How to query cloudwatch logs using boto3 in python

Question

I have a lambda function that writes metrics to Cloudwatch. While, it writes metrics, It generates some logs in a log-group.

INFO:: username: simran+test@abc.co

I used awslogs. if you install it, you can do. --watch will tail the new logs.

awslogs get /aws/lambda/log-group-1 --start="5h ago" --watch

You can install it using

pip install awslogs

to filter you can do:

awslogs get /aws/lambda/log-group-1  --filter-pattern '"ClinicID=7667"' --start "5h ago" --timestamp

It supports multiple filter patterns as well.

awslogs get /aws/lambda/log-group-1  --filter-pattern '"ClinicID=7667"' --filter-pattern '" username=simran+test@abc.com"' --start "5h ago" --timestamp
