Hi Team,

I'm trying to create a timelion visualisation for the delta of the 'logstash\_stats.events.out' field from the system index .monitoring-logstash\*. The problem is that nothing is displayed for this index when I create the visualisation.

If i use this query which seems fairly simple, I get no data

```auto
.es(index='.monitoring-logstash*', metric='max:logstash_stats.events.out', timefield='@timestamp')

```

The query I'm trying to get working eventually is

```auto
.es(index='.monitoring-logstash*', metric='max:logstash_stats.events.out', timefield='@timestamp',).subtract(.es(index='.monitoring-logstash*', metric='max:logstash_stats.events.out', timefield='@timestamp', offset='-1m'))

```

Is this a limitation of Kibana not being able to use the system index in the timelion or am I doing something wrong?

Thanks  
Jason

The timefield should be just `timestamp`. Try that and see if it helps
