VMware Monitoring

Discover and monitor VMware infrastructure.

Monitor resource utilization across datacenter, clusters, resource pools, ESX/ESXi hosts and virtual machines.

Keep track of VMware performance counters.

Gather metrics on compute, memory, disk, datastore, and network resources for both your virtual hosts and VMs.

Get alerted for a host of metrics.

Receive instant alerts for metric-level changes and threshold breaches through differnt modes, along with incident details.

Monitor over 50+ applications with Site24x7 Plugins.

Monitor Apache Tomcat, MySQL and 50 other applications running on your VMs, with our out-of-the-box plugins support.

Monitor your vSphere environment with Site24x7.

Automatically discover and map your entire vSphere environment, from data center to virtual machines (VMs), in real time with vCenter APIs. Get a complete performance management console for your entire server infrastructure - both physical and virtual.

Monitor cluster and resource pools.

Site24x7 makes cluster resource management easy. View an aggregate summary of all computing and memory resources available for each individual cluster. Analyze active resource consumption, and manage the resource pool partition to ensure adequate resource allocation for all your VM groups.

Auto Discover and Categorize Virtual Resources

Oversee vCPU provisioning.

Manage vCPU allocation to avoid overcommitting physical CPU cores to VMs. Analyze long-term CPU workloads for your ESX/ESXi hosts and plan CPU to vCPU ratio for maximum performance.

ESX/ESXi Host CPU Utilization

Monitor CPU usage at the VM level.

Measure active CPU usage for each guest VM and compare that usage with other VMs on the same host to benchmark CPU consumption. Measure the amount of time a VM remained offline or was ready to run but incurred delay due to vCPU contention, and increase the number of vCPUs to manage that VM's application workload.

VM CPU Utilization

Identify host memory contention.

Excessive ballooning or swapping can degenerate the performance of applications running on your VMs. Set thresholds to monitor VM memory swap usage and high balloon memory utilization. Analyze your VM count and host memory usage to identify the events that triggered host memory reclamation.

VM Memory Utilization Counters
Metric-level Thresholds

Set individual thresholds for each VMware counter and metric.

Versatile Alerting

SMS, email, voice calls, push notifications via Android and iOS apps, and RSS feeds.

Out-of-the-box Reports

View top VMs and top ESX/ESXi hosts reports by CPU, memory, disk and network utilization.

Alarms View

View all down/trouble alerts pertaining to your VMware environment along with incident details.


Interactive graphs with real time performance metrics of virtual resources.


Integrate with team software like Slack, HipChat, PagerDuty and more.

SLA Management

Define SLAs for your ESX/ESXi hosts, VMs and track their compliance.


Monitor your virtual resources on the go.

Analyze memory usage and overcommitment.

Monitor your memory overcommitment strategy, constantly analyze the consumed host memory for your ESX/ESXi servers and active guest memory of all virtual machines, and reduce memory size to free up unused memory for other VMs.

ESX/ESXi Host Memory Utilization

Analyze network utilization and performance.

List all available physical (NIC) and virtual (VNIC) network interface controllers, along with other network devices present on your vSphere environment. Identify a baseline for your network performance by monitoring network usage and bandwidth at the host (ESX/ESXi) and VM level. Monitor virtual network traffic on each virtual machine and set thresholds to identify drops in the data transmit rate.

VM Network performance

Identify disk I/O bottlenecks.

Manage storage performance by analyzing virtual and physical disk usage for each VM and ESX/ESXi host. Measure utilization metrics, guest disk I/O details for each virtual disk partition, read and write speed statistics, latency associated with physical disk volumes, and virtual disk (VMDK) files.

Disk I/O Usage of Hosts and VMs

Identify datastore contention.

Analyze I/O performance metrics by measuring latency and read and write speeds for every host and VM connected to the datastore. Set thresholds to identify ESX/ESXi hosts with high I/O bandwidth usage and VMs with latency issues. Identify whether you have too many VMs or poor disk performance.

Disk I/O Performance

Troubleshoot problems with hardware health.

Monitor the health of ESX/ESXi host hardware components such as CPU processors, memory, fans, temperature, voltage, and power.

ESX/ESXi Host Hardware Components Status
