Monitor Logstash is a special data processing element that receives information from different servers at the same time, and then modifies and delivers it to a special system. Logstash is also a tool for collecting, normalizing and filtering logs.
The configuration file format is as simple and straightforward as possible. It includes 3 parts – input, filter and output blocks, which can be unlimited. How much of them you need depends on your particular needs.
The first one – input – acts as the entry point for the logs. There, it is determined which channels will be used for the logs that will ultimately end up in Logstash.
The next block – filter – sets up basic manipulations with logs. Here you can split, remove unnecessary parameters, replace existing values, use the appropriate queries for IP addresses or host names.
The last block is the output, and its name speaks for itself. The settings for outgoing messages are indicated there. As in the previous blocks, it is allowed to specify an unlimited number of outgoing subblocks here. All functions are simple and accessible.
Goals of Logstash
Based on how data moves from the source to the repository, server pipeline filters perform a detailed analysis of each current action, perform recognition of named fields in order to build structures and remake them into a common format. The purpose is to conduct effective and accurate analysis and add value to your business.
The main purpose of monitoring Logstash is to dynamically transform and prepare information, regardless of its format or complexity. You also need Logstash in order to.
- make structures from unstructured data using the grok function.
- decrypt geocoordinates from the unique numeric identifier of a device in a computer network operating over the TCP/IP protocol.
- make personal data anonymous, remove fields that increase the risk of a breach of confidentiality.
Logstash guarantees the ease of general processing of any data source. On the SHALB website, there is an opportunity to get acquainted with the principles of work according to this scheme in more detail. Contact the staff for details.
