RE: [php-weathermap] problem reading rrd files

["Holemans Wim" <wim.holemans@xxxxxxxx>]

Already found the reason of the problem ; seems that something went
wrong during the installation and some directories were not expanded ;
reinstalled everything, made the rrdtool change and my first graph came
out,...  not yet what I expected, values are much to big, but I remember
reading something about bits and bytes in the doc, so I'll first search
the doc before coming back to the list.

Subject: [php-weathermap] problem reading rrd files

 

We have a inhouse made management system and we used the grnet network
weathermap tool (both php and perl version) until now.

Seeing the new options in the php-weathermap version, I wanted to
convert our scripts to use this version, but I always get the same error
(after sorting out all the changes/differences in function names and
parameters) :

I can't find the source of the problem. If I run the check.php script, i
don't get any error except for imagefilter, but that has nothing to do
with this problem. I changed the path of rrdtool in wheathermap to
/usr/bin/rrdtool and I checked the names of the DS with rrdtool info :

 

filename = "/uanet/oper/data/stats/cde/ldsys01/Po40.rrd"

rrd_version = "0003"

step = 300

last_update = 1214392563

ds[InOctets].type = "COUNTER"

ds[InOctets].minimal_heartbeat = 600

ds[InOctets].min = NaN

ds[InOctets].max = NaN

ds[InOctets].last_ds = "4947781988403"

ds[InOctets].value = 2.3237924688e+07

ds[InOctets].unknown_sec = 0

ds[OutOctets].type = "COUNTER"

ds[OutOctets].minimal_heartbeat = 600

ds[OutOctets].min = NaN

ds[OutOctets].max = NaN

ds[OutOctets].last_ds = "5009074512370"

ds[OutOctets].value = 2.3762879703e+07

ds[OutOctets].unknown_sec = 0

 

Anyone has a clue what is still going wrong or where to look for more
info ? Things to try ? I'm no php specialist.
