Use AWS CLI to query AWS CloudWatch Logs and determine the most recent entry into a Log Group
aws logs describe-log-groups | jq ".logGroups[].logGroupName" | grep -E "homeplus|mcdonalds" | xargs -n 1 -t aws logs describe-log-streams --query "logStreams[*].lastEventTimestamp" --log-group | jq "max/1000|floor" | xargs -t -n 1 date -r
# aws logs describe-log-groups | jq ".logGroups[].logGroupName"
# Get LogGroup names
# grep -E "homeplus|mcdonalds"
# (Optional) Filter LogGroup names
# xargs -n 1 -t aws logs describe-log-streams --query "logStreams[*].lastEventTimestamp" --log-group | jq "max/1000|floor"
# Get last event timestamp for each LogGroup.
