This receiver can fetch stats from a Memcached instance using the stats command. A detailed description of all the stats available is at https://github.com/memcached/memcached/blob/master/doc/protocol.txt#L1159.

Details

Configuration

ℹ️ This receiver is in beta and configuration fields are subject to change.

The following settings are required:

• endpoint (default: localhost:11211): The hostname/IP address and port or, unix socket file path of the memcached instance
• transport (default: no default): Known protocols are "tcp", "tcp4" (IPv4-only), "tcp6" (IPv6-only), "udp", "udp4" (IPv4-only), "udp6" (IPv6-only), "ip", "ip4" (IPv4-only), "ip6" (IPv6-only), "unix", "unixgram" and "unixpacket".

The following settings are optional:

• collection_interval (default = 10s): This receiver runs on an interval. Each time it runs, it queries memcached, creates metrics, and sends them to the next consumer. The collection_interval configuration option tells this receiver the duration between runs. This value must be a string readable by Golang's ParseDuration function (example: 1h30m). Valid time units are ns, us (or µs), ms, s, m, h.
• initial_delay (default = 1s): defines how long this receiver waits before starting.

Example:

receivers:
  memcached:
    endpoint: "localhost:11211"
    collection_interval: 10s
    transport: tcp

The full list of settings exposed for this receiver are documented in config.go with detailed sample configurations in testdata/config.yaml.
