Log parser

TL;DR

npm i && sudo node createTestLogFile.js 6 && npm start
GET localhost:12345/search?fileName=cribl_test_log_6&numLines=20&searchTerm=12345

Setup

To generate a large log file under /var/log called cribl_test_log_<num>:

sudo node createTestLogFile.js <num> where num is log10 of the number of lines to write to the test file.

For example, to create a file with 1e6 lines, run sudo node createTestLogFile.js 6. sudo is needed to write the file to /var/log

2. To search the generated file:

Usage

1. npm i && npm start

2. Send a GET request to localhost:12345/search?fileName=<filename>&numLines=<number>&searchTerm=<string>, where:

   • filename is the name of the log file located under /var/log
   • searchTerm is the term to filter the lines by. Defaults to no filtering
   • numLines is the number of matches you'd like to receive. Defaults to 20

To search the file generated in the setup step: GET localhost:12345/search?fileName=cribl_test_log_6&numLines=20&searchTerm=12345
