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 1.2).
This sensor is especially useful when you want to push data to a PRTG Hosted Monitor instance.

▪This sensor has a fixed port (5051). You cannot change it.
▪This sensor has a fixed SSL/TLS version (HTTPS secured with TLS 1.2 only). You cannot change it.
▪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 but, in this case, all other channels record the value of 0 for this push message.
▪If you want to install this sensor on a remote probe and use an HTTPS connection to send push notifications, you need to make sure that you import the same Secure Sockets Layer (SSL) certificates to the \cert subfolder of the PRTG program directory on the remote probe that you use on the PRTG core server. For more information, see the PRTG Manual: Using Your Own SSL Certificate with the PRTG Web Server
▪You cannot use this sensor in cluster mode. You can only set it up on a local probe or a remote probe but not on a cluster probe.
▪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).
▪This sensor supports the IPv6 protocol.
▪This sensor has a low performance impact.
▪For more information about the sensor usage, see the PRTG Manual: How to Use.
The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the settings that are required to create the sensor. You can change nearly all settings on the sensor's Settings tab after creation.
Click the Settings tab of a sensor to change its settings.
Basic Sensor Settings
Setting |
Description |
|---|---|
Sensor Name |
Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.
|
Parent Tags |
Shows tags that the sensor inherits from its parent device, parent group, and parent probe.
|
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.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor: ▪pushsensor ▪pushdata ▪httppushsensor ▪iot ▪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 ( |
Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.
TLS Settings
Setting |
Description |
|---|---|
TLS Version |
The security of the incoming HTTPS push requests: ▪HTTPS (secured with TLS 1.2 only): Send push messages to the probe system via HTTPS. The sensor only supports connections that are secured with TLS 1.2. It uses the SSL certificate that is delivered with PRTG or your own trusted SSL certificate that you imported for the PRTG web server.
|
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.
|
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. ▪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. |
Sensor Display
Setting |
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.
|
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. |
Stack Unit |
This setting is only visible if you enable Stack channels on top of each other as Graph Type. 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. |
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 Inheritance of Settings.
Scanning Interval
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.
Access Rights
For more information, see section Root Group Settings, section Access Rights.
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 details 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 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:
https://127.0.0.1:5051/XYZ123?content=<prtg><result><channel>MyChannel</channel><value>10</value></result><text>this%20is%20a%20message</text></prtg>
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:
https://127.0.0.1:5051/XYZ123?content=<prtg><result><channel>MyChannel</channel><value>10.45</value><float>1</float></result><text>this%20is%20a%20message</text></prtg>
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.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
Channel |
Description |
|---|---|
Downtime |
In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status |
