New customer installation

Return to top

DPAIM can be installed in either of the following ways:

  • With SolarWinds SAM

    DPAIM is automatically installed with SolarWinds SAM 6.2.1 or later. If you have SAM 6.2.1 or later, you do not need to install DPAIM. All you have to do is set up the integration module.

    To install SAM, use the SolarWinds Orion Installer.

  • Standalone (SAM not required)

    If you do not plan to install SAM, download and run the SolarWinds Orion Installer to install DPAIM as a separate product. You can install DPAIM alone, or you can install DPAIM with other Orion Platform products such as SolarWinds SRM.

After you install DPAIM, you must set up the DPA Integration Module.

How to upgrade

Use the SolarWinds Orion Installer to upgrade DPAIM and any other Orion Platform products.

If you are upgrading from the Orion Platform 2019.2 or later, you can upgrade your entire Orion deployment from the My Orion Deployment page. Downloading the Orion Installer is no longer necessary.


Fixed issues in DPAIM 2020.2.6

Return to top

DPAIM 2020.2.6 fixes the following issues.

Case Number Description
00593838, 00783029

The default value of the advanced configuration option FederationSchemaRefreshTimeout was increased from 30 seconds to 300 seconds. This change prevents DPA integration from failing on busy servers.

00740648, 00793481

The Secure Configuration for the Orion Platform guidelines recommend setting an Advanced Configuration option to specify that the Orion Platform should validate remote server certificates. When this option is set, the Orion Platform does not trust the default self-signed certificate on the DPA server, which prevents integration. If this occurs, DPAIM now displays a message to explain what is preventing integration.

To resolve this issue you can do either of the following:

  • (Recommended) Configure the DPA server to use a certificate that is trusted by the Orion Platform. The certificate must be issued by an authority that is included in the Orion server trust store. When you generate the certificate, make sure that it contains the host name that people use to access the DPA web console and also the host name that will be used for integration. Use the Subject Alternative Name field to include multiple host names.

  • Export the DPA self-signed certificate, and then import that certificate to the Orion server and any additional polling engines. When you set up DPA integration, use the host name that is included in the certificate.

Known issues

Return to top

Some DPA data is not displayed correctly in PerfStack
Issue: DPA data that represents a time series and can include multiple metrics is not displayed correctly in PerfStack charts. What should be shown as stacked graphs is displayed as a single line. 
Resolution/Work-around: None. 
Date range is one day behind on Wait Time resources

Issue: The date on Wait Time Trends resources is one day behind for environments where the DPA and Orion servers are in different time zones. The affected resources are:

  • All Instances with the Highest Wait Times
  • Instances with the Highest Wait Times
  • Greatest Downward Wait Time Trends
  • Greatest Upward Wait Time Trends
Resolution/Work-around:Set the DPA and Orion servers to the same time zone. 
DPAIM stops working after failover
Issue: If you have High Availability configured, the DPA Integration Module stops working when a failover occurs after you re-integrate with a previously integrated DPA server.
Resolution/Work-around: Re-integrate the DPA server.
