Essential Monitoring Metrics for Cloud Native Systems - Part 2

A practical guide

In the first part, I covered the two initial signals to diagnose that something is wrong:

• Latency
• Traffic

I mentioned two more signals:

• Errors
• Saturation

These two tell you something more important - whether the system is approaching failure. And this is where monitoring becomes truly operational. I will cover those two signals in this blog. Let us start with Errors.
