Hello,

I got often this logstash warning.

```auto
[2024-07-30T13:39:05,486][WARN][logstash.filters.throttle][main][34074a72c3b9ba7bd86762d4ae78ed3b6314e6bcc23a9a4cf6c5707484cc7c58] filters/LogStash::Filters::Throttle: timeslot disappeared, increase max_age to prevent this.

```

I try already to increase max\_age time to minimum of the double of the duration time, without any effect.  
My problem is, I don't know which "throttle" makes this warning and my logstash config has over 100 throttles.  
It is possible to save/mark the event when it has a warning or an error?  
Or do you have any other ideas to debug/solve this problem?

Thanks for your help  
Thomas

Have you tried adding an [id](https://www.elastic.co/guide/en/logstash/current/plugins-filters-throttle.html#plugins-filters-throttle-id) to each one of your throttle filters?

This is used to identifies the filter, when you do not add an `id` logstash generates one, if I'm not wrong is this hash here:

> [2024-07-30T13:39:05,486][WARN][logstash.filters.throttle][main][**34074a72c3b9ba7bd86762d4ae78ed3b6314e6bcc23a9a4cf6c5707484cc7c58**]

I add erverywhere an ID and it works fine. Now I understood this feature. So cool. 🙂

I found my throttle, which makes this problem.

Thank you.
