can't associate thold with specific data source

[noproblem]

Good morning,

I'm using cacti to graph information related to Cisco CBQOS, for this I have 2 data sources inside one RRD:
qos_bytes and qos_drops (both in bytes per second)

Although in the graph everything is as expected, in thold I get this behaviour:
- if I set the data type to exact, I get a negative value apparently with no connection to the ammount of traffic (tried passing to bps, etc)
- when it didn't work, I changed to an RPN Expression (|ds:qos_drops|:LAST) instead of getting the drop rate, it's returning the qos_bytes value....

In attach follows a screenshot.
Also another output (please let me know if there is any other that would help):

Code: Select all

Can someone help with figuring out what is wrong?
Thanks in advance.

Just to add some more information:

Code: Select all

[XXX@localhost scripts]# rrdtool fetch /usr/share/cacti/rra/XXXXXX_qos_bytes_81.rrd LAST -r 300 -s -10m
                      qos_bytes           qos_drops

1328192400: 4.5066719511e+04 9.9232801335e+03
1328192700: 4.4925396526e+04 9.9559184933e+03

whatever I do, I keep getting the first value and cannot collect the second. Perhaps with a better understanding of RPN Expressions can help out.

Thanks again for any help.
Cheers

nobody can help? Tried changing thold versions and still getting unexpected behaviour

Any suggestions?

Thanks
