I am unable to convert a field, that I am generating using 'kv' plugin, from string to integer. Here is the snippet of the config:
> filter {
> kv {
> allow\_duplicate\_values =\> false
> value\_split =\> "="
> }
> mutate { convert =\> { "elapsed" =\> "integer" }}
> }
Any insight is much appreciated.

Hi,
Have you tried using the mutate filter to convert to a string to an integer:
[https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-convert](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-convert)

That's exactly what I am trying to use (see the code snippet), however to no success.

Is this an LSF or an LS question?
