    Configuring SNMP Traps for JunosV App Engine

    SNMP-based management and monitoring of the JunosV App Engine infrastructure is implemented using the Juniper Networks proprietary MIB jnx-jvae-infra-mib. CLI configuration statements are provided to specify thresholds for low storage (disk) space, high processing load, and low free memory conditions on the compute node. SNMP traps are raised when the values exceed or fall below these thresholds.

    To enable this SNMP-based monitoring, two CLI configurations are required:

    • You must define at least one system as the recipient of the SNMP traps (that is, configure the trap-group statement).
    • You must enable the subagent to connect to router.

    To create an SNMP trap group:

    1. Create and name a group of SNMP traps.
      set snmp trap-group -group-name
    2. For each trap group that you define, you must include the targets statement to define at least one system as the recipient of the SNMP traps in the trap group. Specify the IPv4 or IPv6 address of each recipient, not its hostname.
      set snmp trap-group group-name targets address
    3. Configure other optional statements as required to define the type of traps in the trap group and the behavior of the traps.

    You also must configure the Agent-X TCP port so the subagent can connect to the router.

    To enable the subagent to connect to router:

    • Configure the subagent statement at the [edit snmp subagent] hierarchy level.
      set snmp subagent tcp routing-instance default

    This command allows connections over the default routing instance.
