page in the web interface:UNWANTED
.bytes
. You could use a pattern like:type
, bytes
, and errors
. Even not naming the first and last patterns wouldstill create a field names BASE10NUM
. In order to ignore fields, but still require matching them use UNWANTED
:bytes
while making sure the entire pattern must match.len
is an integer and would like to make sure it is stored with that data type, so we canlater create field graphs with it or access the field’s statistical values, like average etc.;datatype
at the end of the pattern, like:Type | Range | Example |
---|---|---|
byte | -128 … 127 | %{NUMBER:fieldname;byte} |
short | -32768 … 32767 | %{NUMBER:fieldname;short} |
int | -2^31 … 2^31 -1 | %{NUMBER:fieldname;int} New paint x 1 0. |
long | -2^63 … 2^63 -1 | %{NUMBER:fieldname;long} |
float | 32-bit IEEE 754 | %{NUMBER:fieldname;float} |
double | 64-bit IEEE 754 | %{NUMBER:fieldname;double} |
boolean | true, false | %{DATA:fieldname;boolean} |
string | Any UTF-8 string | %{DATA:fieldname;string} |
date | See SimpleDateFormat | %{DATA:timestamp;date;dd/MMM/yyyy:HH:mm:ssZ} |
datetime | Alias for date |
key=value
pairs into Graylog message fields without having to specify all possible key names oreven their order. This is how you can easily do this:message
. (Or any other string field that containskey=value
pairs.) Configure the extractor to store the (copied) field value to the same field. In this case message
. Thetrick is to add the “Key=Value pairs to fields” converter as last step. Because we use the “Copy Input” extractor, the converterwill run over the complete field you selected and convert all key=value
pairs it can find.dstip

and yet others use destination-address

Mar9
and Mar10
and end up having problems defining a parser string for that. Or maybe you havesomething else that is really exotic like just last wednesday as timestamp. The flexible date converter is accepting anytext data and tries to build a date from that as good as it can.
