[mrtg] mrtg-rrd : all time stamps are showing nan

[Shane Webster]

Versions:
    MRTG -- 2.17.0
    RRDTool -- 1.4.4
(Both of these were compiled and not installed with a package manager. )

I am working on setting up a replacement MRTG server for our existing MRTG server that uses the MRTG Log files. Currently at this moment the test MRTG server is polling 7,500 devices. I believe what I am doing is a simplistic poll of the up/down for the interface of a device.

when I "fetch" or "dump" an RRD I get "nan" for ds0 and ds1 for all epochs.

I have searched the internet and re-read both the MRTG documentation and the RRDTools documentation in anticipation that I had missed something. Using google has not shed any light on this either.

---End of SNIP---

At this point I'm keeping it this simple while building it out.

In the logs I am seeing the following

---------------

2010-12-22 13:40:40 -- --log:  got: ???/???

This example is a "create" because I had removed all my RRD's (stupidly) and started fresh again, but I assure you the updates looked nearly identical just with out the "create"

Any help would be appreciated, if there is anything else I can provide such as a dump or a info please let me know.

Thank you,
    Shane Webster
