Hi,

Within Zenoss 3.x, I need to get graphs out of Zenoss' RRD files. I can for sure use "rrdtool graph" from my python script, but I would prefer to use the Zenoss renderer process with some smart URLs like

     http://localhost:8080/zport/RenderServer/render/$device/$interface/$width/$height http://localhost:8080/zport/RenderServer/render/$device/$interface/$width/$height

Is this foreseen ? and possible ?
Example welcome...

TIA,
Charles

Thanks James, right on the spot !
I'm only wondering... the encoding might change with the next zenoss upgrade...
A well-defined web service would definitly be valuable.

Have a look at this: http://community.zenoss.org/message/68274#68274 http://community.zenoss.org/message/68274#68274

I create an external web front-end for custom interface graphs. Included in this front-end is a cgi script that takes human readable urls and post it to the zenrender to display graphs.

An image url would look something like this:

https://localhost/zenrrd/cgi-bin/zenoss_rrd.cgi?device=$device&int=$interface&end=08/15/2012&start=08/01/2012&width=800 https://localhost/zenrrd/cgi-bin/zenoss_rrd.cgi?device=$device&int=$interface&end=08/15/2012&start=08/01/2012&width=800

Thanks, nice attempt. meanwhile, I have written a web-service that pulls data out from RRD files, similar to your stuff. I know as well how to get rid of the sudo : use PHP and per-directory user-rights, will take me some more time to implement.

No problem. I just wanted to share this as it might of been useful, even if the interface was not needed, it might have some useful bits. It definitely isn't perfect as it was written in a day.

As for sudo, I am guessing you are refering to the bash script? Sudo isn't needed, but I just didn't want to tell people to change permissions on their machines. That is what I did at first, but didn't like the idea. The bash script could just be run in cron as the zenoss user instead if the permissions were right.

I also figured this might not be as useful for others if it didn't include other graphs like packets, errors, cpu, memory... so I am currently looking into that.
