详细使用方法：
# Basic operation: parse a MySQL slow or general log
mysqlsla --log-type slow LOG
mysqlsla --log-type general LOG

# 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：
[root@node01 testing]# mysqlsla SRVR00-slow.log
