-General Settings
-================
-
-``ms tcp nodelay``
-
-:Description: Disables nagle's algorithm on messenger tcp sessions.
-:Type: Boolean
-:Required: No
-:Default: ``true``
-
-
-``ms initial backoff``
-
-:Description: The initial time to wait before reconnecting on a fault.
-:Type: Double
-:Required: No
-:Default: ``.2``
-
-
-``ms max backoff``
-
-:Description: The maximum time to wait before reconnecting on a fault.
-:Type: Double
-:Required: No
-:Default: ``15.0``
-
-
-``ms nocrc``
-
-:Description: Disables crc on network messages. May increase performance if cpu limited.
-:Type: Boolean
-:Required: No
-:Default: ``false``
-
-
-``ms die on bad msg``
-
-:Description: Debug option; do not configure.
-:Type: Boolean
-:Required: No
-:Default: ``false``
-
-
-``ms dispatch throttle bytes``
-
-:Description: Throttles total size of messages waiting to be dispatched.
-:Type: 64-bit Unsigned Integer
-:Required: No
-:Default: ``100 << 20``
-
-
-``ms bind ipv6``
-
-:Description: Enable if you want your daemons to bind to IPv6 address instead of IPv4 ones. (Not required if you specify a daemon or cluster IP.)
-:Type: Boolean
-:Required: No
-:Default: ``false``
-
-
-``ms rwthread stack bytes``
-
-:Description: Debug option for stack size; do not configure.
-:Type: 64-bit Unsigned Integer
-:Required: No
-:Default: ``1024 << 10``
-
-
-``ms tcp read timeout``
-
-:Description: Controls how long (in seconds) the messenger will wait before closing an idle connection.
-:Type: 64-bit Unsigned Integer
-:Required: No
-:Default: ``900``
-
-
-``ms inject socket failures``
-
-:Description: Debug option; do not configure.
-:Type: 64-bit Unsigned Integer
-:Required: No
-:Default: ``0``
-
-Async messenger options
-=======================
-
-
-``ms async transport type``
-
-:Description: Transport type used by Async Messenger. Can be ``posix``, ``dpdk``
- or ``rdma``. Posix uses standard TCP/IP networking and is default.
- Other transports may be experimental and support may be limited.
-:Type: String
-:Required: No
-:Default: ``posix``
-
-
-``ms async op threads``
-
-:Description: Initial number of worker threads used by each Async Messenger instance.
- Should be at least equal to highest number of replicas, but you can
- decrease it if you are low on CPU core count and/or you host a lot of
- OSDs on single server.
-:Type: 64-bit Unsigned Integer
-:Required: No
-:Default: ``3``
-
-
-``ms async max op threads``
-
-:Description: Maximum number of worker threads used by each Async Messenger instance.
- Set to lower values when your machine has limited CPU count, and increase
- when your CPUs are underutilized (i. e. one or more of CPUs are
- constantly on 100% load during I/O operations).
-:Type: 64-bit Unsigned Integer
-:Required: No
-:Default: ``5``
-
-
-``ms async set affinity``
-
-:Description: Set to true to bind Async Messenger workers to particular CPU cores.
-:Type: Boolean
-:Required: No
-:Default: ``true``
-
-
-``ms async affinity cores``
-
-:Description: When ``ms async set affinity`` is true, this string specifies how Async
- Messenger workers are bound to CPU cores. For example, "0,2" will bind
- workers #1 and #2 to CPU cores #0 and #2, respectively.
- NOTE: when manually setting affinity, make sure to not assign workers to
- processors that are virtual CPUs created as an effect of Hyperthreading
- or similar technology, because they are slower than regular CPU cores.
-:Type: String
-:Required: No
-:Default: ``(empty)``
-
-
-``ms async send inline``
-
-:Description: Send messages directly from the thread that generated them instead of
- queuing and sending from Async Messenger thread. This option is known
- to decrease performance on systems with a lot of CPU cores, so it's
- disabled by default.
-:Type: Boolean
-:Required: No
-:Default: ``false``
