Affected: 3.57.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.57.0

1. Check installed version

apt-cache policy monitoring || rpm -q monitoring || monitoring --version

2. No fixed release: DOWNGRADE to a release before 3.57.0 (Debian / Ubuntu)

apt-cache madison monitoring sudo apt install monitoring=<VERSION_BEFORE_3.57.0> sudo apt-mark hold monitoring

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list monitoring sudo dnf downgrade monitoring-<VERSION_BEFORE_3.57.0> sudo dnf versionlock add monitoring

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
