Good afternoon, my problem surely has an easy solution but I have not been able to solve it.
When parsing the logs, it puts quotes in the first and last column and I wish they did not appear.
Thanks in advance

It looks like the quotes are part of the log message you are parsing.  Try declaring the quotes as constants in your pattern.  Something like:

"%s{ip} - ... %s{datos}"%n

Hope that helps,

Toby
