Nacos 0.8.0 version improves the monitoring system and supports access to third-party monitoring systems to monitor the running status of Nacos through exposed metrics data. Currently, prometheus, elastic search and influxdb are supported. The following is a combination of prometheus and grafana how to monitor Nacos, the official website grafana monitoring page . Combine with elastic search and influxdb to find relevant information by yourself
Nacos cluster exposes metrics data
Modify the configuration application.properties file in each node of the cluster to expose metrics data
cd /workspace/nacos/conf vim application.properties management.endpoints.web.exposure.include=* |
See if you can access metrics data
http://xx.xx.xx.xx:8848/nacos/actuator/prometheus
Deploy prometheus to collect Nacos metrics data
The download address is download prometheus
Unzip the prometheus compressed package and install
tar xvfz prometheus-*.tar.gz /workspace/ cd /workspace/prometheus |
Modify the configuration file, pay attention to the format indentation
vim prometheus.yml
- job_name: 'nacos-cluster' scrape_interval: 60s metrics_path: '/nacos/actuator/prometheus' static_configs: - targets: - 110.60.40.42:8848 - 110.90.5.47:8848 - 110.9.50.15:8848 |
Start prometheus service
cd /workspace/prometheus nohup ./prometheus --config.file="prometheus.yml" & |
Check the prometheus data through the browser, http://xx.xx.xx.xx:9090/graph
You can see the collected data of prometheus, search for nacos_monitor in the search bar, you can search for Nacos data, indicating that the collected data is successful
Deploy grafana to graphically display metrics data
Use yum to install grafana
sudo yum install https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.2.4-1.x86_64.rpm sudo service grafana-server start |
Login to grafana Default account password: admin
http://xx.xx.xx.xx:3000/?orgId=1
Configure prometheus data source
Import Nacos grafana monitoring template
Download link: https://github.com/nacos-group/nacos-template
Nacos monitoring is divided into three modules:
- Nacos monitor displays core monitoring items
- nacos detail shows the change curve of the indicator
- nacos alert is an alarm item
Nacos-Sync monitoring
With the release of Nacos 0.9 version, Nacos-Sync 0.3 version supports metrics monitoring, which can observe the running status of Nacos-Sync service through metrics data, which improves Nacos-Sync's monitoring capabilities in the production environment. Refer to Nacos Monitoring Manual for the construction of the overall monitoring system
grafana monitor Nacos-Sync
Like Nacos monitoring, Nacos-Sync also provides monitoring templates, import monitoring templates
Nacos-Sync monitoring is also divided into three modules:
- nacos-sync monitor displays core monitoring items
- nacos-sync detail and alert display monitoring curves and alarms
