Basic Tutorial

This brief tutorial will walk you through the major features of NetMRG. The tutorial assumes that you have installed the Net-SNMP daemon on a system which you want to monitor.

1. Create a new group.
   1. Click on Admin tab, and select the Devices option to display the root groups list.
   2. Click on Add.
   3. In the Name textbox, enter a name for your group, such as "Home."
   4. In the Comment textbox, enter a description for your group, such as "Computers in my house."
   5. In the Parent drop down box, select -Root- as we want this device in the root of the device tree. You can create nested groups.
   6. Click the Save Changes button to create your new group.
2. Create a new device.
   1. Click on the name of your new group. You are now looking at an (empty) list of devices and subgroups in your new group.
   2. Click on Add in the Monitored Devices section.
   3. Click on Create a new device.
   4. In the Name textbox, enter a name for your device, such as "My Server."
   5. In the IP or Host Name textbox, enter a domain name or IP address of your device. Domain names must be resolvable from your monitoring host.
   6. In the SNMP Support dropdown, select the appropriate version. If unsure, select SNMPv1.
   7. In the SNMP Read Community textbox, enter the SNMP community string for your device.
   8. Click the Save Changes button to create your new device.
3. Create a new sub-device.
   1. Click on the name of your new device. You are now looking at an (empty) list of sub-devices in your new device.
   2. Click on Add.
   3. In the Name textbox, enter "System." This will be a pseudo-sub-device used for monitoring the device as a whole.
   4. In the Type drop down box, ensure that Group is selected.
   5. Click the Save Changes button to create your new "System" sub-device.
4. Add graph templates.
   Since devices running Net-SNMP are common, NetMRG comes with several graph templates for commonly used variables.
   1. Click on the Apply Templates icon () for your new "System" sub-device (hover to see captions).
   2. Select one or more of the "Linux Box" template graphs from the list.
   3. Click on the Save Changes button to apply the template.
5. View your new graphs.
   1. Click on the Tree option in the Reporting tab.
   2. Click on the name of your group to expand it.
   3. Click on the graph icon () beside your device (orange graphs mean there are graphs associated with this device, black means there are no graphs attached to this device.
   4. You should now see graphs! If you don't, you may need to wait for the gatherer to perform another cycle.
