Chegg uses a servlet filter to collect metrics on each request and forward them to Graphite and New Relic. We can configure that because we have hooks into the webapp config.
This works with 4.10.4. We haven’t tried it with a later version, but it could be a blocker for upgrading. Our SLA commitments to internal clients are based on 95th percentile response times. We need to track those. We could (should) contribute this, but it would still be an “edit the code” integration for different metrics systems. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Oct 7, 2016, at 4:13 PM, Renee Sun <renee_...@mcafee.com> wrote: > > I just read through the following link Shawn shared in his reply: > https://wiki.apache.org/solr/WhyNoWar > > While the following statement is true: > > " Supporting a single set of binary bits is FAR easier than worrying > about what kind of customized environment the user has chosen for their > deployment.
