.SH DESCRIPTION
.sp
Syncthing provides a simple long polling interface for exposing events from the
core utility towards a GUI. To receive events, see events\-get\&.
.SH EVENT STRUCTURE
.sp
Each event is represented by an object similar to the following:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
{
    "id": 2,
    "globalID": 3,
    "type": "DeviceConnected",
    "time": "2014\-07\-13T21:04:33.687836696+02:00",
    "data": {
        "addr": "172.16.32.25:22000",

.sp
The top level keys \fBid\fP, \fBglobalID\fP, \fBtime\fP, \fBtype\fP and \fBdata\fP are always present,
though \fBdata\fP may be \fBnull\fP\&.
.INDENT 0.0
.TP
.B id
A unique ID for this event on the events API. It always increases by 1: the first
event generated has id \fB1\fP, the next has id \fB2\fP etc. If this increases by
more than 1, then one or more events have been skipped by the events API.
.TP
.B globalID
A global ID for this event, across the events API, the audit log, and any other
sources. It may increase by more than 1, but it will always be greater
than or equal to the id.
.TP
.B time
The time the event was generated.
.TP
.B type
Indicates the type of (i.e. reason for) the event and is one of the event
types below.
.TP
.B data
An object containing optional extra information; the exact structure is
determined by the event type.

necessarily be an error as such. Specifically, “EOF” and “unexpected
EOF” both signify TCP connection termination, either due to the other
device restarting or going offline or due to a network change.

Files/folders appearing in the event data imply that the download has
been started for that file/folder, where disappearing implies that the
downloads have been finished or failed for that file/folder. There is
always a last event emitted with no data, which implies all downloads
have finished/failed.
.SS FolderCompletion
.sp
The \fBFolderCompletion\fP event is emitted when the local or remote
contents for a folder changes. It contains the completion percentage for
a given remote device and is emitted once per currently connected remote
device.
