1. Background and Context Overview

Article related to the environment, prometheusmonitoring and grafanabasic environment is deployed. etcdBuilt-in metricsinterfaces for data collection, in etcdthrough the cluster node Renyiyitai ip:2379/metricswhether the data is normal to collect inspection.

curl -L http://localhost:2379/metrics

2, the configuration modification prometheus

Modified prometheusconfiguration, increased etcdmonitoring configuration, cluster configuration specified etcd ip:port, and specify the protocol type and a rear end arranged to skip verification CA

vim prometheus-configmap.yaml
- job_name: "etcd"
      scheme: https
      tls_config:
        insecure_skip_verify: true
      static_configs:
      - targets: ['172.16.1.100:2379','172.16.1.101:2379','172.16.1.110:2379']
