Hello Elastic team,
I'm actually working on SLI/SLO visualization on Kibana.
My request is a bit complexe :
I need to visualize the remaining error budget using this formula :
EB = 436 minutes
IF (not status = "500" or latency \< 2) / (status : \*) \< 0.98 :
THEN Remaining EB = EB - 1
And I need to Show the value on a Metric.
Is there a way to do so ?

I'll give more details in this comment.
So basically I have a huge amount of logs on my elastic,
In a first step I calculate the ratio (number of requests not 500 and number of requests \< specified latency) / total number of requests which I define as availability ratio.
In a next step we define a remaining error budget = 436 minutes.
Last step : If availability ratio (during 1 minute time-window) \< 0.98 we consider this minute as burned or HS so we do error budget = error budget - 1
My main objective is to keep track of this remaining error budget

@Marius_Dragomir want to take a look at this? Thanks!

Hello Again Elastic community,
So basically I found a solution. Yet, I'm not sure if it's the best solution.
- Going through a transformation

- In a second step I add painless scripted field (Field name : SLI)
> emit ((doc['latency.filter'].value + doc['500'].value)/doc['now.value\_count'].value)
Finally I create a metric with a formula ( 436 - count () ) While filtering on SLI \> 2%
