How Cirrus works
Cirrus obtains its log extracts using log show, in a command of the form
log show --predicate 'subsystem == "com.apple.clouddocs" OR subsystem == "com.apple.cloudkit" OR subsystem == "com.apple.mmcs" OR processImagePath CONTAINS[c] "cloudd" OR processImagePath CONTAINS[c] "bird" OR processID = 0’ --style json --info
for the time period specified by the Start and End .
This returns the log entries in JSON format, which are then parsed entry by entry to create a styled attributed string containing all the log entries in sequence.
