stuck with ntop (CentOS 5.3)
I am trying to use ntop and install it as per these howto:
(installed and tested as per instructions)
in the a.m. howto it was not possible to use ntop at all, due to this error:
[.. lots of information ..]
configure: error: Unable to find RRD at /usr/local/rrdtool: please use --with-rrd-home=DIR
error; note that even with the proper "DIR" information it returns such error AND stops.
then I installed ntop with yum - all runs smoothly and ntop runs (apparently) normal here EXCEPT that, when asking for any graphic (network load, traffic) it doesnot show any graph, just this message:
"NOTE: this page is not operational when the RRD plugin is disabled, misconfigured or missing."
BUT.. these (and some others) are already enabled.
So, I am stuck: HOW can I got those nice graphics? think that it is closely related with those "Unable to find RRD at /usr/local/rrdtool", but I have nor error messages nor log's pointing me to the right direction.
Any hint, pls?
Did you see any errors when you built RRDTool?
no, but I managed to solve it and, using the debug tool got rrd to function.. but problem changed somewhat:
a) the summary/network loads shows the traditional "NOTE: this page is not operational when the RRD plugin is disabled, misconfigured or missing." besides it is properly configured/activated (think so).
b) if using the "info about" a particular host (all protocols/traffic, then any host) and click in the "historical data" icon (last line, right), it shows various empty chart, no data at all.
so.. I am still stuck.
That sounds like a permissions problem (like RRDTool is not allowed to write graphics to a certain directory). Did you check your log files?
