Hello, I have a issue in  my url monitor is not polling.

Recently, I dont have alerts when I down my services (urls), before I have alert for this events 

In the monithos show that the last pool was:

  Next Poll at 13 Jan 2017 05:50:40 AM CST

Match Content

 Last Polled at 13 Jan 2017 05:46:41 AM CST

Last Alarm

I do this test, I have down the service and I check the monitor url and all look ok,  so  I click for update the status and the status has changed to down and the alert send to the mail only occurs when I do this.

Please your help

Regards
