We are collecting some values of our servers, e.g. read and write to disk, using collectd + elk stack. The collecting part was no problem at all. Discovery is also fine, but now I want visualize the data.
The problem is in the aggregation part. Because I do not want to aggregate read/write of disk. I just want their value over a period, e.g. last 24 hours with hourly intervals. I have tried to find the result I need using Date Histogram on the X-axis but then what should I do on the Y-axis? Is this possible with Kibana 4; and if so, how should I approach it?
Thanks for the help!
