I need to parse the following line:  
`2016-12-02 11:54:03,107 Tests run: 2344, Failures: 0, Errors: 1, Skipped: 14, Time elapsed: 1,480.535 sec <<< FAILURE! - in com.werum.pasx.servicetests.ebrequipment.TestSuiteEbrEquipmentBf`

Here my grok pattern:

```
grok {
	  break_on_match => true
	  match => ["message", "(?m)%{TIMESTAMP_ISO8601}\s*%{TIMESTAMP_ISO8601:logdate}\s.*INFO\s.*?Time elapsed:\s(?<duration>[0-9.,+-]+)\s*sec\s.*com\.werum\.pasx\.%{DATA:probe}(\s|\n)%{GREEDYDATA:msg}"]
	  match => ["message", "(?m)%{TIMESTAMP_ISO8601}\s*%{TIMESTAMP_ISO8601:logdate}\s.*INFO\s.*?Time elapsed:\s(?<duration>[0-9.,+-]+)\s*sec\s.*com\.werum\.pasx\.%{GREEDYDATA:probe}"]
	  match => ["message", "(?m)%{TIMESTAMP_ISO8601}\s*%{TIMESTAMP_ISO8601:logdate}\s%{GREEDYDATA:msg}"]
	  match => ["message", "(?m)%{TIMESTAMP_ISO8601:logdate}\s%{GREEDYDATA:msg}"]
	}

	mutate {
	  convert => ["duration", "float"]
	}

```

It works, if the numbers follwing "Time collapsed:" don't contain a comma as delimiter. In my example duration contains 1 after mutating.  
Any idea, how I can get the correct number ?

Use gsub in mutate filter before mutate convert to get rid of the comma? [https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html)

Thank, works, but only if I place gsub and convert in different mutates

```
mutate {
gsub => [
  # remove all comma 
  "duration", ",", ""
]
add_field => {
  "org_duration" => "copy from %{duration}"
}
}
mutate {
	convert => ["duration", "float"]
}

```

Any idea why?  
It's not essential, but I'd like to know the reason 🙂

Next inconsequential detail:  
Kibana shows the number with comma again 😕

Known issue [Each mutate must be in its own code block · Issue #27 · logstash-plugins/logstash-filter-mutate · GitHub](https://github.com/logstash-plugins/logstash-filter-mutate/issues/27)

You can change the display format of number fields in Kibana. Go to `Settings > Indices > <your_index>` and change the field format to your need.
