opnsense interface statistics reset to zero after rebooting

[cybersans]

dear all,
1st of all i am sorry this question already been asked and been answered, because i didn't find any similar using forum search and google.

the question is: why interface statistics always reset to zero(0) after rebooting? the traffic graphs also start a new graphs.
are the logs not been saved in a logfile?

the interfaces/overview adapter's interface in/out packets counters also reset to zero.

regards

All these are runtime stats. Only Netflow/Insight stores historic data.
