# When modifying this script, please also upstream to:
|
|
# https://github.com/strukturag/nextcloud-spreed-signaling/pull/480
|
|
#
|
|
# Creates a neutralized and simplified log from the HPB logs by:
|
|
# 1. Replacing "user sessions" with "userX"
|
|
# 2. Replacing "room sessions" with "sessionX"
|
|
#
|
|
# E.g. the following line:

# May 26 13:31:36 server nextcloud-spreed-signaling[726]: clientsession.go:425: Session tooJzGsaUllvfGXdh3-74-yjAt-L9gCQKrs_U-DlLkZ8PTBabmJub3J6bEFGNEV6UnRZdEl2ZHpvUnJKMDNtSkFxZHBxZWR1X3VWUkJuZWllc2VUNko0RTFxLURaRXJyYjJ6ckc4dFBJRVVhT0lOLWR5RGtCM1R2MFpRemd3ZUFSLU9qWDZkR3FEQjR6MGt6c3p0VG92NmhqeEFEQkotN1JHM0lnbHl2ODRlbVRDaUlnQlhFQ3M1U1U2MDl4eWc4SU5MR0xjdTlUa0xaSmJqWGJ8Njk4NzAxNTg2MQ== joined room token123 with room session id P9roBo5O0EnRR8N4r+64MMdSHO2tu2ffNqjtICwSG43AHWL3XKn6XYv9xdYCgUYufxiCzIvg/QQk7cv8Uda1uhyDgh1FLPLCdjUe4uHJWKXb31rHig3gm+FdvOEO3GHEcKlJyPtSZzTupiatpanalRvMi6xR3jIXYoGcuvc//R2gzKFYNZQKwGdXXLMHNNHTlHPSAqIoYyj3vo5B+BeG9G1zo9Pq1WC3Akr2dghASkc+KJTHtpT3NbFBCAAH7jH
