IAS alarm GUI

Actually the IAS provides a basic GUI displaying a table of alarms implemented in PySide6.

The purpose is mainly to support development and test.
In operation the GUI

• need to be more sophisticated showing, for example, the topology of the system
• must be able to run from everywhere i.e. outside of the contorl network (use case: the responsible of a system sitting in HQ want to check the alarms active in one of the instruments); ALMA developed a web alarm interface for that

The actual GUI is composed of a simple table of alarms with pause/resume capabilities. It gets the alarms from the kafka topic.

An API to ACK alarms in python is available.

This discussion is to propose and prioritize improvements to the IAS alarm GUI.

IAS alarm GUI improvements

• Color table entries by alarm priorities
• ACK
  By sending a commmand to the IAS core through kafka; maybe not in the first release but the acking shall allow to ACK dependents alarms with one single user action
• Shelve
  Shelving is based on time (i.e. auotmatically disabled after the shelving time elapses); the GUI shlall allow the user to shelve an alarm from a drop list of times; note that some alarms cannot be shleved (ftrom configuration)
• Filtering
  Useful for showing alarms for a given part of the system. Categories of users could be allowed to browse only a subset of alarms
• Sorting by priorities, status and time
• login
  (basic: opertaor can read and ACK alarms; all the others read only)
• Show icons for color blind
  icons must be different for all the states of all the priorites of the alarms
• Play sound
  actually the IAS allows to define one sound for each priority but it should IMO also allow to set a sound to each alarm so to tell directly to the operator what a problem is without moving is head in front of the alarm panel
