I tried adding this map but it did not remove the orginal values from the graph
and I could not find where they are stored. I do not think that the problem is
related to 100 vs 1024 as some manual calculations do not match again the value
that I am seeing on the graph.
It has been a while since I have played with RRD and I would of expected a
standard check command from Nagios to graph correctly. It just seems to be the
RRD interpolation of the performance data as the check command is outputting
the correct performance data values.

Subject: Re: [Nagios-users] Nagios Graph not displaying correct values
Some of the default Nagiosgraph map entries are strange and behave not as
expected.
I basically replaced all the existing entries by own ones.
If you like you can use the following one:
# Service Type: check_disk
# Nagiosgraph regex by Claudio Kuenzler
# Check: /usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /
# Output: DISK OK - free space: / 235120 MB (66% inode=95%):
# Perfdata: /=119211MB;298635;335964;0;373294
/perfdata:(.*)=(\d+)MB;(\d+);(\d+);(\d+);(\d+).*/
#/perfdata:(\W)=(\d+)MB;(\d+);(\d+);(\d+);(\d+).*/ # only / partition
and push @s, [diskusage,
['used', GAUGE, $2*1000**2 ],
['total', GAUGE, $6*1000**2 ] ];
Note that this is a very basic graph which shows the total and current
partition usage. Feel free to modify it :-)

I have a weird situation where the Nagios Graph values are not the actual
values for a filesystem
Eg I have a filesystem and if I run a df I get
$ df -h .
Filesystem Size Used Avail Use% Mounted on
filer01:/vol/data1 443G 400G 44G 91% /mnt/filer01_data1
If I run the Nagios check_disk command I get the correct values
# ../libexec/check_disk -w 10% -c 5% -p /usr/groups/sources
DISK WARNING - free space: /usr/groups/sources 44073 MB (9% inode=48%);|
/usr/groups/sources=409354MB;408084;430755;0;453427
But when you look at the graph the figures are all wrong
Has anyone else seen this? I was going to look at the usage to try and
forecast usage but it will now be very hard. I have just installed Nagios
Graph based on the default installation and using the default check_disk plugin.
Thanks
