Monitoring MongoDB’s Engines in the Wild

Monitoring MongoDB’s Engines in the Wild

 4 October 12:20 PM - 1:10 PM @ Matterhorn 3
Experience level: 
50 minutes conference


MMAP has long been used and monitored in the MongoDB ecosystem. Now, however, there are new players in the form of WiredTiger and RocksDB. In this session, we will break down all of the metrics output by these engines and talk about what they mean. We will also discuss how you might group metrics together to understand their interaction so as to explain spikes in queues, CPU, memory and other areas.
