cacti RRA graphics can be displayed about 5 months time data

[Qinxocy]

Such as the title, year graphics inside the RRA graphics can only save the displayed about 5 months time data, data source inside the circular file I write is a 3840 line( default is 799).
please help me，this issue for several months before it has occurred for a long time ( 2008 just installed when no this problem ), how should I check？
If you can, you can add my msn:124483360@qq.com

What do you mean "default 799,Last Thursday instead of 3840, today found or lose data"? Did you just change this value?

This is how rrdtool functions. Read:

I have not changed inside the script numerical, is cacti by default, why other people do not appear on this problem, and I suddenly appears in this issue?

Please post output of "rrdtool info" run against the rrd file in question. Then, let's see

I checked the RRD file: rra[4].pdp_per_row=799

In my webpage changes above 3840 did not take effect.

Now how to do, how to make the RRA file inside rows into 3840.

Don't affect my current situation, how to modify the RRA file？

is there nobody to know？

You can't _change_ an existing rrd file that way. You will have to modify the RRA/Data Template and then drop the rrd file. A new one, using the latest definitions, will be created on next polling interval
R.

I found online with resize.pl ( http://forums.cacti.net/viewtopic.php? T=11425 ) this script to modify the RRA file, is excuse me this modification, can use this to achieve my aim now?

If you mean all to do, the previous data will be lost, but I must retain the previous data.

[gandalf]

RRDTool files can't be changed with respect to several parameters. So, in case you've chosen a 1 min polling and did NOT change RRAs accordingly, you're at a loss.
You may reserach rrdjig and/or RRD::tweak to work around some of those restrictions.
Or, when keeping polling interval and only "adding" more rra slots, a resize indeed may help
