Fluctuations in network usage within organizations can occasionally surge due to several factors. For instance, increased traffic might stem from activities such as large-scale promotional campaigns, sudden software updates or patches, escalated remote work demands, or even unforeseen security incidents. An article published by the Financial Express claims e-commerce order volumes spiked by 23% in 2023 during Black Friday sales on the Unicommerce platform.
To boost network resiliency and avoid network downtime during a spike in network usage, organizations need hyper scalability. This can be achieved by expanding their digital footprint across hybrid clouds, data centers, and virtual machines. But expanding your IT infrastructure across cloud environments can be tedious.
An efficient approach to hyperscale is to deploy virtual server machines in your enterprise network. However, effectively managing these virtual servers and host machines is not easy without a virtual server management software that monitors the critical metrics of different virtual servers.
Critical metrics that need to be monitored in a virtual server
Virtual environments comprise various components, such as virtual machines, host machines, data stores, and clusters, that demand continuous monitoring. Understanding and monitoring critical metrics in a virtual machine are essential for network admins to ensure optimal performance and troubleshoot issues in virtual machine (VM) environments.
Several critical metrics that should be monitored closely within a virtual server include:
Memory ballooning: Used to optimize memory usage.
VM health: Tracks the overall health status of the virtual machines.
Memory swapping: Used to transfer memory pages to a critical VM.
Data store availability: Ensures accessibility and availability of data stores.
VM network connectivity: Monitors and maintains connectivity between VMs.
Challenges faced by network admins to monitor virtual machines
Virtualized environments often consist of numerous VMs across various hosts and platforms. Managing this complexity, ensuring seamless connectivity, and monitoring diverse VMs can be daunting. Here are some challenges network admins encounter when monitoring virtual machines:
VM Sprawl: VM sprawl refers to the uncontrolled proliferation of virtual machines in an IT environment. It’s caused by the rapid and unregulated creation of virtual machines, often resulting in an excess of underutilized virtual machines.
Resource allocation and optimization: Balancing resources among VMs to prevent bottlenecks or resource shortages while optimizing performance requires continuous monitoring and fine-tuning.
Zombie VMs: Zombie VMs are dormant or abandoned virtual machines that remain active within an IT infrastructure, consuming resources without fulfilling any purpose.
Tracking these instances, and managing their life cycle is an ongoing challenge for network admins. Incorporating a reliable virtual server management tool like ManagerEngine OpManager, helps network admins overcome challenges as this solution monitors virtual machines in their IT infrastructure with ease.
