Configure Probes

Probes measure key performance metrics to specific endpoints, aiding in path selection and determining Layer 3 Circuit Reachability.
Where Can I Use This?
What Do I Need?
  • Prisma SD-WAN
  • Active Prisma SD-WAN Subscription
  • Physical and virtual ION devices running software version 6.4.1 and higher.
Prisma SD-WAN supports always-on probing, enabling measurement of key metrics such as round trip latency, packet loss, jitter and other metrics to any ICMP/DNS/HTTP/HTTPS service across all transports (Direct, Fabric, Standard VPN). These results are available to the administrator and serve in making path selection decisions with precise control using performance policy. Furthermore, the system can utilize the same application health probes to determine L3 Reachability. At the tenant level, you can configure probes by specifying the probe type, endpoints, and frequency.
Probe Profiles
, which are global objects containing probe configurations, are defined at the tenant level and linked to Circuit Categories and Circuits.
Probe Configs
are created with parameters such as Protocol Type (ICMP, DNS, HTTP, HTTPS), EndPoints (IP/FQDN/URL), Frequency, Probe Cycle Duration, and Path Type (Direct, Standard VPNs, Prisma SD-WAN VPNs).
  1. To configure
    Probe Profiles
    , go to
    Manage
    Resources
    Probes
    Probe Profiles
    .
    View the list of configured probe profiles and their configurations. Use the
    Actions
    options to
    Edit
    a probe profile, view the
    Audit Logs
    , or any system configuration changes and remove a probe profile. To add a new
    Probe Profile
    :
    1. Select
      Add New Probe Profile
      and enter a
      Name
      for the profile and optionally,
      Description
      and
      Tags
      .
    2. From the
      Probe Configs
      drop down, select a probe profile. You can select up to 8 probe configs for a probe profile. The default probe configs are:
    3. Save
      your changes.
    The system automatically applies default probe profiles to all circuit categories, while default probe configurations are disabled by default for existing tenants. You can't remove a default probe profile, but you have the option to delete a default probe configuration.
  2. To configure
    Probe Configs
    , go to
    Manage
    Resources
    Probes
    Probe Configs
    .
    View the list of configured probe configurations and their details. Use the
    Actions
    options to
    Edit
    a probe config, view the
    Audit Logs
    or any system configuration changes. To add a new
    Probe Config
    :
    1. Select
      Add New Probe Config
      . For existing tenants, the default Probe Configs will be present in Disabled mode. However, for new tenants, they will be in Enabled mode by default.
    2. Enter a
      Name
      for the probe config and optionally,
      Description
      and
      Tags
      .
    3. Enter an
      IP address
      or
      FQDN
      for the probe configuration.
    4. Select the
      Probe Cycle Duration
      to be in minutes or seconds. The minimum value is 1 second and the maximum value is 60 minutes. The results of the probe are used in path selection (in combination with an SLA) and will trigger flow moves for existing flows and avoidance for new flows if the defined SLA is not being met.
    5. Enter the
      Probe Count
      value as a multiple of the probe cycle duration; multiples of 1, 2, and 3 are accepted.
    6. Select the
      Probe Path Type
      as Direct, Prisma SD-WAN VPN, and Direct VPN.
    7. Select the Protocol as,
      • HTTP
        : Enter the
        HTTP Response Code
        from the drop-down and the
        HTTP Response String
        .
      • HTTPS
        : Enter the
        HTTPS Response Code
        from the drop-down and the
        HTTPS Response String
        .
      • DNS
        : Enter the
        DNS Server IP address
        .
        The IP / FQDN address will be used as the PTR / DNS record lookup criteria.
      • ICMP
    8. Save
      your changes.
