If you need to generate a sensor data report, we recommend using the self-service backfill feature before generating the report. It checks for missing data and, if any gaps are found, lets you retrieve the missing data yourself without contacting support.
To use the new self-service backfill feature, your username must be an email address.
If this feature isn't available to you, ask a Customer Administrator to update your username to your email address. For instructions, see Modify a User.
CAM+ automatically restores missing data after interruptions in communication. However, this process can take up to 48 hours to complete. The self-service backfill feature allows you to prioritise the retrieval of data for a specific sensor and date range when the data is needed urgently. It will retrieve the data within approximately 15–30 minutes.
How to Check for Missing Data & Run a Backfill
You must have General Access permission for the department containing the sensor. This is the same permission required to view sensor data.
-
Log in to the CAM+ Website.
-
Click the sensor icon on the relevant department.
-
Click Backfill Data in the side menu (top left).
-
Check the box on the sensor that you want to backfill.
You can select multiple sensors.
-
Choose the date and time range that you want to retrieve data for.
-
You can request data up to the current date and time.
-
Each backfill request can cover a maximum period of 6 weeks.
-
You can request data from up to 3 years ago. However, if the WARP was installed less than 3 years ago, you can only request data from the date the WARP was installed onwards.
-
Click Analyse for Gaps.
-
Review the results:
-
If missing data is detected, you will see a message displayed in red, and the graph will show blank sections where data is unavailable.
-
If no gaps are found, no backfill is required.
-
If you selected multiple sensors, use the tabs above the graph to switch between sensors and review each one individually.
-
-
Click Submit Backfill Request. You will see an estimated completion time of approximately 15–30 minutes.
-
Click Requests to view backfill requests. You will see one of the following statuses:
|
Status |
Description |
|---|---|
|
Pending |
Your backfill request has been received and is waiting to be processed. |
|
Processing |
CAM+ is preparing the backfill request. |
|
Accepted |
The backfill request has been accepted, and the missing data is being retrieved. |
|
Completed |
The backfill has completed successfully, and the requested data has been retrieved. |
|
Incomplete Data |
The backfill completed, but some of the requested data could not be retrieved from the WARP. See Backfill Troubleshooting. |
|
Failed Missing Logs |
The backfill could not retrieve any of the requested data because the required data is not available on the WARP. See Backfill Troubleshooting. |
|
Failed |
The backfill request could not be completed because CAM+ could not communicate with the WARP. See Backfill Troubleshooting. |
-
You will receive an email notification when the request has been completed, and it will be marked as completed on the Requests page.
Note: If the WARP is currently offline, the backfill request cannot be processed. Resolve the connectivity issue first (see WARP Troubleshooting), then submit the request again.
-
After approximately 30 minutes, you can generate a sensor data report.
Automatic backfill still occurs
CAM+ automatically restores missing data after interruptions in communication. The self-service backfill feature does not replace this process. Instead, it prioritises a specific sensor and date range when the data is needed urgently.
Historical data availability
Backfill requests retrieve data directly from the WARP.
You can request a backfill for data from up to 3 years ago. However, this period may be shorter if the WARP was installed less than 3 years ago.
For example, if a WARP was installed in 2024, backfill requests can only retrieve data from 2024 onwards.
If a WARP has been replaced, any missing data from the previous WARP is automatically backfilled during the replacement process. Therefore, there will not be any missing data from before the new WARP was installed.
