    <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
$ systemd-analyze time
Startup finished in 296ms (userspace)
multi-user.target reached after 275ms in userspace

# on a real machine
$ systemd-analyze time
Startup finished in 2.584s (kernel) + 19.176s (initrd) + 47.847s (userspace) = 1min 9.608s
multi-user.target reached after 47.820s in userspace
</programlisting>
      </example>
    </refsect2>

    <refsect2>
      <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> does not 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
         32.875s pmlogger.service
         20.905s systemd-networkd-wait-online.service
         13.299s dev-vda1.device
         ...
            23ms sysroot.mount
            11ms initrd-udevadm-cleanup-db.service
             3ms sys-kernel-config.mount
</programlisting>
      </example>
    </refsect2>

    <refsect2>
      <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>

      <example>
        <title><command>systemd-analyze critical-chain</command></title>

      <programlisting>$ systemd-analyze critical-chain

      <title><command>systemd-analyze dump [<replaceable>pattern</replaceable>…]</command></title>

      <para>Without any parameter, this command outputs a (usually very long) human-readable serialization of
      the complete service manager state. Optional glob pattern may be specified, causing the output to be
      limited to units whose names match one of the patterns. The output format is subject to change without
      notice and should not be parsed by applications. This command is rate limited for unprivileged users.</para>

      <example>
        <title>Show the internal state of user manager</title>

        <programlisting>$ systemd-analyze --user dump

      <title><command>systemd-analyze malloc [<replaceable>D-Bus service</replaceable>…]</command></title>

      <para>This command can be used to request the output of the internal memory state (as returned by
      <citerefentry project='man-pages'><refentrytitle>malloc_info</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
      of a D-Bus service. If no service is specified, the query will be sent to
      <filename>org.freedesktop.systemd1</filename> (the system or user service manager). The output format
      is not guaranteed to be stable and should not be parsed by applications.</para>

      <para>The service must implement the <filename>org.freedesktop.MemoryAllocation1</filename> interface.
      In the systemd suite, it is currently only implemented by the manager.</para>
    </refsect2>

    <refsect2>
      <title><command>systemd-analyze plot</command></title>

      <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>
        <title><command>Plot a bootchart</command></title>

        <programlisting>$ systemd-analyze plot >bootup.svg
$ eog bootup.svg&amp;
</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 is recommended to consult this information only
      shortly after boot, so that this distinction does not 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>
    </refsect2>

    <refsect2>
      <title><command>systemd-analyze dot [<replaceable>pattern</replaceable>...]</command></title>

      <para>This command generates textual dependency graph description in dot format for further processing
      with the GraphViz
      <citerefentry project='die-net'><refentrytitle>dot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
      tool. Use a command line like <command>systemd-analyze dot | dot -Tsvg >systemd.svg</command> to
      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
      node.</para>

      <example>
        <title>Plot all dependencies of any unit whose name starts with <literal>avahi-daemon</literal>
        </title>

        <programlisting>$ systemd-analyze dot 'avahi-daemon.*' | dot -Tsvg >avahi.svg
$ eog avahi.svg</programlisting>
      </example>

      <example>
        <title>Plot the dependencies between all known target units</title>

        <programlisting>$ systemd-analyze dot --to-pattern='*.target' --from-pattern='*.target' \
      | dot -Tsvg >targets.svg
$ eog targets.svg</programlisting>
      </example>
    </refsect2>

    <refsect2>
      <title><command>systemd-analyze unit-paths</command></title>

      <para>This command outputs a list of all directories from which unit files, <filename>.d</filename>
      overrides, and <filename>.wants</filename>, <filename>.requires</filename> symlinks may be
      loaded. Combine with <option>--user</option> to retrieve the list for the user manager instance, and
      <option>--global</option> for the global configuration of user manager instances.</para>

      <example>
        <title><command>Show all paths for generated units</command></title>

        <programlisting>$ systemd-analyze unit-paths | grep '^/run'
/run/systemd/system.control
/run/systemd/transient
/run/systemd/generator.early
/run/systemd/system
/run/systemd/system.attached
/run/systemd/generator
/run/systemd/generator.late
</programlisting>
      </example>

      <para>Note that this verb prints the list that is compiled into <command>systemd-analyze</command>
      itself, and does not communicate with the running manager. Use
      <programlisting>systemctl [--user] [--global] show -p UnitPath --value</programlisting>
      to retrieve the actual list that the manager uses, with any empty directories omitted.</para>
    </refsect2>

    <refsect2>
      <title><command>systemd-analyze exit-status <optional><replaceable>STATUS</replaceable>...</optional></command></title>

      <para>This command prints a list of exit statuses along with their "class", i.e. the source of the
      definition (one of <literal>libc</literal>, <literal>systemd</literal>, <literal>LSB</literal>, or
      <literal>BSD</literal>), see the Process Exit Codes section in
      <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
      If no additional arguments are specified, all known statuses are shown. Otherwise, only the
      definitions for the specified codes are shown.</para>

      <example>
        <title><command>Show some example exit status names</command></title>

        <programlisting>$ systemd-analyze exit-status 0 1 {63..65}

      <title><command>systemd-analyze security <optional><replaceable>UNIT</replaceable>...</optional></command></title>

      <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
      changed in the future release.</para>

      <para>Note, this checks for TPM 2.0 devices only, and does not consider TPM 1.2 at all.</para>

        units files present in the directory containing the specified unit will be used in preference to the
        other paths. If a template unit without an instance name is specified (e.g.

    <title>Exit status</title>

    <para>For most verbs, <constant>0</constant> is returned on success, and a non-zero failure code
    otherwise.</para>

    <para>For the verb <command>compare-versions</command>, in the two-argument form,
    <constant>12</constant>, <constant>0</constant>, or <constant>11</constant> are returned if the second
    version string is respectively larger than, equal to, or smaller than the first. In the three-argument
    form, <constant>0</constant> or <constant>1</constant> are returned when the condition is respectively
    true or false.</para>

    <para>For the verb <command>has-tpm2</command>, <constant>0</constant> is returned if a TPM2 device is
    discovered, supported, and used by firmware, driver, and userspace (i.e. <command>systemd</command>).
    Otherwise, the OR combination of the value <constant>1</constant> (in case firmware support is missing),
    <constant>2</constant> (in case driver support is missing), and <constant>4</constant> (in case userspace
    support is missing). If no TPM2 support is available at all, value <constant>7</constant> is hence
    returned.</para>

    <example>
      <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>
