Orion Fast Poll and Node Statuses Explained

Table of contents

Updated August 15, 2018

Overview

In Orion, nodes will sometimes enter a warning or down status. This article explains what actions are being performed in the background to determine node statuses.

Environment

  • Orion Platform. all versions
  • All Orion Platform products

Detail

Fast polling is a built-in feature that causes nodes to go into a warning state. By default, Orion will poll nodes every 2 minutes to track uptime. As soon as the node does NOT respond to a ping, two things change. The node will enter a warning status and the Orion server will begin pinging the node at 10 second intervals for 120 seconds. If the node responds during the 120 second fast polling period then it will be returned to a green/up status and resume the regular 2 minute interval pings. If the node does NOT respond during that time the node will be marked as down after 120 seconds (12 failed pings later). It will also resume the default 2 minute interval ping to check if the node has come back online. 

 

Fast polling is a built-in feature and cannot be disabled. You cannot change the duration of the fast ping either. You can, however, change the frequency of the fast poll. The setting is set here: 
Settings > All Settings > Polling Settings > under the 'Calculations & Thresholds' section > Node Warning Level (minimum is 10 seconds).
