systemd iperf at startup

[vptech]

Hi folks,
I am new to centos7. I have requirement to run iperf3 (bandwidth testing app) at startup .

I followed the instruction & it works if I wanted to run iperf3 at the startup.
https://arr4.wordpress.com/2016/04/21/i ... a-service/

[Unit]
Description=iperf3 Service
After=network.target
[Service]
Type=simple
User=iperf
ExecStart=/usr/bin/iperf3 -s
Restart=on-abort
[Install]
WantedBy=multi-user.target

But I wanted to pass some parameters like create logfile with --forceflush so when I passed this under ExeStart it does not work & it does not
give me any error .
ExecStart=iperf3 -s -D -J --logfile /var/www/html/iperf/log.json --forceflush

if somebody can point me to right direction .
Sincerely
Viral Patel

Try writing your log files under /var/log/not /var/www - selinux knows about /var/www and restricts what or who can write there to a select list. The /var/log directory is meant for logs.
