A log management system is essential for the networks administrator. With a log management tool, we can collect, store, analyze, archive, and finally dispose of the log information. In this paper, we propose the architecture model of a log management system using ELK Stack with Ceph to provide a safe network, good Wi-Fi signal strength, and adequate backup data mechanism. In this case, we use our campus data of Wi-Fi log and NetFlow log. First, we collect and store data of our Wi-Fi log using Filebeats tool, and then, we use Elasticsearch, Logstash, and Kibana Stack to visualize the Wi-Fi log data. Second, we collect and store our NetFlow log using NFDUMP, and then, we also use ELK Stack to visualize the NetFlow log data. Third, we integrate the Wi-Fi log and NetFlow log data in one architecture using a distributed storage Ceph file system (CephFS). Moreover, we also compare the performance of RADOS Gateway and CephFS for better storage mechanism.
