Hello, whad does this graps mean ? Processor has 100 % load ?
Image

Also - on graph "processor load" i set time interval "Last hour", but when i press on "Zooming and debugging utilities" for this graph, i see data not for last hour - i see data for 1 day and 1 hour ago. For example - screenshot below - is time 09.04.2018, but time on screenshot, below the graph - 08.04.2018 - Why ?

The reason that says 100% I/O load is because you are not receiving data for the other cpu metrics.

Due to the graph being a stack graph if the other values are 0% then I/O wait will be 100%. Check to make sure those OIDs are valid on the device you are monitoring and the device is up.

I'm amazed how a system can be 99% idle and have an iO Wait of 100%... I suspect that there may be some decimal place offsets going wrong somewhere...
