Description
Back in 2005 when I have started my career as a server administrator in a startup, I had just 2 servers to manage. That was an easy job with just few websites running on both the servers. However, in next few years I had more than 10 servers running with different application and services. So I had to check the logs of every server and it was like spending more than a half day every day. Slowly the number of servers increased so I have configured few scripts to send me some important log information of each server, but again in just next 1 year I had 50+ servers to manage and it was crazy checking logs and I was worried, as there were all kinds of attacks happening on the servers. It was a huge task to read logs and troubleshooting the issues for each server, all I wanted was to have a centralized log server. I googled and found Logstash, as I was learning more about Logstash I came across with Elasticsearch & Kibana as well and it was a wow moment for me.I have configured the ELK setup and started working on it. The whole experience was amazing, I was able to configure all the service logs and application log to a centralized server and also was able to define the parameters I wanted. The setup helped me to quickly search through the logs and find out the issues. Using the plugins, I have configured alerts as well.
