[Omnetpp-l] Scave Tool Manual or Examples?

[Gürkan]

Hello,

I would like to know if there is a manual for Scave Tool?
Or some more examples than in the omnet manual.

What I want to do is the following:
For each host vector there is a mean value (besides the columns Module, Name, StdDev, Variance), that shows the mean over some values of the vector. I would like to generate an output that is a collection of these mean values.

Thank you very much,

Gürkan

I also have the same issue with you. 

I wish if there 's any body can answer.

I haven't  found any manual for scavetool beside the Omnet++ manual. However, I had a similar issue, and this is how I solved the problem:

I wanted to compute the average of a value over time. I added a @statistic declaration to the NED file of the module that is supposed to collect the statistic, specifying "record = stats":

@signal[hopDistance](type = "int");
@statistic[hopDistanceFromSource_](source = "hopDistance"; record = stats);

Now, when you are done with the simulations, you can access the mean by using:

scavetool scalar -p "module(yourModule) AND name(\"hopDistanceFromSource_:stats:mean\")" -O output.csv result-*.sca

The name of the string to use in the "name" option in scavetool can be found by inspecting the .sca file though text search.

HTH,

Gianluca
