The ability to monitor your Sitecore instances is essential. Knowing your application is available and performing in production as expected is critical. To be proactive and respond to changes in performance as opposed to reactive after an incident has occurred, you need a continuous overview of the state of the application and the underlying infrastructure. This involves gathering metrics like CPU, memory usage, and storage consumption as well as any application-related metrics. However, when monitoring a containerized Sitecore instance we cannot apply our usual methods and tools to provide us with all the data we need. In this post, I will show you some of the native tools to help you monitor Sitecore containers.
Docker stats
The docker stats command display a live stream (updated every second) of running containers resource usage statistics docker stats:
- CPU % – the percentage of the host’s CPU the container is using.
- PRIV WORKING SET – refers to the total physical memory (RAM) used by the process.
- NET I/O – the amount of data the container has sent and received over its network interface.
- BLOCK I/O – the amount of data the container has read to and written from block devices on the host.
