Nacos performance metrics, including Nacos online length, Nacos Config long links, Nacos Config configuration number, Service Count, HTTP requests, and so on.

Configuration¶

Version support¶

Operating system support: Linux / Windows
Nacos version: >= 0.8.0

Description: Example Nacos version 1.4.1.

(same Linux / Windows environment)

Metric Collection (Required)¶

Configure application.properties files to expose metrics data

management.endpoints.web.exposure.include=*

Restart Nacos

There are differences between cluster mode and singleton mode start parameters, refer to Nacos 官方文档.

Verification

Visit {ip}:8848/nacos/actuator/prometheus to see if metrics data is accessible

Open the DataKit Prometheus plug-in

cd /usr/local/datakit/conf.d/prom/
cp prom.conf.sample nacos-prom.conf

Modify nacos-prom.conf Profile

Description of main parameters

Urls: prometheus Metric address, fill in the metric URL exposed by Nacos here
Source: alias of collector, recommended as nacos
Interval: collection interval
Measurement_ Prefix: index prefix for easy index classification query
Tls_ Open:TLS Configuration
Metric_ Types: Metric type, not filled in, representing the collection of all metrics
