Data acquisition of Kafka and Logstash
Based on Logstash run-through Kafka still need to pay attention to a lot of things, the most important thing is to understand the principle of Kafka.
Logstash Working principleSince Kafka uses decoupled design ideas, it is not the original publication subscription, the producer is responsible for generating the
Logstash cannot read redis data
A problem occurred when constructing logsatsh + redis + elasticsearch today. After nearly one hour of troubleshooting, the problem was finally solved. Record it.
The environment is like this. A client sends data to redis on the server, and logstash on the server reads redis data and stores it in elasticsearch.
The initial problem is that on the server side, the log sent from
Flume compared with Logstash, the personal experience is as follows:
Logstash more emphasis on the preprocessing of the field, while flume emphasis on data transmission;
Logstash has dozens of plug-ins, flexible configuration, Flume is to emphasize the user's custom development (source and sink kind also has ten or twenty, the channel is relatively s
When we use Logstash to collect logs, we usually use the dynamic Index template that comes with logstash, although we can push our log data to the Elasticsearch index cluster without any custom action, but when we query, we find that The default index template often puts us in a field that does not need a word breaker, so that our more important aggregated statistics are inaccurate:For example, if there are

Background: At present, there is a database data about 300 million in the business. If the query directly from the database, wait more than 15 minutes, the user often want to view the data, can only write SQL in the database directly query after drinking a few cups of tea, the results have not come out. The user sees the use of the ES cluster in our project and wants to synchronize the data in the database to the ES cluster.Software version: logstash-
