VMware Monitoring

Sign Up Now

Discover and monitor VMware infrastructure.

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

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.

Know when your CPU usage starts to spike or when your host starts swapping memory pages to the disk.

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.

VMware monitoring 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.

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.

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.

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.

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, Twitter DMs 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.

Monitor 100 ESX/ESXi hosts or VMs for just $89/month.

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.

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.

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.

Build custom Plugins and see the data you need.

Expanding list of integrations.


Plugins are supported in all these various flavors.

Debian, Ubuntu, CentOS, RedHat, Madriva, Fedora, and Suse

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.

Troubleshoot problems with hardware health.

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

List of Basic monitors:

Server (One Server, irrespective of CPU/RAM, is a Basic Monitor)

Amazon Web Services


List of Advanced monitors:

Select from over 50+ out-of-the-box plugins. You can also write custom plugins. 25 custom metrics per plugin included. One plugin is free per Server. Additional plugin on Server will be accounted as one additional Basic Monitor.

List of Advanced monitors:

Network monitoring licensing is purely based on the number of interfaces that are monitored. It is mandatory to have at least one active interface in order to monitor a device. While ten performance counters per device can be monitored for free, every additional ten is counted as one interface.

Premium support includes email, community, chat and phone.

List of Advanced monitors:

Every webpage that is loaded in the browser is considered as a page view, irrespective of the number of resources that are loaded behind. For example, for a single page to load, there are various resource calls for images, css, etc, which are not counted in page views. Only the webpage that the user visits is counted as page views.

Credits are auto-refilled every month, however left over refilled credits are not carried forward to the next month.
