Troubleshooting Collectors

Proxy Timeout Error While Adding a Collector Instance

When you attempt to add a collector, sometimes, a proxy error appears even if the error occurs because of an API timeout. To view the actual cause of the error:
  1. Access the historian-httpd.conf file located at C:\Program Files\GE\Operations Hub\httpd\conf\app-specific.d.
  2. Increase the timeout value (for example, 250). If the timeout parameter is not available, enter it as follows: ProxyTimeout <value>
  3. Restart the GE Historian Tomcat Server and the GE Operations Hub Httpd Reverse Proxy services.

Troubleshooting the OPC UA Data Access (DA) Collector

The OPC UA Data Access (DA) collector gathers and collects data from any OPC UA 1.0-compliant OPC UA DA server. The OPC UA DA collector automatically determines the capability of the OPC UA DA server to which it is connected, and supports the appropriate features based on this information.

Troubleshooting the OPC Classic HDA collector

The OPC Classic HDA collector collects data from any OPC HDA 1.2 -compliant OPC Classic HDA server. The OPC Classic HDA server automatically determines the capability of the OPC HDA Server to which it is connected, and supports the appropriate features based on this information.
Note: GE assumes no responsibility for the ability for the OPC Classic HDA collector to connect to specific HDA servers.
