The VictoriaMetrics Observability Blog

We’re happy to announce VictoriaMetrics Cloud, a hosted monitoring platform and managed service for metrics that allows organizations to monitor and store large amounts of time-series data, without having to run the underlying infrastructure.

Map is a built-in type that acts as a key-value storage. Unlike arrays where you’re stuck with keys as increasing indices like 0, 1, 2, and so on, with maps, the key can be any comparable type.

I have already recorded metrics in the application, why can’t I see my metrics on Grafana?

Mutex in Go has two main flows: Lock and Unlock and 2 modes: Normal and Starvation Mode. The state field of mutex is a 32-bit integer that represents the current state, it’s divided into multiple bits that encode various pieces of information about the mutex.

As always, we’ll start with the basics and then dig a bit deeper. Don’t worry, Go arrays get pretty interesting when you look at them from different angles. Arrays in Go are a lot like those in other programming languages. They’ve got a fixed size and store elements of the same type in contiguous memory locations.

The defer statement actually has 3 types: open-coded defer, heap-allocated defer, and stack-allocated. Each one has different performance and different scenarios where they’re best used, which is good to know if you want to optimize performance.

Vendoring is a different strategy as it keeps a copy of all your project’s dependencies directly within the project’s directory, rather than relying on an external cache.
