How to exclude cached/buffered RAM from "used RAM" do-agent monitoring?

Hi guys. Does anyone know how to exlude cached/buffered bytes from “memory utilization” monitoring stats? We do have a condition to warn us if the memory utilization is above 90% for 10 minutes, but we get this notification even if there is most of ram available. It looks like do-agent sums used ram and cached/buffered numbers and returns that sum as a “used ram”. Thanks

  • I’d like to know if this is possible. Currently our droplet is using 11% of “real” RAM but we constantly receive that notification due to cache taking us above the 90% threshold

Hello,

With the new monitoring agent, this should work as expected, as cached memory is available on demand it is not considered to be in use.

Here’s a step by step guide from the official documentation on how to upgrade your monitoring agent:
