Example for LTSV

This incoming event:
time:2013/02/28 12:00:00\thost:192.168.0.1\treq_id:111\tuser:-
is parsed as:
time:
1362020400 (2013/02/28/ 12:00:00)
record:
{
"host" : "192.168.0.1",
"req_id" : "111",
"user" : "-"
}
If you set null_value_pattern '-' in the configuration, user field becomes nil instead of "-".

Example with delimiter_pattern

With this configuration:
<parse>
@type ltsv
delimiter_pattern /\s+/
label_delimiter =
</parse>
This incoming event:
timestamp=1362020400 host=192.168.0.1 req_id=111 user=-
is parsed as:
record:
{
"timestamp": "1362020400",
"host" : "192.168.0.1",
"req_id" : "111",
"user" : "-"
}
