[Logs Overview] Overview component (iteration 1) #191899

weltenwort · 2024-09-02T09:52:16Z

📝 Summary

This introduces a "Logs Overview" component for use in solution UIs behind a feature flag.

🏁 closes: [Logs Overview] Enhanced logs component for solution UIs #190848
🐞 affected by: change_point agg fails with IllegalArgumentException while indexing an array elasticsearch#112805

🏴‍☠️ Feature flag

The new logs overview is currently visible in the "Logs" tab of APM services when the feature flag observability:newLogsOverview is enabled in the advanced settings:

🎨 Previews

In APM UI

In the hosts UI

No log entries

⚠️ Known issues

Since this uses the change_point Elasticsearch aggregation extensively it is affected by change_point agg fails with IllegalArgumentException while indexing an array elasticsearch#112805.

❓ Open questions

See: #191899 (comment)

The change types returned by the change_point agg have some limitations:
- Some of them are hard to interpret (i.e. non-stationary)
- They are sensitive to slight changes in the distribution. A change can flap between a step, a spike and a distribution_change when just a few buckets are different. So it might be advisable to use the change point buckets detected and re-interpret their meaning using the histogram.
It's debatable whether a lexicographical sort order of the change types is a good idea. We might want to come up with more useful sorting weights.
Since the changes types shown in the design mock-ups don't line up with reality the assignment of the colors is unclear. Currently no types' badges are colored.

🕵️‍♀️ Review notes

This adds XState v5 as an additional dependency to start the transition. It can be imported as xstate5. Similarly, @xstate5/react is available.

Release Note

Add experimental logs overview to the observability hosts and service overviews

@patpscal @LucaWintergerst @alex-fedotyev There are a few question that arose while implementing this. I would appreciate your input on them:

Location of the "open in discover" link

The designs show the "open in discover" link to the right of the time picker. In most places that this component would be used, though, the page already has a time picker as part of the page layout. Am I correct assuming that we don't want to duplicate that time picker as it would be confusing to the user? If so, the layout of that part of the page is not under our control and therefore inserting the "open in discover" button in that location would be tricky.

Do we want to look for an alternative location that would work with those pages too?

Colors of the "change type" badges

We need to map the technical change types to the change types shown in the UI. From looking at the design the mapping is not obvious to me, so I would appreciate your input. These are the technical types that we're currently handling in the code:

none: no change, but also not rare
rare: too few documents for a change point detection, but we detect the "first occurrence"
spike / dip: the aggregation detects temporary deviations from an otherwise constant metric
step: the aggregation detects a point in time with different constant metrics before and after
trend: the aggregation detects a trend within the metric with an accompanying correlation coefficient (between time and the metric)
distribution: the aggregation detects a point in time at which the kind of distribution changes
other: the aggregation calls this "non-stationary", but the docs don't specify what it means
unknown: a catch-all in case Elasticsearch returns something we're not prepared to handle

Sorting by "change type"

What sorting criteria do we want to use to sort the "Change type" column by? Just sorting the text of the types mentioned above alphabetically is probably not the most useful. We probably want a custom sort order that reflects what we consider to be "important". Have you put any thought into that or should I come up with something?

alex-fedotyev · 2024-09-05T17:50:27Z

@weltenwort - I am still confused with the description of the change types, trying to map those to the simple terms.
Do you have a sense about change types and examples?
I have been always thinking about the changes in a way of "new pattern", significantly increased rate of existing pattern, significantly decreased rate of a pattern, rare messages.
Could you give me other examples to think about or maybe map the current change type to the ones I proposed?

LucaWintergerst · 2024-09-05T18:32:05Z

I'll leave the open in discover button decision to someone else.

Colors
I think I'll need to get hands on with a draft of it first to make a call here.
This also feels like something we can adjust later on, it should not block us for now.

Sorting
What is our default sort order? Are we using the p_value yet? I'm not sure if this was discussed before. I think we should include it too. It might even make sense for us to convert it into something more readable on a log scale to have a "confidence" column instead of the more cryptic p_value
Sorting on the type of change is a good question. I think alphabetical is not the worst idea, as I might want to check for specific types of changes, so I could for example sort, then scroll to where the first "rare" value begins and then see all other rare patterns next to it

alex-fedotyev · 2024-09-05T20:56:16Z

@LucaWintergerst - default sorting is going to be by "Change at" datetime field which will allow to show the changes above the systemic patterns, and also make it chronological.

I wonder if we should do the opposite and never expose the p-value in any shape, and also make the "Change type" to be just the inline badge and not the column.
This way we will leave true value to be driven by the AI to determine the impact of those changes, which I bet will be better than p-value or change type... in the end, impact can be high for either rare event or a change in the rate of the pattern, everything depends on the content and context.

+        },
+      },
+    ];
+  }

Can you simplify this by using environmentQuery?

hm. not sure. I modeled this after the KQL query used for the old logs stream, which includes both the logs with the given environment and those not having an environment at all. The environmentQuery function doesn't do that. Can you help me understand whether a change in the query semantics would be desirable here?

Amazing work 👏

(Approving based on the iterative improvements that will come and tests are TODO currently).
