# Master virtlogd daemon configuration file # ################################################################# # # Logging controls # # Logging level: 4 errors, 3 warnings, 2 information, 1 debug # basically 1 will log everything possible # # WARNING: USE OF THIS IS STRONGLY DISCOURAGED. # # WARNING: It outputs too much information to practically read. # WARNING: The "log_filters" setting is recommended instead. # # WARNING: Journald applies rate limiting of messages and so libvirt # WARNING: will limit "log_level" to only allow values 3 or 4 if # WARNING: journald is the current output. # # WARNING: USE OF THIS IS STRONGLY DISCOURAGED. #log_level = 3 # Logging filters: # A filter allows to select a different logging level for a given category # of logs. The format for a filter is one of: # # level:match # level:+match # # where 'match' is a string which is matched against the category # given in the VIR_LOG_INIT() at the top of each libvirt source # file, e.g., "remote", "qemu", or "util.json". The 'match' in the # filter matches using shell wildcard syntax (see 'man glob(7)'). # The 'match' is always treated as a substring match. IOW a match # string 'foo' is equivalent to '*foo*'. # # If 'match' contains the optional "+" prefix, it tells libvirt # to log stack trace for each message matching name. # # 'level' is the minimal level where matching messages should # be logged: # # 1: DEBUG # 2: INFO # 3: WARNING # 4: ERROR # # Multiple filters can be defined in a single @log_filters, they just need # to be separated by spaces. Note that libvirt performs "first" match, i.e. # if there are concurrent filters, the first one that matches will be applied, # given the order in @log_filters. # # For the virtlogd daemon, a typical need is to capture information # from the logging code and some of the utility code. Some utility # code is very verbose and is generally not desired. A suitable filter # string for debugging might be to turn off object, json & event logging, # but enable the rest of the util and the logging code: # #log_filters="1:logging 4:object 4:json 4:event 1:util" # Logging outputs: # An output is one of the places to save logging information # The format for an output can be: # level:stderr # output goes to stderr # level:syslog:name # use syslog for the output and use the given name as the ident # level:file:file_path # output to a file, with the given filepath # level:journald # output to journald logging system # In all cases 'level' is the minimal priority, acting as a filter # 1: DEBUG # 2: INFO # 3: WARNING # 4: ERROR # # Multiple outputs can be defined, they just need to be separated by spaces. # e.g. to log all warnings and errors to syslog under the virtlogd ident: #log_outputs="3:syslog:virtlogd" # # The maximum number of concurrent client connections to allow # on primary socket #max_clients = 1024 # The maximum number of concurrent client connections to allow # on administrative socket #admin_max_clients = 5 # Maximum file size before rolling over. Defaults to 2 MB # # Beware that a logrotate config file might be installed too, # to handle cases where virtlogd is disabled. To ensure that # the logrotate config is a no-op when virtlogd is running, # make sure that max_size here is smaller than size listed # in the logrotate config. #max_size = 2097152 # Maximum number of backup files to keep.
