RRDTool and Graphs all showing NAN after Install

[ahunter]

Hi There,

I am currently have an issue with cacti in that all the graphs are showing a NAN value. I have followed the debug steps and cannot figure out what is causing the issue I am having.

OS: Centos 6.2 x64
Cacti Version: 0.8.8a
Install: RPM

When I run the snmpget or walk it works fine and returns the values. When I run the php poller manually it returns values as below.

11/29/2012 02:51:59 PM - POLLER: Poller[0] CACTI2RRD: /usr/bin/rrdtool update /usr/share/cacti/rra/router_traffic_in_10.rrd --template traffic_out:traffic_in 1354204319:2252943301:1273885056

I have checked the poller_output table and that is clearing out ok with no data left.

The file permissions seem to be ok as the log and rra directories are set to 777 with the cactiuser:root.

I have deleted the rrd's and they are being created ok.

When I run the rrdtool manually from the command line (rrdtool fetch /usr/share/cacti/rra/router_traffic_in_10.rrd AVERAGE) I get a list of NAN values as below.

1354199400: -nan -nan
1354199700: -nan -nan
1354200000: -nan -nan
1354200300: -nan -nan
1354200600: -nan -nan
1354200900: -nan -nan
1354201200: -nan -nan
1354201500: -nan -nan
1354201800: -nan -nan
1354202100: -nan -nan
1354202400: -nan -nan
1354202700: -nan -nan
1354203000: -nan -nan
1354203300: -nan -nan
1354203600: -nan -nan
1354203900: -nan -nan

When I check the rrdtool info I get the below output.

Can anyone help as I am not sure what to check next or how to resolve this issue.

Many thanks

Please select "System Utilities -> Rebuild Poller Cache" and wait 10 min. Does that help?

Thanks for the reply. Unfortunately this did not work.

I managed to get this resolved by using the tar.gz and uninstalling the RPM. This could have been down to permissions I in the directories.
