pages for the Alerts feature that will be available as a beta in v9.7.0.
I've deliberately omitted screenshots for this initial draft. I was more concerned with getting the general shape of the docs in place first.
