poller.php problem when updating data in RRD

[paulmiles01]

Hello,

I'm new to Cacti and this particular problem has me stumped.

I'm running Cacti 0.8.7b on Redhat 4, using RRDTool version 1.2.23.

I've created my own custom scripts that execute fine, and everything looks good except for some reason, the result of the script is not being added to the RRD.

[root@142498-db1 cacti]# php -q poller.php --force --debug | more

/rra/app2_traffic_in_59.rrd --template traffic_out:traffic_in 1214918174:3673193498:3673193498

In the the 1st rrdtool update line, it ommits the rrdname, which is causing the update statement to fail.
The second rrdtool update line has the rrdname (traffic_out:traffic_in)

My question is, where is this rrdname set? Are there any restrictions on size/characters in it.

For completeness, please see this extract from cacti.log

Please visit the data source related to the failing rrd file and post a screenshot. Then, please visit the associated graph at graph management and post the second screenshot

This script call shows the return of only one single parameter, whereas the Data Source defines 4 of them (In fact, the screenshot shows the wrong data source, it is id=90 instead of id=80).
