Metrics & Logs support for IoT – Bringing Secure Monitoring and Logging to the Edge

Simple uptime monitoring for Internet-of-Things (IoT) is well-known and requires knowing if the devices are up and running. Having additional long-term performance data, secure (tamper-proof) logging at your Edge devices is only a tiny step when using Metrics & Logs. With our support for device, infrastructure, and application metrics as well as Syslog data, you …

Monitoring Azure Virtual Machines with Opvizor Metrics and Logs

It’s crucial to monitor Azure resources for availability, performance, and operation when you have key applications and business processes that rely on them. This article outlines the monitoring data created by Azure virtual machines (VMs), as well as how to analyze and alert on this data using the features of Opvizor Metrics and Logs. We …

How to Detect and Optimize NUMA in VMware Infrastructure?

NUMA (non-uniform memory access) is a memory architecture that supports multiprocessing where the memory access time is dependent on the memory location relative to the processor, and a CPU may access its own local memory quicker than non-local memory under NUMA. NUMA’s advantages are confined to specific workloads, particularly on servers where data is frequently …

VMware vSphere ESXi Memory Issues Can Slow Down the Virtual Infrastructure Performance

ESXi is the bare-metal hypervisor and the main component of VMware vSphere that is responsible to run Virtual Machines (VMs) on top of it. ESXi abstracts the underlying hardware resources from the physical server and allocates them to VMs to run workloads and applications. In ESXi hosts, everything is managed by VMKernel who decouples the underlying resources …

What is NUMA Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). The benefits of NUMA …
