After 3b16e9f419, even the libraries are
documented in the man page, it is useful to mention which libraries are
checked in the command output.
Of course, the dependencies are kind of implementation detail, and may
be changed in the future version, but that's especially why I think
showing the library deps in the output is useful.
systemd-analyze is a debugging tool, and already shows many internal
states. I think there is nothing to prevent from showing the deps.
Prompted by #34477.

<title>Description</title>
|
|
|
|
<para><command>systemd-analyze</command> may be used to determine
|
|
system boot-up performance statistics and retrieve other state and
|
|
tracing information from the system and service manager, and to
|
|
verify the correctness of unit files. It is also used to access
|
|
special functions useful for advanced system manager debugging.</para>
|
|
|
|
<para>If no command is passed, <command>systemd-analyze
|
|
time</command> is implied.</para>
|

<refsect2>
|
|
<title><command>systemd-analyze time</command></title>
|
|
|
|
<para>This command prints the time spent in the kernel before userspace has been reached, the time
|
|
spent in the initrd before normal system userspace has been reached, and the time normal system
|
|
userspace took to initialize. Note that these measurements simply measure the time passed up to the
|
|
point where all system services have been spawned, but not necessarily until they fully finished
|
|
initialization or the disk is idle.</para>
|
|
|
|
<example>
|
|
<title><command>Show how long the boot took</command></title>
|
|
|
|
<programlisting># in a container
|
|

|

|
|
|
|
# on a real machine
|
|
$ systemd-analyze time
|
|
Startup finished in 2.584s (kernel) + 19.176s (initrd) + 47.847s (userspace) = 1min 9.608s
|
|

|
<title><command>systemd-analyze blame</command></title>
|
|
|
|
<para>This command prints a list of all running units, ordered by the time they took to initialize.
|
|
This information may be used to optimize boot-up times. Note that the output might be misleading as the
|
|
initialization of one service might be slow simply because it waits for the initialization of another
|
|
service to complete. Also note: <command>systemd-analyze blame</command> doesn't display results for
|
|
services with <varname>Type=simple</varname>, because systemd considers such services to be started
|
|
immediately, hence no measurement of the initialization delays can be done. Also note that this command
|
|
only shows the time units took for starting up, it does not show how long unit jobs spent in the
|
|
execution queue. In particular it shows the time units spent in <literal>activating</literal> state,
|
|
which is not defined for units such as device units that transition directly from
|
|
<literal>inactive</literal> to <literal>active</literal>. This command hence gives an impression of the
|
|
performance of program code, but cannot accurately reflect latency introduced by waiting for
|
|
hardware and similar events.</para>
|
|
|
|
<example>
|
|
<title><command>Show which units took the most time during boot</command></title>
|
|
|
|
<programlisting>$ systemd-analyze blame

<title><command>systemd-analyze critical-chain <optional><replaceable>UNIT</replaceable>...</optional></command></title>
|
|
|
|
<para>This command prints a tree of the time-critical chain of units (for each of the specified
|
|
<replaceable>UNIT</replaceable>s or for the default target otherwise). The time after the unit is
|
|
active or started is printed after the "@" character. The time the unit takes to start is printed after
|
|
the "+" character. Note that the output might be misleading as the initialization of services might
|
|
depend on socket activation and because of the parallel execution of units. Also, similarly to the
|
|
<command>blame</command> command, this only takes into account the time units spent in
|
|
<literal>activating</literal> state, and hence does not cover units that never went through an
|
|
<literal>activating</literal> state (such as device units that transition directly from
|
|
<literal>inactive</literal> to <literal>active</literal>). Moreover it does not show information on
|
|
jobs (and in particular not jobs that timed out).</para>

<citerefentry project='man-pages'><refentrytitle>malloc_info</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
|

<filename>org.freedesktop.systemd1</filename> (the system or user service manager). The output format

|

<para>This command prints either an SVG graphic, detailing which system services have been started at what
|
|
time, highlighting the time they spent on initialization, or the raw time data in JSON or table format.</para>

<example>

</programlisting>
|

</example>
|
|
|
|
<para>Note that this plot is based on the most recent per-unit timing data of loaded units. This means
|
|
that if a unit gets started, then stopped and then started again the information shown will cover the
|
|
most recent start cycle, not the first one. Thus it's recommended to consult this information only
|
|
shortly after boot, so that this distinction doesn't matter. Moreover, units that are not referenced by
|
|
any other unit through a dependency might be unloaded by the service manager once they terminate (and
|
|
did not fail). Such units will not show up in the plot.</para>

|
generate a graphical dependency tree. Unless <option>--order</option> or <option>--require</option> is

|
passed, the generated graph will show both ordering and requirement dependencies. Optional pattern
|
|
globbing style specifications (e.g. <filename>*.target</filename>) may be given at the end. A unit
|
|
dependency is included in the graph if any of these patterns match either the origin or destination
|

|
|
|
|
<para>This command analyzes the security and sandboxing settings of one or more specified service
|
|
units. If at least one unit name is specified the security settings of the specified service units are
|
|
inspected and a detailed analysis is shown. If no unit name is specified, all currently loaded,
|
|
long-running service units are inspected and a terse table with results shown. The command checks for
|
|
various security-related service settings, assigning each a numeric "exposure level" value, depending
|
|
on how important a setting is. It then calculates an overall exposure level for the whole unit, which
|
|
is an estimation in the range 0.0…10.0 indicating how exposed a service is security-wise. High exposure
|
|
levels indicate very little applied sandboxing. Low exposure levels indicate tight sandboxing and
|
|
strongest security restrictions. Note that this only analyzes the per-service security features systemd
|
|
itself implements. This means that any additional security mechanisms applied by the service code
|
|
itself are not accounted for. The exposure level determined this way should not be misunderstood: a
|
|
high exposure level neither means that there is no effective sandboxing applied by the service code
|
|
itself, nor that the service is actually vulnerable to remote or local attacks. High exposure levels do
|
|
indicate however that most likely the service might benefit from additional settings applied to
|
|
them.</para>
|
|
|
|
<para>Please note that many of the security and sandboxing settings individually can be circumvented —
|
|
unless combined with others. For example, if a service retains the privilege to establish or undo mount
|
|
points many of the sandboxing options can be undone by the service code itself. Due to that is
|
|
essential that each service uses the most comprehensive and strict sandboxing and security settings
|
|
possible. The tool will take into account some of these combinations and relationships between the
|
|
settings, but not all. Also note that the security and sandboxing settings analyzed here only apply to
|
|
the operations executed by the service code itself. If a service has access to an IPC system (such as
|
|
D-Bus) it might request operations from other services that are not subject to the same
|
|
restrictions. Any comprehensive security and sandboxing analysis is hence incomplete if the IPC access
|
|
policy is not validated too.</para>

<para>Reports whether the system is equipped with a usable TPM2 device. If a TPM2 device has been

discovered, is supported, and is being used by firmware, by the OS kernel drivers and by userspace

(i.e. systemd) this prints <literal>yes</literal> and exits with exit status zero. If no such device is

discovered/supported/used, prints <literal>no</literal>. Otherwise prints

<literal>partial</literal>. In either of these two cases exits with non-zero exit status. It also shows
|

five lines indicating separately whether firmware, drivers, the system, the kernel and libraries
|
|
discovered/support/use TPM2. Currently, required libraries are <filename>libtss2-esys.so.0</filename>,

<filename>libtss2-rc.so.0</filename>, and <filename>libtss2-mu.so.0</filename>. The requirement may be

<title>JSON Policy</title>
|
|
|
|
<para>The JSON file passed as a path parameter to <option>--security-policy=</option> has a top-level
|
|
JSON object, with keys being the assessment test identifiers mentioned above. The values in the file
|
|
should be JSON objects with one or more of the following fields: <option>description_na</option>
|
|
(string), <option>description_good</option> (string), <option>description_bad</option> (string),
|
|
<option>weight</option> (unsigned integer), and <option>range</option> (unsigned integer). If any of
|
|
these fields corresponding to a specific id of the unit file is missing from the JSON object, the
|
|
default built-in field value corresponding to that same id is used for security analysis as default.
|
|
The weight and range fields are used in determining the overall exposure level of the unit files: the
|
|
value of each setting is assigned a badness score, which is multiplied by the policy weight and divided
|
|
by the policy range to determine the overall exposure that the setting implies. The computed badness is
|
|
summed across all settings in the unit file, normalized to the 1…100 range, and used to determine the
|
|
overall exposure level of the unit. By allowing users to manipulate these fields, the 'security' verb
|
|
gives them the option to decide for themself which ids are more important and hence should have a
|
|
greater effect on the exposure level. A weight of <literal>0</literal> means the setting will not be
|
|
checked.</para>
