Hobbit-perl client Oracle question

Hi,

My MemReq test is showing the following results:

Memory Request Check (warning >= 90%,alert >= 95%). red 6 Request failures, Last Failed size is 3128. Free Space is 23.9M, AVG Free Space is 108.8K, Used Space is 656.1K, AVG Used Space is 2.9K.

I have two doubts: 1 - In dbcheck.ini how to define the thresolds for the memreq ? Memory Request Check (warning >= 90%,alert >= 95%). 2- I have 6 request failures but the graph shows me always 0.0, It's percentage measure or a integer value graph?the others values are printing ok.

Thanks in advance,

Mario Panza.
