A memcached exporter for prometheus.
The memcached exporter exports metrics from a memcached server for
consumption by prometheus. The server is specified as --memcached.address flag
to the program (default is localhost:11211).
By default the memcache_exporter serves on port 0.0.0.0:9150 at /metrics
mcached_exporter
Alternatively a Dockerfile is supplied
er run -p 9150:9150 quay.io/prometheus/memcached-exporter:v0.4.1
The exporter collects a number of statistics from the server:
LP memcached_commands_total Total number of all requests broken down by command (get, set, etc.) and status.
PE memcached_commands_total counter
