|Title||winperf_if: Fixed discovery of network interface alias|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Incompatible - Manual interaction might be required|
While parsing the winperf interface section only trailing spaces were stripped off. There may also be leading spaces. Without cutting them off additional information like NetConnectionID, GUID or MAC address of the interfaces were not found. In this case the instance name of the interace was used as alias (fallback) instead of the NetConnectionID.
Now if one has configured Use alias in the Network Interface and Switch Port Discovery ruleset new services may be discovered and old ones will be vanished. In order to obtained the already used iterface names please use Use description in the Network Interface and Switch Port Discovery ruleset.
