Join/Merge Multiple Log Files For Big Data Analysis
Normally log automatically should grow as big possible. But we use logrotate which does the opposite action as running cat and other tools on SSH over big files consumes memory, time and often difficult to do what we want. Also, old files are compressed. Here are the ways to join/merge multiple log files for big data analysis, store them to openstack based cloud storage and delete old … [Read more...]
