Yours truly, writing a guest post on Datadog’s blog about the Couchbase integration we created awhile back:
… Datadog has become our exclusive performance monitoring and graphing tool because it strikes the right balance between ease of use, flexibility, and extensibility and provides our team with tremendous leverage.
We love the fact that the Datadog team decided to make their agent an open-source project. This makes it super simple to create your own custom checks and contribute them back to the community. We did just that six months ago when we wrote a new custom check for Couchbase.
