Steps to add performance policy SLAs that provide latency, packet loss, and jitter
thresholds.
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:
Go to
Manage
Policies
Performance
Performance SLAs
and select
Add New SLA
.
In the
Add New Performance SLA
screen, enter a
Name
for the SLA with the option of including a
description and tags.
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
