While NMIS ships with a set of default Groups built-in, most users will want to add custom groupings. Groups are single level and cannot be nested. Therefore, it is imperative some thought and consideration be given to the creation of groups and assignment of nodes. If you plan to use opMaps you should consider creating Groups based on a specific geographic location. Otherwise, Group definition is most often defined by device type (Routers, switches, etc), business function (core, perimeter, offsite, etc), or manufacturer (Cisco, Juniper, etc).
...
Once you have completed adding your group, click the Add button to confirm or Cancel to close the dialogdialogue box. The NMIS Configuration window will open, centered centred on the group_list, to allow you to confirm the change. When you are satisfied simply close this window.
...
Each node requires, at a minimum, 4 attributes to be set. These are marked with a red asterisk next to the properties name , and are the first four properties in the Add/Edit Nodes and Devices window.
- From the NMIS Menu select System Setup > Add/Edit Nodes and Devices
- Enter a name for the new node, note: NO SPACES IN THE NAME, caps are OK
- Enter an IP address or resolvable name for the device
- Select the appropriate value for "Group",
- Enter the SNMP Community * string; this defaults to "public", but may be customized in your network
- Under Extra Options
- Select the appropriate value for "Net Type" (wan WAN or lanLAN)
- Select the appropriate value for "Role Type" (core, distribution, or access)
- Select one of the two options below to either monitor by Ping or SNMP
...
- Under the Advanced Options section, set "Collect" to "false"
- Scroll to the botton button and click "Add and Update Node"
- You should now be able to find your device on the main NMIS8 page, selecting the device should show the node status as reachable, type as generic and model as PingOnly
...
- Under the Advanced Options section, ensure "Collect" is set to "true"
- Set the "SNMP Community" column to the community string for that daemon, if you don't have one then it's time to make one up or use NMIS' default "nmisGig8"
- Scroll to the botton button and click "Add and Update Node"
- Ensure your device is running an SNMP Daemon service that will allow the community string you specified access
- If SNMP is not configured you will likely see the Node Status as degraded and an Event that says "SNMP Down - SNMP error, Escalate 0, active", if you configured the email you will now also have an email in your inbox regarding the problem
...
...
- System -> System Configuration -> Contacts
- Click "edit" on the Contact1 line
- Do not change the name, leave it as Contact1
- Set your email address, and other fields if you like
- Click the "edit" button to save
- To test the email run the command <nmis_base>/admin/testemail.pl
By default, NMIS8 has the user Contact1 notified on all events for the first couple of escalation levels (0 and 2), because we set the email address for Contact1 emails will start to flow immediately, no changes need to be made. After you receive the first couple of messages you may find yourself wanting to make some modifications to the default settings, see INSERT LINK HERE.
