Description

Real-time performance monitoring (RPM) enables you to configure active probes to track and monitor traffic across the network and investigate network problems. You can use RPM with EX Switches and this KB provides sample configurations.

Symptoms


Solution

To configure RPM services, include the rpm statement at the [edit services] hierarchy level.

Topology for the following sample configurations:
 
Probe                                       Target
  EX1 ------------------------------  EX2 (loopback0:37.1.1.1)


Configuring the Probe

The probe statement defines the owner name and test name used as identifiers for the probe. Together, they represent a single RPM configuration instance. When you specify the test name, you also can configure the test parameters. To configure the probe owner, test name, and test parameters, include the probe statement at the [edit services rpm] hierarchy level.

Here is an example using probe types, udp-ping and icmp-ping: 

root@EX1# show services rpm
probe probe1 {                    # probe owner #
    test probe_test1 {            # test name #
        probe-type udp-ping;      # test parameters #
        target address 37.1.1.1;
        test-interval 10;
        destination-port 49160;
    }
}
probe probe2 {                    # probe owner #
    test probe_test2 {            # test name #
        probe-type icmp-ping;     # test parameters #
        target address 37.1.1.1;
        test-interval 10;
    }
}

Configuring the Server

The TCP and UDP probes are proprietary to Juniper Networks and require a receiver to receive the probes. To configure the server to receive the probes, include the probe-server statement at the 'edit services rpm' hierarchy level.

Here is an example. 
root@EX2# show services rpm
probe-server {
     udp {
         port 49160;
     }
}
NOTE: This port number should be same as the value of 'destination-port' from the Probe configuration.

Here are sample outputs: 
root@EX1# run show services rpm probe-results
    Owner: probe1, Test: probe_test1
    Target address: 37.1.1.1, Probe type: udp-ping, Test size: 1 probes
