no graphs with rrdtool 1.1

kamanita · Post by **kamanita** » Mon Feb 21, 2005 12:00 pm

hi, i installed cacti for debian sarge, ossim and bind-mailgraph.
but i get no graphs only broken images ... on all systems, only ossim shows graphs.
the poller collects the data but there are no graphs.

if i turn on the debug mode i get the following messages:

ERROR: invalid rpn expression in: a,1024,*

or

ERROR: height > 32 is not possible with --only-graph option

has anybody any idea?

thanks

Yes, downgrade to rrdtool 1.0.49. 1.1.x is not for Productions, says it right on the rrdtool website.

same problem!

mmmh ... how can i check what rrdtool needs, if a library is missing and so on?

Did you update the path? Just making sure that cacti is using the 1.0.x version.

Can you post the debug of the graph generation?

path is the same (if you mean the rrdtool path settings in cact) as in the old version.

how to generate rrtool debug output. the only hint i have is the "debug" from the cacti interface!

To view the graph debug, click the little wrench next the the graph when viewing graphs.

there are two errors,

ERROR: invalid rpn expression in: a,1024,*

or

ERROR: height > 32 is not possible with --only-graph option

thats all ...

Please post the debug, I want to see how cacti structured your command line for rrdtool.

one debug ....
/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="server1 - Memory Usage" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="kilobytes" \
DEF:a="/usr/share/cacti/rra/localhost_mem_buffers_3.rrd":mem_buffers:AVERAGE \

GPRINT

You still appear to be running rrdtool 1.1 which is NOT supported. Please run "rrdtool --version" to verify. Also, verify that your setting in "Settings->Paths" refers to the correct version of RRDTOOL.

i am using rrdtool version 1.1
but other apps ... like ossim which also use rrdtool have no problems!
should i have both versions on one system?

Post by **rony** » Tue Feb 22, 2005 9:24 am

Up to you if you want to run both version.

But as we have said, cacti does not support rrdtool 1.1.x, please use rrdtool 1.0.x with cacti.

debian sarge, with cacti, bindgraph.cgi mailgraph.cgi and rrdtools 1.0.49 ... same problem ....

Have you waited at least 1 polling cycle? Have you confirmed permissions on the rra and log directory allow the polling user to access them?

i did ...
my question is ... is there any possible tools or command that i can use manually to see what happens whenn rrdtool starts .. or the cacti poller?
