![]() Instead of default spaces I used quotation mark. Please note also the fact that I used different Field Separator in awk call. If you don’t get responses you are expecting, try to adjust the $6 in the awk call – the User Agent information doesn’t have to be located in the sixth column of your log file. Please note that the above oneliner can be a little bit tricky. It looks like someone was using the software with the User Agent set manually or maybe something like Selenium. grep 23/Jan : Use the grep command to only show hits from today from the Apache access log.: cut -d -f2 cut -d -f1: Use the cut command with the -delimter set to an opening bracket and print out the -field of data that shows up 2nd, then use the cut command again with the -delimter set to a closing bracket and print out the -field of data that shows up 1st which. We can then scroll up through the terminal window and get a quick-and-dirty visual. The cut command there simply throws away all the output except for the first field on each line, which is the IP address. The first thing I checked was the numbe of requests per day: > awk '' | sort | uniq -c | sort -nĩ7 Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/.169 Safari/537.36Ģ834725 Mozilla/5.0 (Windows NT 10.0 Win64 圆4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/.167 Safari/537.36 One quick way to see which IP addresses are most active is to sort by them: cat access.log cut -d -f 1 sort. To make our work easier I combined the access logs from the five past days into one combined log file. ![]() bz2) Visitor IP address is personal information so they should never be publicly disclosed the example below shows mangled IPs (replaced to XXX) to avoid privacy issues. The pieces of bash code listed below helped us to pinpoint the source of the traffic. Logs are rotated daily or weekly depending on system setting so the log folder will possibly contain extra older log files, sometimes zipped (filenames ending in. Parse logs between times Grep IPs causing 403s Find redirects parse to file zGrep and (re)Grep Display top 10 IP addresses Display top 10 URLs how many. In most cases, website owners are noticing some strange activity or unusual traffic peak and we want to check if this has something to do with a particular client or a particular day.įor instance, one of our clients noticed that there is an ususual high number of visits on the whole website (image stock) at the beginning of the current month. Your sample IP address made eight requests. If you’re looking for a count, pipe the results through the word count utility, wc. ![]() From time to time I have a need to analyze Apache access logs real quick. So, now you see each time that a specific IP address accessed this server.
