Otis Gospodnetic commented on SOLR-9880:
----------------------------------------
May I recommend a different approach? With the current approach you'll always
have somebody come in and ask for additional reporter and typically that won't
be very high on Solr devs' interest, plus it will require more work, additional
dependencies, etc. Moreover, if you do this then you have to think about
things like destination not being available, about possible on-disk buffering
so data is not lost, about ensuring the buffered data is purged if there is too
much of it, and so on. Solr doesn't want to be in data shipper business. My
suggestion, based on working with monitoring and logging for the last N years -
just log metrics to a file. There are a number of modern tools that know how
to tail files, parse their content, ship it somewhere, have buffering, have
multiple outputs, and so on. Just make sure data is nicely structured to make
parsing easy, and done in a way that when you add more metrics you can do it in
a backwards-compatible way.

> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)

> Originally SOLR-4735 provided implementations for these reporters (wrappers
> for Dropwizard components to use {{SolrMetricReporter}} API).
> However, this functionality has been split into its own issue due to the
> additional transitive dependencies that these reporters bring:
> * Ganglia:
> ** metrics-ganglia, ASL, 3kB
> ** gmetric4j (Ganglia RPC implementation), BSD, 29kB
> * Graphite
> ** metrics-graphite, ASL, 10kB
> ** amqp-client (RabbitMQ Java client, marked optional in pom?), ASL/MIT/GPL2,
> 190kB
> IMHO these are not very large dependencies, and given the useful
> functionality they provide it's worth adding them.
