# Observability Components

This page lists all the containers that are running with the Observability, with an explanation of its purpose as well as specific configurations for each container.

!!! info
	There is only **one** Observability running in any given time that will cover any number of environments that are deployed for any Critical Manufacturing MES infrastructure.

## ClickHouse

ClickHouse a fast and resource efficient open-source database for real-time apps and analytics. For more information, see <https://clickhouse.com/>.

!!! info
	The observability stack may use an external ClickHouse as an alternative to the integrated ClickHouse.

## Grafana

Grafana is used to visualize the data from various Data Sources. It allows for a convenient way to build dashboards and set up alarms to monitor the state of the diverse containers and applications. For more information, see <https://grafana.com/>.

## Otel Collector

The Otel Collector serves as a mediator for the telemetry data through pipelines.
Otel Collector ensures that all telemetry data flows through a centralized point, allowing for a more comfortable experience while adding new sources and destinations for the telemetry data. For more information, see <https://opentelemetry.io/docs/collector/>.

The OTEL collector can use various exporters. Currently, the ClickHouse Exporter is being used, which allows data to be exported after it has been processed by the OTEL processor.

## Traefik

Manages routing including port assignment and redirection. It also balances and forwards network traffic between the stack and the outside world, as well as handling certificate validations to ensure secure connections. For more information, see <https://doc.traefik.io/traefik/>.

Traefik is also responsible for redirecting the requests sent from different source that are supported by the single observability stack, depending on the URL that forms the request.
