Hi All,

I am also attempting to get the 95th percentile graph working in Zenoss and I have applied the same custom graph....


VDEF:in95=ifHCInOctets,95,PERCENT
VDEF:out95=ifHCOutOctets,95,PERCENT
COMMENT:\s
COMMENT:95th %ile over current period\: \n
HRULE:in95#00ff00:95th % In
GPRINT:in95:= \t %0.2lf%Sbps \n
HRULE:out95#ff00ff:95th % Out
GPRINT:out95:= \t %0.2lf%Sbps


However, the graphs breaks and does not display at all.    I understand the VDEF and its purpose, also HRULE and GPRINT.
My question is, why is the graph not displaying at all ?    Is there a syntax issue somewhere in the custom script ? or am I just missing something ??? 

Need some assistance as I am totally stuck.!.   It seems to work for everyone else here, but it's not working at all for me. !     

Thanks!!

Doug Reid.

Did you delete the old RRD file? Is a new one being created? I think changes to graphs mean you have to regenerate the RRD files.

Hi James!

I check the zpoectl logs and found this error, the graph is not being created because of a bad function string for VDEF:out95=ifHCOutOctets,95,PERCENT
I double checked the RRD files and they are fine. Would they still need to be deleted and then regenerated in this case ??

For clarity, here is the detailed output that generated the error:  This is for the Throughput graph where the custom script is being applied::

Thanks James!    Any thoughts you may have woud be extremely helpful..!

Hi all,

Just as an after thought:  I took the liberty taking a snapshot of the throughput graph commands before I started messing with it:

Here is what it is now:
-F
-E
--height=100
--width=500
--lower-limit=0
--rigid
--vertical-label=bits/sec
DEF:ifHCInOctets-raw=rrdPath/ifHCInOctets_ifHCInOctets.rrd:ds0:AVERAGE
DEF:ifHCInOctets-raw-max=rrdPath/ifHCInOctets_ifHCInOctets.rrd:ds0:MAX
CDEF:ifHCInOctets=ifHCInOctets-raw
LINE1:ifHCInOctets-raw#00cc00ff:ifHCInOctets 
GPRINT:ifHCInOctets-raw:LAST:cur\:%5.2lf%s
GPRINT:ifHCInOctets-raw:AVERAGE:avg\:%5.2lf%s
GPRINT:ifHCInOctets-raw-max:MAX:max\:%5.2lf%s\j
DEF:ifHCOutOctets-raw=rrdPath/ifHCOutOctets_ifHCOutOctets.rrd:ds0:AVERAGE
DEF:ifHCOutOctets-raw-max=rrdPath/ifHCOutOctets_ifHCOutOctets.rrd:ds0:MAX
CDEF:ifHCOutOctets=ifHCOutOctets-raw
LINE1:ifHCOutOctets-raw#0000ff99:ifHCOutOctets
GPRINT:ifHCOutOctets-raw:LAST:cur\:%5.2lf%s
GPRINT:ifHCOutOctets-raw:AVERAGE:avg\:%5.2lf%s
GPRINT:ifHCOutOctets-raw-max:MAX:max\:%5.2lf%s\j
HRULE:0#00ff00:95


It is missing these CDEF's
CDEF:ifHCInOctects-rpn=ifHCInOctects-raw,8,*
CDEF:ifHCInOctects-rpn-max=ifHCInOctects-raw-max,8,*
CDEF:ifHCInOctects=ifHCInOctects-rpn
CDEF:ifHCOutOctects-rpn=ifHCOutOctects-raw,8,*
CDEF:ifHCOutOctects-rpn-max=ifHCOutOctects-raw-max,8,*
CDEF:ifHCOutOctects=ifHCOutOctects-rpn

this is wrong
LINE1:ifHCInOctets-raw#00cc00ff:ifHCInOctets

it should be:
AREA:ifHCIOctects-rpn#00cc00ff:Inbound
HRULE should not be there. 

How would I go about repairing the graph commands to get back to the original settings ??

Any comments are appreciated. !

Thanks.
Doug.

This is the custom graph definition that I use for the Throughput graph and it works well...

VDEF:in95=ifInOctets,95,PERCENT
VDEF:out95=ifOutOctets,95,PERCENT
COMMENT:\s
COMMENT:95th percentile over current period\: \n
LINE2:in95#ff9900:95th % In
GPRINT:in95:= %0.2lf%Sbps \n
LINE2:out95#00ccff:95th % Out
GPRINT:out95:= %0.2lf%Sbps \n

The names of the datapoints need to be modified for 64bit templates.  I took Chet's examples and modified them to make them look better.
