Performance impact

This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.

.NET 4.7.2 or later

This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node.

If the framework is missing, you cannot create this sensor.

For more information, see the Knowledge Base: Which .NET version does PRTG require?

IPv6

This sensor supports IPv6.

Calling Application Entity Title

Enter the Application Entity Title (AET) of PRTG to initialize a DICOM connection.

The AET is case-sensitive and does not support special characters.

Called Application Entity Title

Enter the AET of the target system to initialize a DICOM connection.

The AET is case-sensitive and does not support special characters.

Port

Enter the port of the DICOM interface to use for the connection. The default port is 104.

Timeout (Sec.)

Enter a timeout in seconds for the request. Enter an integer. The maximum timeout value is 900 seconds (15 minutes).

If the reply takes longer than this value, the sensor cancels the request and shows a corresponding error message.

C-FIND Level

Define the search level of the C-FIND request:

• Patient: Retrieve data from the patient column via C-FIND. Enter a search key below.
• Study: Retrieve data from the study column via C-FIND. Enter a search key and a modality below.
• Series: Retrieve data from the series column via C-FIND. Enter a search key and a modality below.
• Worklist: Use an MWL query to retrieve data from the worklist. Enter a filter field, a filter string, and a channel field below.

Search Key

This setting is only visible if you select Patient, Study, or Series above.

Enter a key that you want to search for, for example, an instance Unique Identifier (UID), series UID, patient UID, or enter an asterisk (*) to search for all items. Enter a string.

Modality

This setting is only visible if select Study or Series above.

Enter a modality in short form that you want to search for, for example, CT, MRI, US, or enter an asterisk (*) to search for all modalities. Enter a string.

Filter Field

This setting is only visible if you select Worklist above.

Define a field of the worklist that you want to filter for:

• Station AET
• Station Name
• Modality

Filter String

This setting is only visible if you select Worklist above.

Enter a string that you want to filter for, for example, a station name, station AET, modality, or an asterisk (*) to filter for all items.

Channel Naming

This setting is only visible if you select Worklist above.

Define which field you want to use to name the channels:

• Station AET
• Station Name
• Modality

Result Handling

Define what PRTG does with the sensor result:

• Discard result (default): Do not store the sensor result.
• Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file names are Result of Sensor [ID].txt, Result of Sensor [ID].Data.txt, and Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.

This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel 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 this sensor shows different channels:

• 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. PRTG stacks all channels with this unit 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.

Query Entry Time Avg.

The average query entry time

Query Entry Time Max.

The maximum query entry time

Query Entry Time Min.

The minimum query entry time

Total

The total number of items found

This channel is the primary channel by default.

Total Time

The total time of the C-FIND request or MWL query
