CloudWatch
datus cloudwatch reads AWS CloudWatch through boto3. Global usage:
datus cloudwatch [--profile <env>] <group> <subcommand> [args...]
--profile (before the group) selects the configured environment; add -o json
to any command for machine-readable output (tables show a curated subset).
Everything here is read-only except alarms set-state.
Logs
datus cloudwatch logs groups [-p /aws/glue] [--limit N]
datus cloudwatch logs streams <group> [--order-by LastEventTime|LogStreamName] [--limit N]
datus cloudwatch logs get <group> <stream> [--limit N] [--start-from-head]
datus cloudwatch logs tail <group> [--filter 'ERROR'] [--since 15m] [--follow] [--limit N]
datus cloudwatch logs insights <group>... -q '<query>' --start -1h [--end now] [--limit N]

Metrics
datus cloudwatch metrics list [--namespace AWS/Lambda] [--name Errors]

--stat is one of Average/Sum/Minimum/Maximum/SampleCount; -d Name=Value adds
a dimension (repeatable).
Alarms
datus cloudwatch alarms list [-p prefix] [--state ALARM]
datus cloudwatch alarms get <name>
datus cloudwatch alarms history <name> [--limit N]
datus cloudwatch alarms set-state <name> --state ALARM|OK|INSUFFICIENT_DATA [--reason TEXT]
set-state is for testing composite alarms or temporary suppression — it does
not change the alarm definition and the next evaluation overwrites it.
