We are developing a custom Observer that should obtain topology data by querying a custom CMDB.

Is there any document that guides how to develop a custom Observer?

The idea is to use the concept of matchTokens to associate alerts with topology data.

How can we include the matchTokens information in the topology data generated by Observer?

We are looking at two alternatives for Observer development: File observer and Rest API Observer.

Initial tests with File observer were promising but it is not including matchTokens information.

Thanks in advance for any suggestions.

Hi,

once you define vertex in file observer input, it has property "matchTokes". 

here is example : 

V:{"_operation":"InsertReplace","uniqueId":"NCIM:%s","entityTypes":["router"],"_status":[],"matchTokens":["%s"],"name":"%s","tags":["Service"]}

The suggestions were important and helped to clarify my doubts.

I thank everyone.
