fluentd filter regex pattern gives an invalid strptime format error - regex

Question

I am trying to use the regex filter to parse my log
My regex expression and sample string are as follows
Regex:
/^(?<logtime>[^\|]*)\S +(?<cpu-usr>\S+) +(?<cpu-sys>\S+) +(?<cpu-idl>\S+) +(?<cpu-wai>\S+) +(?<cpu-hiq>\S+) +(?<cpu-siq>[^|]+)\S +(?<mem-used>\S+) +(?<mem-buff>\S+) +(?<mem-cach>\S+) +(?<mem-free>\S+)/
Sample string:
07-07 17:18:12| 0 0 100 0 0 0| 197M 48.9M 182M 546M
So I have written the following filter into my fluent.conf file
#filter dstat log into fields.
#----system---- ----total-cpu-usage---- ------memory-usage-----
# date/time |usr sys idl wai hiq siq| used buff cach free
<filter input.dstat>
#type parser
format /^(?<logtime>[^\|]*)\S +(?<cpu-usr>\S+) +(?<cpu-sys>\S+) +(?<cpu-idl>\S+) +(?<cpu-wai>\S+) +(?<cpu-hiq>\S+) +(?<cpu-siq>[^|]+)\S +(?<mem-used>\S+) +(?<mem-buff>\S+) +(?<mem-cach>\S+) +(?<mem-free>\S+)/
time_format %d-%m %H:%M:%S
time_key logtime
keep_time_key true
key_name log
</filter>
However, I get the following error for this filter.
fluentd_1 | 2017-07-07 05:42:36 +0000 [warn]: invalid time format: value = 07-0, error_class = ArgumentError, error = invalid strptime format - `%d-%m %H:%M:%S'
I have already checked the regex and time format using http://fluentular.herokuapp.com/ and it seems to be ok according to that. How do I proceed with this? My current assumption is that the error is due to %Y or year being missing from the time format. However my log does not contain the year information.

The problem was that I used '-' in the names instead of '_'
After replacing them, it works fine.
