## Remarks

* This command is interactive unless you use either `--yes` or `--json` flag to override interactive behavior.
* The `memsqlctl remove-aggregator` command is equivalent to the [sdb-admin remove-aggregator](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-admin-commands/remove-aggregator.md) command.

## Output

The following is the standard output for the `remove-aggregator` command.

```shell
sudo memsqlctl remove-aggregator --host "172.17.0.3"

```

```output

memsqlctl will perform the following actions on the local master aggregator on port 3306:
  · Run `REMOVE AGGREGATOR 172.17.0.3:3306`

Would you like to continue? [y/N]: y
