Simplifying the Monitoring of Multi-Hypervisor Infrastructures Over the years, many enterprises have achieved tremendous cost reductions and management simplicity through virtualizing their IT infrastructure. According to Gartner, while some firms have virtualized over 90% of their servers, on an average, most firms have over 75% of their servers in a virtualized infrastructure, indicating the growth and maturity of the x86 server virtualization market. VMware dominated the virtualization market for several years but organizations are now also adopting other hypervisors such as Microsoft Hyper-V, Citrix XenServer, Oracle VM Server, Red Had Virtualization, etc. Additionally, the Kernel-based Virtual Machine (KVM) is an alternative for handling virtualization in Linux environments. And, the advent of hyper-converged infrastructures has introduced new hypervisors such... (more)

The Diverse Alerting Needs for Application Performance Monitoring

In today’s digital economy, most business services rely on IT applications. The increasing dependency on applications has resulted in the growing adoption of application performance monitoring (APM) solutions. The goals of an APM solution are: To ensure high application uptime, service reliability and great end-user experience To proactively diagnose performance problems so the respective stakeholder (application owner, IT Ops, DevOps, developer, etc.) can fix them before users notice them. Modern APM solutions must not only have deep monitoring functionality, but they must also... (more)

Synthetic Monitoring: A Key Component of Application Performance Monitoring Strategy – Part 1

As businesses have become increasingly reliant on IT, monitoring the end-user experience has become paramount. Whether applications are web-based, client-server (i.e., thick clients), or use thin client technologies (using technologies like Citrix, Microsoft Remote Desktops, virtual desktops, etc.), end-users need fast and seamless experience, and application performance has to be top-notch to deliver superior performance. Conversely, poor user experience has a catastrophic effect on the business: A 1 second increase in page load time for Amazon translates into a 1% drop in sale... (more)

Citrix Logon Simulator: A Must-Have for Citrix Administrators

Slow logon is one of the most common complaints from Citrix users. Due to the multitude of steps involved and the inter-dependencies between various tiers in the logon process, logon slowness is a difficult problem for Citrix administrators to detect and resolve. Citrix logon performance can be monitored in two ways: Passively, by observing real user logons and tracking the time taken to logon, as well as a breakdown of where time is being spent Actively, by simulating logons periodically to a Citrix farm, determining if logon succeeds and how long it takes Both approaches comple...
