[rrd-users] graph is empty, not sure what I am doing wrong

2015-07-07 Thread Devante Vargas 
Hello,

I am working on using RRD to create some Citrix XenApp graphs to show
sessions states.No matter what I've done the graph gets created but no data
is populated into the graph, also how do I get it so that the vertical
column is not in increments of 0.2 but in real measurements of 1. I have
installed the rrdtool on the windows 2008 R2 server which is not a XenApp
server in the farm but I have also run it on a XenApp server and created
the rrd file using the following parameters:

C:\Perl\site\lib\auto\RRDs\rrdtool.exe create SessionState.rrd
--start now
--step 300
DS:Total:GAUGE:600:0:5
DS:Active:GAUGE:600:0:5
DS:Disconnected:GAUGE:600:0:5
DS:Idle:GAUGE:600:0:5
DS:Down:GAUGE:600:0:5
DS:Unknown:GAUGE:600:0:5
RRA:MIN:0.5:12:8760
RRA:MAX:0.5:12:8760
RRA:LAST:0.5:1:105500

I then connect to XenApp and launch a session and runt he update command
using the following:

c:\Perl\site\lib\auto\RRDs\rrdtool.exe update
f:\PSscripts\Common\Get-FarmData\DASHBOARD\DEV_Accounts\SessionState.rrd
N:2:1:1:0:0:0

Once its updated I run the following code to generate the graph:

D:\PSScripts\rrd\rrdtool.exe graph graphs/daily.png
--title DEVAccounts Citrix Daily Sessions
--vertical-label Sessions
--width 400
--height 100
--start end-1d
DEF:total=SessionState.rrd:Total:MAX
DEF:active=SessionState.rrd:Active:LAST
DEF:disconnected=SessionState.rrd:Disconnected:LAST
DEF:idle=SessionState.rrd:Idle:LAST
DEF:down=SessionState.rrd:Down:LAST
DEF:unknown=SessionState.rrd:Unknown:LAST
CDEF:LineTotal=total,1,*
CDEF:LineActive=active,1,*
CDEF:LineDisconnected=disconnected,1,*
CDEF:LineIdle=idle,1,*
CDEF:LineDown=down,1,*
CDEF:LineUnknown=unknown,1,*


Any help would be greatly appreciated.

Thank you,

 Once its updated

How many times/over what period did you run the updates ? You have a step size 
of 300s (5 minutes), and your most granular consolidated data for MIN and MAX 
is 12 times that (ie one hour). You'll need to run updates less than 600s (10 
minutes) apart until both of the following are true :
- You go past the hour, since your consolidated data points will all start 
end on the hour (ie 1am, 2am, and so on)
- You have more than 50% of the preceding primary data points filled.
This means you must be regularly updating for *AT LEAST* half an hour, and up 
to almost 1 1/2 hours depending on when you start, before you'll see data.

Use rrdtool fetch ... to see what data is available.
