測試目標：客戶端node_explore停止，抑制了blackbox探測郵件告警功能。
客戶端安裝blackbox_exporter服務
[root@promethus blackbox_exporter]# ll
-rwxr-xr-x 1 3434 3434 14925964 3月 15 21:32 blackbox_exporter
-rw-r--r-- 1 3434 3434 629 3月 15 21:42 blackbox.yml
配置好blackbox.yml文件
[root@promethus blackbox_exporter]# vim blackbox.yml

配置文件

"hongk:9100"
],
"labels": {

測試方式，正常情況下運行，先使得blackbox掛掉，然后node_explore掛掉。測試結果：當blackbox掛掉，正常顯示blackbox相關url異常，當node_explore掛掉后，郵件只顯示node_explore掛掉。達到了預期效果。
告警部分配置。
