6 syncthing-event-api - Event API
7
9 Syncthing provides a simple long polling interface for exposing events
10 from the core utility towards a GUI. To receive events, see events-get.
11
13 Each event is represented by an object similar to the following:
14 {
16 "id": 2,
17 "globalID": 3,
18 "type": "DeviceConnected",
19 "time": "2014-07-13T21:04:33.687836696+02:00",
20 "data": {
21 "addr": "172.16.32.25:22000",
22 "id": "NFGKEKE-7Z6RTH7-I3PRZXS-DEJF3UJ-FRWJBFO-VBBTDND-4SGNGVZ-QUQHJAG"
23 }
24 }
25 The top level keys id, globalID, time, type and data are always
27 present, though data may be null.
28 id A unique ID for this event on the events API. It always in‐
30 creases by 1: the first event generated has id 1, the next has
31 id 2 etc. If this increases by more than 1, then one or more
32 events have been skipped by the events API.
33 globalID
35 A global ID for this event, across the events API, the audit
36 log, and any other sources. It may increase by more than 1, but
37 it will always be greater than or equal to the id.
38 time The time the event was generated.
40 type Indicates the type of (i.e. reason for) the event and is one of
42 the event types below.
43 data An object containing optional extra information; the exact
45 structure is determined by the event type.
46
48 ConfigSaved
49 Emitted after the config has been saved by the user or by Syncthing it‐
50 self.
51 {
53 "id": 50,
54 "globalID": 50,
55 "type": "ConfigSaved",
56 "time": "2014-12-13T00:09:13.5166486Z",

59 "Options": {"..."},
60 "GUI": {"..."},
61 "Devices": [{"..."}],
62 "Folders": [{"..."}]
63 }
64 }
65 DeviceConnected
67 Generated each time a connection to a device has been established.
68 {
70 "id": 2,
71 "globalID": 2,
72 "type": "DeviceConnected",
73 "time": "2014-07-13T21:04:33.687836696+02:00",
74 "data": {
75 "addr": "172.16.32.25:22000",
76 "id": "NFGKEKE-7Z6RTH7-I3PRZXS-DEJF3UJ-FRWJBFO-VBBTDND-4SGNGVZ-QUQHJAG",
77 "deviceName": "Laptop",
78 "clientName": "syncthing",
79 "clientVersion": "v0.13.4",
80 "type": "TCP (Client)"
81 }
82 }
83 DeviceDisconnected
85 Generated each time a connection to a device has been terminated.
86 {
88 "id": 48,
89 "globalID": 48,
90 "type": "DeviceDisconnected",
91 "time": "2014-07-13T21:18:52.859929215+02:00",
92 "data": {
93 "error": "unexpected EOF",
94 "id": "NFGKEKE-7Z6RTH7-I3PRZXS-DEJF3UJ-FRWJBFO-VBBTDND-4SGNGVZ-QUQHJAG"
95 }
96 }
97 NOTE:
99 The error key contains the cause for disconnection, which might not
100 necessarily be an error as such. Specifically, “EOF” and “unexpected
101 EOF” both signify TCP connection termination, either due to the
102 other device restarting or going offline or due to a network change.
103 DeviceDiscovered
105 Emitted when a new device is discovered using local discovery.
106 {
108 "id": 13,
109 "globalID": 13,
110 "type": "DeviceDiscovered",
111 "time": "2014-07-17T13:28:05.043465207+02:00",

130 }
131 }
132 DeviceRejected
134 Deprecated since version v1.13.0: This event is still emitted for com‐
135 patibility, but deprecated. Use the replacement pending-de‐
136 vices-changed event instead.
137 Emitted when there is a connection from a device we are not configured
140 to talk to.
141 {
143 "id": 24,

164 }
165 }
166 DownloadProgress
168 Emitted during file downloads for each folder for each file. By default
169 only a single file in a folder is handled at the same time, but custom
170 configuration can cause multiple files to be shown.
171 {

224 • total - total number of blocks in the file
226 • pulling - number of blocks currently being downloaded
228 • copiedFromOrigin - number of blocks copied from the file we are about
230 to replace
231 • reused - number of blocks reused from a previous temporary file
233 • copiedFromElsewhere - number of blocks copied from other files or po‐
235 tentially other folders
236 • pulled - number of blocks actually downloaded so far
238 • bytesTotal - approximate total file size
240 • bytesDone - approximate number of bytes already handled (already
242 reused, copied or pulled)
243 Where block size is 128KB.
245 Files/folders appearing in the event data imply that the download has
247 been started for that file/folder, where disappearing implies that the
248 downloads have been finished or failed for that file/folder. There is
249 always a last event emitted with no data, which implies all downloads
250 have finished/failed.
251 FolderCompletion
253 The FolderCompletion event is emitted when the local or remote contents
254 for a folder changes. It contains the completion percentage for a given
255 remote device and is emitted once per currently connected remote de‐
256 vice.
257 {

266 "folder": "default"
267 }
268 }
269 FolderErrors
271 The FolderErrors event is emitted when a folder cannot be successfully
272 synchronized. The event contains the ID of the affected folder and a
273 list of errors for files or directories therein. This list of errors is
274 obsolete once the folder changes state to syncing - if errors remain
275 after the next synchronization attempt, a new FolderErrors event is
276 emitted.

279 "id": 132,

319 Folder Scan Progress
321 Emitted in regular intervals (folder setting ProgressIntervalS, 2s by
322 default) during scans giving the amount of bytes already scanned and to
323 be scanned in total , as well as the current scanning rates in bytes
324 per second.

338 FolderSummary
340 The FolderSummary event is emitted when folder contents have changed
341 locally. This can be used to calculate the current local completion
342 state.

484 Generated upon scan whenever the local disk has discovered an updated

564 PendingFoldersChanged
566 New in version 1.14.0.

570 vice, but not shared to them) or removed (folder ignored or added or no
