# RMon Use Case

## Main Goal

The goal is to have a fast data plotter / monitor for a distributed control system accessible only remotely via multiple ssh jumps

- The UI will run locally on the operator pc on a modern Linux
- The Data will be accessed remotely
- The operator can choose to record some of the data for history review

## Use case

- The data are acquired at different frequency from a distributed system in a private network
- The access to the data are different, some examples include:
  - CSV file
  - UDP streams
  - Specific software (e.g. EPICS)
  - ...
- Timestamp could be different for each case, e.g.:
  - for CSV could be as string %Y.%m.%d %H:%M:%S
  - for UDP a u64
  - etc
- Some signal are accessed in a push mode (e.g. udp) and some in pull (e.g. CSV) mode
- Each signal could have the following info:
  - Scale, offset
  - Unit
  - Label
  - Sampling period
- Data could be stored, two option:
  - continuos storage (from user start to user stop, data are kept if not explicitly required)
  - loop storage (only last N:M hours, N:M specified from user)
- The user will access the signals from a UI on his local machine (mostly linux, but windows also possible)
- The user UI should be a portable executable with limit dynamic dependencies
- In the UI the user can:
  - have multiple plots
  - have multiple cursors
  - make measurements and maths on the signals
  - hide/show signals
  - explore the list/tree of available signals and get info on them
  - request to store siganls
  - request historical data
  - drag and drop to add signals
  - signal plot style can be personalised
