Синопсис (Synopsis)

systemd-journal-gatewayd.service

systemd-journal-gatewayd.socket

/usr/lib/systemd/systemd-journal-gatewayd [OPTIONS...]

Описание (Description)

systemd-journal-gatewayd serves journal events over the network. Clients must connect using HTTP. The server listens on port 19531 by default. If --cert= is specified, the server expects HTTPS connections.

The program is started by systemd(1) and expects to receive a single socket. Use systemctl start systemd-journal-gatewayd.socket to start the service, and systemctl enable systemd-journal-gatewayd.socket to have it started on boot.

Параметры (Options)

The following options are understood:

       --cert=
           Specify the path to a file or AF_UNIX stream socket to read
           the server certificate from. The certificate must be in PEM
           format. This option switches systemd-journal-gatewayd into
           HTTPS mode and must be used together with --key=.

       --key=
           Specify the path to a file or AF_UNIX stream socket to read
           the secret server key corresponding to the certificate
           specified with --cert= from. The key must be in PEM format.

       --trust=
           Specify the path to a file or AF_UNIX stream socket to read a
           CA certificate from. The certificate must be in PEM format.

       --system, --user
           Limit served entries to entries from system services and the
           kernel, or to entries from services of current user. This has
           the same meaning as --system and --user options for
           journalctl(1). If neither is specified, all accessible
           entries are served.

       -m, --merge
           Serve entries interleaved from all available journals,
           including other machines. This has the same meaning as
           --merge option for journalctl(1).

       -D DIR, --directory=DIR
           Takes a directory path as argument. If specified,
           systemd-journal-gatewayd will serve the specified journal
           directory DIR instead of the default runtime and system
           journal paths.

       --file=GLOB
           Takes a file glob as an argument. Serve entries from the
           specified journal files matching GLOB instead of the default
           runtime and system journal paths. May be specified multiple
           times, in which case files will be suitably interleaved. This
           has the same meaning as --file= option for journalctl(1).

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

Поддерживаемые URL (Supported URLs)

The following URLs are recognized:

/browse Interactive browsing.

/entries[?option1&option2=value...] Retrieval of events in various formats.

The Accept: part of the HTTP header determines the format. Supported values are described below.

The Range: part of the HTTP header determines the range of events returned. Supported values are described below.

GET parameters can be used to modify what events are returned. Supported parameters are described below.

/machine Return a JSON structure describing the machine.

Example:

{ "machine_id" : "8cf7ed9d451ea194b77a9f118f3dc446", "boot_id" : "3d3c9efaf556496a9b04259ee35df7f7", "hostname" : "fedora", "os_pretty_name" : "Fedora 19 (Rawhide)", "virtualization" : "kvm", ...}

/fields/FIELD_NAME Return a list of values of this field present in the logs.

Принять заголовок (Accept header)

Accept: format

Recognized formats:

text/plain The default. Plaintext syslog-like output, one line per journal entry (like journalctl --output short).

application/json Entries are formatted as JSON data structures, one per line (like journalctl --output json). See Journal JSON Format[1] for more information.

text/event-stream Entries are formatted as JSON data structures, wrapped in a format suitable for Server-Sent Events[2] (like journalctl --output json-sse).

application/vnd.fdo.journal Entries are serialized into a binary (but mostly text-based) stream suitable for backups and network transfer (like journalctl --output export). See Journal Export Format[3] for more information.

Заголовок диапазона (Range header)

Range: entries=cursor[[:num_skip]:num_entries]

where cursor is a cursor string, num_skip is an integer, num_entries is an unsigned integer.

Range defaults to all available events.

Получить параметры Url (Url get parameters)

Following parameters can be used as part of the URL:

follow wait for new events (like journalctl --follow, except that the number of events returned is not limited).

discrete Test that the specified cursor refers to an entry in the journal. Returns just this entry.

boot Limit events to the current boot of the system (like journalctl -b).

KEY=match Match journal fields. See systemd.journal-fields(7).

Примеры (Examples)

Retrieve events from this boot from local journal in Journal
       Export Format[3]:

           curl --silent -H'Accept: application/vnd.fdo.journal' \
                  'http://localhost:19531/entries?boot'

       Listen for core dumps:

           curl 'http://localhost:19531/entries?follow&MESSAGE_ID=fc2e22bc6ee647b6b90729ab34a250b1'
