Logstash is most known for being part of the ELK Stack while Fluentd has become increasingly used by communities of users of software such as Docker, GCP, and Elasticsearch. When it comes to processing all of your log information in a single place, LOGalyze comes helpful. Assemblage is accomplished via configurable input plugins with raw socket/packet communication, file tailing, and several system messages. In logs file, we will have each and every piece of information such as application log, system log, event log, script log, rewrite log, and process ID, etc. Below is pyspark code to convert csv to parquet. For a 8 MB csv, when compressed, it generated a 636kb parquet file. This real-time analyzer can be updated on the terminal in every 200 ms. Supports regular expressions like Grep/Egrep. LOGalyze does its job quite impeccably with the focus on log management. Multitail can make the functionality of tools like “watch”. Capability to describe event handlers to be route during service or host events for hands-on problem resolution. Offers a web-based customizable user interface based on HTML. The output is paged through less by default and long lines are “truncated” to screen dimension. Configuration can be set from the command line. It was written from scratch using an object-oriented design. Depending on your business use case, Apache Parquet is a good option if you have to provide partial search features i.e. This open-source log viewer tool is now called Swatchdog. Columns of same date-time are stored together as rows in Parquet format, so as to offer better storage, compression and data retrieval. In columnar storage format above table will be stored column wise. Support for a system-wide entry database & personal entry database. This tool has protection from DOS attacks. Gives instant information about security problems. Queries selecting few columns from a big set of columns, run faster because disk I/O is much improved because of homogeneous data stored together. For example above table has three columns of different data types (Integer, String and Double). Logwatch sends instant log alert when any security Breach or performance issue happened. Shows log more than one files in multiple windows. Even if you need a visual server report in haste, it comes quite handy with very fast HTTP statistics. Has predefined templates to display data. Thus, you can get your desired data quite easily with this Linux log viewer. It has multiple virtual hosts, so you can monitor which virtual host is consuming most of the server resources. For a 8 MB csv, when compressed, it generated a 636kb parquet file. So let’s get started. If you are a Linux lover, you must have some knowledge about Linux log viewer tools. It can recap logs from different machines in a single report. 我们产线上使用 logstash-input-file 从文件抓数据，然后通过logstash-output-kafka 将数据发送到kafka，现在就是output线程使用CPU很高。1. This Linux log viewer runs on Unix systems, Windows and Mac OS. Suricata inspects the network traffic using a powerful and extensive rules and signature language, and has powerful… scans log files and present data in a human-readable form. Powerful search option, including a smart filtering system. Files will be in binary format so you will not able to read them. User can easily monitor all the logs from one window. Send real-time alert notifications to admin in various ways like email, text, and Slack. This Linux log file viewer is an easy and widely used tool that allows a system administrator to analyze the log files created upon hosts under their control. 这个时候就可以配置Logstash采集数据然后想es输入了，但是我们并不满足于此，我想在需要采集日志的应用服务器上安装 filebeat，然后经filebeat将数据转发给Logstash，Logstash只进行过滤即可（也可以filebeat直接将数据传给es，不要Logstash，看个人需求）。 For more information about parquet schema and performance comparisons with other storage formats you can refer to Parquet official docs. The other way: Parquet to CSV For Introduction to Spark you can refer to Spark documentation.
