Hi all,

I am getting "No match" results from our MA. I guess that it can be
related to RRD file format required by MA. I created RRD file like this:

rrdtool create myrouter.rrd --start 0 --step 1 \
        DS:in:COUNTER:5:U:U \
        RRA:AVERAGE:0.5:1:60 \
        RRA:AVERAGE:0.5:5:60

and I am filling it like this:

while true; do
  snmpget -v 2c -c commodity r85.cesnet.cz ifInOctets.72 > tmp

  # $timestamp obtained and $in extracted here

  rrdtool update myrouter.rrd $timestamp:$in
  sleep 1;
done

I can query RRD by fetch:

rrdtool fetch myrouter.rrd AVERAGE -s 1135004260 -e 1135004275 -r 5

1135004265: 2.2407650400e+07
1135004270: 2.1342136200e+07
1135004275: 4.6648000000e+03

But when I try the same query from Java test client with these parameters:

 <select:parameter name="startTime">1135004260</select:parameter>
 <select:parameter name="endTime">1135004275</select:parameter>
 <select:parameter name="consolidationFunction">AVERAGE</select:parameter>
 <select:parameter name="resolution">5</select:parameter>

I get:

<perfsonar:datum value="No Match" /></perfsonar:data>

I am getting the same result from Python client.

Our service.properties on MA includes:

# location of rrd configuration file
service.ma.rrd.conf_file=/usr/local/sonar/perfsonar/conf/cesnet.xml

Attached are these files:

client-run-targets.xml         for "ant run-cesnet"
cesnet.xml                     refered from service.properties on MA
SetupDataRequest.xml           request
response.xml                   response

Can anybody advice me where I did error in my configuration?

Could you send me your rrdtool create command?

Thanks a lot.

Regards,

Sven Ubik
