Documentation forServer & Application Monitor
Monitoring your applications and environment is a key capability of Hybrid Cloud Observability and is also available in a standalone module, Server & Application Monitor (SAM). Hybrid Cloud Observability and SAM are built on the self-hosted SolarWinds Platform.

Download Speed Monitor

This component monitor measures the time it takes to download data from the target node, and reports the speed in KB/s (1024 bytes per second). The target node must be running a Character Generator service.

For an overview about component monitors, see Work with SAM component monitors.


The statistic for this component monitor is the download speed in KB/s (1024 bytes per second).

Field descriptions


A default description of the monitor. To override the default description, add to or replace existing text. Changes are automatically saved. The variable to access this field is ${UserDescription}.

Customize descriptions to specify what will be monitored so related alerts and notifications are more meaningful later.

Enable Component

Determines if the component is enabled. Disabling the component leaves it in a deactivated state that does not influence its application availability or status, as displayed in the SolarWinds Platform Web Console.

Port Number

The port used for the character generator service. The default value is 19.

Download Sample Size (kb)

The amount of data in kilobytes (kb) you want to download from the node for testing the download speed.

Convert Value

Select the Convert Value check box to open the Formula box. From here, you can manipulate the returned value with a variety of mathematical possibilities. You can choose common functions from the drop-down lists to manipulate the returned value, or you can select the Custom Conversion option. See Convert values in data transformations for SAM component monitors for more information.

Response Time Threshold

Set the warning and critical threshold conditions based on the response time. The response time is the time in milliseconds it takes SAM to determine that a component is not Down and to retrieve any statistical data. See Application Monitor Thresholds.

Statistic Threshold

Specify when a threshold that indicates a warning or critical level was breached. Logical operators are in the drop-down followed by a blank field for you to enter the value of this threshold. For example: Less than 15 for warning, Less than 5 for critical. See Application Monitor Thresholds.

User Notes

Add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
