Thanks for your help. Solved it with this grok config which is pretty similar to your suggestion. grok { patterns_dir => "/path/to/elk-stack/logstash-1.4.2/bin/custom_patterns" match => [ "message", "\"%{GREEDYDATA:domain}\" - %{IP:client_ip} \[%{GREEDYDATA:log_timestamp}\] \"%{WORD:method}\" \"%{GREEDYDATA:request_uri}\" - \"%{GREEDYDATA:query_string}\" - \"%{GREEDYDATA:protocol}\" - %{NUMBER:http_statuscode} %{NUMBER:bytes} \"%{GREEDYDATA:user_agent}\" %{NUMBER:seconds} %{NUMBER:milliseconds} \"%{GREEDYDATA:server_node}\""] match...
Yes, this is expected. I don't think there's a way to produce nested fields with grok. I suspect you'll have to use the mutate filter to move them into place. mutate { rename => { "date" => "[drupal][date]" "instigator" => "[drupal][instigator]" ... } } If you have a lot of...

Your problem is that the regex for WORD matches a number. The easiest thing to do would be to protect the grok's so that they don't run for IP addresses: if [src] !~ /\d+\.\d+\.\d+\.\d+/ { grok { match => { "src" => "%{WORD:src}" } overwrite => ["src"] } } And...
Logstash can't operate on more than one .conf simultaneously, or create some sort of workflow of configuration files, its just not supported/implemented that way. The .conf file tells logstash what inputs to read, what filters to apply, and how to output the events. You'll have to put everything in one...

The grok filter is used to extract fields from messages. It doesn't do any filtering. You should use a conditional and the drop filter: filter { if [message] !~ /Server start up in/ { drop { } } } Or: filter { if "Server start up in" not in [message]...

It's quite possible that Logstash is doing the right thing here (your configuration looks correct), but how Elasticsearch maps the fields is another matter. If a field in an Elasticsearch document at some point has been dynamically mapped as a string, subsequent documents added to the same index will also...
you can make the brackets optional by doing something like [\[]* and [\]]* %{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}[\[]*%{POSINT:syslog_pid}[\]]*: %{GREEDYDATA:syslog_message} ...

The _grokparsefailure is not add by your own filter grok. When you use syslog input, the syslog format must be follow RFC3164, as mentioned in here. Generally , Syslog input will parse the log and add corresponding field like log severity. So, there is a grok action in it. However,...

You need to use GROK filter to extract the time value and then use DATE filter parse the value into @timestamp For example: input { stdin { codec => multiline { pattern => "(^%{TIMESTAMP_ISO8601}) | (^.+Exception+) | (^.+Error+)" negate => true what => "previous" } } } filter { grok...
If you want to unconditionally drop a field, just add a remove_field => ['port'] to you grok block. If you want to conditionally remove something, you can use either a ruby filter to check what is in the field before removing it, or use an if around a mutate {...

So one part that was annoying me was the geoip filter when using the COMBINEDAPACHELOG pattern to parse the line: 192.168.1.5 portal.mycompany.com - - [15/Mar/2015:04:15:02 -0400] "GET /index.php/account/process_upload_file?upload_file=T702135.0315.txt HTTP/1.0" 200 9 "-" "Wget/1.11.4 Red Hat modified" It would get the ip of portal.mycompany.com and use that to determine the location....
Conditionals go outside the filters, so something like: if [field] == "value" { grok { ... } ] would be correct. In your case, do the first grok, then test to run the second, i.e.: grok { match => [ "message", "%{NUMBER:engcode1} %{DATESTAMP_12H:timestamp} %{NUMBER:engcode2} %{NUMBER:engcode3} %{NUMBER:engcode4} %{NUMBER:ppid} %{NUMBER:pid} %{NUMBER:engcode5} %{WORD:processhost}...
If your grok{} fails to match a one of the patterns that you've provided, it will set a tag called "_grokparsefailure". You can search for this: tags:_grokparsefailure If you have multiple grok{} filters, it's recommended to use the tag_on_failure parameter to set a different tag for each grok, so you...

First, you have to parse out your json data by grok filter. Then, use json filter to parse all the hashmap value. With this config I can parse your log and create all the field:value. Hope this can help you. input { stdin{ } } filter { grok { match...
Since your grok pattern contains double quotes you have to either escape the double quotes inside the expression by preceding them with a backslash, or use single quotes as the pattern string delimiter. Example 1: grok { match => ["message", "<log4j:event logger=\"%{DATA:emitter}\" ..." ] } Example 2: grok { match...

What about something like this, to replace the last element of your grok filter? \"%{WORD:verb} %{NOTSPACE:request} HTTP/%{NUMBER:httpversion}\" I've never actually administered logstash before, but I pieced this together by looking at the source code for the built-in filters, some of which are evidently built on top of other built-in filters....

I would avoid using transaction commits in test code. The test framework is specifically designed to roll back the transactions at the end of each test. Your setUp override goes against this.

Don't get hung up on the fact that the logfile happens to have a fixed-width format. It doesn't really help here since. Parse the file like it's any old logfile using relevant grok patterns. This works for the input you provided: (?<timestamp>%{DATE_US} %{TIME} (?:AM|PM))\s+%{NUMBER}\s+%{WORD:dns_type}\s+ %{BASE16NUM}\s+%{WORD:dns_protocol}\s+%{WORD:dns_direction}\s+%{IP:dns_ip}\s+ %{BASE16NUM}\s+%{WORD:dns_query_type}\s+\[%{BASE16NUM}\s+%{WORD}\s+ %{WORD:dns_result}\]\s+%{WORD:dns_record}\s+%{GREEDYDATA:dns_domain} That said, since...
TIMESTAMP_ISO8601 matches: %{YEAR}-%{MONTHNUM}-%{MONTHDAY}[T ]%{HOUR}:?%{MINUTE}(?::?%{SECOND})?%{ISO8601_TIMEZONE}? and your date is not in that format. There doesn't seem to be a predefined pattern for you, so here's one that will work: %{DAY} +%{MONTHDAY} %{MONTH} %{YEAR} +%{TIME} %{WORD} Note that %{TZ} doesn't like GMT, so I used %{WORD}. Good luck....
The grok filter can be configured with multiple patterns: grok { match => [ "message", "%{DATA:php_error_type}: %{DATA:message_part1}%{URIPATHPARAM:file_name}%{GREEDYDATA:errormsg}", "message", "%{DATA:php_error_type}: %{GREEDYDATA:errormsg}", "message", "%{DATA:message_part1}%{URIPATHPARAM:file_name}%{GREEDYDATA:errormsg}", ] } (Instead of a single filter with multiple patterns you could have multiple grok filters, but then you'd probably want to disable the _grokparsefailure tagging with tag_on_failure...

In Grok, you'd need the following regex with a named capture group: \((?<name>[^()]*)\) This will match a text inside parentheses excluding parentheses. To include them, just put them into the capturing group: (?<name>\([^()]*\)) The negated character class [^()]* matches 0 or more characters other than ) and (. UPDATE: As...

The is malformed at "Mar/2014:15:36:43 +0100" part of the error message indicates that the timestamp parser has a problem with the month name.

Use the useragent filter to parse such fields. filter { useragent { source => "field-with-useragent" } } It won't extract the WOW64 string, though, but I doubt it's very useful anyway (and I'm sure not all browsers provide it). That said, you could look for that string yourself with a...
