I have built a set of rocketmq clusters, and now I want to monitor the rocketmq clusters shown in the following table. The node_exporter and rocketmq_exporter have been introduced here, so today I will configure the corresponding exporter on Promethues.
| Machine node | ip | Remarks |
|---|---|---|
| promethues | 192.168.0.5 | promethues service node (rocketmq_exporter) |
| nameserver1 | 192.168.0.6 | nameserver node (node_exporter) |
| broker-a | 192.168.0.7 | broker node (node_exporter) |
| broker-a-s | 192.168.0.8 | broker node (node_exporter) |
Node_exporter needs to be installed on both nameserver and broker
Rocketmq_exporter can be installed on a fixed machine node (such as promethues node)
Node_exporter installation reference: Promethues: initial installation of rocketmq_exporter
rocketmq_exporter installation reference: Promethues: node_exporter initial installation
Configure promethues
Configuration file: promethues.yml
Location: /usr/local/prometheus/prometheus.yml
If you cannot find the location, you can use the following methods:
ps to | grep prometheus
The --config.file in the figure is the location of the configuration file
Configure node_exporter
Execution: vim /usr/local/prometheus/prometheus.yml
Add the following bold content in the scrape_configs field .
scrape_configs: #nameserver machine node monitoring-job_name: nameserver
Configure rocketmq_exporter
Execution: vim /usr/local/prometheus/prometheus.yml
Add the following bold content in the scrape_configs field .
scrape_configs:
Load configuration
1) Restart prometheus
service prometheus restart
2) Confirm whether rocketmq_exporter is OK
curl http://localhost:5557/metrics
3) Confirm whether node_exporter is OK
curl http://192.168.0.6:9100/metrics curl http://192.168.0.7:9100/metrics curl http://192.168.0.8:9100/metrics
4) Check the promethues log for errors
systemctl status prometheus -l
At this point, the node-exporter and rocketmq-exporterr of promethues have been configured, and the grafana panel will be configured later.
