The syntax %{[fieldname]}, Source The field containing the IP address, this is a required setting, Target By defining a target in the geoip configuration option, You can specify the field into which Logstash should store the geoip data, Pattern This required setting is a regular expression that matches a pattern that indicates that the field is part of an event consisting of multiple lines of log data, What This can use one of two options (previous or next) to provide the context for which (multiline) event the current message belongs, Match You can specify an array of a field name, followed by a date-format pattern. the ssl_certificate and ssl_key options. The value must be one of the following: 1.1 for TLS 1.1, 1.2 for TLS 1.2, 1.3 for TLS 1.3. This ensures that events always start with a ^%{LOGLEVEL} matching line and is what you want. That is, TLSv1.1 needs to be removed from the list. Proper event ordering needs to be followed as the processing of multiline events is a very critical and complex job. The what must be previous or next and indicates the relation patterns. Also, if no Codec is This tells logstash to join any line that does not match ^% {LOGLEVEL} to the previous line. codec => multiline { pattern => "^% {LOGLEVEL}" negate => "true" what => "previous" } instead. We like them so much that we regularly, Unlike your typical single-line log events, stack traces have multiple lines and they arent always perfectly uniform. Doing so may result in the mixing of streams and corrupted event data. tips for handling stack traces with rsyslog and syslog-ng are coming. If you are using a Logstash input plugin that supports multiple hosts, such as the beats input plugin, you should not use the multiline codec to handle multiline events.
