Ask HN: What Are Your Approaches to API Monitoring and Infrastructure Monitoring?

Hello all,

I'm building a web-application using a micro services based architecture. And, I'm keen on learning the recommended approaches towards monitoring such systems (uptime, latency etc.)

So far I've been using tools like nagios/ ganglia/ bosun.org and pagerduty. and specifically ask, below are some of the questions I have,

- Which tools do you use for monitoring your infrastructure?

- Which other metrics must be monitored in addition to uptime and response-latency ?

- Do you use same tools for API Monitoring & Web Monitoring?

- How do you monitor api performance degradation?

- how do you track effect of a deployments on application performance?

- When is it wise to build internal or custom tool chains towards this?

Thanks!
