Note:
Thedepth
query parameter and the match_property-name=value
query parameter are not supported.
Example Request:
GET /api/log/v1/logs HTTP/1.1 Authorization: Basic Tm8gcGVla2luZyE= Host: zfs-storage.example.com:215 Accept: application/json
Example Result:
HTTP/1.1 200 OK X-Zfssa-Appliance-Api: 1.0 Content-Type: application/json Content-Length: 532 X-Zfssa-Api: 1.0 { "logs": [ { "href": "/api/log/v1/logs/fault", "name": "faults", "size": 16, "updated": "20130614T22:51:48" }, { "href": "/api/log/v1/logs/audit", "name": "audits", "size": 460149, "updated": "20130730T22:10:41" }, { "href": "/api/log/v1/logs/alert", "name": "alerts", "size": 13054, "updated": "20130728T00:06:10" }, { "href": "/api/log/v1/logs/phone-home", "name": "phone-home", "size": 249, "updated": "20130730T03:22:35" }, { "href": "/api/log/v1/logs/system", "name": "system", "size": 344, "updated": "20130724T03:21:55" } ] }
Get Log Entries
Log entries can be returned from the specified appliance log. Each log entry returns the date/time of the entry along with log specific content properties.
Note:
Depending on the number of logs, older log entries might not be available due to memory constraints. This same limit occurs in the BUI and CLI. To obtain all system logs, use thecollect
function described in Manage Logs Commands.
Parameter | Description |
---|---|
|
Start returning logs from the given index/time |
|
Limit number of log entries returned |
The start index defaults to the value of 0, which returns the first log that was generated. Negative values and values greater than or equal to the log size are not allowed. The start index can also be a time string; for example, 20130724T03:21:55.
Note:
REST only accepts UTC time. Time values that are older than one month from the current time are not accepted. Retrieval of older logs must use an index number for the start value. The limit value limits the number of logs returned for a given request. No more than the given limit value is returned.Example Request:
GET /api/log/v1/logs/audit?limit=4&start=1000 HTTP/1.1 Authorization: Basic Tm8gcGVla2luZyE= Host: zfs-storage.example.com:215 Accept: application/json

Download Logs
The download logs command returns a gzipped tar file containing all of the system logs. The file disposition name is set to logs.tar.gz
. Because the data is created and streamed in real time, it is not possible to resume a download.
Download Log
If only one log type is desired to be downloaded, its name can be appended to the collect
resource as shown in the table. The text of the log is streamed back to the client. If gzip
compression is requested, the text stream is compressed with gzip
. Other compression types are not supported and are ignored.
