[SOLVED] Graph missing data

Post by maunded »

Hi,

I have a graph on an external ADSL2+ connection that is limited to around 10Mb. The graph i have seems to fail when its data goes over 5Mb.

Image

The inbound data in the circled area was about 6Mb/sec.

Graph Debug:

Code: Select all

/usr/local/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-60 \
--title="fw1-juniper stats - Traffic - adsl1/0" \

--width=500 \

--vertical-label="bits per second" \

Data source debug:

Code: Select all

/usr/local/bin/rrdtool create \
/usr/local/apache2/htdocs/cacti/rra/fw1-screenos_traffic_in_321.rrd \
--step 60  \
DS:traffic_in:COUNTER:120:0:100000000000 \
DS:traffic_out:COUNTER:120:0:100000000000 \

RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:500 \

RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \
I have full logging enabled and there are no errors in the logfile.

I have other graphs based on the same template that are showing over 800Mb/sec (switches), so I cant understand why my graph isnt working.

Thnks
D.

If you are using spine 0.8.7e, turn logging to medium. Spine hides "timeouts" now in the latest version unless under medium. You should increase your snmp timeout.

I dont see any errors, the output looks to be correct

Code: Select all

03/26/2010 03:03:07 PM - CMDPHP: Poller[0] Host[43] DS[320] SNMP: v1: fw1-hendra.smcbne.com, dsname: traffic_out, oid: .1.3.6.1.2.1.2.2.1.16.2, output: 317042446  
03/26/2010 03:03:07 PM - CMDPHP: Poller[0] Host[43] DS[320] SNMP: v1: fw1-hendra.smcbne.com, dsname: traffic_in, oid: .1.3.6.1.2.1.2.2.1.10.2, output: 1136151325
EDIT: I should add that Im not using spine, only cmd.php

Well, that's your first mistake. It's an snmp timeout for sure then.

What is the rrd files MAX for that data source? I suggest setting this to "U" (use rrdtool tune) to make sure that data is not capped for the time being.

I updated to spine and tested with the same result, I then set the rrd max to 'U' for the data source and still have the same result.

Image

The first gap is where I tested with spine running instead of cmd.php, the second where i set the data source to max=U.
Heres my graph and data source debug:

I have logging set to medium and there are no warnings or errors in the log file.

Please do not only change the data source but the rrd file itself (cacti won't do that for you). Use rrdtool tune to change the MAX

Please see "man rrdtune", e.g.

Code: Select all

rrdtool tune <file> --maximum <ds-name>:<new max value>

Scripts to walk your rra directory have already been posted. Change the Data Template to make sure all new rrd files are created correctly.

I followed the debugging and can still can not figure out why i have gaps in my graphs.

When i did:
rrdtool fetch localhost_proc_7.rrd AVERAGE

I found lots of "nan" I know this is not right.

When i did :
rrdtool info localhost_proc_7.rrd

What is my problem?

I see this:
