Technical Tip: How to obtain old data of an SD-WAN Performance-SLA

[stroia]

Description	This article describes how to see old measures of an SD-WAN Performance-SLA.
Scope	FortiManager.
Solution	In Fortinet SD-WAN, Performance SLAs are important to monitor SD-WAN members' status to adapt consequentially the FortiGate behavior. For example with a configured Performance SLA like this (FortiManager Performance SLA view): Some users go to see the Performance SLA measures from the FortiGate in SD-WAN -> Performance SLA TAB: From there is possible to see only the trend in a short period. To see the graphs with the Performance SLA trend on a longer time range is necessary to enable the sdwan-monitor-history feature in the FortiManager, as explained here: Enabling SD-WAN monitoring history. In FortiManager CLI: config system admin setting     set sdwan-monitor-history enable Important note: Pay attention to the impact of this feature, as explained in the document mentioned before. There are 2 options to see the graphs of measures: First option: Going to: SD-WAN Manager -> Network -> Monitor and scrolling down, the last graph group is of active Performance SLAs: It is possible to customize the graph interval (without the sdwan-monitor-history feature is possible to see only the last 10 minutes). Second Option: Add the SD-WAN widget in ad hoc TAB, under the Dashboard TABs group of a single FortiGate managed. Path of the Dashboard TAB group: Device Manager -> Device Group Select the Device. How to add the widget: Scrolling down on the new TAB: Data shown in the graphs are very useful to verify if a: 'random traffic slowness' problem, with it not ongoing during technicians' troubleshooting, is caused by SD-WAN members' bad performances.
