监控 5.31.0 和 https/443 检查失败

Question

我在同一台服务器上有两个 WordPress 站点。两者都使用 LetsEncrypt。一个人不断失败，另一个人成功。我不知道为什么！

check host example-a.com with address www.example-a.com
if failed icmp type echo count 5 with timeout 150 seconds then alert
if failed port 443 protocol https with timeout 150 seconds then alert
if failed (url https://example-a.com/ and content == '' and timeout 40 seconds) then alert

check host example-b.com with address www.example-b.com
if failed icmp type echo count 5 with timeout 150 seconds then alert
if failed port 443 protocol https with timeout 150 seconds then alert
if failed (url https://example-b.com/ and content == '' and timeout 40 seconds) then alert

                                                                                     

检查

monit status

：

Remote Host 'example-a.com'
  status                       OK
  monitoring status            Monitored
  monitoring mode              active
  on reboot                    start

因为一项检查有效，所以我认为这不是监控问题。但除此之外还会是什么呢？

Answer 1

基于Monit 5.31.0和5.33.0，我看不出有什么问题，它运行良好。

Remote Host 'example-a.com'
  status                       OK
  monitoring status            Monitored
  monitoring mode              active
  on reboot                    start
  ping response time           -
  port response time           2.784 ms to example-a.com:8081/ type TCP/IP protocol HTTP
  port response time           0.342 ms to example-a.com:8081 type TCP/IP protocol HTTP

Remote Host 'example-b.com'
  status                       OK
  monitoring status            Monitored
  monitoring mode              active
  on reboot                    start
  ping response time           -
  port response time           0.751 ms to example-b.com:8989/ type TCP/IP protocol HTTP
  port response time           0.651 ms to example-b.com:8989 type TCP/IP protocol HTTP

但是你的配置看起来很奇怪，我在手册中找不到类似的东西。

if failed (url https://example-a.com/ and content == '' and timeout 40 seconds) then alert

我认为“content == ''”应该始终匹配。
