Benefits of the unified collection of real-time logs:1. Quickly locate the problem machine in the cluster2, no need to download the entire log file (often relatively large, download time is much)3, the log can be countedA, to find the most frequently occurring anomalies, for tuning processingB, Statistics crawler IPC, Statistical user behavior, do cluster analysis, etc.Based on the above requirements, I adopted the ELK (Elasticsearch + Logstash + kiba
