Is there a way to generate the AWS Console URLs for CloudWatch Log Group filters?
04:01 22 Mar 2020

I would like to send my users directly to a specific log group and filter but I need to be able to generate the proper URL format. For example, this URL

https://console.aws.amazon.com/cloudwatch/home?region=us-east-1#logsV2:log-groups/log-group/
%252Fmy%252Flog%252Fgroup%252Fgoes%252Fhere/log-events/$3FfilterPattern$3D$255Bincoming_ip$252C$2Buser_name$252C$2Buser_ip$2B$252C$2Btimestamp$252C$2Brequest$2B$2521$253D$2B$2522GET$2B$252Fhealth_checks$252Fall$2B*$2522$252C$2Bstatus_code$2B$253D$2B5*$2B$257C$257C$2Bstatus_code$2B$253D$2B429$252C$2Bbytes$252C$2Burl$252C$2Buser_agent$255D$26start$3D-172800000

will take you to a log group named /my/log/group/goes/here and filter messages with this pattern for the past 2 days:

[incoming_ip, user_name, user_ip , timestamp, request != "GET /health_checks/all *", status_code = 5* || status_code = 429, bytes, url, user_agent]

I can decode part of the URL but I don't know what some of the other characters should be (see below), but this doesn't really look like any standard HTML encoding to me. Does anyone know a encoder/decoder for this URL format?
