Prometheus手动打标签
目录
有时候需要给Prometheus打标签，比如说联邦集群接入，需要知道是哪个集群，remote write写入的时候也需要做个标记。
直接在集群打标签
vim prometheus.yml
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
external_labels:
env: uat
dept: ops
project: xxx
...
这样就可以给集群内的所有metrics打上这三个标签。
通过联邦集群打标签
如果集群不好进行操作，可以通过联邦集群接入，在联邦主节点进行配置
global:
scrape_interval: 15s
evaluation_interval: 15s
scrape_timeout: 10s
scrape_configs:
- job_name: 'federate-https'
scrape_interval: 15s
scrape_timeout: 15s
honor_labels: true
metrics_path: '/federate'
scheme: https
params:
'match[]':
- '{job=~".+"}'
static_configs:
- targets:
- '192.168.77.11:9090'
- '192.168.77.12:9090'
labels:
env: uat
dept: ops
project: xxx
给接入的target打标签
这种只是给当前这个target打标签，不是全局生效
- job_name: node_exporter
honor_timestamps: true
scrape_interval: 5s
scrape_timeout: 5s
metrics_path: /metrics
scheme: http
follow_redirects: true
static_configs:
- targets:
- 192.168.13.117:9100
- 192.168.13.118:9100
- 192.168.13.119:9100
labels:
env: uat
dept: ops
project: xxx
