Part of their web page looks likes like this. To use that, open the mongo shell and then paste in this command: db.enableFreeMonitoring() That’s hosted on their web site, but that does not mean you need to use their cloud service (Atlas). You should take advantage of the free monitoring service offered by MongoDB. So limiting it in one place will cut make it consume more in the other. But MongoDB uses both its internal cache and the system’s file system cache. You can limit the MongoDB cache size by adding the cacheSizeGB argument to the /etc/nf configuration file, as shown below. MongoDB, in its default configuration, will use will use the larger of either 256 MB or ½ of (ram – 1 GB) for its cache size. So people have reasoned that if your computer is running out of memory then you should limit the memory made available to MongoDB. In sum, the mongod process will consume more and more memory as it fills up its cache. There is much bad information on StackOverflow about what to do when your server runs out of memory. But it makes liberal use of cache, meaning data records kept memory for fast retrieval, as opposed to on disk. Although it can be configured to run that way. Use the right-hand menu to navigate.) When MongoDB Runs Out of Memory, Add Another Node (This article is part of our MongoDB Guide. Then we added 3.5 GB of data at which point it locked up when it reached 92% memory usage.
Then we show what the logs looks like and what tools you can use to monitor this situation.Īt 215 MB of data this server consistently used 11% of memory when hitting it with multiple searches. We illustrate what a server looks when it runs out of memory by purposely adding more data to an 8 GB machine than it can support and then running queries against that. The solution to this is add another node to your cluster. It can do that quickly too, so quick that you will not even be able to shutdown the mongo db process as the bash shell will no longer respond. If you put too much data in your MongoDB database, it will run your server out of memory.
