Subject:InnoDB Spin Stats Not Reported?
View as plain text  
MariaDB [(none)]> status
Server version:         5.1.44-MariaDB-mariadb75 <--not the newest, but...

MariaDB [(none)]> show innodb status;
Mutex spin waits 68, rounds 1930, OS waits 64 <--something

MariaDB [(none)]> show global status like '%spin%';
Empty set (0.00 sec) <--nothing?!

Why are InnoDB spin rounds, spin waits, OS waits not reported? I rewrote a
Ganglia plugin to graph stats and assumed I didn't need to parse "show
innodb status" anymore. Should I revisit my assumptions?
