Remark

Description

Sensor creation

You can create this sensor only on a probe device.

IPv6

Setting

Path

Enter the path of the folder that you want to monitor. For example, enter C:\Windows. The folder must exist on the probe system.

i_round_blueThe sensor only supports local paths.

Timeout (Sec.)

Enter a timeout in seconds. If the scan of the folder takes longer, the sensor cancels the request and shows an error message. If two consecutive scans fail, the sensor shows the Down status. The default value is 300 seconds (5 minutes). The maximum value is 1079 seconds (17 minutes and 59 seconds).

Recurse Subfolders

Specify if the sensor includes subfolders in the folder monitoring:

  • Do not recurse subfolders (default): Only monitor the folder. Do not monitor its subfolders.
  • Monitor the folder and its subfolders (recursive): Monitor the folder and all of its subfolders.
    i_round_redIf you recurse subfolders in large directories that have a high number of branches, this might cause timeout errors or performance issues.

Filter by File Name

Select if you want to filter by file name:

  • Disable (default): Do not filter by file name.
  • Include filter: The sensor counts files that match the File Filter.
  • Exclude filter: The sensor counts files that do not match the File Filter.

File Filter

This setting is only visible if you select Include filter or Exclude filter above.

Enter a comma-separated list of file names, file formats, or patterns you want to filter for. For example, '*.pdf, *.docx' includes or excludes files with the file formats .pdf or .docx.

i_round_blueThe file filter is not case-sensitive and supports wildcards (*).

Filter by File Age

Select if you want to filter by file age:

  • Disable (default): Do not filter by file age.
  • Enable: Filter by file age.

Newer Than

This setting is only visible if you select Enable above.

Enter a file age. The sensor only counts files that are younger than this age.

i_round_blueLeave this field empty if you only want to filter for files with the Older Than setting.

Older Than

This setting is only visible if you select Enable above.

Enter a file age. The sensor only counts files that are older than this age.

i_round_blueLeave this field empty if you only want to filter for files with the Newer Than setting.

File Age Filter Unit

This setting is only visible if you select Enable above.

Select the time unit that you want to use for Filter by File Age:

  • Days (default)
  • Hours
  • Minutes

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.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary 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.
    i_round_redYou 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.

Description

Result Handling

Define what PRTG does with the sensor result:

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

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

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

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 b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich 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

File Count

The number of files in the folder

i_round_redThe sensor counts all files in a folder, including hidden files.

i_round_blueThis channel is the primary channel by default.

Folder Count

The number of folders

Folder Size

The folder size

Newest File

The time since the newest modification of a file in the folder (newest file)

i_round_blueThe sensor shows a negative value if the date of a modified file is in the future.

Oldest File

The time since the oldest modification of a file in the folder (oldest file)
