tinysyslog's Issues

Regex filter not being loaded correctly?

The grok pattern seems to load:

# docker run --rm --name tinysyslog -p 2514:5140/udp admiralobvious/tinysyslog --log-level debug --filter-grok-pattern test --filter grok
time="2020-01-31T00:34:39Z" level=info msg="tinysyslog starting"
time="2020-01-31T00:34:39Z" level=debug msg="Using mutator type 'text'"
time="2020-01-31T00:34:39Z" level=debug msg="Using filter type 'grok' with pattern 'test'"
time="2020-01-31T00:34:39Z" level=debug msg="Adding sink type 'console'"
time="2020-01-31T00:34:39Z" level=info msg="tinysyslog listening on 0.0.0.0:5140"

But it doesn't look like the regex filter does:

# docker run --rm --name tinysyslog -p 2514:5140/udp admiralobvious/tinysyslog --log-level debug --filter-regex test --filter regex
time="2020-01-31T00:36:52Z" level=info msg="tinysyslog starting"
time="2020-01-31T00:36:52Z" level=debug msg="Using mutator type 'text'"
time="2020-01-31T00:36:52Z" level=debug msg="Using filter type 'regex' with filter ''"
time="2020-01-31T00:36:52Z" level=debug msg="Adding sink type 'console'"
time="2020-01-31T00:36:52Z" level=info msg="tinysyslog listening on 0.0.0.0:5140"

I'm not super sure, but it looks like maybe this line needs changed from filter-regex-filter to filter-regex?

Mikrotik logs display as blank

Hi,

Syslogs from Mikrotik routers show like this:

tinysyslog  | time="2024-01-21T20:37:53Z" level=info msg="tinysyslog listening on 0.0.0.0:5140"
tinysyslog  | Jan  1 00:00:00  []:

tinysyslog  | Jan  1 00:00:00  []: 
tinysyslog  | Jan  1 00:00:00  []:

A tcpdump of the UDP packet shows that it does contain the log message.
