Rsyslog is a log collection tool. Currently, many Linux systems use rsyslog to replace syslog. I will not talk about how to install rsyslog. I will talk about the principle and the configuration of logstash.

When cleaning logs, there is an application scenario, that is, when the TCP output, you need to switch to the next available entry when a host fails, the original tcp output only supports setting a single target host. Therefore, I developed the tcp_multihost output plug-in based on the original tcp to meet this scenario.

Recently helped Lei elder brother transplant a set of open source log management software, replace Splunk. Splunk is a powerful log management tool that not only adds logs in a variety of ways, produces graphical reports, but, most of all, its search capabilities-known as "Google for it." Splunk has a free and premium version, the main difference is the size of the index per day (index is the basis of the search function), the free version of the maximum daily 500M. When using the free version,

Use logstash to collect php-fpmslowlog. Currently, the php-fpm service is deployed in docker. the php-fpm log and php error log can be sent through the syslog protocol, however, the slow log of php-fpm cannot be configured as a syslog protocol and can only be output to files, because an slow log consists of multiple lines.
To collect slow logs, you can collect them using tools such as logstash and flume.
Logstash is mainly used for data collection and analysis, with Elasticsearch,kibana easy to use, installation tutorial Google out a lot.Recommended Reading

Index fields are indexed using automatic detection in ES, such as IP, date auto-detection (default on), Auto-detect (default off) for dynamic mapping to automatically index documents, and when specific types of fields need to be specified, mapping can be used to define mappings in index generation.
