配置prometheus的job
global:
scrape_interval:
15s
evaluation_interval: 15s
scrape_configs:
- job_name: 'prometheus'
static_configs:
- targets: ['localhost:9090']
- job_name: 'node_exporter'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9100']
- job_name: 'netcoreprometheus'
scrape_interval: 5s
scheme: https
tls_config:
insecure_skip_verify: true
metrics_path: /metrics-text
static_configs:
- targets: ['{demo_ip}:{demoport}']
为什么是metrics-text 参见appmetrics官方解释
/metrics-text will return metrics in Prometheus plain text format and /> metrics in Prometheus protobuf format.
重启prometheus
sudo systemctl restart prometheus
sudo systemctl status prometheus

配置Grafana仪表盘
直接可以用的仪表盘地址：
按之前配置的方式配置完成后，就可以看到grafana正常的从prometheus收集数据并展示了
