Clients must connect using HTTP, to port 19531 by default. The program is started by systemd1 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. 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. 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 for more information. application/event-stream Entries are formatted as JSON data structures, wrapped in a format suitable for Server-Sent Events (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 for more information. 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. 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 --this--boot). <KEY>=<match> Match journal fields. See systemd.journal-fields7. Retrieve events from this boot from local journal in Journal Export Format: 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' systemd1, journalctl1, systemd-journald.service8, systemd.journal-fields7,
