defining node
polling hostname or ip address: This is the address (hostname or IP address) of the device you would like to poll with Orion (Router, switch, server, ect).
polling method: most devices -- This is the method you'd like to use to poll the device - SNMP, ICMP, WMI, ect - Generaly, you'll want to use SNMP and WMI.
snmp version 2c (default) -- SNMP v1 or v2c are fine here unless you are concerned about enhanced security regarding SNMP - then you'll want to configure and use v3.
snmp port? -- The default is fine here unless you decide on another port while configuring your devices.
community string: -- This is your SNMP community string - it's essentialy a password required to send "get" commands to your devices for polling - you can configure both read and write community strings if you'd like. If a write string is configured, that means commands can be executed remotely on the device and this may pose an additional security risk for you.
read/write community string: Community string used to poll the device(s).
i cant add a node yet since i do not know what to put in.. and when i test it fails. - You'll have to configure SNMP on the devices before you can poll them with Orion. Depending on what type of device(s) you have, there are many different ways to do this. If you provide details on some of the devices, we can help you get SNMP configured on them.
and if i click a discovered node i have this on the dash board:
virtual memory consumption in esx host = data is not available - Configuring SNMP on ESX requires you to run remote CLI commands either using the locally installed application or via the virtual remote CLI appliance. Here is the VMware KB for configuring SNMP: VMware vSphere 4 - ESX and vCenter Server
Note: You'll want to get your vCenter added into Orion first before you manually add the ESXi hosts as it will automatically grab the hosts once the vCenter is added.
virtual machine cpu consumption = Same as above - you'll get this info once you have SNMP configured.
vm network traffic = Same as above - you'll get this info once you have SNMP configured.
unknown machine type = What kind of device is this? Orion doesn't have support for every single vendor/device out there but it's possible that someone has created some custom pollers that you can import in and use to gather additional details about the device via Orion.
router interfaces cannot be seen - SNMP will need to be configured on the routers/switches - Here is a Cisco guide on configuring SNMP: Cisco IOS Configuration Fundamentals Configuration Guide, Release 12.2 - Configuring SNMP Support [Cisco IOS Software Releases 12.2 Mainline] - Cisco Systems
If you're using a different vendor's switch, please post which kind and we can help you out.
node detail: Unsupported or unkown device - may have to use custom pollers here.
thanks
