Monitored Metrics

Introduction

This topic describes metrics reported by dedicated WAF to Cloud Eye as well as their namespaces and dimensions. You can use APIs provided by Cloud Eye to query the metrics of the monitored object and alarms generated for dedicated WAF. You can also query them on the Cloud Eye console.

namespaces

SYS.WAF

Note

A namespace is an abstract collection of resources and objects. Multiple namespaces can be created in a single cluster with the data isolated from each other. This enables namespaces to share the same cluster services without affecting each other.
