Re: [rrd-users] Parameter problem - was: LAST always returning zero

Well, it is acting up again. I seem to be occasionally getting an extra row
of nan's. Given the previous column description:

1. The desired inverted value
2. A straight 'LAST' with no IF
3. A CDEF with an IF that instead normalizing nan to 1 and inverting,
prints -1 for nan, or the actual value. I then add a VDEF LAST for this
CDEF (GPRINT complains if I use the CDEF).
4. Timestamp of 2.
5. Timestamp of 3.

There's a clear pattern here.

I am randomly getting:

--end = 1205180908
queue2 0 0 -1 1205180900 1205180920

When it works correctly, I see:

--end 1205181178
queue2 1 0 1 1205181180 1205181180

Another failure:

--end 1205181288
queue2 0 0 -1 1205181280 1205181300


Success:

--end 1205181438
queue2 1 0 0 1205181440 1205181440


Failure:

--end 1205181508
queue2 0 0 -1 1205181500 1205181520


Success

--end 1205181658
queue2 1 0 0 1205181660 1205181660

I printed out rows for the failures with rrdtool fetch, and everything is
there.

If I change the --end forumla to /10*10-12, I see exactly the same results
as above.

Same thing if I change it to -22.

Ditto if I cange it to -32, so I don't think it is due to a slow rrd
update..
