Hey there,
I am using logstash to write data from my mssql database to elasticsearch.
For whatever reason logstash transfrom the db-field "Duration" which contains values in the style of: "00:00:45.4388525" into this: "2020-03-13T00:00:02.609Z".
I have tried all kinds of input-plugins, filter-plugins, changed the sql statement, transformed the db-field so it would not contain the ":", created a custom index-template.
The closest I got was using this filter:
filter {
mutate {
convert => { "duration" => "float" }
}
}
and changing the statement so the field would not contain ":".
In addition I mapped the field as "long" in the index-template.
This is the only way that even returned a number that could be formatted as a duration in kibana.
All the other methods I tried returned either strings or dates.
Does anyone actually know why logstash is auto transforming this number? I just want to be able to use the field-value as a duration in ms.
regards & thanks in advance.
