Pull From Your Historian

Senseye can connect directly to your historian to gather time series data. We support a range of historians out of the box and can develop custom integrations as required.

Your historian must be made accessible to Senseye. In terms of networking, we use a single egress IP address which can be whitelisted within firewalls. If required, we can support VPNs. We recommend that encryption is used during transit and a trusted certificate is applied to the historian. Furthermore, we require suitable authentication credentials and the correct level of access to the data within the historian.

When connecting to a historian, we do not copy the raw data. We will access the data in two situations:

1. The charts in the application show the raw data rather than aggregated data. In this situation, Senseye will request the raw data from your historian, as such, the historian's speed will have a direct impact on the performance of the Senseye web interface.
2. Calculating aggregations. Senseye will periodically check your historian for the presence of new data. When new data is found, hourly and daily aggregations will be calculated which are then stored within Senseye.
