Several commands for viewing processes and logs

Several commands for viewing processes and logs-Linux Enterprise Application-Linux server application information. The following is a detailed description. When I configured nagios today, I found 1272 processes, which scared me to death. Let's take a look at it on the server.

# Ps-ef | wc-l
1271

There are so many.

Check again
# Ps-ef | grep httpd | awk '{print $ NF}' | sort-nr | uniq-c
1201 start --- this is abnormal

It's really scary. Let's take a look at it. The apache on this machine is useless. Shut it down directly.

The process returns to normal. Can I modify the apache configuration file to solve this problem?

Because squid transparent proxy is used in the company's Intranet, the sarg used for log processing is viewed in a browser, but not in the command line.

So I went on to ask.

The most stupid method I use
Cat/home/squid2/var/logs/access. log | grep 'IP'> **. txt
Tail **. txt

You can find the most recent access record of this IP address.

Question 1: How can I use a single command to implement it?
Question 2: How can I display a log in a format that does not display time?

Hey. IORI command.

# Cat/home/squid2/var/logs/access. log | awk '{$1 = strftime ("% c", $1)} {print $0}' | grep '10. 0.0.252 '| tail-n1
