0.8.7 w/MacTrack, Monitor, Discover-Data Source removed?

[cbboy]

Hello,

I'm running into a very different problem but I'm sure someone here will have the answer.

I have created interface graphs for all of my cisco switches. These graphs are created and working correctly until the next day. At some point the data source for the graph is being disconnected from the graph.

At first It looked like it was only doing this to admin down interfaces however this isn't the case.

Poller runs every 5min, MacTrack every 4hrs and discover disabled

Ideas? I have no errors per say in the log relevant to this, only snmp related to humidity oid's.

thx

The graph comes up with this error:
ERROR: invalid rpn expression in: a,8,*

example:

/usr/bin/rrdtool graph - \

RRDTool Says:

It would seem that all Data sources for interfaces that Cacti's status = down are removed

ideas?

Thank you!
