How to view the error log for any specific instance

There are many ways but I prefer following method. Take a scenario when you want to find the error log when the DB was put in a single user mode.
CREATE TABLE #Errorlog (Logdate Datetime, Processinfo VARCHAR(20),Text VARCHAR(2000))
INSERT INTO #Errorlog
EXEC xp_readerrorlog
SELECT * FROM #Errorlog
WHERE Text Like ‘%SINGLE%USER%’
