Polling engines

SolarWinds Platform products support the implementation of multiple distributed polling engines. Each engine can monitor and collect data from different parts of your network.

Does your SolarWinds Platform product support additional polling engines? See Scalability Engine guidelines.

This page shows the status and selected configuration information for each currently operational polling engine.

  • Last Database Update is the most recent LastSync value from Nodes table. If this value and large and negative, the LastSync entry in the Nodes table is NULL. This may happen after a node is added but before it is first polled. LastSync is updated when node data is synchronized.
  • Last Database Sync is calculated as (UTC time on DB server - KeepAlive::InUTC), where KeepAlive is in the Engines table. KeepAlive is updated periodically.
