This is the fix of following issue.
In the database we store data with host _id of structure -> ip_address:port
For now we save two things to mongo, MIB-REAL-TIME-DATA and MIB-STATIC-DATA. It looks like:
{ "_id" : "127.0.0.1:161", "MIB-REAL-TIME-DATA" : { "1.3.6.1.2.1.1.3.0" : { "value" : "125535155", "type" : "TimeTicks" } }, "MIB-STATIC-DATA" : { "IF-MIB" : [ { "interface_index" : [ "1", "2" ] }, { "interface_desc" : [ "lo", "eth0" ] } ] } }
During first walk operation, firstly host id is being added along with MIB-REAL-TIME-DATA. In case of enricher presence MIB-STATIC-DATA is inserted to the "ip_address:port" structured host id which - we assume - exists.
But in scheduler-inventory.yml host with or without port can be provided. In case user typed bare ip address, in mongo db id was exactly the same:
{ "_id" : "127.0.0.1",
and then in enrichment phase we encountered problem with absent hostname "127.0.0.1:161".
