Hello,

 

I have a question about graphics. We have set a retention on the 7-day charts.

When the graphs are powered with data, we have our 7 days of data.

 

However when we stop the power, we find ourselves with our 7 days of data which shifts in time !

Example :

 

I would have thought that the graphic would have been completely deleted after 7 days !

 

Is this normal working? or I have a problem on my platform?

Thanks You :)

Hello @alexandre,


This is normal as your RRD files have a fixed sized, here X MB for 7 days. RRDTool will start to delete old data to keep the size from reaching the threshold (X MB). So if there’s no data to add to the RRD files, RRDTool will not purge the data.

Keep in mind that old RRD files are also not automatically deleted.
