ObjectiveJMeter is an open source tool for performance testing, stress testing, and is being tested by a large number of testers to test product performance, load, and more. JMeter In addition to the powerful presets of various plugins, various visual charting tools, there are some inherent flaws, such as:
We often can only analyze the performance of the same deployment in the report, it is inconvenient to make a vertical comparison, for example, each build will run a one-time test, but
First, open the Kibana discover interface, and we'll find that the default entry in the search box at the top of the page is "*", which also means that the default query is all information.Now, suppose our import kibana information is divided into two categories: trace and statistic, and the two types of information are differentiated in info-type.Then, when we enter Info-type:trace in the search box above

The previous chapter introduced the use of Logstash, this article continued in-depth, introduced the most commonly used input plug-in--file.
This plug-in can be read from the specified directory or file, input to the pipeline processing, is also the core of Logstash plug-in, most of the use of the scene will be used in this plug-in, so here in detail the meaning of each parameter and use.

In addition to accessing the log, the log is processed, which is written mostly by programs, such as log4j. The most important difference between a run-time log and an access log is that the runtime logs are multiple lines, that is, multiple lines in a row can express a meaning.In filter, add the following code:Filter {Multiline {}}If you can do it on multiple lines, it is easy to split them into fields.Field Properties:For multiline plug-ins, there are three settings that are important: negate,
