You can have a look at logstash and/or beats. ---

logstash and/or beats can not do any thing. such as myself plugin. I hope it can send command to my plugin when es starts. ---

I have completed the plugin' development that can synchronize data from mongodb to es. It will synchronize data from mongodb to es immediately when mongodb changes. now. I need es send a piece of command to monitor mongodb's state when es starts. maybe beats could not get my requirement, is it? ---

You could write a mongodb beat if you wish. That said, packetbeat already listen to what is happening at a network level to your mongodb instance. Might do part of the job you are looking for? Think about beat as the E part of ETL. It collects data. ---
