## Syntax {#syntax}

The [`mc support top rpc`](#command-mc.support.top.rpc) command displays metrics for remote procedure calls (RPC).

**EXAMPLE**

The following command displays the current remote procedure call metrics for the [alias](/glossary/#term-alias) `myminio` deployment.

```shell
mc support top rpc myminio/
```

The output returns information such as the server, number of connections, length of ping, time since last ping (`pong`), reconnections, string in, string out, messages in, and messages out.

The output resembles

```bash
λ mc support top rpc myminio
      SERVER            CONCTD  PING     PONG   OUT.Q   RECONNS STR.IN  STR.OUT MSG.IN  MSG.OUT

**SYNTAX**

The command has the following syntax:

```shell
mc [GLOBALFLAGS] support top rpc                 \
                             [--airgap]          \
                             [--in value]        \
                             [--interval value]  \
                             [-n value]          \
                             [--nodes value]     \
                             TARGET
```
