Node polling failed on last 5 tries

Product section

Orion Platform

Cause

This occurs when the SQL Server where the database is hosted and Orion server do not have "the same time" which means while converting local (servers') time to the UTC they are different.

For example:

  • Correct setup
    • SQL Server - 11:48 AM UTC+3 = 8:48 AM UTC
    • Orion server - 11:48 AM UTC+3 = 8:48 AM UTC
       
  • Incorrect setup 1
    • SQL Server - 4:48 AM UTC+2 = 2:48 AM UTC
    • Orion server - 4:48 AM UTC+3 = 1:48 AM UTC

 

  • Incorrect setup 2
    • SQL Server - 3:48 AM UTC+2 = 1:48 AM UTC
    • Orion server - 4:48 AM UTC+3 = 1:48 AM UTC

Resolution

Make sure that all Orion Servers (Polling Engines, Web Servers, HA Standby Servers, SQL Server, etc.) are on the Same Time Zone.

You can also use a time reference, for example, the NTP server, to synchronize time on servers to the universal source. See How to Synchronize Microsoft Windows to a NTP server.  (content provided by TimeTools, available at http://timetoolsltd.com obtained on January 23, 2018).
