> * 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)
