Updated: 3-9-2017

You may need an additional polling engine for your environment. If you encounter the following issues or performance, you may need to add one or more additional pollers:

  • Polling completion rates are lower than expected which leads to gaps in data.
  • Sporadic component monitor timeouts usually resulting in component monitors showing an "Unknown" status, reporting the error, "Connection timeout. Job canceled by scheduler."
  • Resource exhaustion on the SQL server.

Installing additional pollers and Web Consoles help you extend your SolarWinds Server & Application Monitor (SAM) implementation. You can install additional polling engines to aid you in load balancing and configure additional websites to ensure redundant access through more than one web server. By sharing the same database, you can also share a unified user interface, making the addition of polling engines transparent to your staff.

These components are licensed and purchased separately from your main SolarWinds Server & Application Monitor install and require the installation of the SolarWinds SAM Additional Polling Engine. For more information about purchasing licenses, contact your sales representative ( or customer service.
