I'm using the following command to get the highest number of requests per second in a log file and it works well. grep 2017-02-22 LogFile.log | cut -c1-20 | uniq -c | sort -n | tail -n1Now I would like to also get the smallest requests per second and the amount of time the highest number stayed for. For example: let's say the results from the command was 2000 which is the highest requests per second inside the log file, I want to find out how long the 2000 requests lasted for? in another word: if the peak of 2000 happened, I'd like to find out how long it took before this went down.Here's a portion of the log file:#Start-Date: 2017-02-16 19:49:06#Date: 2016-10-11 15:16:48#Fields: date time time-taken c-ip cs-username cs-auth-group x-exception-id sc-filter-result cs-categories cs(Referer) sc-status s-action cs-method rs(Content-Type) cs-uri-scheme cs-host cs-uri-port cs-uri-path cs-uri-query cs-uri-extension cs(User-Agent) s-ip sc-bytes cs-bytes x-virus-id x-bluecoat-application-name x-bluecoat-application-operation#Remark: 1412140034 lofnetsg1 192.168.13.14 main2017-02-16 19:49:06 116154 10.5.13.149 - - - OBSERVED Non-Viewable/Infrastructure -  200 TCP_TUNNELED CONNECT - tcp u-amvx4npjuy.wc.yahoodns.net 443 / - - Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 6603 1036 - none none2017-02-16 19:49:06 1 10.2.29.41 - - - OBSERVED Technology/Internet -  304 TCP_HIT GET application/pkix-crl http www.microsoft.com 80 /pki/CRL/products/Microsoft%20Windows%20Hardware%20Compatibility%20PCA(1).crl - crl Microsoft-CryptoAPI/6.1 192.168.13.14 568 338 - none none2017-02-16 19:49:06 18 10.1.15.166 - - - OBSERVED Content Servers http://www.foxnews.com/  304 TCP_CLIENT_REFRESH GET text/javascript;charset=UTF-8 http widget-cdn.rpxnow.com 80 /translations/share/en - - Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 487 417 - none none2017-02-16 19:49:06 6677 172.16.121.69 - - - OBSERVED Social Networking;Content Servers -  200 TCP_TUNNELED CONNECT - tcp pbs.twimg.com 443 / - - Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 100203 1241 - Twitter none2017-02-16 19:49:06 1664 10.14.16.67 - - - OBSERVED Informational;Health -  200 TCP_TUNNELED CONNECT - tcp www.drugs.com 443 / - - Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko 192.168.13.14 6313 2281 - none none2017-02-16 19:49:06 1095 172.16.121.69 - - - OBSERVED Web Ads/Analytics -  200 TCP_TUNNELED CONNECT - tcp as-sec.casalemedia.com 443 / -- Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 1058 2818 -none none2017-02-16 19:49:06 24282 172.16.121.69 - - - OBSERVED Web Ads/Analytics -  200 TCP_TUNNELED CONNECT - tcp dt.adsafeprotected.com 443 / - - Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 3687 3007 - none none2017-02-16 19:49:06 1 10.2.29.41 - - - OBSERVED Non-Viewable/Infrastructure -  304 TCP_HIT GET application/pkix-crl http crl.microsoft.com 80 /pki/crl/products/MicrosoftTimeStampPCA.crl - crl Microsoft-CryptoAPI/6.1 192.168.13.14 500 304 - none none2017-02-16 19:49:06 48 10.2.50.46 - - - OBSERVED Web Ads/Analytics -  200 TCP_TUNNELED CONNECT - tcp x.bidswitch.net 443 / - - Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 39 219 - none none2017-02-16 19:49:06 26855 172.16.121.69 - - - OBSERVED Web Ads/Analytics -  200 TCP_TUNNELED CONNECT - tcp ping.chartbeat.net 443 / - - Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 699 2727 - none none2017-02-16 19:49:06 22 10.2.10.172 - - - OBSERVED Web Ads/Analytics http://player.radio.com/listen/station/985-the-sports-hub  200 TCP_NC_MISS GET application/javascript;%20charset=utf-8 http ib.adnxs.com 80 /ttj ?id=10203641&size=300x250&pagetype=ros&promo_sizes=&cb=1487274546795 - Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 192.168.13.14 11458 3251 -none none2017-02-16 19:49:06 965 10.32.14.38 - - - OBSERVED Technology/Internet -  200 TCP_TUNNELED CONNECT - tcp clients4.google.com 443 / - - Chrome WIN 56.0.2924.87 (0e9a9a6f3676ae439b78cd9b3f62b4193c3ac7d5-refs/branch-heads/2924@{#895}) channel(stable) 192.168.13.14 1455 3073 -none none2017-02-16 19:49:06 939 10.7.18.97 - - - OBSERVED Health http://cmri.in/cmri-doctors/  200 TCP_NC_MISS GET text/html;%20charset=UTF-8 http cmri.in 80 /doctor/dr-mahesh-chowdhury/ - - Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:51.0) Gecko/20100101 Firefox/51.0 192.168.13.14 7501 573 - none none
