Universal Device Poller - Define what should be calculated by the transform

Define formulas

Transforms are defined using basic algebraic operations and exponents. Available pollers serve as variables.

Type a formula for calculating the transform into the Formula field or use the Add Function button.

For frequently used formulas, see Universal Device Poller - common calculations for poller transforms

In formulas, you can use the following items:

• Standard mathematical operations

Example: {poller1}+{poller2}

• Mathematical constants e and π, as E() and PI(), respectively
• Poller transformation formulas are also nestable.

Example: avg(min({poller1},{poller2}),max({poller3},{poller4}))
The example returns the average of two poller comparisons.

Add a function

1. Click Add Function, and select an algebraic function.
2. Click within the function parentheses.
3. Click Add Poller, and select the poller that should be used in the calculation.

   Insert poller names within the parentheses of the selected function.

   If a selected function operates on multiple pollers, add all pollers within the parentheses, separate them by a comma and a single space.

   Example: avg({poller1}, {poller2}, {poller3})
