  • what is the best way to monitor read requests coming into a slave?

    #1
    We're working on switching our application code to send reads to a slave (or proxy) so its a gradual process. What's the best way to monitor the activity on the slave to make sure that the reads are coming through?

    Thanks

    1) Enable the general query log; or
    2) Enable the slow query log with long_query_time=0 if you have mysql5.1 or a 5.0 Percona build; or
    3) Watch TCP traffic (mk-query-digest is handy for this).
