Oracle Enterprise Manager vs Percona Monitoring and Management

Oracle Enterprise Manager 24ai manages Oracle Database and Engineered Systems across data centers and cloud environments. It supports real-time and historical database diagnostics, tuning, issue analysis, change validation and automated migrations. Teams can monitor Oracle and non-Oracle technologies, configure static or adaptive threshold alerts, and manage incidents and notifications. It covers Oracle Exadata and Zero Data Loss Recovery Appliance, as well as Oracle applications, WebLogic Server on Kubernetes and third-party middleware. Database management spans on-premises systems, OCI, AWS, Azure and Google Cloud. Security tools support fleet assessments, sensitive-data discovery, compliance tracking, secure-configuration audits and automated remediation. Dynamic Runbooks can guide troubleshooting with notes, charts, SQL or operating-system commands; an Enterprise Manager app can display metric data in Grafana. The platform can run on premises or through OCI Marketplace. Enterprise Manager 24ai requires Oracle Database. Base features are included with an Oracle software license or support contract; some packs and options require separate appropriate licenses. Oracle does not state a plan price on the product page.

Percona Monitoring and Management (PMM) is a free, open source tool for monitoring, managing, and observing databases and the servers they use. It covers MySQL, PostgreSQL, MongoDB, and deployments across on-premises, cloud, and hybrid environments. Dashboards, configuration insight, and Query Analytics support monitoring; Query Analytics ranks queries by load and provides anomaly investigation, explain plans, and customizable dashboards. Percona Advisors scan MySQL, MongoDB, and PostgreSQL databases for security gaps, misconfigurations, and performance problems, then offer recommendations. PMM includes backup and restore for MongoDB and MySQL, with scheduled or on-demand backups and point-in-time recovery. Percona Alerting is described as supporting more than 15 notification channels. Deployment options include Docker, Podman, a virtual appliance, Kubernetes or OpenShift via Helm, and an AWS Marketplace instance. PMM Server has a browser-accessible interface; its documented Docker setup recommends at least 2 CPU cores, 4 GB RAM, and 100 GB disk, and requires x86-64-v2 CPU support. PMM Client connections to the server use TLS over HTTPS.
