For this tutorial, well be using data supplied by Metricbeat, a light shipper that can be installed on your server to periodically collect metrics from the OS and various services running on the server. Timelion uses a simple expression language that allows retrieving time series data, making complex calculations and chaining additional visualizations. My First approach: I'm sending log data and system data using fluentd and metricbeat respectively to my Kibana server. These extensions provide features which }, The first step to create a standard Kibana visualization like a line chart or bar chart is to select a metric that defines a value axis (usually a Y-axis). This sends a request to elasticsearch with the min and max datetime you've set in the time picker, which elasticsearch responds to with a list of indices that contain data for that time frame. To do this you will need to know your endpoint address and your API Key. Thanks Rashmi. The metrics defined for the Y-axis is the average for the field system.process.cpu.total.pct, which can be higher than 100 percent if your computer has a multi-core processor. but if I run both of them together.
