-WhatsUp Gold v14.x or v15.x
-WhatsUp Gold v16.1 SP1, SP2, SP3, or SP4

Configuring ELM Reports for WhatsUp Gold

WhatsUp Gold version 15.0 and later provides integration with the Event Log Management central database. For access to ELM reports and data, you must also have ELM products, (WhatsUp Event Archiver and/or WhatsUp Event Alarm), configured to send collected log data to a MS SQL Server. WhatsUp Gold accesses report data through stored procedures in the ELM database. For more information, see Using ELM Reports in WhatsUp Gold.


Potential SQL Server Express installation errors

Configuring the firewall to allow WMI traffic

WhatsUp Gold uses Windows Management Instrumentation (WMI) to monitor and restart Windows Services. For each device that is assigned an NT Service Active Monitor, you must supply the Windows credentials. Also, when creating a Service Restart Action, you must supply Windows credentials for each Action. Credentials must have administrative permissions on the remote server. Local accounts with credentials that match remote accounts are no longer required to monitor remote servers.

Credentials are configured in the WhatsUp Gold Credentials Library and used in several places throughout WhatsUp Gold. They can also be associated to devices in Device Properties > Credentials, or through Bulk Field Change for Credentials.

The use of WMI could have some implications if target devices are behind a firewall. To successfully monitor and/or restart NT Services, you need to modify firewall settings so that:

  1. The RPC port (135) is open for connections.
  2. The DCOM port range is defined and open for connections.

For more Troubleshooting information, see the Troubleshooting section in the application Help or User Guide.
