PRTG Manual: AWS ELB v2 Sensor

Permissions for the AWS API key

This sensor requires permissions for the AWS API key.

For more information, see the Knowledge Base: How do I set permissions for the Amazon Web Services (AWS) API key to use certain sensors in PRTG?

Credentials

This sensor requires credentials for AWS.

Load balancers

This sensor supports Application Load Balancer and Network Load Balancer.

Performance impact

This sensor has a low performance impact.

Pricing

Amazon can charge you based on the number of API calls that the sensor sends to the Amazon servers. For more information, see Amazon CloudWatch Pricing – Amazon Web Services (AWS).

Add Sensor dialog

It can take up to several minutes before objects appear in the Add Sensor dialog.

Scanning interval

This sensor has a fixed minimum scanning interval for performance reasons. You cannot use a shorter scanning interval. Consequently, shorter scanning intervals in the Monitoring settings are not available for this sensor.

• The minimum scanning interval of this sensor is 1 minute.
• The recommended scanning interval of this sensor is 5 minutes.

IPv6

This sensor supports IPv6.

ID

The ID of the AWS ELB load balancer that this sensor monitors.

Name

The name of the AWS ELB load balancer that this sensor monitors.

Type

The type of the AWS ELB load balancer that this sensor monitors.

Region

The region in which the AWS ELB load balancer runs.

For a list of regions that this sensor supports, see section Supported AWS Regions and Their Codes.

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.

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.

Active Connection Count

The number of concurrent active TCP connections

Active Flow Count

The number of concurrent flows

Consumed LCUs

The number of LCUs that the load balancer uses

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

ELB 4XX Count

The number of HTTP 4XX client error codes

ELB 5XX Count

The number of HTTP 5XX server error codes

Healthy Host Count

The number of targets that are considered healthy

New Connection Count

The number of new TCP connections

New Flow Count

The number of new flows

Peak Bytes

The highest average throughput

Processed Bytes

The number of bytes processed

Rule Evaluations

The number of rules processed

Target 4XX Count

The number of HTTP response codes generated by the targets

Target 5XX Count

The number of HTTP response codes generated by the targets

Target Connection Error Count

The number of connections that were not successfully established

Target Response Time

The response time of the target

TCP Client Reset Count

The number of RST packets sent from a client to a target

TCP ELB Reset Count

The number of RST packets generated by the load balancer

TCP Target Reset Count

The number of RST packets sent from a target to a client

Unhealthy Host Count

The number of targets that are considered unhealthy
