Symptoms that may indicate you need an additional polling engine include, but are not limited to, the following:

  • 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 cancelled by scheduler."
  • Resource exhaustion on the SQL server.
