95th Percentile

[danabersoch]

Hi Guys, I have seen that a few people have had issues with nth percentile graphing but can't see a common fix and I am under a lot of pressure to get this sorted asap.

My issue is that a Interface - Traffic (bits/sec) graph works fine and is viewable but when I try using the Interface - Traffic (bits/sec, 95th Percentile) on the same interface the graph doesn't display.

I have tried this for a Cisco Switch and Cisco ASA and it doesn't work (when the normal graph does).

I read somewhere that I need to manually change the Data Source, this made sense as the data source is "Interface - Traffic" for the normal graph and the 95th perc graph, the problem is that there was nothing obvious to change it too (no 95th percentile option).

Here is the version info:
Cacti Version 0.8.7h
Cacti OS unix
SNMP Version NET-SNMP version: 5.5
RRDTool Version RRDTool 1.3.x



Here is the debug for the 95th percentile graph:

Hi,

I have the same issue in version 0.8.8a. When i turn on the debug for the graph i also get "RRDTool Says:" but nothing below that title. Normally it should say OK. I also made some tests with cisco switches and ASA firewall.

When i load the page in the tree where the device/graph is located, i get the following error in apache logging for each graph: "sh: -c: line 1: syntax error: unexpected end of file". But i can't locate the file causing the error entry.

Can you verify you apache error log as well?
Maybe some other cacti users can help???

Thanks
