 Posted: Mon Oct 13, 2008 9:20 am Post subject: Network traffic .rrd files not created and NaN |
 |
|
Hi. I'm running cacti-0.8.7b-r2 with rrdtool-1.2.27 and net-snmp-5.4.1.1 on a Gentoo Linux system.
My problem: .rrd files for network traffic are not created and therefore I have no graphs.
When running rrdtool graph on debug mode for device tun0 I get the following error:
| Code: |
RRDTool Command:
/usr/bin/rrdtool graph - \

RRDTool Says:
ERROR: opening '/usr/share/webapps/cacti/0.8.7b-r2/htdocs/rra/mybox_traffic_in_47.rrd': No such file or directory
|
Read on the docs that at the next poller interval the graphs would be created but this error remains since the first moment.
Then, I got to the Data Sources tab and checked the rrdtool create command:
| Code: |
Data Source Debug
/usr/bin/rrdtool create \
/usr/share/webapps/cacti/0.8.7b-r2/htdocs/rra/mybox_traffic_in_47.rrd \
--step 300 \
DS:traffic_in:COUNTER:600:0:U \
DS:traffic_out:COUNTER:600:0:U \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \
|
Had run this on the cli to manually create the .rrd file and waited some polling cycles.
Graphs now appear on cacti but with NaN values. Now running rrdtool graph in debug mode looks fine:

Now some extra info.
Cacti collects data locally:

Poller and cron interval are set to 5min each.

Folder log/ and rra/ belongs to user apache, which is working ok to other graphs.
Could get some help here, because don't know where to look now. Thanks. |

Please check the file ownership of those files you've created manually. They may belong to you instead of cactiuser.
Please follow 2nd link of my sig, even if you already did some of those tests

Hi gandalf. Thanks for replying.
The files I've created are set to apache, so nothing wrong here. And I will re-check the NaN debug guide.
But... do you have any idea why the .rrd files are not created automatically? |

Well, my graphs are getting values now  ... but I'm not sure what did the trick. Anyway, new graphs need to be created manually using the rrdtool create command displayed at Data Sources. I would like to know why this is happening but till then I will do this workaround. I will mark this post [SOLVED] after I get the solution to this issue. |

| I had this same issue. Let's wait and hope that it fixes itself. Or have someone found the issue of this case? |
