Hi,

I have the following code, but the ruby code is not working for detecting numeric values. So all fields are strings:

input {  
tcp {  
host =\> "172.30.19.177"  
port =\> 5000  
type =\> syslog  
}  
udp {  
port =\> 5000  
type =\> syslog  
}  
}

filter {  
if [type] == "syslog" {  
mutate {  
gsub =\> [  
"message", "= ", '="" '  
]  
}  
kv {  
include\_brackets =\> false  
}  
ruby {  
code =\> "  
event.to\_hash.keys.each { |k|  
if k.start\_with?('cnt\_')  
event[k] = event[k].to\_i  
end  
}  
"  
}  
geoip {  
source =\> "dst\_ip"  
}  
}  
}

output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
}  
}

Please show an example event that isn't processed correctly. Please show what it looks like using a `stdout { codec => rubydebug }` output.
