Troubleshooting Issues with Collectors

This topic contains solutions/workarounds to some of the common issues encountered with Configuration Hub. This list is not comprehensive. If the issue you are facing is not listed on this page, refer to Troubleshooting the Historian Server.
Proxy Timeout Error While Adding a Collector Instance
Description
When you attempt to add a collector, sometimes, a proxy error appears even if the error occurs because of an API timeout.
Workaround
  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.
Receiving a Collector Configuration Error
Description
A single ihConfigurationGetProperties[-2] error appears in the collector.LOG file.
Workaround
The error most likely occurred as a result of the collector connecting and querying for changes in the tag database immediately, getting a timeout, and then immediately querying again and succeeding.
