Hijacking this spot to highlight newrelic as a company I used to evangelize and now will go out of my way to recommend against (I consult startups as a virtual CTO). They used to have a brilliant offering (Application level monitoring with all associated hosts included) then they deprecated the host monitoring and jacked the price up on every one of my clients while simultaneously threatening them to collect based on the new plans. Every month was a new account rep reaching out to introduce themselves. My love affair ended when a message to the CMO resulted in them forcing the account into free tier without so much as a reply - basically what I'd expect from someone who designed such an org. Moved all the remaining clients off of it (5 digit MRR) to datadog and didn't look back. Later worked with a former engineer and he attested it was a shit show after they set their sights on an IPO. They had really really strong tech and product culture up until then.
Was kind of a death rattle for me and sure enough after they IPOd they really did nothing.
Still makes me angry when I think of it cause it was such a kick-ass product.
