Monitoring Nodes in the Fabric
As an administrator or operator, you can use Junos Space to track the status of physical and logical components of deployed nodes in a fabric.
Junos Space Network Management Platform supports SNMP Monitoring by an SNMP Manager for SNMP v1, v2c, and v3.
The SNMP manager polls Junos Space to obtain information about the logical components of the nodes using an object identifier (OID) in SNMP v1 and v2, or v3 as a user. The response is provided by the Junos Space SNMP agent and the polled data is displayed in the Network Monitoring workspace.
This topic contains the following sections:
Viewing and Modifying the SNMP Configuration for a Fabric Node

LM-SENSORS-MIB is not supported by the Junos Space virtual appliance, but only by the Junos Space Appliance. Therefore the threshold settings of CPU Max Temp (mC), CPU Min Fan (RPM) and CPU Min Voltage (mV) will not trigger any traps in the virtual appliance.
Junos Space supports RAID-related traps on a Junos Space appliance. The following is a sample trap:
40948 Normal [+] [-] 2/4/13 09:54:14 [<] [>] space-node 10.205.56.38 [+] [-] uei.opennms.org/generic/traps/EnterpriseDefault [+] [-] Edit notifications for event Received unformatted enterprise event (enterprise:.1.3.6.1.4.1.8072.4 generic:6 specific:1001). 1 args: .1.3.6.1.4.1.795.14.1.9000.1="One or more logical devices contain a bad stripe: controller 1."

To add a third-party SNMP V1 or V2c manager on a fabric node:
Adding a Third-Party SNMP V3 Manager on a Fabric Node
To add a third-party SNMP V3 manager on a fabric node:
The trap settings for the SNMPv3 manager are not automatically updated in Network Monitoring. Therefore, to ensure that the Network Monitoring receives the traps from Junos Space, you must add the same settings manually in the /opt/opennms/etc/trapd-configuration.xml file. Table 7 displays the mapping between the parameters in the /opt/opennms/etc/trapd-configuration.xml file and the fields in the Add 3rd Party SNMP Manager page.
The following is a sample configuration in the /opt/opennms/etc/trapd-configuration.xml file.
<?xml version="1.0"?> <trapd-configuration snmp-trap-port="162" new-suspect-on-trap="false"> <snmpv3-user security-name="JunosSpace" auth-passphrase="auth-password" auth-protocol="MD5"/> <snmpv3-user security-name="JunosSpace" auth-passphrase="auth-password" auth-protocol="MD5" privacy-passphrase="privacy-password" privacy-protocol="DES"/> </trapd-configuration>
