PRTG Manual: Cisco WLC Access Point Overview Sensor

<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Cisco WLC Access Point Overview Sensor

The Cisco WLC Access Point Overview sensor monitors the operational status of a wireless LAN controller (WLC) access point and provides a sum of various network utilization metrics of the available slots.

This sensor is in beta status. The operating methods and the available settings are still subject to change. Do not expect that all functions work properly, or that this sensor works as expected at all.

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
Enabled Beta Sensors experimental feature	This sensor requires that the Beta Sensors experimental feature is enabled. For more information, see the Knowledge Base: What are beta sensors and how can I use them?
Credentials	This sensor requires credentials for SNMP in settings that are higher in the object hierarchy.
Performance impact	This sensor has a very low performance impact.
Lookups	This sensor uses lookups to determine the status values of one or more channels.
Scanning interval	The recommended scanning interval of this sensor is 5 minutes.

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

cisco
snmp
wlc

For more information about basic sensor settings, see section Sensor Settings.

Cisco WLC Access Point Specific

Setting	Description
MAC Address	The MAC address of the access point that this sensor monitors. PRTG shows this value for reference purposes only. We strongly recommend that you only change it if the Paessler support team explicitly asks you to do so. Wrong usage can result in incorrect monitoring data.
Name	The name of the access point.
Number of Slots	The number of available slots in the access point.

Setting

Description

MAC Address

The MAC address of the access point that this sensor monitors.

PRTG shows this value for reference purposes only. We strongly recommend that you only change it if the Paessler support team explicitly asks you to do so. Wrong usage can result in incorrect monitoring data.

Name

The name of the access point.

Number of Slots

The number of available slots in the access point.

Sensor Display

Setting	Description
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.

Description

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.

Debug Options

Setting	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. 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.

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.

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.

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

For more information, see section Inheritance of Settings.

Channel List

Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Channel	Description
Admin Status	The admin status Up status: Enabled Down status: Unknown Unknown status: Disabled
Client Count	The number of clients This channel is the primary channel by default.
Clients with Poor SNR Count	The number of clients with a poor signal-to-noise ratio (SNR) This channel is only available for the Cisco 5500 series.
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
Operational Status	The operational status Up status: Associated Warning status: Disassociating, Downloading Down status: Unknown
Total Tx Utilization	The total percentage of transmit utilization across all slots in the access point This channel has default limits: Upper error limit: 90%
Total Rx Utilization	The total percentage of receive utilization across all slots in the access point This channel has default limits: Upper error limit: 90%
Total Channel Utilization	The total percentage of channel utilization across all slots in the access point This channel has default limits: Upper error limit: 90%
