all graphs are blank

[henders254]

I am running cacti-0.8.7d-1.1 on OpenSUSE 11.1 with rrdtool version 1.3.4-1.27.1 and trying to graph my switch. But all the graphs are coming empty. I am polling 5 minutes interval via crontab and running cacti for two days. I have run php /srv/www/htdocs/cacti/poller.php from the CLI and get the shell back. There are lots of .rrd files under /srv/www/htdocs/cacti/rra/ with permission root:root (guess they were created by cacti)

I can graph the switch via MRTG (I don't run RRD with MRTG) and can also get information out of the switch via snmpwalk (version 2).

In cacti, I selected the device with Host Template "Generic SNMP-enabled Host" and also selected SNMP version 2.

When I went to graph management, I was presented with all the interfaces (100 of them in total) for this switch and I asked it to graph traffic in and out and selected graph templte as "Interface - Traffic (bits/sec)"

I went to Graph Management, viewed a single Graph, pressed the "Debug" link and here is what I found:

Code: Select all

RRDTool Command:

/usr/bin/rrdtool graph - \

RRDTool Says:

OK

Is this an issue with RRDTool not using TTF fonts? If so, how can I resolve this?

Thanks for any help.

All sounds / looks good so far. Post a screenshot of what you mean.

Make sure you have a valid rrdtool font defined in cacti's settings.
Also follow http://docs.cacti.net/manual:087:4_help ... #debugging

This is what I get.

Also, after I changed the crontab entry from "*/5 * * * * php /srv/www/htdocs/cacti/poller.php > /dev/null 2>&1" to */5 * * * * /usr/bin/php /srv/www/htdocs/cacti/poller.php > /dev/null 2>&1, I am getting the following (green vertical bars) for some of the graphs.

The font path in Cacti is empty. What should I put there?

Thanks.

A path to a valid font... i.e. on Windows: C:/WINDOWS/Fonts/VeraMono.ttf
