Baseline Your Prisma Access Hub Application and Link Performance

Baseline your Prisma Access Hub application and link performance before configuring SD-WAN link management profiles.
Before you Configure SD-WAN Link Management Profiles, Palo Alto Networks recommends you baseline your Prisma Access Hub application and link performance to better understand the normal payload activity for your Prisma Access Hub to avoid unnecessary link swapping for applications and traffic that do not require it.
  1. Select
    Panorama
    SD-WAN
    Monitoring
    and modify the SD-WAN monitoring time range.
    The longer the time frame you use to baseline your Prisma Access Hub app and link performance, the more accurate the baseline will be. At a minimum, use three days worth of app and link performance to baseline the latency, jitter, and packet loss data you use to create your SD-WAN link management profiles.
    Palo Alto Networks recommends assessing seven days of app and link performance data to baseline the latency, jitter, and packet loss for the Prisma Access Hub.
  2. Filter the SD-WAN monitoring to display only your Prisma Access Hub-Spoke VPN clusters.
    1. Click an App Performance or Link Performance summary that indicates Impacted, Error, or Warning counts to view a detailed list of sites and their status based on latency, jitter, and packet loss.
    2. In the VPN Cluster filter, select
      Prisma Access Hub-Spoke
      .
    3. Click a Site to view in-depth health details for the Prisma Access Hub.
  3. Review the link characteristics for a Prisma Access Hub application.
    1. Click an application in the App Performance section to view the Traffic Characteristics and the links used for the applications traffic.
    2. Click each Link to view the baseline latency, jitter, and packet loss measured for the application across the link.
      Repeat this for all links until you gather sufficient baseline data to modify your Prisma Access Hub path quality profile.
  4. Modify your Prisma Access Hub Path Quality profile based on the latency, jitter, and packet loss baselines you gathered.
  5. Continue configuring SD-WAN as needed.
  6. Monitor Prisma Access Hub Application and Link Performance to further fine-tune your SD-WAN link management profiles.
