lhcstatus2 posts on mastodon and twitter.

lhcstatus2 data as JSON: vistars.json
JSON Schema: vistars.schema.json
JSON Code on GitHub

Status data is read from CERN's vistar pages:
Page1
Configuration
Operation
Cryogenics

Feel free to use JSON output as you wish, with one request:
Use the next property to determine timeout, or refresh no quicker than once every 30 seconds.

Downtime and small errors are rare but may happen.

The unit property (in schema) follows https://dataprotocols.org/units/

experiment->operation: Floating point data may contain NaN. This could break certain JSON parsers.

experiment->config: Given as strings, not numbers/integers, may contain things like "no_value(V)", "-".
Luminosity dimensions are skipped.

cryo->state: An array containing one array for each colour bar on the lhc2 page. Each element represents a cryomodule/cryostat.
Possible values 0, 1, 2, 3; 0 = green, 1 = red, 2 = orange, 3 = blue
Orange indicates a state between red and green, for example one which is close to recovering.
Blue ? (only seen for CMS so far).
FYI: The CMS solenoid and ATLAS toroid & solenoid may lose cryogenic conditions without affecting the beam.
