Conclusion

If you want to collect data for a baseline, or if you want to trace a problem from way back when, Netdata is the wrong choice, because it only tells you what is happening right now. You can preserve this state in a snapshot and then analyze it when you have the time, but you can't freeze the snapshot in the program for more than five minutes. However, if you need to investigate the state of the system at a moment in time, Netdata lets you study the data from hundreds of angles.
