# Parse output from mysqlbinlog
# mysqlsla cannot directly parse binary logs
mysqlbinlog LOG │ mysqlsla –log-type binary –
# Parse a microslow patched slow log
mysqlsla –log-type msl LOG
# Replay a replay file
mysqlsla –replay FILE
# Parse a user-defined log specify its format
mysqlsla –log-type udl –udl-format FILE
# Let mysqlsla automatically determine the log type
mysqlsla LOG
报表：
