esxtop and resxtop are both performance monitoring tools for VMware environments, but their primary difference lies in how they are accessed. esxtop is run directly on the ESXi host's command line, while resxtop is a remote version, typically used through the vSphere Management Assistant (vMA) or vCLI, allowing monitoring from a remote system. 

Detailed Explanation:

esxtop:

Runs directly on the ESXi host's command line (ESXi Shell). 

Requires direct access to the ESXi host's console. 

May not be accessible in all environments, especially where direct SSH access to ESXi hosts is disabled. 

resxtop:

A remote version of esxtop. 

Typically used through the vSphere Management Assistant (vMA) or vCLI. 

Provides a more secure way to monitor ESXi hosts remotely. 

Can be used when direct access to the ESXi host's command line is restricted or not available. 

Requires installation of vMA or vCLI. 

Functionality:

Both esxtop and resxtop display the same performance metrics for CPU, memory, network, disk, and power management. 

They offer similar interactive commands to navigate and filter the displayed data. 

They can be used to troubleshoot performance issues by identifying bottlenecks in the system. 

In essence, resxtop provides the same functionality as esxtop but allows for remote access, making it a more convenient and often preferred option for monitoring ESXi hosts, especially in production environments where direct access is limited or restricted.

Top 10 high-level EC2 scenario-based questions to challenge your AWS & DevOps skills

 Here are 10 high-level EC2 scenario-based questions to challenge your AWS & DevOps skills 1. Your EC2 instance is running but you can’t connect via SSH. What troubleshooting steps will you take?  Check Security Group inbound rules (port 22 open to your IP).  Verify Network ACLs (NACLs not blocking inbound/outbound).  Confirm instance’s Public IP / Elastic IP.  Validate Key Pair and correct permissions on .pem.  Ensure SSM Agent is installed (Session Manager can help).  Check system logs on the console for OS-level issues. 2. You terminated an EC2 instance by mistake. How can you prevent this in the future? Enable Termination Protection in EC2 settings. Use IAM permissions to restrict TerminateInstances. Tag critical instances and set resource policies. 3. Your EC2 instance needs to access an S3 bucket securely. What’s the best way to configure this? Best practice: Attach an IAM Role with least privilege policy to the EC2 instance. Avoid hardcoding...

GitOps-Driven Management of VKS Clusters: Enabling GitOps on VCF 9.0 (Part 03)

  GitOps-Driven Management of VKS Clusters: Enabling GitOps on VCF 9.0 (Part 03) In the Part-02 blog, we walked through the process of deploying an Argo CD instance within a vSphere Namespace on  VMware Cloud Foundation (VCF) 9.0 , enabling a GitOps-based approach to manage Kubernetes workloads in a vSphere environment. With Argo CD successfully installed, we now have a powerful toolset to drive declarative infrastructure and application delivery. In this blog post, we’ll take the next step by demonstrating how to  provision and manage VKS clusters  directly through the Argo CD  UI and CLI . This allows us to fully operationalise GitOps within the private cloud, delivering consistency, scalability, and automation across the Kubernetes lifecycle. Importance of Managing the Kubernetes Cluster with a Gitops Approach Adopting a GitOps-based approach for managing Kubernetes clusters enables declarative, version-controlled, and automated operations by leveraging Git a...
