Grok Parse Failure on Custom Log Format and regex in logstash -

-

i have custom log format ,i new trying figure out how works . not getting parsed in logstash .can identify issue.

logformat follows 

{u'key_id': u'1sdfasdfvaa/sd456dfdffas/zasder==', u'type': u'audio'}, {u'key_id': u'iu-dsfaz+ka/q1sdfq==', u'type': u'hd'}], u'model': u'level1', u'license_metadata': {u'license_type': u'streaming set', u'request_type': u'new', u'content_id': u'aaaa='}, u'message_type': u'license', u'cert_serial_number': u'aaaasssseerrttyuuiioooasa='}

i need parsed in logstash , store in elasticsearch

the problem none of existing grok pattern taking care of , unaware of regex custom config

alain's comment may useful you, if log is, in fact, coming in json may want @ json filter automajically parse json message elastic friendly format or using json codec in input.

if want stick grok, great resource building custom grok patterns grok constructor.
