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': }
class { 'rsyslog::server':
enable_tcp => true,
enable_udp => true,
enable_relp => true,
enable_onefile => false,
relay_server => false,

custom_config => undef,

ssl_ca => undef,
ssl_cert => undef,
ssl_key => undef,
log_templates => false,

}
Both can be installed at the same time.

custom_config STRING Specify your own template to use for server config. Defaults to undef. Example usage: custom_config => 'rsyslog/my_config.erb'
content STRING Specify the content of the server config, instead of using a template. Defaults to undef.
port STRING/INTEGER Port to listen on for messages via UDP and TCP. Defaults to 514
relp_port STRING/INTEGER Port to listen on for messages via RELP. Defaults to 20514
address STRING The IP address to bind to. Applies to UDP listener only. Defaults to '*'.

log_templates HASH Provides a hash defining custom logging templates using the `$template` configuration parameter. Defaults to false.
log_filters HASH Provides a hash defining custom logging filters using the `if/then` configurations parameter. Defaults to false.
actionfiletemplate STRING If set this defines the `ActionFileDefaultTemplate` which sets the default logging format for remote and local logging. Defaults to false.
rotate STRING Enables rotation of logfiles. Valid values: year, month, day. Defaults to undef.
RSYSLOG::CLIENT CLASS PARAMETERS VALUES DESCRIPTION
-------------------------------------------------------------------
log_remote true,false Log Remotely. Defaults to true.
spool_size STRING Max size for disk queue if remote server failed. Defaults to '1g'.
remote_type 'tcp','udp','relp' Which protocol to use when logging remotely. Defaults to 'tcp'.
remote_forward_format STRING Which forward format for remote servers should be used. Only used if remote_servers is false.
log_local true,false Log locally. Defaults to false.
log_auth_local true,false Just log auth facility locally. Defaults to false.
split_config true,false Splits the client config into 00_client_config.conf, 50_client_remote.conf and 99_client_local.conf. Defaults to false.
custom_config STRING Specify your own template to use for client config. Defaults to undef. Example usage: custom_config => 'rsyslog/my_config.erb'
custom_params TODO TODO
server STRING Rsyslog server to log to. Will be used in the client configuration file. Only used, if remote_servers is false.
port '514' Remote server port. Only used if remote_servers is false.
remote_servers Array of hashes Array of hashes with remote servers. See documentation above. Defaults to false.
ssl_ca STRING SSL CA file location. Defaults to undef.
ssl_permitted_peer STRING List of permitted peers. Defaults to undef.
ssl_auth_mode STRING SSL auth mode. Defaults to anon.
log_templates HASH Provides a has defining custom logging templates using the `$template` configuration parameter.

actionfiletemplate STRING If set this defines the `ActionFileDefaultTemplate` which sets the default logging format for remote and local logging.
high_precision_timestamps true,false Whether or not to use high precision timestamps.
rate_limit_burst INTEGER Specifies the number of messages in $rate_limit_interval before limiting begins. Defaults to undef.
rate_limit_interval INTEGER Specifies the number of seconds per rate limit interval. Defaults to undef.
RSYSLOG::DATABASE CLASS PARAMETERS VALUES DESCRIPTION
-------------------------------------------------------------------
backend 'mysql','pgsql' Database backend (MySQL or PostgreSQL).
server STRING Database server.
database STRING Database name.
username STRING Database username.
password STRING Database password.
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.
