perfsonar development work

Hi,

I changed the timestamp values and apparently the problem was solved.
But every time I want to execute the script I have to change the values (otherwise I’ll get the JAVA exception).

Luis Marta told me to put the “N” character instead of a number. Because on RRD context, the character “N” is the current time … well, it’s the “Now” time.
Currently, each time I execute the test-ma.sh script I don’t need to change the values.

I know this is *only* a test script but I think it could be a good idea to put the “N” character instead of a numeric value.
I think this is the best way to avoid JAVA exceptions regarding the time values.

Bellow you can find my current xml files:

Hello Miguel,

Please change the timestamp in your request message and try again.

Your request is asking the service to try to add new values to the rrd file. The service will make use of the timestamp provided in the request message. From the error message "/*Message: RRDUPDATE failed: illegal attempt to update using time 1139319941 when last update time is 1139319941* *(minimum one second step)"*/, it is clear that the rrd file already has a value entered previously for the timestamp 1139319941. The next value expected is anything greater that this value (not equal, not lesser).

Let us know if this solves the problem.

Loukik.

Hi all,

I installed the MA but I’m having some problems. When I execute the /test-ma.sh/ script I’m getting some JAVA exceptions regarding the RRD database.

Does anyone have any idea?

Here goes the output:
