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.

i_betaThis 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.

i_square_cyanFor 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.

Multi-platform probe

You can add this sensor to a multi-platform probe.

Basic Sensor Settings

Setting

Description

MAC Address

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

i_round_redPRTG 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.

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.

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 sensor result and the last response 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

Admin Status

The admin status

  • Up status: Enabled
  • Down status: Unknown
  • Unknown status: Disabled

Client Count

The number of clients

i_round_blueThis channel is the primary channel by default.

Clients with Poor SNR Count

The number of clients with a poor signal-to-noise ratio (SNR)

i_round_redThis 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

i_round_blueThis channel has default limits:

  • Upper error limit: 90%

Total Rx Utilization

The total percentage of receive utilization across all slots in the access point

i_round_blueThis channel has default limits:

  • Upper error limit: 90%

Total Channel Utilization

The total percentage of channel utilization across all slots in the access point

i_round_blueThis channel has default limits:

  • Upper error limit: 90%
