Hello, can someone guide me on this?

I don't know what is the best approach, (awk script, shell script)

I am using RedHat Linux version 6.5. There is a third party application deployed on that server. This app by default generates 5 log files and each file is 20MB. These log rollover automatically so at any given time there always be 5 log file like below

appname.log
appname.log.1
appname.log.2
appname.log.3
appname.log.4

When the app runs, it creates the following entries in the log file. for simplicity, i have removed the other information.

Requirement is whenever this string RESTful/BR4/Dispatchers/Drop Down Dispatch Process.process/Log appears in the log file, count it. So at the end of the day, we wanted to know on Oct 20, 2018, how many times that entry appeared in the log file. Basically, everyday, we need to collect statics about this app. The script should run automatically and spit out the stats in a file like this

appname date count

Code:

BW.AMI_Services-Dropdown-AMI_Services-Dropdown-ProcessArchive Oct 20, 2018 3

-----log files entries------

Code:

2017 Oct 20 13:44:03:359 GMT -0600 BW.AMI_Services-Dropdown-AMI_Services-Dropdown-ProcessArchive User [BW-User] - Job-20540 [Services - RESTful/BR4/Dispatchers/Drop Down Dispatch Process.process/Log]:
