Subject: [I2G2-Proto] Empty response from RRD MA

Hi,

I am getting empty response from our RRD MA, while rrdtool fetch
with the same parameters produces valid data. Does anybody have
any suggestion where can be the problem?

RRD MA configuration, request and response files are in attachments.

rrdtool fetch returns the following:

# rrdtool fetch /usr/local/snmp_mp/cesnet_gn2.rrd AVERAGE -r 60 -s
1159254960 -e 1159255080
                       bytes_in           bytes_out

1159255020: 9.4378377833e+06 8.5923076833e+06
1159255080: 1.1388552250e+07 1.0209844850e+07
1159255140: 1.1294331500e+07 9.4089445833e+06

Regards,

Sven Ubik
