Sagi,

Your idea was right, so I only had to do a little adjust.

{code => "event['test'] = event['reqsecs'].to_f * 1000000"}

Thank you,

Matheus,
This is probably because "reqsecs" field is set as string and not integer. Try this one:
ruby
{ code => "event['test'] = Integer(event['reqsecs']) * 1000000" }

and if this doesn't work:
ruby
{ code => "event['test'] = String(Integer(event['reqsecs']) * 1000000)" }

Basically Integer() converts a string to an integer (AFAIK, overflow is not an issue since ruby's integers are implemented in software).
String() converts everything to string.

Hi,

thank you for your help.

ruby {
code => "event['test'] = event['reqsecs'] * 1000000"
}

I tried the above code, but the result was reqsecs repeated one million times.
