> * metastorage.availablePeers is an int gauge, reports number of available
> members of the MG voting set (this is calculated based on the current logical
> topology)
> * metastorage.available is an int gauge, its value is 1 if the MG majority
> is available, 0 otherwise (this is detected based on a periodic check for
> whether MG can execute commands)
> * schemaSync.waits is a histogram of times of all waits (in milliseconds,
> for last 10 minutes) caused by schema synchronization (might indicate that
> something is wrong with the Metastorage)
