Environment Variables Used by the Server-to-Server Collector
Important: For OPCUA DA, Server-to-Server, and Server-to-Cloud collectors, ensure that you have set the environment variables correctly before applying the configuration changes. This is because after you have applied the configuration changes for a collector, you cannot set the environment variables. If, however, you must change the values of the environment variables after the applying the changes, you must change the InterfaceName and DefaultTagPrefix values. When you do so, a new instance of the collector is created. As a result, you must add the tags again.
| Environment Variable | Description | Default Value | Valid Values |
|---|---|---|---|
| HistorianNodeName | The host name of the Historian server to which you want to send data using the server-to-server collector. A value is required. You can choose to send data to an server that is on-premises or on Predix cloud. | ||
| InterfaceName | The name of the server-to-server collector. | historian-s2c | |
| DefaultTagPrefix | The default prefix for the tags created by the server-to-server collector. For example, if you enter s2s, for a tag named pressure, a tag with the following name is created: s2s.pressure | historian-s2c. | |
| General3 | The IP address of the Historian archiver. | ||
| OfflineTagConfigurationFile | The absolute path to the offline tag configuration file. | /config/tag-list.xml | |
| HS_NUMBER_OF_LOG_FILES | Maximum number of Log Files. Once this value exceeds, the oldest file will be deleted to accommodate new one. Its default value is 100, and range is from 1 to 100. | 100 | 1 to 100 |
| HS_SIZE_OF_EACH_LOG_FILE | Maximum size of one Log file in Mega Bytes. If this value exceeds, new Log File will be created. | 10 | 1 to 10 |
