apilogs is a fork of the excellent
awslogs <https://github.com/jorgebastida/awslogs> project with specific customizations suited to querying and streaming logs for
Serverless APIs using
Amazon API Gateway <https://aws.amazon.com/api-gateway/> and
AWS Lambda <https://aws.amazon.com/lambda/>_.
Simply provide an API Gateway API ID and Stage name and
apilogs will automatically aggregate log events from all log streams for your API Gateway API as well as all Lambda function log streams attached to your API.
$ pip install apilogs
i.e. stream logs for your Serverless API: $ apilogs get --api-id xyz123 --stage prod --watch
Grep for errors one hour ago using credentials from AWS CLI profile "myprofile": $ apilogs get --api-id xyz123 --stage test2 --profile myprofile --aws-region us-east-1 --start='2h ago' --end='1h ago' | grep "ERROR"
Aggregate logs from across streams.
List existing groups
$ apilogs groups
List existing streams
$ apilogs streams /var/log/syslog
Watch logs as they are created
$ apilogs get /var/log/syslog ALL --watch
Human-friendly time filtering:
--start='2d ago' --end='1h ago'
Retrieve event metadata:
--timestampPrints the creation timestamp of each event.
--ingestion-timePrints the ingestion time of each event.

Note: You need to provide to all these options a valid AWS region using
AWS_REGION env variable.
While querying for logs you can filter events by
--start='2m'Events generated two minutes ago.
--start='1 minute'Events generated one minute ago.
--start='5 minutes'Events generated five minutes ago.
--start='2h'Events generated two hours ago.
--start='1 hour'Events generated one hour ago.
--start='5 hours'Events generated five hours ago.
--start='2d'Events generated two days ago.
--start='1 day'Events generated one day ago.
--start='5 days'Events generated five days ago.
--start='2w'Events generated two week ago.
--start='1 week'Events generated one weeks ago.
--start='5 weeks'Events generated five week ago.
Using specific dates:
--start='23/1/2015 12:00'Events generated after midday on the 23th of January 2015.
--start='1/1/2015'Events generated after midnight on the 1st of January 2015.
--start='Sat Oct 11 17:13:46 UTC 2003'You can use detailed dates too.

You can use
--filter-pattern if you want to only retrieve logs which match one CloudWatch Logs Filter pattern.
This is helpful if you know precisely what you are looking for, and don't want to download the entire stream.
For example, if you only want to download only the report events from a Lambda stream you can run::
$ apilogs get my_lambda_group --filter-pattern="[r=REPORT,...]"

Send a pull request and bug the maintainer until it gets merged and published. :).

Although, the most straightforward thing to do might be use
--profile, this will eventually become a pain in the ass.
