istio prometheus預警Prometheus AlertManager 安裝 --誤區

 誤區：由於prometheus是一個pod不能重啓，因此此方案適用於單獨非容器安裝的prometheus。

1.進入pod

kubectl exec -n istio-system -it grafana-694477c588-8rbvc /bin/bash

2.下載安裝Prometheus AlertManager

grafana-cli plugins install camptocamp-prometheus-alertmanager-datasource

3.restart grafana service

service grafana-server restart

4.查看錯誤緣由

grafana-server -homepath /usr/share/grafana

 

Right. Something is already using port 3000.

Stop the grafana services
systemctl stop grafana.service -l

do a ps aux |grep grafana and kill if any process exits

Then start grafana using
systemctl stop grafana.service -l

Tailf for grafana logs

tailf /var/log/grafana/grafana.log

5.查看本地安裝的Plugin

grafana-cli plugins ls

service grafana-server restart
