Hi,

I have a data with following field name and values:

\<Metric\_1\> \<Metric\_2\> \<Metric\_3\> \<Server\_Name\>

1-01-2017 10 20 30 Sever\_1  
2-01-2017 50 60 70 Server\_2  
.  
.  
etc.

In the mapping I declare "Server\_Name" field as 'Keyword' to use it as a "Split Data" and "Key Field" value.

I read in the documentation that the detector values can also be used as influencer value. In that case, I would like to use "Metric\_1" value as an influencer here. I have it assigned to "long" data type. Here, I want to know how to use this detector value as an influencer value. Can a value with integer values be used as an influencer? Could you help me with this?

Thank you.

No - influencers are meant to be for fields that are categorical - and are useful in identifying instances of entities that are "to blame" for the existence of the anomaly (a particular server name, a user name, etc.)

Any field in `by_field`, `partition_field` or `over_field` in the detector are good candidates for influencers.

Any field that is not part of the detector needs to be a categorical field, (a `keyword`).
