Feed: Planet MySQL; Author: Krunal Bauskar; Percona Monitoring and Management (PMM) is an effective tool in tracking stats of the running MySQL servers. Especially, the timelines capability helps users to get the picture of how the given stats changes over tenure of the workload. PMM official packages are not yet available on ARM but part of the PMM (importantly the stats collector aka exporter) could be compiled on ARM that would facilitate reporting stats of the MySQL instance running on ARM to PMM-Server there-by allowing it to track MySQL on ARM. Background Few days back Agustin from Percona tried compiling ... Read More

Feed: AWS Compute Blog. Author: Ben Peven. This post was contributed by Dnyanesh Digraskar, Senior Partner SA, High Performance Computing; Linda Hedges, Principal SA, High Performance ComputingIn this blog, we define and demonstrate the scalability metrics for a typical real-world application using Computational Fluid Dynamics (CFD) software from Siemens, Simcenter STAR-CCM+, running on a High Performance Computing (HPC) cluster on Amazon Web Services (AWS). This scenario demonstrates the scaling of an external aerodynamics CFD case with 97 million cells to over 4,000 cores of Amazon EC2 C5n.18xlarge instances using the Simcenter STAR-CCM+ software. We also discuss the effects of scaling ... Read More

A common question that most beginner MySQL users ask is “How do I see all of the users in my MySQL server?” Most of them assume that there is a show users command in MySQL, but there isn’t one.
