NAME         top

       pmdanginx - nginx performance metrics domain agent (PMDA)

DESCRIPTION         top

       pmdanginx is a Performance Metrics Domain Agent (PMDA) which
       exports performance metrics from nginx(8) - an HTTP and reverse
       proxy server, a mail proxy server, and a generic TCP proxy

INSTALLATION         top

       This PMDA requires that the nginx stub_status module is active
       and available at http://localhost/nginx_status .

       In order to enable this module, the "server" section of the
       nginx.conf configuration file should contain the following.

            location /nginx_status {
                stub_status on;
                access_log off;
                allow ::1;
                deny all;

       Instrumentation availability can be verified using these commands
       (compile-time then run-time checks):

           # nginx -V 2>&1 | grep -o with-http_stub_status_module
           # curl http://localhost/nginx_status

       Install the nginx PMDA by using the Install script as root:

           # cd $PCP_PMDAS_DIR/nginx
           # ./Install

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/nginx
           # ./Remove

       pmdanginx is launched by pmcd(1) and should never be executed
       directly. The Install and Remove scripts notify pmcd(1) when the
       agent is installed or removed.

       Environment variables with the prefix PCP_ are used to
       parameterize the file and directory names used by PCP. On each
       installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF variable may be used to
       specify an alternative configuration file, as described in
