Overview

Asserts growing library of assertions for cloud services and application frameworks.
Asserts curated a library of rules that constantly run on the incoming time-series data and surface key insights as assertions. To focus on what they imply for the system, we categorize these assertions into a SAAFE model: Saturation, Amend, Anomaly, Failure, and Error. Implementation-wise, Asserts have broadly two sets of rules that raise assertions: base rules and framework-specific rules.
Our base rules are for common request and resource metrics across platforms and frameworks. The table below summarizes all these base assertions raised by our base rules.

Our framework-specific rules raise many specific assertions, which usually belong to Failure, Amend, and Saturation categories. You can read more in Understanding SAAFE Model. Here is a sample set of frameworks and libraries we have built-in assertions for
