Chapter 17 Traffic Shaping for FortiOS 5.0 : Troubleshooting traffic shaping : Shaper diagnose commands : Packet loss with statistics on shapers
  
Packet loss with statistics on shapers
For each shaper there are counters that allow to verify if packets have been discarded. To view this information, in the CLI, enter the command diagnose firewall shaper. The results will look similar to the following output:
diagnose firewall shaper traffic-shaper list
name limit_GB_25_MB_50_LQ
maximum-bandwidth 50 Kb/sec
guaranteed-bandwidth 25 Kb/sec
current-bandwidth 51 Kb/sec
priority 3
dropped 1291985
The diagnose command output is different if the shapers are configured either per-policy or shared between policies.
For per-IP the output would be:
diagnose firewall shaper per-ip-shaper list
 
name accounting_group
maximum-bandwidth 200000 Kb/sec
maximum-concurrent-session 55
packet dropped 3264220
