I have syslog network messages successfully parsed with logstash,  
event 1 has [system][syslog][hostname]=10.20.0.3  
event 2 has [system][syslog][hostname]=10.111.0.3

however the following statements fail to match for 10.111.x.x, and never uses the last else statement.  
any ideas?

I'm trying to match as follows

```
   if [system][syslog][hostname] =~ /10\.111\..*/ {
   mutate { 
                add_field => { 
                          "[geoip][location][latitude]" => "77.777777"
                          "[geoip][location][longitude]" => "77.777777" 
                          } 
          }
      }  
   else if [system][syslog][hostname] =~ /10\.20\./ {
    mutate {
            add_field => {
                    "[geoip][location][latitude]" => "88.888888"
                    "[geoip][location][longitude]" => "88.888888"
                    }
            }
    }    
   else {
    mutate {
                add_field => {
                          "[geoip][location][latitude]" => "99.999999"
                          "[geoip][location][longitude]" => "99.999999"
                          }
                }
      }
```

You are testing [system][syslog][hostname], not [syslog][system][hostname]

sorry, that was a typo .. I meant that the fields as matched by grok should be [system][syslog][hostname]  
and discover console is showing this correctly

issue resolved:

I changed all my match statements to use .\* in the match

i.e.

```
"[system][syslog][hostname] =~ /10\.111\..*/"
"[system][syslog][hostname] =~ /10\.20\..*/"

```

all issues seemed to go away overnight... =) thx

```auto
