Gathers log information from a file
rsyslog::imfile { 'my-imfile':
file_name => '/some/file',
file_tag => 'mytag',
file_facility => 'myfacility',
}
e.g. rsyslog.d/10-puppetagent.conf - moves puppet-agent entries to a file and excludes from /var/log/messages
rsyslog::snippet { '10-puppetagent':
content => ":programname,contains,\"puppet-agent\" /var/log/puppetlabs/puppet/puppet-agent.log\n& ~",
}
The log_templates parameter can be used to set up custom logging templates, which can be used for local and/or remote logging. More detail on template formats can be found in the rsyslog documentation.
The following examples sets up a custom logging template as per RFC3164fmt:
class{'rsyslog::client':
log_templates => [
{
name => 'RFC3164fmt',
template => '<%PRI%>%TIMESTAMP% %HOSTNAME% %syslogtag%%msg%',
},
]
}The remote_servers parameter can be used to set up logging to multiple remote servers which are supplied as a list of key value pairs for each remote. There is an example configuration provided in ./test/multiple_hosts.pp
Using the remote_servers parameter over-rides the other remote sever parameters, and they will not be used in the client configuration file:
log_remoteremote_typeserverport
The following example sets up three remote logging hosts for the client:
class{'rsyslog::client':
remote_servers => [
{
host => 'logs.example.org',
},
{
port => '55514',
},
{
host => 'logs.somewhere.com',
port => '555',
pattern => '*.log',
protocol => 'tcp',
format => 'RFC3164fmt',
},
]
}Each host has the following parameters:
- host: Sets the address or hostname of the remote logging server. Defaults to
localhost - port: Sets the port the host is listening on. Defaults to
514 - pattern: Sets the pattern to match logs. Defaults to
*.* - protocol: Sets the protocol. Only recognises TCP and UDP. Defaults to UDP
- format: Sets the log format. Defaults to not specifying log format, which defaults to the format set by
ActionFileDefaultTemplatein the client configuration.
Events can also be logged to a MySQL or PostgreSQL database. The database needs to be deployed separately, either locally or remotely. Schema are available from the rsyslog source:
Declare the following to configure the connection:
class { 'rsyslog::database':
backend => 'mysql',
server => 'localhost',
database => 'Syslog',
username => 'rsyslog',
password => 'secret',
}
class { 'rsyslog::server': }

backend 'mysql','pgsql' Database backend (MySQL or PostgreSQL).

By default, rsyslog::server will strip numbers from hostnames. This means the logs of multiple servers with the same non-numerical name will be aggregrated in a single directory. i.e. www01 www02 and www02 would all log to the www directory.
To log each host to a seperate directory, set the custom_config parameter to 'rsyslog/server-hostname.conf.erb'
If any of the following parameters are set to false, then the module will not
manage the respective package:
gnutls_package_name
relp_package_name
rsyslog_package_name
This can be used when using the adiscon PPA repository, that has merged rsyslog-gnutls with the main rsyslog package.
Default package_status parameter for rsyslog class used to be 'latest'. However, it was against puppet best practices so it defaults to 'present' now.
