Configuring Basic RPM Probes

To configure basic RPM probes, you must configure the probe owner, the test, and the specific parameters of the RPM probe.

For ICMP ping, ICMP ping timestamp, UDP ping, and UDP ping timestamp probes, you can also set a timestamp to improve the measurement of latency or jitter. The probe is timestamped by the device originating the probe (the RPM client).

In this sample use of RPM, basic probes are configured for two customers: Customer A and Customer B. The probe for Customer A uses ICMP timestamp packets and sets RPM thresholds and corresponding SNMP traps to catch lengthy inbound times. The probe for Customer B uses HTTP packets and sets thresholds and corresponding SNMP traps to catch excessive lost probes. To configure these RPM probes:

  1. Navigate to the top of the configuration hierarchy in either the J-Web or CLI configuration editor.
  2. Perform the configuration tasks described in Table 228.
  3. If you are finished configuring the network, commit the configuration.
  4. Go on to one of the following procedures:

Table 228: Configuring Basic RPM Probes

Task

J-Web Configuration Editor

CLI Configuration Editor

Navigate to the Services>RPM level in the configuration hierarchy.

  1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
  2. Next to Services, click Configure or Edit.
  3. Next to Rpm, select the Yes check box.
  4. Click Configure.

From the [edit] hierarchy level, enter

edit services rpm

Configure the RPM owners customerA and customerB.

  1. In the Probe box, click Add new entry.
  2. In the Owner box, type customerA.
  3. Click OK.
  4. Repeat the previous steps and add an RPM probe owner for customerB.
  1. Enter

    set probe customerA

  2. Enter

    set probe customerB

Configure the RPM test icmp-test for the RPM owner customerA.

The sample RPM test is an ICMP probe with a test interval (probe frequency) of 15 seconds, a probe type of icmp-ping-timestamp, a probe timestamp, and a target address of 192.178.16.5.

  1. On the Rpm page, select customerA.
  2. In the Test box, click Add new entry
  3. In the Name box, type icmp-test.
  4. In the Test interval box, type 15.
  5. In the Probe type box, select icmp-ping-timestamp.
  6. Select the Hardware timestamp check box.
  7. In the Target box, select the Yes check box, and click Configure.
  8. In the Target type box, select Address.
  9. In the Address box, type 192.178.16.5.
  10. Click OK.
  1. From the [edit] hierarchy level, enter

    edit services rpm probe customerA

  2. Enter

    set test icmp-test probe-frequency 15

  3. Enter

    set test icmp-test probe-type icmp-ping-timestamp

  4. Enter

    set test icmp-test hardware-timestamp

  5. Enter

    set test icmp-test target address 192.178.16.5

Configure RPM thresholds and corresponding SNMP traps to catch ingress (inbound) times greater than 3000 microseconds.

  1. On the Probe page, select icmp-test.
  2. In the Thresholds box, select the Yes check box, and click Configure.
  3. In the Ingress time box, type 3000.
  4. Click OK.
  5. In the Traps box, click Add new entry.
  6. In the Value box, select ingress-time-exceeded.
  7. Click OK.
  1. Enter

    set probe customerA test icmp-test thresholds ingress-time 3000

  2. Enter

    set probe customerA test icmp-test traps ingress-time-exceeded

Configure the RPM test http-test for the RPM owner customerB.

The sample RPM test is an HTTP probe with a test interval (probe frequency) of 30 seconds, a probe type of http-get, and a target URL of http://customerB.net.

  1. On the Rpm page, select customerB.
  2. In the Test box, click Add new entry.
  3. In the Name box, type http-test.
  4. In the Test interval box, type 30.
  5. In the Probe type box, select http-get.
  6. In the Target box, select the Yes check box, and click Configure.
  7. In the Target type box, select Url.
  8. In the Url box, type http://customerB.net.
  9. Click OK.
  1. From the [edit] hierarchy level, enter

    edit services rpm probe customerB

  2. Enter

    set test http-test probe-frequency 30

  3. Enter

    set test http-test probe-type http-get

  4. Enter

    set test http-test target url http://customerB.net

Configure RPM thresholds and corresponding SNMP traps to catch 3 or more successive lost probes and total lost probes of 10 or more.

  1. On the Probe page, select http-test.
  2. In the Thresholds box, select the Yes check box, and click Configure.
  3. In the Successive loss box, type 3.
  4. In the Total loss box, type 10.
  5. Click OK.
  6. In the Traps box, click Add new entry.
  7. In the Value box, select probe-failure.
  8. Click OK.
  9. In the Traps box, click Add new entry.
  10. In the Value box, select test-failure.
  11. Click OK.
  1. Enter

    set probe customerB test icmp-test thresholds successive-loss 3

  2. Enter

    set probe customerB test icmp-test thresholds total-loss 10

  3. Enter

    set probe customerB test icmp-test traps probe-failure

  4. Enter

    set probe customerB test icmp-test traps test-failure
