# Overview VirtualMetric is a flexible and easy to use real-time telemetry data monitoring, change tracking, and inventory reporting software system. You can configure it and start monitoring your data streams in minutes without having to install any agents on the monitored servers. It provides complete visibility with its pre-configured set of over 800 performance counters and detailed inventory scanning. You can set alarms, analyze the performance, track changes, correlate various counters, generate reports, forecast usage trends, and do much more. VirtualMetric also supports many hardware manufacturers to troubleshoot physical server issues related to hard disks, processors, memory modules, etc. You can find the supported hardware models in the [Bare Metal Hardware](https://docs.virtualmetric.com/server-pre-configuration/bare-metal-hardware) section. Allowing the HTTP/HTTPS ports on the firewall is enough to start monitoring. VirtualMetric uses * the [WS-Man](https://www.dmtf.org/standards/ws-man) protocol to connect and monitor **Windows** servers * [VMware vSphere Web Services](https://www.vmware.com/support/developer/vc-sdk/) to connect and monitor **VMware servers** * the SSH protocol to connect and monitor **Linux** servers * the SNMP protocol to connect and monitor network devices servers You can find the details of these, and many other features, in the following chapters. Whatever your telemetry needs, vVirtualMetric has something to offer. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
