I need to count how many times different IP's were in the file.

I'm using this to open file because i don't have grep rights to do it only with grep

My Rights

User lotarc may run the following commands on herbert:
    (root) /bin/su - censored
    (root) /bin/su - censored
    (root) /bin/cat /var/log/nginx/access.log, /bin/cat /var/log/nginx/access.log.1, /bin/zcat /var/log/nginx/access.log.[0-9]*.gz, /bin/cat /var/log/nginx/error.log, /bin/cat /var/log/nginx/error.log.1, /bin/zcat
        /var/log/nginx/error.log.[0-9]*.gz

sudo cat /var/log/nginx/access.log.1 | grep -E '1ip|2ip|3ip'

My question is how to count this ip's and get the output. I need to count from multiple files like access.log.2.gz

Content of file

some ip - - [30/Sep/2019:07:26:03 +0300] "POST /clientapp/request/signUp HTTP/1.1" 200 0 "-" "python-requests/2.22.0" "-"

  • @msp9011 Of course. I need to count specific ip`s Check my edit to see content – Semyon Kolesnikov Sep 30 '19 at 12:49
  • And i guess i need to count each ip's, how many times it does this request from the question – Semyon Kolesnikov Sep 30 '19 at 12:53

Try this,

cat access_log | awk '{a[$1]++} END {for(i in a) print a[i],i}' | sort -n | tail -n1

For specific IPs:

cat access_log | awk '$1 == "192.168.1.37" || $1 == "192.168.1.110" {a[$1]++} END {for(i in a) print a[i],i}'

  • It's working well. Now i'm going to try to sort it, because there's many ip's i want to find only with the highest value of requests – Semyon Kolesnikov Sep 30 '19 at 13:14
  • If you are trying to find the highest value, I think a combination of sort and uniq can help you, if you can use those. – number9 Sep 30 '19 at 13:27
  • @msp9011 I found a problem. Your first code is adding 0 after ip like 34228 91.219.253.1100 but it's should be 34228 91.219.253.110 – Semyon Kolesnikov Sep 30 '19 at 13:36
  • @number9 I tried to use sort and uniq, but it doesn't help me. – Semyon Kolesnikov Sep 30 '19 at 13:37
  • @SemyonKolesnikov it shouldn't be... can u share few lines with those IP? – Siva Sep 30 '19 at 13:41

I might be off my rocker, but this looks straightforward if you just want the count.

 awk '{print $1}' access.log |uniq |wc -l

This will output the count from the one file. If you want all of them you could zgrep all of them and use the dreaded IP address regex:

zgrep '\(25[0-5]\|2[0-4][0-9]\|[01][0-9][0-9]\|[0-9][0-9]\)\.\(25[0-5]\|2[0-4][0-9]\|[01][0-9][0-9]\|[0-9][0-9]\)\.\(25[0-5]\|2[0-4][0-9]\|[01][0-9][0-9]\|[0-9][0-9]\)\.\(25[0-5]\|2[0-4][0-9]\|[01][0-9][0-9]\|[0-9][0-9]\)' access.log.*.gz | awk '{print $1}' | uniq |wc -l

Of course, I bet there is a much simpler way that some clever person can give you, but it is a bit early in the morning for me, I am just throwing this solution out there. Tested on my webserver running nginx, it works for my 50+ logfiles.

As per the OP, if you do not have zgrep, you can just run the logfiles through gzip first...

OP noted in a different message that this worked for him. This is also taken from msp9011 solution, so giving credit there.

cat access.log | awk '{a[$1]++} END {for(i in a) print a[i],i}' |sort -nr

OP would like the solution to print lines with greater than 100 requests. It can be done in one awk statement, I think, but I will do it the brute force way:

  cat access.log | awk '{a[$1]++} END {for(i in a) print a[i],i}' |awk '$1>100' | sort -nr

  • You beat me to the awk answer by about 45 seconds. The second answer here will not work if IPv6 addresses are in the log. – doneal24 Sep 30 '19 at 12:59
  • I can't use zgrep and grep without cat. My rights is in edit – Semyon Kolesnikov Sep 30 '19 at 13:01
  • Ohhh, good one. I always forget IPv6. I wish it was simpler – number9 Sep 30 '19 at 13:01
  • @number9 I want to exclude ip's where less than 100 requests. I tried a couple variants but it doesn't work, can you help pls? – Semyon Kolesnikov Sep 30 '19 at 13:55
  • I updated my solution – number9 Sep 30 '19 at 14:30
