Charts use fixed intervals based on the selected time range (for 1-day it’s 10 minutes).
Changing the agent interval doesn’t change this, so with a 15-minute interval for data collection, you may end up with a chart with missing bars, the only way to find out is to try. If that happens and you don't want to have missing bars, you could either lower the interval to 10 minutes, or monkeypatch the code to change this line: https://github.com/openwisp/openwisp-monitoring/blob/a01667ba0172dd9c96d95769faa3f95b782ec869/openwisp_monitoring/monitoring/base/models.py#L528 I recently shared on Github Discussions a solution to monkey-patch the DeviceAdmin class to modify the columns listed in the device list: https://github.com/openwisp/ansible-openwisp2/discussions/547#discussioncomment-14489173 You can adapt that solution and change the ready() method to do something like: AbstractChart.GROUP_MAP["1d"] = "15m" You may want to ask yourself if it makes sense to have a monitoring system that gets updates every 15 minutes, which in many deployments could be considered a long time. However, it may work for you, so if you think that's the case, you can adapt the system. I think we cannot ship a default setup that suits everyone, but we should definitely make it possible to change the existing behavior whenever possible. I hope this helps.
