The parameters you can use with XP_READERRRORLOG are mentioned below for your reference:

1. Value of error log file you want to read: 0 = current, 1 = Archive #1, 2 = Archive #2, etc...
2. Log file type: 1 or NULL = error log, 2 = SQL Agent log
3. Search string 1: String one you want to search for
4. Search string 2: String two you want to search for to further refine the results
5. Search from start time
6. Search to end time
7. Sort order for results: N'asc' = ascending, N'desc' = descending

By default, there are six archived SQL Server Error Logs along with the ERRORLOG which is currently used. However, it is a Best Practice to increase the number of SQL Server Error Logs from the default value of six. Hence I recommend that you read this tip Increase the Number of SQL Server Error Logs.

Also, if you are using endpoints, such as Database Mirroring these will show up as ports as well. The way to differentiate the ports being used is to look at the data where the ProcessInfo column equals 'Server' to find the port used for the database engine.
