Add Performance Policy SLA

Where Can I Use This?	What Do I Need?
Prisma SD-WAN	Active Prisma SD-WAN license. Physical and virtual ION devices running software version 6.3.1 and higher.

The Performance SLAs tab contains Prisma SD-WAN performance SLAs. It provides the Application, Link Quality Metrics, System Health, Circuit Utilization, Flow and, Probe SLA threshold values for the performance policy rule.

Use the Actions icons to Edit a performance SLA, view the audit logs for any system configuration changes, or remove a performance SLA.

To add a performance SLA:

1. Go to ManagePoliciesPerformancePerformance SLAs and select Add New SLA.
2. In the Add New Performance SLA screen, enter a Name for the SLA with the option of including a description and tags.
3. Select the desired Metrics from the drop-down.

   • If you check the option Link Quality Metrics,
     • Enter the Latency value (between 1-500ms).
     • Continue to click the + sign or select from the drop-down to enter the Jitter value (between 1-100ms), the MOS value (between 1-5), and the Packet Loss value (between 1-20%).
     On a per-branch circuit basis, the Jitter, Latency and Packet Loss values will utilize the best (lowest) measured value between the Branch and all Data Centers.
   • If you check the option Application Metrics,
     • Provide the Init Failure Rate (between 1-100%).
     • Continue to click the + sign or select from the drop-down to enter the RTT value (between 1-500ms) and the UDP TRT value (between 1-500ms).
       Init Failure rate is the percentage of TCP 3-way handshake failures and RTT is the TCP Round Trip Time from a client to the server and back to the client.
       UDP Response Time (UDP-TRT) is the amount of time it takes for the server to respond to the UDP transaction request from the time the request is received. Currently, UDP-TRT provides information on UDP DNS traffic only.
   • If you check the Probe option,
     • Select the Probe config from the drop-down. Depending on the probe config selected (DNS/HTTP/ICMP), enter the value for the following probe metrics:
       • DNS Transaction Time (between 1-500ms), and the DNS Transaction Failure Rate (between 1-100%).
       • HTTP Transaction Time (between 1-500ms), and Init Failure Rate (between 1-100%).
       • Latency value (between 1-500ms), and continue to click the + sign or select from the drop-down to enter the Jitter value (between 1-100ms) and the Packet Loss value (between 1-20%).
   • If you check the option System Health Metrics,
     • Enter the CPU Utilization value (between 1-100%).
     • Continue to click the + sign or select from the drop-down to enter the Memory Utilization value (between 1-100%) and the Disk Utilization value (between 1-100%).
   • If you check the option Circuit Utilization, enter the Circuit Utilization value (between 1-100%).

   • If you check the option Flow Metrics, enter the Concurrent Flow Utilization value (between 1-100%).
