PRTG Manual: LDAP Sensor

Sensor Name

Enter a name to identify the sensor.

Parent Tags

Shows 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:

• ldapsensor

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 ().

Connection Security

Define if the sensor uses an SSL/TLS-secured connection to the LDAP server:

• Use LDAP without connection security (default)
• Use LDAP over SSL

If you select Use LDAP over SSL, you need to enter a DNS name in the settings of the parent device. The sensor does not work with an IP address.

Port Selection

Define if you want to use a default port or a custom port for the connection to the LDAP server:

• Use default port (default): Use the default port. This is port 389 for unsecure connections and port 636 for secure connections.
• Use custom port: Use a custom port. Specify the Port below.

Port

This setting is only visible if you select Use custom port. Enter a custom port for the connection to the LDAP server. Enter an integer.

Distinguished Name

Enter the distinguished name (DN) that you want to authenticate against the LDAP server. Usually, this is the information for the user that you want to authenticate with. For example, use the format cn=Manager,dc=my-domain,dc=com for a DN on an OpenLDAP server.

Password

Enter the password for the Distinguished Name.

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 in percent.

Response Time

The response time in msec

This channel is the primary channel by default.
