json
The
json parser plugin parses JSON logs. One JSON map per line.type | default | available | version |
enum | oj | oj, yajl, json | 0.14.0 |
Sets the JSON parser. If you have a problem with the configured parser, check the other available parser types.
NOTE: If you want to enable
json_parser oj by default, The oj gem must be installed separately. This is because oj gem is not required from fluentd by default. If oj gem is not installed, yajl is used as a fallback.Here is a simple comparison:
oj: Faster json parseryajl: Mainly for stream parsingjson: Standard bundled library
type | default | version |
integer | 8192 | 1.0.0 |
Set the buffer size that Yajl will use when parsing streaming input.
json parser changes the default value of time_type to float. If you want to parse string field, set time_type and time_format like this:# conf
@type json
time_type string
time_format %d/%b/%Y:%H:%M:%S %z
# record example
{"key":"value","time":"28/Feb/2013:12:00:00 +0900"}
This incoming event:
{"time":1362020400,"host":"192.168.0.1","size":777,"method":"PUT"}
is parsed as:
time:
1362020400 (2013-02-28 12:00:00 +0900)
record:
{
"host" : "192.168.0.1",
"size" : 777,
"method": "PUT",
}
