Kibana

Visualizing data using Logstash and Elasticsearch.

Short and Sweet

Let's see how much we can do on one line.

Software engineering, testing methods, build workflows and deployment mechanisms.

Threat mitigation, systems monitoring, traffic visualization and troubleshooting.

Systems design, server and container management and scaling .

Automating Logstash Configurations With Consul-Template

Consul and Consul-Template are two powerful tools for updating server files and executing a command after the file has been updated. This makes it a great and lightweight tool for managing configuration files for applications that need to reload or restart after
