Monitoring Metrics

Function Description

This section describes monitoring metrics reported by WAF to Cloud Eye as well as their namespaces and dimensions. You can use the management console or APIs provided by Cloud Eye to query the monitoring metrics of the monitored object and alarms generated for WAF.

Namespace

SYS.WAF

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

Cloud WAF Monitoring Metrics

**Table 1** Monitoring metrics
Metric ID	Metric Name	Meaning	Value Range	Measurement Object & Dimension	Monitoring Interval (Raw Data)
attacks	attacks	Total number of attacks on a protected domain name in a given period	>= 0 count	Measurement object: protected domain name Dimension: waf_instance_id	5 minutes
requests	requests	Total number of requests for a protected domain name in a given period	>= 0 count	Measurement object: protected domain name Dimension: waf_instance_id	5 minutes
