It is OK to pass regular static `vmstorage` addresses together with `dns+srv` addresses at `-storageNode`. For example,
`-storageNode=vmstorage1,vmstorage2 -storageNode='dns+srv:vmstorage-autodiscovery'`.
The discovered addresses can be filtered with optional `-storageNode.filter` command-line flag, which can contain arbitrary regular expression filter.
For example, `-storageNode.filter='^[^:]+:8400$'` would leave discovered addresses ending with `8400` port only, e.g. the default port used
for sending data from `vminsert` to `vmstorage` node according to `-vminsertAddr` command-line flag.
The currently discovered `vmstorage` nodes can be [monitored](#monitoring) with `vm_rpc_vmstorage_is_reachable` and `vm_rpc_vmstorage_is_read_only` metrics.
