Changing Centreon graph y-axis scale for used disk space

centreonmonitoringnagios

I am monitoring disk space use on Windows servers using the check_nt plugin (via the check_nt_disk command). This works just fine and I get some nice graphs as well.

The problem with the graph (storage template) is that the x-axis shows the disk space used rather than the total size of the disk, for example:

enter image description here

The check that is producing this data is effectively:

./check_nt -H 172.16.3.200 -p 12489 -s MyPassword -v USEDDISKSPACE -l d -w 80 -c 90

Which returns to nagios the following (I've split this over two lines on the pipe character):

d:\ - total: 19.55 Gb - used: 3.65 Gb (19%) - free 15.90 Gb (81%) | 
'd:\ Used Space'=3.65Gb;15.64;17.59;0.00;19.55

I know that the total disk space available is being recorded (19.55) but I don't know how to tweak the graph to use this as the y-axis scale.

Has anyone done this before?

I'm using Nagios 3.2.3 and Centreon 2.2 stable.

Update:

In reply to regilero, these are all the curves I have available:

These are all the templates:

Go to Views>Graphs>Curves, there you shoudl find your Curve 'd--Used-Space'. Edit this curve and check the box 'Print Max value'.

In your line 3.65Gb;15.64;17.59;0.00;19.55 you have in fact (value)(metric);(warn level);(crit level);(min level);(max level). So you need to graph as well the max value on this metrics.

You've got the lastest result from each call in the service detail. Takine any service in any status, if you click on the service name from the monitoring view you get the detail where you could find latest check results.

For example:

Service Status  OK
Status information  
Disk OK - / TOTAL: 19.686GB USED: 5.418GB (27%) FREE: 14.268GB (73%)
Performance Data    size=21137846272B used=5817847808B;16910277017;19024061644;0;21137846272
Current Attempt     1 / 3
State Type  HARD
Last Check Type     Active
Last Check  2011/05/18 - 13:59:24
Next Scheduled Active Check     2011/05/18 - 14:59:24
Latency     0.86 seconds
...

Here the performance data is: Performance Data size=21137846272B used=5817847808B;16910277017;19024061644;0;21137846272. It's in fact the last part returned in the check output (after the pipe).

To check how centreon handle that 'perfdata' you should Go to administration>Options>Centstorage>Manage, Here you can see for each service/host which metrics are extracted from the performance data string.

To get these metrics on a graph check that you've got it on Views>Graphs>Curves. You can easily create a new ones (with maybe not enought options, but for simple metrics it will be enough).

If the command works fine from command line check commands.cfg at nagios server for the check_nt UPTIME service and replicate it to your service command:

define command{
    command_name    check_nt_uptime
    command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v UPTIME
    }

define service{
    use                             windows.template
    host_name                       hostname
    service_description             Uptime
    check_command                   check_nt_uptime
    }
