logstash patterns

Grok-patterns contains log parsing rules for regular expressions with many underlying variables, including Apache log parsing (which can also be used for nginx log parsing). Based on Nginx log analysis configuration: 1. Configure the Nginx log format as follows: Log_format main ' $remote _addr [$time _local] "$request" $status $body _bytes_ Sent "" $http _referer "" "$request _time" '; access_log/var/log/nginx/access.log main; The Nginx log is screen

fields. This is very useful for parsing and querying our own log data in the future. For example, HTTP return status codes and IP addresses are very easy. Few matching rules are not included by the grok, so if you are trying to parse some common log formats, someone may have done this. For details about the matching rules, see logstash grok patterns. Another filter is date filter. This filter is used to pa

This filter looks for logs marked as "Syslog" type (by Filebeat) and will attempt to parse the incoming syslog log using Grok to make it structured and queryable. Create a configuration file named Logstash-simple, sample file: Vim/etc/logstash/conf.d/

Logstash + Kibana log system deployment configuration Logstash is a tool for receiving, processing, and forwarding logs. Supports system logs, webserver logs, error logs, and application logs. In short, it includes all types of logs that can be flushed. Typical use cases (ELK ): Elasticsearch is used as the storage of background data, and kibana is used for front-end report presentation.

SummaryWhen we use Logsatsh to write the configuration file, if we read too many files, the matching is too much, will make the configuration file hundreds of thousands of lines of code, may cause reading and modification difficulties. At this time, we can put the configuration file input, filter, output in a different configuration file, or even the input, filter, output again separated, put in a different file.At this time, the later need to delete and change the contents of the search, it is

It's hard to find logstash Chinese material on the internet, Ruby didn't know it, it was too difficult to read official documents, and my requirements are not high, using Loggstash can extract the desired fields.The following is purely understandable:Logstash Configuration Format#官方文档: http://www.logstash.net/docs/1.4.2/input {... #读取数据, Logstash has provided very many plugins, such as the ability to read d

First, Logstash Logstash: It is a flexible data transmission and processing system that is responsible for the collection before the beats comes out. Logstash's task is to put all kinds of data, through the configuration of conversion rules, unified into the Elasticsearch. The Logstash developed with Ruby is a great flexibility.
