graphs only show for 2,5 weeks in the graphs output

[ClemensBW]

Hello,

Cacti Version: 0.8.7g
Cacti OS: unix
SNMP Version: NET-SNMP version: 5.4.1
RRDTool Version: RRDTool 1.3.x
Poller: SPINE 0.8.7h

i have some hosts in my cacti, but for a few i think, that the poller dont write the collected data in the rrd files.

I use Interface Traffic with in/out bits (64-bit counters), as the Interface is a 10-GBit.

RRDTool Says:

OK

Have you any idea, what can i check else?

Here is a screenshot, and yes, i collecting it over 2 weeks :o)

Hi !

You could try

Code: Select all

/usr/bin/rrdtool dump /usr/share/cacti/rra/XXX_traffic_in_2221.rrd

to see what the file contains and what is the oldest data, but my guess is that your file was deleted or moved or didn't exist before.

It's the only thing I can think of... hope it helps !

Have a nice day.

Hello,

the oldest output is:

<!-- 2012-10-08 00:00:00 CEST / 1349647200 --> <row><v> 1.5240984975e+07 </v><v> 8.8775755178e+06 /v></row>

But, i'am sure, that this host is more than one month in monitoring :(

[cigamit]

A few things to check. Can you post what your RRAs are, and what RRA are assigned to that data template? Also, can you then do
rrdtool info <rrdfilename>
on the rrd file and post that?

EDIT: Scratch that. One of my many test boxes seems to be doing this also, but only showing 2 days worth. It only happens on a few graphs on a host, but other hosts using that same data template are just fine. Doing a strict comparison of the rrdtool info output between a working and nonworking one, all internal settings are exactly the same. More investigation is necessary. I am wondering if this issue is caused by a bug in RRDTool 1.3.8, is that the same version you have?

[ClemensBW]

Hey, i use Version 1.3.1

Code: Select all

rrdtool -v
RRDtool 1.3.1  Copyright 1997-2008 by Tobias Oetiker <tobi@oetiker.ch>
               Compiled Sep 26 2008 22:29:16

It is a little bit mazy, for graphs older as a three (?) month they work fine, but newer dosn't - i don't know why.

[gandalf]

When using 1 minute polling, you MUST change the RRA definitions to have a longer timespan store in rrd files!

[ClemensBW]

Hello,

we use 5 minute polling with spine.

I compare the 'Data Sources -> RRA' from some cacti installand and the rra-steps are different, i change it now to the correct steps - hope it works :o)

[gandalf]

In case the STEP is different, that won't work.
1. Please know, that change to a data template are not propagated to EXISTING rrd files. New ones will obey to the new definitions, of course.
2. Tobi Oetiker recently published rrdjig, which may help in such a situation; I did not try yet
