NAME
aminerremotecontrol - lightweight tool for log checking, log analysis
SYNOPSIS
aminerremotecontrol [[--exec command] | [--exec-file file]] [OPTIONS]...
DESCRIPTION
This manual page documents briefly the aminerremotecontrol command. The command executes
arbitrary remote control commands in a running aminer child process. As child process is
usually running with lowered privileges or SELinux/AppArmor confinement, you may observe
unexpected results when accessing resources outside the child process, e.g. files. For
more details see also packaged documentation at /usr/share/doc/logdata-anomaly-miner.
Example usecases:
Print a property of the running AminerConfig:
/usr/bin/aminerremotecontrol --data '["LogResourceList"]' --exec '
print_config_property(analysis_context, "%s" % remote_control_data[0])'
Print the complete AminerConfig:
/usr/bin/aminerremotecontrol --exec 'print_current_config(analysis_context)'
Print a property of the running AminerConfig, change it and confirm the changed value by
printing it again:
/usr/bin/aminerremotecontrol --data '["Resources.MaxMemoryUsage", -1]' --exec '
print_config_property(analysis_context, "%s" % remote_control_data[0])' --exec
'change_config_property(analysis_context, "%s" % remote_control_data[0],
remote_control_data[1])' --exec ' print_config_property(analysis_context, "%s" %
remote_control_data[0])'
OPTIONS
with long options starting with two dashes ('-'). A summary of options is included below.
For a complete description, see the info(1) files.
--control-socket, -c socket
Specify the Unix domain remote control socket path, otherwise
/var/run/aminer-remote.socket is used. The socket is opened by aminer when
'RemoteControlSocket' feature is enabled in configuration. As the socket is of
SOCK_STREAM type, it may also be forwarded via any other stream forwarders, e.g. socat
(see UNIX-CONNECT and UNIX-LISTEN) and SSH (see LocalForward, DynamicForward). Access
control is only done by file system permissions (DAC) of the socket, so make sure not
to widen the access on error.
--exec, -e command
For each --exec option, the next argument is sent in a separate remote execution
request using additional execution data (see --data). The command is executed in a
separate execution namespace with only some variables added to the local namespace,
e.g. execution data is available as 'remote_control_data'. When setting the local
variable 'remoteControlResponse' within the executed command, the object is serialized
using json and sent back in the response.
--exec-file, -f file
For each --exec-file option, the named file is loaded and content submitted in the
very same way as if --exec parameter with content as string would have been used.
--data, -d data
This parameter defines a json string defining Python objects, that will be sent with
all subsequent --exec operations until changed again using another --data option. Take
into account, that there are size limits for the request, very large data objects may
exceed those limits. The execution context will expose the data as variable
'remote_control_data'.
--string-response, -s
When set, aminerremotecontrol will not pass the result to repr. The returned object is
just converted to a plain string via str(object) and the result is printed to avoid
escaping of quotation marks, newlines, .... WARNING: This might be insecure: without
escaping the printed data may contain terminal control sequences to exploit
vulnerabilities or misconfiguration of your terminal to execute code with privileges
of terminal or the process calling aminerremotecontrol (usually root).
Commands
change_config_property(analysis_context,property_name,value)
This method allows you to change properties from the AminerConfig at runtime. For
every property to be changed this method must be used. The method prints
"property_name changed to value successfully." if the changes were successful and an
individual message if the changes failed.
Read more about which properties can be changed in the Valid Property Names section.
change_attribute_of_registered_analysis_component(analysis_context,component_name,attribute,value)
This method allows you to change attributes from components of the AminerConfig at
runtime. For every attribute to be changed this method must be used. The method prints
"component_name.attribute changed to value successfully. " if the changes were
successful and an individual message if the changes failed. The type of the new value
must be the same like the old value of the component_name.attribute
example: aminerremotecontrol --exec
"change_attribute_of_registered_analysis_component(analysis_context, 'NewMatchPath',
'auto_include_flag', False)"
rename_registered_analysis_component(analysis_context,old_component_name,new_component_name)
Renames the component from the old_component_name to new_component_name. Therefore the
component with the old_component_name is deleted from the registered components and
registered with the new_component_name.
example: aminerremotecontrol --exec
"rename_registered_analysis_component(analysis_context,'NewMatchPath','NewMatchPathDetector')"
add_handler_to_atom_filter_and_register_analysis_component(analysis_context,atom_handler,component,component_name)
Adds the component to the atom_filter and registers it with the component_name.
example: aminerremotecontrol --exec
"add_handler_to_atom_filter_and_register_analysis_component(analysis_context,
'AtomFilter', NewMatchPathDetector(analysis_context.aminer_config,
analysis_context.atomizer_factory.atom_handler_list, auto_include_flag=True),
'NewMatchPathDet')"
print_config_property(analysis_context,property_name)
Prints the property with the property_name from the current AminerConfig.
example: aminerremotecontrol --exec
"print_config_property(analysis_context,'LogResourceList')"
print_attribute_of_registered_analysis_component(analysis_context,component_name,
attribute)
Prints the attribute of the component with the component_name.
example: aminerremotecontrol --exec
"print_attribute_of_registered_analysis_component(analysis_context,'NewMatchPath',
'auto_include_flag')"
print_current_config(analysis_context)
Prints the current AminerConfig. It is strongly recommended to use the
--string-response parameter for better readability.
example: aminerremotecontrol --exec "print_current_config(analysis_context)"
--string-response
save_current_config(analysis_context,destination_file)
Saves the current AminerConfig into destination_file. destination_file must have
write permissions by the aminerremotecontrol process or it returns an PermissionError.
example: aminerremotecontrol --exec
"save_current_config(analysis_context,'/tmp/config.py')"
persist_all()
Saves all persistence data by calling PersistenceUtil.persist_all().
example: aminerremotecontrol --exec "persist_all()"
create_backup()
Creates a backup of the current persistence directory and saves it in
{persistence_dir}/backup/{timestamp}. Use this preferably after persist_all().
example: aminerremotecontrol --exec "create_backup()"
list_backups()
Returns a list of all existing persistence backups.
example: aminerremotecontrol --exec "list_backups()"
allowlist_event_in_component(analysis_context,component_name,event_data,allowlisting_data=None)
Allowlists a path from event_data with the allowlist_event-method from the
corresponding class of the component with the component_name. Only the following
classes support allowlisting: EnhancedNewMatchPathValueComboDetector ,
MissingMatchPathValueDetector, NewMatchPathDetector and
NewMatchPathValueComboDetector. For most of the components no allowlisting_data is
needed and the event_data is a path. The NewMatchPathDetector supports a list of
multiple pathes. The MissingMatchPathValueComboDetector needs an integer as
allowlisting_data. A positive value sets the interval in seconds to the value. -1 sets
the interval to the default value of 3600. A negative value removes the
missingMatchPath. Please read the examples of this method to use the correct
parameters.
example: aminerremotecontrol --exec
"allowlist_event_in_component(analysis_context,'EnhancedNewMatchPathValueComboDetector','new/path')"
example: aminerremotecontrol --exec
"allowlist_event_in_component(analysis_context,'MissingMatchPathValueDetector','new/path',-11)"
example: aminerremotecontrol --exec
"allowlist_event_in_component(analysis_context,'NewMatchPathDetector',['new/path'])"
example: aminerremotecontrol --exec
"allowlist_event_in_component(analysis_context,'NewMatchPathValueComboDetector','new/path')"
dump_events_from_history(analysis_context,history_component_name,dump_event_id)
This method returns the string representation of a history event with the
dump_event_id. If no event with the dump_event_id could be found, the message
"FAILURE: the event with dump_event_id could not be found!" is returned.
history_component_name is the registered component of the class
VolatileLogarithmicBackoffEventHistory.
example: aminerremotecontrol --exec
"dump_events_from_history(analysis_context,'VolatileLogarithmicBackoffEventHistory',12)"
ignore_events_from_history(analysis_context,history_component_name,event_ids)
This method deletes the events with the event_ids from the history.
history_component_name is the registered component of the class
VolatileLogarithmicBackoffEventHistory. The number of deleted events is returned.
example: aminerremotecontrol --exec
"ignore_events_from_history(analysis_context,'VolatileLogarithmicBackoffEventHistory',[12,13,15])"
list_events_from_history(analysis_context,history_component_name,max_event_count=None)
This method lists max_event_count events from the history. history_component_name is
the registered component of the class VolatileLogarithmicBackoffEventHistory. If
max_event_count is None, all events from the history are returned.
example: aminerremotecontrol --exec
"list_events_from_history(analysis_context,'VolatileLogarithmicBackoffEventHistory',600)"
allowlist_events_from_history(analysis_context,history_component_name,id_spec_list,allowlisting_data=None)
This method allowlists the events with the ids in theid_spec_list from the history.
history_component_name is the registered component of the class
VolatileLogarithmicBackoffEventHistory. The allowlisting response is returned.
example: aminerremotecontrol --exec
"allowlist_events_from_history(analysis_context,'VolatileLogarithmicBackoffEventHistory',[12,13,15])"
reopen_event_handler_streams(analysis_context)
Reopen all StreamPrinterEventHandler streams for log rotation.
example: aminerremotecontrol --exec "reopen_event_handler_streams(analysis_context)"
Valid Property Names
MailAlerting.TargetAddress
Value: 'E-Mail Address'
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.TargetAddress', 'root@localhost')"
Define a target e-mail address to send alerts to. When undefined, no e-mail
notification hooks are added.
MailAlerting.FromAddress
Value: 'E-Mail Address'
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.FromAddress', 'root@localhost')"
Sender address of e-mail alerts.
MailAlerting.SubjectPrefix
Value: 'String'
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.SubjectPrefix', 'aminer Alerts:')"
Define, which text should be prepended to the standard aminer subject. Defaults to
"aminer Alerts:"
MailAlerting.EventCollectTime
Value: Seconds (Integer)
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.EventCollectTime', 10)"
Define how many seconds to wait after a first event triggered the alerting procedure
before really sending out the e-mail. In that timespan, events are collected and will
be sent all using a single e-mail. Defaults to 10 seconds.
MailAlerting.MinAlertGap
Value: Seconds (Integer)
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.MinAlertGap', 600)"
Define the minimum time between two alert e-mails in seconds to avoid spamming. All
events during this timespan are collected and sent out with the next report. Defaults
to 600 seconds.
MailAlerting.MaxAlertGap
Value: Seconds (Integer)
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.MaxAlertGap', 1000)"
Define the maximum time between two alert e-mails in seconds. When undefined this
defaults to "MailAlerting.MinAlertGap". Otherwise this will activate an exponential
backoff to reduce messages during permanent error states by increasing the alert gap
by 50% when more alert-worthy events were recorded while the previous gap time was not
yet elapsed.
MailAlerting.MaxEventsPerMessage
Value: Number of messages (Integer)
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'MailAlerting.MaxEventsPerMessage', 1000)"
Define how many events should be included in one alert mail at most. This defaults to
1000.
LogPrefix
Value: 'String'
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'LogPrefix', ' Original log line: ')"
Most analysis components implement the output_log_line-property, which is True by
default. Define a prefix to the original captured log lines. This defaults to ''.
Resources.MaxMemoryUsage
Value: 'Allowed RAM usage in Megabytes (Integer: 32-maxSystemRAM)'
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'Resources.MaxMemoryUsage', -1)"
This property limits the maximal possible RAM in MB which the aminer process can use.
Be careful at choosing the value, as a shortage of memory causes a MemoryError. This
defaults to -1, which means that there is no limit.
Core.PersistencePeriod
Value: Seconds (Integer)
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'Core.PersistencePeriod', 300)"
Use this property to change the time between persisting data in analysis components.
Defaults to 600 seconds.
Log.StatisticsLevel
Value: Level [0, 1, 2]
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'Log.StatisticsLevel', 2)"
Change the amount of data saved in statistics. Possible stat-levels are 0 for no
statistics, 1 for normal statistic level and 2 for verbose statistics. Defaults to 1.
Log.DebugLevel
Value: Level [0, 1, 2]
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'Log.DebugLevel', 2)"
Change the debug logging level. Possible debug-levels are 0 for no logging, 1 for
normal output (INFO and above), 2 for printing all debug information. Defaults to 1.
Log.StatisticsPeriod
Value: Seconds (Integer)
Example: aminerremotecontrol --exec "change_config_property(analysis_context,
'Log.StatisticsPeriod', 360)"
Change how often statistics are logged and reset. This defaults to 3600 seconds.
