* SNMP Port: The SNMP port to use.

5. Click on "Create".

Step 2: Create Data Sources

1. Click on the host you just added.
2. Click on "Data Sources".
3. Click on "Add".
4. Enter the following information:* Data Source Name: The name of the data source.
* Data Source Type: The type of data to collect.
* SNMP OID: The SNMP OID of the data to collect.

5. Click on "Create".

Step 3: Create Graphs

1. Click on the data source you just created.
2. Click on "Graphs".
3. Click on "Add".
