Old Favorites, New Tricks: MySQL Monitoring After MEM

The MySQL Plug-in for Oracle Enterprise Manager has been generally available since October 23, 2026. This post sets the GA release against the two products it follows: MySQL Enterprise Monitor, which reached end of life in January 2025, and Oracle's own Enterprise Manager plug-in for MySQL, which now carries a deprecation notice. What came back from MEM (backup monitoring, a full advisor catalog, a version end-of-life check), what it adds to Oracle's plug-in (query history, a disaster-recovery verdict for InnoDB ClusterSet), what is new, and how to run both plug-ins side by side while you move.

You Moved SQL Server to Linux. Why Is Your Monitoring Still on Windows?

You Moved SQL Server to Linux. Why Is Your Monitoring Still on Windows?

Most SQL Server monitoring still reaches for Windows to do its job: WMI for host metrics, a Windows agent to run the collection, a domain account to authenticate it. The SQL Server Plug-in for Oracle Enterprise Manager collects all 78 of its metric groups with T-SQL from a Linux agent over port 1433. How host metrics come from SQL Server's own views, how availability groups behave under Pacemaker, and what works differently on Linux.

Now Generally Available: MySQL, SQL Server, and Db2 Plug-ins for Oracle Enterprise Manager

The MySQL, Microsoft SQL Server, and IBM Db2 plug-ins for Oracle Enterprise Manager are generally available, each with one build for Oracle EM 24ai and one for 13.5. Here are one or two features from each release: Query Analyzer and InnoDB ClusterSet disaster-recovery promotion readiness for MySQL, Query History with Query Store plan regression and Security Update Status for SQL Server, and HADR takeover readiness and blocking chains for Db2. Also covered: how to move from the Open Beta, where to find us at Oracle AI World (Booth #7024, October 25–28), and the November 10 webinar on the SQL Server plug-in.

Jaeger 2.0 and the Next Chapter of AI Observability

Jaeger 2.0 and the Next Chapter of AI Observability

AI is changing observability less by adding a chatbot to the dashboard than by forming a feedback loop: agents that help write instrumentation, open standards that carry GenAI traces, and agents that investigate the results. How Jaeger v2's rebuild on the OpenTelemetry Collector, the GenAI semantic conventions, OllyGarden's Rose, and Observe's AI SRE fit that loop, and what Jaeger's roadmap adds next.

Security and Policy Enforcement in OpenTelemetry: What Works Today, and Where It Stops

The OpenTelemetry Collector can now enforce real rules about which monitoring data is kept, cleaned, routed, and signed, and OpenTelemetry eBPF Instrumentation (OBI) can connect existing logs to the requests behind them with no code changes. What each component enforces today, why the coming policy format fails open, where trace IDs and OBI stop, and how to protect the Collector itself.

OpenTelemetry Solved Vendor Lock-In. Now It Has to Solve Fragmentation.

Almost every major observability platform now accepts OpenTelemetry data, but few handle it the same way once it arrives. A compatibility matrix scores ten offerings, from Grafana Cloud to Dynatrace, across twelve areas of the OpenTelemetry ecosystem. Why the specification and its implementations drift apart, what each offering contributes, and the twelve things useful compatibility evidence should contain.

Is This Database Slower Than Last Month? Workload History and the Agent-Local History Store

Is This Database Slower Than Last Month? Workload History and the Agent-Local History Store

pg_stat_statements counts everything since its last reset, which answers what is expensive overall but not what changed this week. Workload History snapshots those counters into a per-target store on the Enterprise Manager agent and replays them over any window you choose, from the whole workload down to one statement. Wait-event sampling adds what each statement was waiting on, and the Retention Policies page sets how long each kind of history is kept. Part four of four on the advisory features in the PostgreSQL Plug-in for Oracle Enterprise Manager.

Why Isn't Autovacuum Keeping Up? The Vacuum Advisor and the xmin Horizon

Why Isn't Autovacuum Keeping Up? The Vacuum Advisor and the xmin Horizon

When a table keeps growing while autovacuum is running, the cause is usually one of three things: the table's own storage parameters moved its trigger point, cleanup runs too rarely for the churn, or something is holding the transaction horizon so no vacuum can remove dead rows. The Vacuum Advisor recomputes each table's trigger point from its effective settings, estimates avoidable growth with pgstattuple, names whatever is holding the xmin horizon with the command that releases it, and tracks transaction-ID age against the wraparound limit. Part three of four on the advisory features in the PostgreSQL Plug-in for Oracle Enterprise Manager.

This Week in OpenTelemetry: September 25, 2026

GitHub brought OpenTelemetry export to the Copilot app and AWS launched CloudWatch Omni on top of it, both on September 22. The 2026 Prometheus/OpenTelemetry interoperability survey shows the two getting measurably easier to run together, JavaScript SDK 3.0 is scheduled for September 30, and the GenAI semantic conventions keep moving. Plus a closer look at profiling, where the eBPF profiler is turning the alpha Profiles signal into working software.
