Documentation forServer & Application Monitor
Monitoring your applications and environment is a key capability of SolarWinds Observability Self-Hosted (formerly Hybrid Cloud Observability) and is available in the Essentials edition. Server & Application Monitor (SAM) is also available in a standalone module.

Available data transformations for SAM component monitors

SAM provides a number of predefined data transformation functions that may be applied to one or more component monitors to generate mathematically manipulated results.

The following table lists available transformation functions:

Data Transformation Syntax Definition

Euler’s Number

 E()

Euler’s number, also called "the number e," is defined as the base of the natural logarithm as the limit of a certain sequence, or as the sum of a certain series.

Pi

 Pi()

Pi is the mathematical constant whose value is the ratio of any circle's circumference to its diameter.

Rounding

Round({value}, {number of decimal places})

Provides a number that is rounded to the specified number of decimal places.

Truncate

Truncate({value},{number of decimal places})

Truncates a monitored value to a designated number of decimal places.

Square Root

 Sqrt({value})

Provides the square root of a given number.

Exponentiation

 Pow({base value}, {exponent value})

Provides the result from repeated multiplication of the base number.

Temperature: Celsius to

Provides the number of TB, originally presented in GB

Terabyte to Kilobyte

 TeraToKilo({value})

Provides the number of KB, originally presented in TB

Terabyte to Megabyte

 TeraToMega({value})

Provides the number of MB, originally presented in TB

Terabyte to Gigabyte

 TeraToGiga({value})

Provides the number of GB, originally presented in TB

Nest multiple data transformations

To apply multiple data transformations, you can nest them within each other.

For example, if a value is originally presented in bytes and you want to convert it to gigabytes, and then truncate the results, you can use the following transformations together:

  • X to Gigabyte
  • Truncate

The format for X to Gigabyte would be XToGiga({value})

If you add Truncate to the transformation, the format would be Truncate(XToGiga({value}),{number of decimal places})

In most cases “{value}” would be replaced by ${statistic} for a SAM component monitor so the ending format would be:

Truncate(XToGiga(${statistic}),{number of decimal places})
