# Installing SNMP

Before starting OpUtils, it is advisable to check if your system or the systems to be monitored are SNMP enabled.

## For checking SNMP in Windows OS

1. Go to Start -> Settings -> Control Panel -> Administrative Tools -> Services
2. Check for SNMP Service.
3. If SNMP Service does not exist, install SNMP. To do so, read the [Installing SNMP on Windows](https://www.manageengine.com/products/oputils/help/snmpinstallation/install_snmp_win.html) section.
4. If **SNMP Service** is displayed but the status of the Service is not displayed, double click on SNMP Service and click on **Start** to start the Service. You can also choose to start the service manually or automatically.

## For checking SNMP in Linux

1. Execute any one of the command in the console:

   ```
   $ /etc/rc.d/init.d/snmpd status
   ```

   or

   ```
   $ service snmpd status
   ```

2. If SNMP is installed, but is not started, execute any one of the command in the console to start SNMP (as root):

   ```
   $ /etc/rc.d/init.d/snmpd start
   ```

   or

   ```
   $ service snmpd start
   ```

3. If SNMP is not installed, install SNMP. To do so, read the [Installing SNMP on Linux](https://www.manageengine.com/products/oputils/help/snmpinstallation/install_snmp_linux.html) section.
