To logging PQS, you can log using NGINX as a proxy that records the HTTP Request Body and the timing.
On your Centos/RHEL machine, switch to root privileges
Install nginx packages, and you can setup a proxy
yum install nginx.x86_64 -y
Create the nginx configuration so you have a log_format that outputs the body ($request_body) and time ($request_time)
Create the default server configuration, and set the proxy_pass to point to your PQS/phoenix query server
nginx -s reload
Tail the log file to see the data called.
[root@data-com-4 pbastide]# tail -f /var/log/nginx/request-body.log
