trying to get 95th percentile graphs going for some my interfaces;
searched in the forums and google but did not find anything useful
or current.

anyone currently doing this? is so would you mind sharing?

And I found my error:

2012-05-17T13:58:21 ERROR RenderServer Failed to generate a graph

Traceback (most recent call last):

  File "/usr/local/zenoss/zenoss/Products/ZenRRD/RenderServer.py", line 155, in render

    rrdtool.graph(*gopts)

error: Not a valid vname: ifInOctets in line VDEF:in95=ifInOctets,95,PERCENT

Well, I take the Linux SNMP working back. It appears it has a problem with SNMP. It's working with Windows WMI and Linx SSH but NOT anything with SNMP.

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.

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..!

-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

LINE2:out95#00ccff:95th % Out

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.
