28.6. 创建和修改集群警报

流程

1. 创建简单警报。由于没有指定报警 ID 值，系统会创建 alert 的报警 ID 值。

   # pcs alert create path=/my/path

   Copy to Clipboard Toggle word wrap

2. 向警报添加一个接收者 rec_value 。由于这个命令没有指定接收者 ID，因此 alert-recipient 的值被用作接收者 ID。

   # pcs alert recipient add alert value=rec_value

   Copy to Clipboard Toggle word wrap

3. 向警报添加第二个接收者 rec_value2 。此命令为接收者指定 my-recipient 的接收者 ID。

   # pcs alert recipient add alert value=rec_value2 id=my-recipient

   Copy to Clipboard Toggle word wrap

4. 显示警报配置。

   # pcs alert config
   Alerts:
    Alert: alert (path=/my/path)
     Recipients:
      Recipient: alert-recipient (value=rec_value)
      Recipient: my-recipient (value=rec_value2)

   Copy to Clipboard Toggle word wrap

5. 添加第二个警报，警报 ID 为 my-alert。

   # pcs alert create id=my-alert path=/path/to/script description=alert_description options option1=value1 opt=val meta timeout=50s timestamp-format="%H%B%S"

   Copy to Clipboard Toggle word wrap

6. 为第二个报警添加一个接收者值为 my-other-recipient 的接收者。因为没有指定接收者 ID，系统会提供接收者 ID my-alert-recipient。

   # pcs alert recipient add my-alert value=my-other-recipient

   Copy to Clipboard Toggle word wrap

7. 显示警报配置。

   # pcs alert
   Alerts:
    Alert: alert (path=/my/path)
     Recipients:
      Recipient: alert-recipient (value=rec_value)
      Recipient: my-recipient (value=rec_value2)
    Alert: my-alert (path=/path/to/script)
     Description: alert_description
     Options: opt=val option1=value1
     Meta options: timestamp-format=%H%B%S timeout=50s
     Recipients:
      Recipient: my-alert-recipient (value=my-other-recipient)

   Copy to Clipboard Toggle word wrap

8. 修改警报 my-alert 的警报值。

   # pcs alert update my-alert options option1=newvalue1 meta timestamp-format="%H%M%S"

   Copy to Clipboard Toggle word wrap

9. 修改接收者 my-alert-recipient 的警报值。

   # pcs alert recipient update my-alert-recipient options option1=new meta timeout=60s

   Copy to Clipboard Toggle word wrap

10. 显示警报配置。

    # pcs alert
    Alerts:
     Alert: alert (path=/my/path)
      Recipients:
       Recipient: alert-recipient (value=rec_value)
       Recipient: my-recipient (value=rec_value2)
     Alert: my-alert (path=/path/to/script)
      Description: alert_description
      Options: opt=val option1=newvalue1
      Meta options: timestamp-format=%H%M%S timeout=50s
      Recipients:
       Recipient: my-alert-recipient (value=my-other-recipient)
        Options: option1=new
        Meta options: timeout=60s

    Copy to Clipboard Toggle word wrap

11. 从 alert 中删除接收者 my-alert-recipient。

    # pcs alert recipient remove my-recipient

    Copy to Clipboard Toggle word wrap

12. 显示警报配置。

    # pcs alert
    Alerts:
     Alert: alert (path=/my/path)
      Recipients:
       Recipient: alert-recipient (value=rec_value)
     Alert: my-alert (path=/path/to/script)
      Description: alert_description
      Options: opt=val option1=newvalue1
      Meta options: timestamp-format="%M%B%S" timeout=50s
      Recipients:
       Recipient: my-alert-recipient (value=my-other-recipient)
        Options: option1=new
        Meta options: timeout=60s

    Copy to Clipboard Toggle word wrap

13. 从配置中删除警报 myalert。

    # pcs alert remove myalert

    Copy to Clipboard Toggle word wrap

14. 显示警报配置。

    # pcs alert
    Alerts:
     Alert: alert (path=/my/path)
      Recipients:
       Recipient: alert-recipient (value=rec_value)

    Copy to Clipboard Toggle word wrap
