Percona Monitoring and Management 2.38.1

Release date: July 13, 2023
Installation: Installing Percona Monitoring and Management

Percona Monitoring and Management (PMM) is an open-source database monitoring, management, and observability solution for MySQL, PostgreSQL, and MongoDB.

Fixed issue

PMM-12293 - The upgrade to Grafana 9.2.20 in PMM 2.38 fixed critical security CVE-2023-3128 by changing the authentication mechanism to rely solely on the user's unique ID provided by the identity provider.

This change caused an authentication issue for second and subsequent connections to PMM using a Percona Account. With this PMM update, we are fixing this authentication issue to ensure that users can log back into PMM after an initial connection. Previously, this would fail with a "User already exists" error.

If you are using a third-party authentication provider and continue to see this issue, pass the GF_AUTH_OAUTH_ALLOW_INSECURE_EMAIL_LOOKUP=1 environment variable to the PMM container.

Alternatively, set the oauth_allow_insecure_email_lookup config key in the auth section of the grafana.ini file. Keep in mind that any changes you make to this file are lost when upgrading PMM, so make sure to manually update this file after each upgrade.
