Installs the rsyslog package, manages the rsyslog service and sets up basic configuration for a standalone machine.
Includes recipe[rsyslog]
.
Uses node['rsyslog']['server_ip']
or Chef search (in that precedence order) to determine the remote syslog server's IP address. If search is used, the search query will look for the first ipaddress
returned from the criteria specified in node['rsyslog']['server_search']
.
You can use node['rsyslog']['custom_config']
to define custom entries for sending logs to remote servers. Available attributes:
'server': Ip/hostname of remote syslog server (Required)
'port': Port to send logs to
'logs': Syslog log facilities to send (auth, authpriv, daemon, etc)
'protocol': Can be tcp or udp
'remote_template': Rsyslog template used for the messages
Example:
node['rsyslog']['custom_remote'] = [{ 'server' => '10.10.4.4', 'port' => '567', 'logs' => 'auth.*,mail.*', 'protocol' => 'udp', 'remote_template' => 'RSYSLOG_SyslogProtocol23Format'},
{ 'server' => '10.0.0.3', 'port' => '555', 'logs' => 'authpriv,daemon.*' } ]
The server key is required; if other keys are left out, the default global values will be used (eg node['rsyslog']['port']
will be used if 'port' is omitted)
If the node itself is a rsyslog server ie it has rsyslog.server
set to true then the configuration is skipped.
If the node had an /etc/rsyslog.d/35-server-per-host.conf
file previously configured, this file gets removed to prevent duplicate logging.
Any previous logs are not cleaned up from the log_dir
.
Configures the node to be a rsyslog server. The chosen rsyslog server node should be defined in the server_ip
attribute or resolvable by the specified search criteria specified in node['rsyslog']['server_search]
(so that nodes making use of the client
recipe can find the server to log to).
This recipe will create the logs in node['rsyslog']['log_dir']
, and the configuration is in /etc/rsyslog.d/server.conf
. This recipe also removes any previous configuration to a remote server by removing the /etc/rsyslog.d/remote.conf
file.
The cron job used in the previous version of this cookbook is removed, but it does not remove any existing cron job from your system (so it doesn't break anything unexpectedly). We recommend setting up logrotate for the logfiles instead.
The log_dir
will be concatenated with per_host_dir
to store the logs for each client. Modify the attribute to have a value that is allowed by rsyslogs template matching values, see the rsyslog documentation for this.
Directory structure:
<%= @log_dir %>/<%= @per_host_dir %>/"logfile"
For example for the system with hostname www
:
/srv/rsyslog/2011/11/19/www/messages
For example, to change this to just the hostname, set the attribute node['rsyslog']['per_host_dir']
via a role:
"rsyslog" => { "per_host_dir" => "%HOSTNAME%" }
At this time, the server can only listen on UDP or TCP.
Configures a text file input monitor to push a log file into rsyslog. Rsyslog must be installed to use this custom resource either using your own wrapper cookbook or the rsyslog::default recipe
Properties:
name
: name of the resource, also used for the syslog tag. Required.file
: file path for input file to monitor. Required.priority
: config order priority. Defaults to99
.severity
: syslog severity. Must be one ofemergency
,alert
,critical
,error
,warning
,notice
,info
ordebug
. If- undefined, rsyslog interprets this as
notice
. facility
: syslog facility. Must be one ofauth
,authpriv
,daemon
,cron
,ftp
,lpr
,kern
,mail
,news
,syslog
,user
,uucp
,local0
, ... ,local7
. If undefined, rsyslog- interprets this as
local0
. cookbook_source
: cookbook containing the template. Defaults torsyslog
.template_source
: template file source. Defaults tofile-input.conf.erb
Use recipe[rsyslog]
to install and start rsyslog as a basic configured service for standalone systems.
Use recipe[rsyslog::client]
to have nodes log to a remote server (which is found via the server_ip
attribute or by the recipe's search call -- see client)
Use recipe[rsyslog::server]
to set up a rsyslog server. It will listen on node['rsyslog']['port']
protocol node['rsyslog']['protocol']
.
If you set up a different kind of centralized loghost (syslog-ng, graylog2, logstash, etc), you can still send log messages to it as long as the port and protocol match up with the server software. See Examples
Use rsyslog_file_input
within your recipes to forward log files to your remote syslog server.
A base
role (e.g., roles/base.rb), applied to all nodes so they are syslog clients:
name "base"
description "Base role applied to all nodes
run_list("recipe[rsyslog::client]")
Then, a role for the loghost (should only be one):
name "loghost"
description "Central syslog server"
run_list("recipe[rsyslog::server]")
By default this will set up the clients search for a node with the loghost
role to talk to the server on TCP port 514. Change the protocol
and port
rsyslog attributes to modify this.
If you want to specify another syslog compatible server with a role other than loghost, simply fill free to use the server_ip
attribute or the server_search
attribute.
Example role that sets the per host directory:
name "loghost"
description "Central syslog server"
run_list("recipe[rsyslog::server]")
default_attributes(
"rsyslog" => { "per_host_dir" => "%HOSTNAME%" }
)
Default rsyslog options are rendered for RHEL family platforms, in /etc/rsyslog.d/50-default.conf
with other platforms using a configuration like Debian family defaults. You can override these log facilities and destinations using the rsyslog['default_facility_logs']
hash.
name "facility_log_example"
run_list("recipe[rsyslog::default]")
default_attributes(
"rsyslog" => {
"default_facility_logs" => {
'*.info;mail.none;authpriv.none;cron.none' => "/var/log/messages",
'authpriv' => '/var/log/secure',
'mail.*' => '-/var/log/maillog',
'*.emerg' => '*'
}
}
