I use Sentry with most of my clients, and for effective debugging I need to spin my own Sentry in a Docker container which ends up being quite heavy on my machine especially when combined with Grafana and Prometheus.
I'm really unhappy with virtually all monitoring/telemetry/tracking solutions.
It really feels they are all designed to vendor lock you in their expensive cloud solutions and I really don't feel I'm getting my $s back at all. Worst of all those cloud vendors would rather add new features non-stop rather than honing what they currently have.
Their sales are everywhere, I've seen two different clients getting Datadog sales people join private Slacks to evangelize their products.
Both times I escalated to the CTO, both times I ended up suspecting someone in management had something to gain from pushing teams to adopt those solutions.
