📝 MongoDB Logging: Tailing the Queries

Are you tired of searching for a solution to log all queries in MongoDB? 🤔 Have you tried various methods, only to find yourself staring at a log file showing just the number of active connections? 😫 Don't worry, we've got you covered! In this blog post, we will tackle this common issue and provide you with easy solutions to tail your MongoDB queries. 🚀

But first, let's address some potential problems you might have encountered:

1. Setting the Profiling Level: Setting the profiling level is a common approach to enable query logging in MongoDB. However, if you are still not seeing all the queries in your log file, it may be due to a low profiling level. By default, the profiling level is set to zero, meaning no queries will be logged. Try reconfiguring the profiling level to a higher value, such as 1 or 2, by running the following command:


2. Slow ms Parameter: Another method to log queries is by setting the "slow ms" parameter. If you've already adjusted this parameter but still don't see the desired output in your log file, it's possible that your queries are not considered slow according to the specified threshold. You can try lowering the "slow ms" value to capture more queries:

db.setProfilingLevel(1, { slowms: 1 })

3. Mongod with -vv Option: Using the -vv option with the mongod command is supposed to enable verbose logging, including query information. However, if you're not getting the expected detailed output, it may be due to other log levels overriding the verbosity. In this case, you can explicitly set the log level to 5 by modifying your MongoDB configuration file:

  verbosity: 5

Now that we've covered the potential issues and their solutions, it's time to make a compelling call-to-action to engage our readers! 💪
