Subject: Master wait time metric
Date: Tue, 1 Nov 2016 10:08:49 +1100 [thread overview]
Message-ID: <CAAtdryN4dbaLPZJrgdrDVkdJQXeOpmeOhpC+_u3ZpqpQcQiqJQ@mail.gmail.com> (raw)
Hi Eric / everyone :)
I would like to start graphing how long our master process spends
waiting for worker processes to be available.
This metric will allow us to quickly tell if a unicorn is being
overloaded and allow us to quickly remediate.
Once a minute I want to ask the master process how long it spent
waiting for child processes to become available.
How would I go about getting that metric?
Sam
