Hi dev@, *What?* I've been chipping away at some documentation which would provide a one-stop-shop for understanding Nutch metrics. My first pass is available at https://cwiki.apache.org/confluence/display/NUTCH/Metrics This relates to the recent JIRA issue I filed about establishing a Nutch metrics convention. https://issues.apache.org/jira/browse/NUTCH-2909
*My ask* It is probably unrealistic for me to ask for a review of the metrics documentation due to the document length. I suppose it can be used more as reference material further down the line. Therefore my request is simple, if you are able to take a look at NUTCH-2909 it would be greatly appreciated. *My intention* Depending on what feedback I get, I intend to 1. begin with applying the naming convention across all existing Hadoop counters updating the above documentation as I go 2. prototype and experiment with sending Nutch metrics to systems like StatsD (https://github.com/apache/nutch/pull/712) and Prometheus. 3. based on #2, roll out a fully blown metrics implementation which would allow expressive metrics to be collected in a dedicated metrics system. The overall goal is to assist Nutch administrators by better informing them about how Nutch runs in production. This is a pretty large task so it will most likely take a couple more months. lewismc -- http://home.apache.org/~lewismc/ http://people.apache.org/keys/committer/lewismc
