| ## Setting up Coroot for FerretDB monitoring | ||
|
|
||
| Since Coroot uses eBPF, you need the right environment before setting it up. | ||
| The most recent versions of the Linux kernel (v 4.16 and above) should be compatible since they offer at least minimal eBPF support. |

| The Coroot dashboard provides the full details on all components. | ||

||
| At first glance, we can see a memory leak on the `ferretdb` and `postgres` databases. | ||
| That suggests that allocated memory is not being efficiently reused or deallocated, causing the total memory usage to grow progressively as the services operate. |

… so we want to publish a blog post that casually mentions that FerretDB and PostgreSQL have memory leaks just like that?

| Using distributed tracing, Coroot provides a heat map showing operation requests, their status, durations, and details. | ||

Why do we write something that has nothing to do with FerretDB?

| The above image shows how response time for the `ferretdb` increased progressively over time. | ||
| It shows that the system takes a long time to handle queries. | ||
| That should prompt us to take additional measures to improve performance. |
