graph sample rate

Hi,

We just started monitoring a v5000 and a v7000 storage with the same settings, the sample rate is 5 minutes on both. However the displayed graphs are different in resolution, the graphs of v5000 are fine, seems to have sample in every 5 minutes but the graphs of the v7000 seems to have samples in every 20 minutes.

The v7000 graph:


The v5000 graph:


The measure unit is 1 hour.
What can be the problem? Why the graphs of v7000 are not detailed?

Thanks,
Karoly

    Hi,

    it cannot be 20 iminutes, it must be 10 minutes, pls confirm it or send a screenshot with time axis visible.

    It could happen when you initially start with 10 minutes samples, rrdfiless are allocated for 10 minutes sample, switch to 5 mins does not change allocation.
    You would have to remove all data in data/<storage name> after switch to 5 mins.
    I hope I ma clear anougld.

    Checnge from 5 --> 10 minutes is fine, notimg must be removed, just sample rate change

    Hi,

    After recreating the data files, the resolution is 5 minutes again.

    Thanks,
