[RAD-6136] Script to Set Unreliable Data Points to Default Value

[francisco-cruz-o]

Description

RAD-6136
This ticket will create a script that will identify Unreliable data points that meet certain criteria and set the value of those data points to a specific value.

A sample script for identifying all unreliable points is found here:
https://github.com/MangoAutomation/script-examples/blob/main/mango-javascript/unreliable-data-source.js

A rough example of how this can be done via a Gralljs script is here:
https://github.com/MangoAutomation/script-examples/tree/main/check-and-set-unreliable

This script will:

• Be run on a schedule via Advanced Schedules
• Will not hold locks on data points in the runtime longer than necessary
• Will skip any data points that are:
  • In a Persistent TCP/gRPC data source
  • Not numeric data points

Identify:

• If a point is Running
• If a point is unreliable
• If the point has not received an updated value in a specific time period (at least 1 minute)
• Set the value of the numeric data point to the default value
  • This value will be stored in the TSDB database
  • This cannot change a data point from Unreliable to Reliable

Current behavior

• No Scripting for Set Unreliable Data Points to Default Value

Expected behavior

• Scripting for Set Unreliable Data Points to Default Value

Changes

• create script to:
  • Detect numeric data points marked as "unreliable"
  • Check if they haven't received an update for at least 1 minute
  • Set their value to a default (e.g. -1.0)
  • With this rules:
    • Skip points in Persistent TCP/gRPC data sources
    • Skip non-numeric data points
