How service mapping works

In this section, lets explore and see how Service Mapping works.

  1. For every discovery request, service mapping selects MID Server, by default service mapping selects the MID Server whose IP ranges matches the IP in the discovery request. If there is not a match service mapping selects the default MID Server.
  2. Service mapping creates a discovery request for the IP address of the entry point. It then writes the request in the (ECCExternal Communication Channel (ECC) queue and assigns an MID Server to the request.
  3. The MID Server passes information on the discovered CI, its attributes, and connections to the ECC queue.
  4. The MID Server checks the ECC queue and retrieves the discovery request assigned to it.
  5. The MID Server starts running identification sections of the pattern to find the match for the entry point. When the identification section matches the entry point, the pattern discovers a CI.
  1. The MID Server starts running connectivity sections of the pattern to find outgoing connections of the newly discovered CI.
  2. Service mapping checks the ECC queue and receives information on the newly discovered CI.
  3. Service mapping writes the information into the CMDB and adds this CI to the business service map.
