Mongo service crashed. Need to find reason of crash

Question

Today morning I found the following error with mongo, on my server.

*** System restart required ***
You have mail.
ubuntu@ip-xxx-xx-xx-xx:~$ mongo
MongoDB sh         


        

Answer 1

According to MongoDB documentation

The getLog command returns a document with a log array that contains recent messages from the mongod process log.

Please try executing following command in mongo shell to return logs which consist of information related to errors or warnings while initialization of mongod service

db.adminCommand({getLog: "startupWarnings" })

For detailed description regarding getLog method please refer the documentation mentioned in following URL
