From the perspective of metric visualization — custom or standard solution?

When choosing between a custom solution for displaying metrics and using standard libraries or frameworks, several factors should be considered:

• Reliability and Provenance: Standard solutions, such as the Prometheus client for C#, are well-tested and supported by the community.
• Development Time: Using ready-made libraries significantly reduces implementation time and the likelihood of errors.
• Flexibility: A custom solution can be tailored to specific requirements but requires additional resources for maintenance and development.
• Integration: Standard solutions are usually easy to integrate with monitoring and alerting systems.

In practice, it is recommended to use standard solutions if they meet your requirements. Custom implementations are justified only in cases of unique needs that cannot be satisfied with ready-made tools.

For example, in C#, you can use the Prometheus-net library to export metrics:

using Prometheus;

var counter = Metrics.CreateCounter("my_counter", "Counts something");
counter.Inc();

This allows for quick and reliable collection and display of metrics without unnecessary development costs.
