We use AppOptics. I am curious what are the current leaders for APM for small companies (50 employees) that use Python, MariaDB, RabbitMQ, and Google Cloud Storage. We run both Celery and Gunicorn services. We are considering Datadog or some other deep code profiling tool that can spot I/O, DB, or other response time/request rate issues
We are running Python & Celery, our stack is based on AWS ECS. We are using NewRelic. This tool is just amazing, both for API and Offline workers. It would provide any metric I was looking for, including a profiler, SLA / SLO dashboards, infrastructure metrics. It has alerting capability that is easily integrated with Pingdom / PagerDuty / Webhooks.
