VCP-VVF Administrator Study Guide: Objective 4.3 – VVF: Operate, Monitor Applications Using VCF Operations – Part 15

By | Last Updated:

Another post today, to keep working on a VMware Certified Professional – VMware vSphere Foundation Administrator (2V0-16.25) study guide series! We follow the official VMware Blueprint for the exam – VMware vSphere Foundation Administrator (PDF). This section is part of the upcoming VCP-VVF Study Guide Page, which will be released as a PDF when completed—check it out at https://www.vladan.fr/vcp-vvf-administrator/.

Today, we’re continuing with Objective 4.3 – VVF: Operate, focusing on Given a scenario, monitor applications using VCF Operations – Part 15. In VMware vSphere Foundation (VVF) 9.0, VMware Cloud Foundation (VCF) Operations, powered by VMware Aria Operations, provides tools to monitor application performance across virtual machines (VMs) and Kubernetes workloads in the Software-Defined Data Center (SDDC).

Monitoring applications ensures optimal performance, quick issue detection, and compliance with service-level agreements (SLAs). This objective is critical for the 2V0-16.25 exam, testing your ability to use VCF Operations to monitor application metrics and troubleshoot issues. Building on our previous posts (Objective 4.2, Parts 1-4, covering VVF management tasks, and Objective 4.3, Parts 1-14, covering VCF Operations setup, monitoring, dashboards, log analysis, costing, integrations, vSAN monitoring, and policies), we’ll provide hypothetical guide to monitoring applications using VCF Operations, practical insights, and exam-focused guidance using a realistic scenario, aligned with VMware’s official vSphere 9.0 and VCF 9.0 documentation (https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/9-0.html and https://techdocs.broadcom.com/us/en/vmware-cis/vcf/vcf-9-0-and-later/9-0/infrastructure-operations.html). Let’s dive into application monitoring with VCF Operations!

Why Monitoring Applications with VCF Operations Matters

In VVF 9.0, VCF Operations enables application-level monitoring by collecting metrics from VMs and Kubernetes pods, such as CPU usage, memory consumption, and application-specific performance indicators. This ensures administrators can detect bottlenecks, optimize resource allocation, and maintain SLA compliance for critical applications like databases or web servers. Objective 4.3 tests your ability to monitor applications in scenarios involving performance troubleshooting or SLA validation. This chapter (Part 15) focuses on a scenario involving application monitoring, complementing Part 14 (VCF Operations policies) and Part 13 (vSAN monitoring).

Not sure whether this would be at the exam.

Monitoring Applications Using VCF Operations

Below, we detail the process for monitoring the performance of “DB-App” (database VMs) and “Web-App” (Kubernetes pods) using VCF Operations, identifying performance issues, and recommending corrective actions. The steps are verified against VMware vSphere 9.0 and VCF 9.0 documentation (https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/9-0/vsphere-monitoring-and-performance.html and https://techdocs.broadcom.com/us/en/vmware-cis/vcf/vcf-9-0-and-later/9-0/infrastructure-operations.html).1. Accessing VCF Operations for Application Monitoring

Monitoring Applications Using Open Source Telegraf

You can use open source Telegraf to monitor application services and operating systems on a or Linux platform or on a Windows platform. More details in the documentation.

Quote:

Telegraf uses input plugins (where the metrics come from) and output plugins (where the metrics go) in the configuration files. You can see all the supported plugins at Plugin Directory. Input and output plugins should be written in the Telegraf configuration file and configuration directory. The Telegraf configuration file (telegraf.conf) lists all available Telegraf plugins.

  • onitoring-and-performance.html.Scenario Example: Recommend increasing vCPUs for “DB-App” VMs, adjusting pod resources for “Web-App”, and verifying SLA compliance.

    A. Deploy new Kubernetes pods
    B. Monitor performance metrics for VMs and Kubernetes workloads
    C. Configure vSAN disk groups
    D. Manage NSX firewall rules
    Answer: B. Monitor performance metrics for VMs and Kubernetes workloads.
  2. How do you monitor a database application in VCF Operations?
    A. Use Explore Logs to filter application events
    B. Navigate to Environment > Inventory > Virtual Machines and check response time and CPU metrics
    C. Edit VM settings in vCenter
    D. Create a vSAN storage policy
    Answer: B. Navigate to Environment > Inventory > Virtual Machines and check response time and CPU metrics.
  3. A Kubernetes pod shows “CrashLoopBackOff” in VCF Operations. What should you do?
    A. Disable vSAN services
    B. Check pod logs with kubectl and adjust resource limits
    C. Reinstall the ESXi host
    D. Disable DRS in the cluster
    Answer: B. Check pod logs with kubectl and adjust resource limits.

 

Final Words

Monitoring applications using VCF Operations in VMware vSphere Foundation 9.0 is essential for ensuring performance, detecting issues, and maintaining SLA compliance in the SDDC. Stay tuned for the next part of Objective 4.3 or 4.2! Happy studying, and good luck on your VCP-VVF journey!
