# Prerequisites for Hardware Monitoring

It is essential to monitor the hardware components of various critical devices in your network to ensure continuous service availability and network uptime. **OpManager**, the advanced [hardware monitor](https://www.manageengine.com/network-monitoring/hardware-monitoring.html), supports monitoring the hardware status of the servers and network devices in your environment from vendors such as Cisco, Juniper, HP, Dell, Palo Alto, Huawei and others. It monitors various important hardware parameters such as voltage, temperature, power, fan speed, processors, etc., via SNMP for your network and server devices (including HyperV host) and via vSphere for VMware ESX/ESXi hosts. **OpManager** offers in-depth server and hardware monitoring functionality for your network.

## Check if SNMP is installed:

It is mandatory that SNMP is enabled in the corresponding devices as OpManager primarily uses SNMP to query device status and metrics. To install SNMP agent in a Linux device, follow [these](https://www.manageengine.com/network-monitoring/help/install-snmp-linux.html?hwmonpreq) steps.

## Prerequisites for Servers:

OpManager supports hardware monitoring of HP, Dell, Supermicro and Fujitsu servers. The prerequisites for the corresponding categories are mentioned below.

### HP:

If Hardware Sensor Monitors are not displayed, then please make sure that these tools are installed on the monitored server:

- HP Insight Server Agents
- HP Insight Foundation Agents
- HP Insight Storage Agents

### Dell:

If Hardware Sensor Monitors are not displayed, then please make sure that **Dell OpenManage** has been installed on the monitored server.

### Supermicro:

Supermicro's **SuperDoctor agent** has to be installed on the monitored server to monitor the hardware metrics.

### Fujitsu:

Fujitsu's **ServerView agent** must be installed on the monitored server to monitor hardware metrics.
