Exam 2V0-21.23 topic 1 question 30 discussion

The resxtop and esxtop command-line utilities provide a detailed look at how ESXi uses resources in real time. The fundamental difference between resxtop and esxtop is that you can use resxtop remotely, whereas you can start esxtop only through the ESXi Shell of a local ESXi host.

I answered C & E on the test, passed with 428.

It says "wants to observe near real-time statistics" C and E are real time. not 'near real time" Advanced Performance charts are "near real time" and Overview performance charts include display the metrics for an object in the inventory. - keyword 'object in the inventory" where as "The metrics provided in Overview performance charts are a subset of those collected for hosts and the vCenter Server" https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-monitoring-performance/GUID-FF7F87C7-91E7-4A2D-88B5-E3E04A76F51B.html

Question is about a "A vSphere environment" the term generally encompasses the entire setup managed by VMware vSphere, which includes both the vCenter Server and the ESXi hosts. Then there is spoken about: "near real-time" A: Advanced Performance Charts: Advanced Performance Charts, accessible through the vSphere Client, provide detailed performance metrics for VMs, including near real-time statistics. These charts offer granular data that can help administrators identify and diagnose performance issues such as CPU contention. E: esxtop: esxtop is a command-line tool that provides real-time performance monitoring for ESXi hosts. It displays detailed information about CPU, memory, disk, and network usage for all VMs and helps identify performance bottlenecks, including CPU contention. esxtop is highly regarded for its ability to give administrators deep insights into the current state of the system.

Let me ask, the questions asks about Vsphere reporting tools. Could C&E be accessed within Vsphere? If not, wouldnt the answers be A and D? Which two vSphere reporting tools could the administrator use? (Choose two.) A. Advanced Performance Charts B. esxcli C. resxtop Most Voted D. Overview Performance Charts E. esxtop Most Voted

Tricky question... depends a lot on the interpretation. You need to select 2 tools, but are esxtop and resxtop seen as 2 different tools or just one. They want to see near real-time statistics, but what is near real-time. If 20 second intervals are still fine answer A would be valid.

C&E https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-monitoring-performance/GUID-A31249BF-B5DC-455B-AFC7-7D0BBD6E37B6.html The resxtop and esxtop command-line utilities provide a detailed look at how ESXi uses resources in real time

AE .esxtop, Advanced Performance Charts both are vsphere reporting tools

Other than esxtop, Advanced Performance Charts also provide the analysis of CPU contention issues.

A is defintely correct...

i voted C&E. Advanced performance charts for cpu (ready and usage counters) are only for esxi’s cpu, but we can only view the same counters individually for every vm’s in their monitoring tab. Only esxtop and resxtop are displaying the cpu counters for all the vms of a host in a single view

The correct answers are A and E. Advanced Performance Charts and esxtop are both vSphere reporting tools that can be used to observe near real-time statistics for all VMs. Advanced Performance Charts provides a graphical view of performance data, while esxtop is a command-line tool that provides more detailed information. B, C, and D are incorrect answers. B, esxcli, is a command-line tool that is used to manage ESXi hosts. C, resxtop, is a command-line tool that is used to monitor the performance of ESXi hosts. D, Overview Performance Charts, provides a graphical view of performance data, but it does not provide near real-time statistics.
