Configuration

Edit the python.d/memcached.conf configuration file using edit-config from the your agent’s config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/memcached.conf

Sample:

localtcpip:
  name     : 'local'
  host     : '127.0.0.1'
  port     : 24242

If no configuration is given, module will attempt to connect to memcached instance on 127.0.0.1:11211 address.
