During the ops-perf sync up meeting last Wednesday, we looked at the dashboard for the getLagTimes data, https://grafana.wikimedia.org/dashboard/db/mediawiki-mysql-loadbalancer and it wasn't sure whether or not it is working properly due to the graphs being almost entirely empty.
This task is to verify the script works, is enabled in production, and is making its way to statsd/Graphite/Grafana correctly.
