It's been a breath of fresh air this summer to pull out New Relics agent libraries from several of our apps and have them replaced with OpenTelemetry dittos with auto-instrumentation turned off.

No more outages because NR's .NET agent generates code at runtime that causes segfaults. No more outages from the JS agent leaking memory if you instrument long-running functions. No more junior python devs spending days chasing the wrong call path because the Python agent produces bogus timing data on async python..

Just a dumb thing where we can ask for important flows to be traced and set up simple metrics for the things we want to keep track of.

Now we can keep using NRs dashboards, NRQL etc backend systems, which IMO are really good, without the downside of monthly outages each time we update an NR agent library.
