[rrd-users] Re: No data man

[NAIL, THOMAS (SBIS)]

Thanks for the timely response, Tobi. The data I'm parsing is simply a
colon-separated list of  values. Here is an example:

someplc:switched:43
thisplc:switched:142
anothplc:switched:25
notaplc:dedicated:12
nearaplc:dedicated:8
bytheplc:dedicated:11

also, I have attached a portion of the truss output (truss-file.txt). I hope
you can get more out of it than I did...

Thanks again,

Tom Nail

Today you sent me mail regarding [rrd-users] No data man:

*> 
*> Tobi, et al.
*> thanks for designing this wonderful tool...but (you knew it was coming,
*> right?) I'm having some problems. I'm trying to graph some data and it
isn't
*> showing up. Admittedly, Im a newbie and am probably missing something
*> simple, so I'll try to include as much information as I can. Sorry if
it's a
*> long post.
*> 
*> I'm using a simple perl script to get values from a current logfile and
*> update an rrd with the specific data. The script runs fine and I
encounter
*> no errors at that end, but the data doesn't appear in the rrd. I just
keep
*> getting "NaN". The script updates only once a day (thus the large values
for
*> the --step and heartbeat variables) and a "truss -fa" of the script shows
*> that it is indeed passing the correct variables from the parsing it has
*> done. I'm totally at a loss.
*> 

the program looks fine, but it would be interesting to see the
numbers you are feeding to rrdtool update ...
