Memcached

Auto-Detection

Built-in Metrics

Memcached is a high-performance, distributed in-memory caching system.

Auto-Detection

Glouton detects Memcached by its process and listening port (default: 11211).

If auto-detected parameters are incorrect, override them manually:

Linux
Windows

sudo tee /etc/glouton/conf.d/99-memcached.conf > /dev/null << 'EOF'
service:
  # For a Memcached running outside a container
  - type: "memcached"
    address: "127.0.0.1"
    port: 11211

  # For an additional Memcached running outside a container
  - type: "memcached"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 11212

  # For a Memcached running in a Docker container
  - type: "memcached"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 11211
EOF

Create or edit C:\ProgramData\glouton\conf.d\99-memcached.conf:

service:
  # For a Memcached running outside a container
  - type: "memcached"
    address: "127.0.0.1"
    port: 11211

  # For an additional Memcached running outside a container
  - type: "memcached"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 11212

  # For a Memcached running in a Docker container
  - type: "memcached"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 11211

Glouton automatically detects configuration changes.

Health Check

Glouton performs a Memcached protocol check on the configured port to verify that the server is responding.
