How to build the module¶

install libmaxminddb-devel package
set –enable-mmdblookup on configure
Configuration Parameter¶
Note
Parameter names are case-insensitive.
Module Parameters¶
container¶
type |
default |
mandatory |
|
---|---|---|---|
word |
!iplocation |
no |
none |
New in version 8.28.0.
Specifies the container to be used to store the fields amended by mmdblookup.
Input Parameters¶
key¶
type |

Name of field containing IP address.
mmdbfile¶
type |

Location of Maxmind DB file.
fields¶
type |
default |
mandatory |
|
---|---|---|---|
array |
none |
yes |
none |
Fields that will be appended to processed message. The fields will always be appended in the container used by mmdblookup (which may be overridden by the “container” parameter on module load).
By default, the maxmindb field name is used for variables. This can be overridden by specifying a custom name between colons at the beginning of the field name. As usual, bang signs denote path levels. So for example, if you want to extract “!city!names!en” but rename it to “cityname”, you can use “:cityname:!city!names!en” as field name.
Examples¶
Minimum configuration¶
This example shows the minimum configuration.
# load module
module( load="mmdblookup" )
action( type="mmdblookup" mmdbfile="/etc/rsyslog.d/GeoLite2-City.mmdb"
fields=["!continent!code","!location"] key="!clientip" )
Custom container and field name¶
The following example uses a custom container and custom field name
# load module
module( load="mmdblookup" container="!geo_ip")
action( type="mmdblookup" mmdbfile="/etc/rsyslog.d/GeoLite2-City.mmdb"
fields=[":continent:!continent!code", ":loc:!location"]
key="!clientip")
