<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: HTTP IoT Push Data Advanced Sensor
The HTTP IoT Push Data Advanced sensor displays data from messages that are received from Internet of Things (IoT) capable devices (for example, Sigfox devices) and that are pushed via an HTTPS request to PRTG. It provides a URL that you can use to push messages to the probe system via HTTPS (secured with TLS 1.3 and weak ciphers).
This sensor is especially useful when you want to push data to a PRTG Hosted Monitor instance.
For more information about the sensor usage, see section How to Use.

Remarks
This sensor has a fixed port (5051). You cannot change it.
This sensor has a fixed SSL/TLS version (HTTPS (secured with TLS 1.3 and weak ciphers)). You cannot change it.
If you want to add this sensor to a remote probe and use an HTTPS connection to send push notifications, you must import a Secure Sockets Layer (SSL) certificate into the \cert subfolder of the PRTG program directory on the remote probe. However, this certificate does not have to match the certificate that you use on the PRTG core server. For more information about SSL certificates, see the Paessler website: How to use your own SSL certificate with the PRTG web server
This sensor does not support cluster probes. You can only set it up on local probes or remote probes.
This sensor supports IPv6.
This sensor has a low performance impact.
If you use this sensor with multiple channels, we recommend that you simultaneously push the data for all your channels to PRTG. You can push data to only one of your channels. However, all other channels record the value of 0 for this push message.
This sensor might result in false alerts if the parent probe disconnects from the PRTG core server. In this case, the sensor shows the error message: The latest push message that the sensor received is older than the specified time threshold allows. (code: PE222).
If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?
This setting is for your information only. You cannot change it.
Tags
Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.
It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).
For performance reasons, it can take some minutes until you can filter for new tags that you added.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
HttpPushSensor

Sigfox
Priority
Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority ().
TLS Settings

Description
TLS Port
The number of the port on which this sensor listens for incoming HTTPS requests. This is always 5051.
HTTP Push Authentication

Setting
Description
Identification Token
This is the token that PRTG uses to find the matching sensor for the incoming message. When you create the sensor, this token is {__guid__}.
PRTG replaces this token with an automatically generated token after sensor creation. If you want to use a different identification token, you can edit it during or after sensor creation.
PRTG does not automatically replace the token if you change it already during sensor creation.
HTTP Push Data
HTTP Push Data
Setting
Description
No Incoming Data
Define which status the sensor shows if it does not receive a push message for at least two scanning intervals:
Ignore and keep last status (default): Keep the status as defined by the last message that the sensor received. The parent probe must be connected to keep the last status. If the parent probe disconnects, the sensor shows the Unknown status. If the parent probe connects again, the sensor does not automatically switch from the Unknown status to the last status before the parent probe disconnected.
Switch to unknown status: Show the Unknown status if the sensor does not receive a message for at least two scanning intervals.
Switch to down status after x minutes: Show the Down status if the sensor does not receive a message within a specific time span. Define the time threshold below.
Time Threshold (Minutes)
This setting is only visible if you select Switch to down status after x minutes above.
Enter a time threshold in minutes. If this time elapses, the sensor shows the Down status if it does not receive a push message within this time span. Enter an integer. The maximum threshold is 1440 minutes.

Description
Primary Channel
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor.
You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.
Graph Type
Define how different channels are shown for this sensor:
Show channels independently (default): Show a graph for each channel.
Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic. You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).
Stack Unit
This setting is only visible if you select Stack channels on top of each other above.
Select a unit from the list. All channels with this unit are stacked on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.
Inherited Settings
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
Schedules, Dependencies, and Maintenance Window
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window (default).

How to Use
This function is known as a webhook. Basically, a webhook works like a push notification. Webhooks are usually triggered by an event (for example, a new comment on a blog post) and send according information to a specified URL. The HTTP IoT Push Data Advanced sensor then displays the data of pushed and received messages.
The data that is pushed to this sensor must be valid XML or JSON.
For more information about the return value format, see section Custom Sensors.
The HTTP IoT Push Data Advanced sensor uses the following URLs depending on the type of HTTPS request.
GET (default) requests: https://<probe_ip>:5051/<token>?content=<valid XML_or_JSON> The XML-encoded value of the content parameter has to match the format defined in section Custom Sensors.
POST requests: https://<probe_ip>:5051/<token> This HTTPS request method sends the XML-encoded or JSON-encoded HTTPS body as POST data. The body has to match the format defined in section Custom Sensors. We strongly recommend the HTTPS content type application/xml or application/json.
Replace the parameters <probe_ip>, <token>, and <valid XML_or_JSON> (for GET requests) with the corresponding values:
For PRTG Network Monitor, the probe IP is the IP address of the probe system.
For PRTG Hosted Monitor instances, the probe IP is the Domain Name System (DNS) name of the instance.
The port number is always 5051. You cannot change this.
You can define identification token in the sensor settings.
The content of GET requests has to be valid XML or JSON in the PRTG API format.
The content has to be URL encoded (for example, the whitespaces in the sample URL below). Most browsers do the URL-encoding automatically.
Minimum example for the GET method that returns one static channel value:
By default, values within the <value> tags in the returned XML or JSON must be integers for them to be processed. If float values are returned, you must explicitly define this value type as defined in section Custom Sensors with <float> tags, otherwise the sensor shows 0 values in affected channels. Example:
You can use several sensors with the same port and identification token. In this case, push message data is shown in each of these sensors.
Channel List
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
