    master/slave_shutdowns_completed
    
    These are slaves which were not heard from despite the slave-removal rate limit, and have
been removed from the Master's slave registry. This is essentially the slave failing its health
check.

    These are slaves that are able to cleanly re-join the cluster and connect back to the
master after the master is disconnected.



docs/metrics.md
<https://reviews.apache.org/r/33241/#comment132921>

    These are slaves which are being removed for various reasons, including Maintenance. This
metric will be broken out for https://issues.apache.org/jira/browse/MESOS-2485



docs/metrics.md
<https://reviews.apache.org/r/33241/#comment132923>

    Slaves which have failed their health check and are scheduled to be removed. They will
not be immediately removed due to the Slave Removal Rate-Limit, but master/slave_shutdowns_completed
will start increasing as they do get removed.



docs/metrics.md
<https://reviews.apache.org/r/33241/#comment132914>

    This happens when the slave removal rate limit allows for a slave to reconnect and send
a PONG to the master before being removed.
