Promriak

Riak metrics re-exporter in the Prometheus text exposition format.

Note that while it is often verboten, promriak caches the retrieved metrics from each Riak instance inbetween scrapes and serves the cached values up until a stale threshold is reached.

Configuration

Configuration is searched for in the following locations:

./promriak.yaml 
/usr/local/etc/promriak/promriak.yaml
/etc/promriak/promriak.yaml

Alternatively, a configuration file path can be provided with the --config command line option or the PROMRIAK_CONFIG environment variable, where the former takes precedence:

promriak --config /path/to/my_promriak_config.yaml
PROMRIAK_CONFIG=/path/to/my_promriak_config.yaml promriak
