PRTG Manual: AWS EC2 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.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a low performance impact.

Lookups

This sensor uses lookups to determine the status values of one or more channels.

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

ID

The ID of the AWS EC2 instance that this sensor monitors.

Name

The name of the AWS EC2 instance that this sensor monitors.

Region

The region in which the AWS EC2 instance 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 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.

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.

This channel is the primary channel by default.

Disk Read

The disk read speed

Disk Read Ops

The number of disk read operations

Disk Write

The disk write speed

Disk Write Ops

The number of disk write operations

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.
