Check Memcached cluster status

To check the status of your Memcached Multiple instances:

  • Log in to the main server host through SSH.

  • Try to connect to the rest of Memcached instances using telnet (The placeholder MEMCACHED_INSTANCE_ADDRESS should be replaced with an actual address. Check this section to know how to retrieve the IP address of your instances).


NOTE: telnet is not installed by default. Learn how to install the telnet command line client.

If your Memcached instance is running you will see an output similar to this:

Connected to
Escape character is '^]'.

In order to exit the console type quit and press enter.

If on the contrary is not running you will get this error:

telnet: Unable to connect to remote host: Connection refused

In case of the previous error please check the following:

  • Check that the service is running. You can learn how in this section
  • Verify that the IP address used is the proper one.
  • Verify that the port number is correct. By default it is 11211.
