LogIQ

LogIQ is a simple monitoring front end for Elastic Logstash. It uses Monitoring API.

Tested on Logstash versions 6.x-7.x

Usage

Open the html page and add your Logstash hosts with port number. You need internet connection as the page uses external libraries like bootstrap, jquery and echarts.

Logstash Configuration

You need to enable remote connections on Logstash, just add the line in Logstash config file (default /path/to/logstash/config/logstash.yml):

http.host: "0.0.0.0"

Logstash may not allow CORS calls, you can use proxy to fix this. Install Nginx and add this section in /etc/nginx/nginx.conf:

server {
        listen       9601;
        location / {
          if ($request_method = 'GET') {
          add_header 'Access-Control-Allow-Origin' '*';
          add_header 'Access-Control-Allow-Methods' 'GET';
          add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
          add_header 'Access-Control-Expose-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
          }
          proxy_pass http://logstash:9600;
        }
    }

Don't forget to set your logstash hostname and exposed port. After Nginx restart it will proxy requests from port 9601 to 9600 with right headeres.
