VMware vFabric tc Servers

Monitored Parameters

IT360 monitors the VMware vFabric tc Server and the Spring applications deployed on the server to detect any performance problems. This monitoring is carried out by tracking critical components of the vFabric tc Server such as memory, thread, throughput, garbage collector,etc.

The Availability tab shows the availability history of the vFabric tc Server for the past 24 hours or 30 days. The Performance tab shows some key performance indicators of the vFabric tc Server such as CPU utilization, throughput and garbage collection rate. This tab also shows the health status and events for the past 24 hours or 30 days.

The List view lists all the vFabric tc Servers monitored by IT360 along with their overall availability and health status. It enables you to perform bulk admin configurations. Click on the individual monitors listed to view detailed performance metrics.

To view detailed performance metrics of a vFabric tc Server, click on the monitor name listed in the Availability or List View tabs. The performance metrics have been categorized into 6 different tabs:

Overview

This tab provides a high-level overview of the health and performance of the vFabric tc Server along with information pertaining to the throughput, thread and garbage collection.

Parameters
