Right now, only multi-instance misc hosts have the replication lag check.
Review other replication related check and add them to all misc hosts, as they should exist on either multi-instance or non multi-instance hosts.
Check also the read-only checks are in place.
The replication checks should be more flexible than in production (e.g. larger lag buffer) to avoid alert spam.
db1117 does have them
db1135 or db2062 do not have them
db2065 has them
