Tracking process via ps command

Hello folks,

I am tracking a process httpd only. But when i am grepping it, it is returning me multiple process of httpd, second it is showing another process of monitorix-httpd. Below commands i have tried.

Code:
Current output

# ps ax |grep http
  929 ?        Ss     0:00 monitorix-httpd listening on 8080
 9551 ?        Ss     0:00 /usr/sbin/httpd -k start
 9552 ?        S      0:00 /usr/sbin/httpd -k start
 9554 ?        S      0:00 /usr/sbin/httpd -k start
 9555 ?        S      0:00 /usr/sbin/httpd -k start
 9556 ?        S      0:00 /usr/sbin/httpd -k start
 9557 ?        S      0:00 /usr/sbin/httpd -k start
 9558 ?        S      0:00 /usr/sbin/httpd -k start
 9559 ?        S      0:00 /usr/sbin/httpd -k start
 9560 ?        S      0:00 /usr/sbin/httpd -k start
 9561 ?        S      0:00 /usr/sbin/httpd -k start



Expected output: one process that confirms that httpd is running, not all httpd child process and neither monitorx process.

Code:
expected output


httpd

NAME
micro-httpd - really small HTTP server SYNOPSIS
micro-httpd DIRECTORY OPTIONS
None. DESCRIPTION
micro-httpd is a very small HTTP server all in 150 lines of code. It runs from inetd, which means its performance is poor. But for low- traffic sites, it is quite adequate. It implements all the basic features of an HTTP server, including: * Security against ".." filename snooping. * The common MIME types. * Trailing-slash redirection. * index.html * Directory listings. To install it, add a line like this to /etc/inetd.conf: micro-http stream tcp nowait nobody /usr/sbin/micro-httpd micro-httpd dir Make sure the path to the executable is correct, and change "dir" to be the directory you want to serve. You could add line like this to /etc/services: micro-http port/tcp #Micro HTTP server Change "port" to the port number you want to use: 80, 8000, whatever. Restart inetd by sending it a "HUP" signal. On some systems, inetd has a maximum spawn rate - if you try to run inetd services faster than a certain number of times per minute, it assumed there is either a bug of an attack going on and it shuts down for a few minutes. If you run into this problem - look for syslog messages about too-rapid looping - you will need to find out how to increase the limit. Unfortunately this varies from OS to OS. On FreeBSD, you add a "-R 10000" flag to inetd's initial command line. On some Linux systems, you can set the limit on a per-service basis in inetd.conf, by changing "nowait" to "nowait.10000". Note that you can use micro-httpd to serve HTTPS, if you like, by running it from stunnel. First fetch and install stunnel - FreeBSD users can just go to /usr/ports/security/stunnel and do a "make cert ; make install". Then as root run: stunnel -p /usr/local/certs/stunnel.pem -d 443 -l /usr/sbin/micro-httpd -- micro-httpd dir Make sure the paths to the certificate and executable are correct, and again don not forget to change "dir" to the directory you want to serve.
