In this issue, the editor will bring you about how to achieve index increment statistics in Elasticsearch. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

1. Problem decomposition 1.1 data volume statistics of ES cluster

Examples of command line statistics included with ES:

How does curl 'localhost:9200/_cat/indices?v'1.2 implement increments?

Simplified ideas: 1) every day at a fixed time, such as 00:00 in the morning to count the amount of data of the day, to form a log file storage such as: 20180228-00:00.log2) 20180228 increment: 20180229-00:00.log data value-20180228-00:00.log data volume. (next day-the day before)

1.3 how to realize statistics

Simplified ideas: 1) shell script to obtain the amount of data counted every day; 2) simple calculation increment of Excel formula

1.4 how to realize timed mail statistics

Simplified ideas: 1) java + mail program + read script implementation. 2) crontab realizes timing task processing.

2. Realize 2.1 daily data statistics.

The returned result is as follows:

2.2 Java read Shell script

2.3 incremental data statistics

Step 1: daily data statistics.

Step 2: incremental data statistics. Step 1, step 2 data can be obtained by Excel statistics.

The copy shell script for daily data is as follows:

Step 3:Excel generates the chart.

This is how to achieve the index increment statistics function in the Elasticsearch shared by the editor.
