=========== logstash 客户端起不来： java memory, 允许的最大process/threads

Before:

elk:
./logstash-plugin install logstash-input-jdbc

./logstash-plugin install logstash-filter-json

就安装好logstash-input-jdbc插件了，然后我们进入logstash根目录下的以下目录查看对应的插件版本：

# cd ../vendor/bundle/jruby/1.9/gems/logstash-input-jdbc-4.2.3
# ./logstash-plugin prepare-offline-pack --overwrite --output logstash-input-jdbc-4.2.3.zip logstash-input-jdbc
Offline package created at: logstash-input-jdbc-4.2.3.zip
