<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: HTTP Push Data Sensor

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.

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?

Parent Tags

The tags that the sensor inherits from its parent device, parent group, and parent probe.

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:

• pushsensor
• pushdata
• httppushsensor

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

Define the security of the incoming HTTP push requests:

• HTTP (unsecure): Send push messages to the probe system via HTTP (not secure).
• HTTPS low security (TLS 1.0 to 1.3 and weak ciphers): Send push messages to the probe system via HTTPS. The sensor supports connections secured with TLS 1.0 to TLS 1.3 and weak ciphers. It uses the SSL certificate that is delivered with PRTG or your own trusted SSL certificate that you imported for the PRTG web server.
  If you install the sensor on a remote probe, make sure that you import the same SSL certificates to the remote probe that you use on the PRTG core server.

• HTTPS high security (TLS 1.2 to 1.3 and strong ciphers): Send push messages to the probe system via HTTPS. The sensor supports connections secured with TLS 1.2 to TLS 1.3 and strong ciphers. It uses the SSL certificate that is delivered with PRTG or your own trusted SSL certificate that you imported for the PRTG web server.
  If you install the sensor on a remote probe, make sure that you import the same SSL certificates to the remote probe that you use on the PRTG core server.

You cannot change this value after sensor creation.

Port

This setting is only visible if you enable HTTP (unsecure) above. Enter the number of the port on which this sensor listens for incoming HTTP requests. The default port is 5050.

You cannot change this value after sensor creation.

TLS Port

This setting is only visible if you enable HTTPS low security (TLS 1.0 to 1.3 and weak ciphers) or HTTPS high security (TLS 1.2 to 1.3 and strong ciphers) above. Enter the number of the port on which this sensor listens for incoming HTTPS requests. The default port is 5051.

You cannot change this value after sensor creation.

Request Method

Select the request method of the webhook:

• ANY: Do not use any filter for the request method.
• GET: Select this method if the webhook uses GET.
• POST: Select this method if the webhook sends POST data.
  POST data must be form-encoded request bodies with the same parameters as for GET requests.

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.

Request Handling

Define what PRTG does with the incoming messages:

• Discard request: Do not store the pushed messages.
• Store result: Store the last message received from the sensor in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Request for Sensor [ID].txt. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

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.

Value Type

Define the type of the value of the received data:

• Integer

• Float (with a dot . between the predecimal position and the decimal places)

If this setting does not match, the sensor shows the Down status.

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 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.

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

[Value]

The received value and an optional message in one channel

This channel is the primary channel by default.
