Grafana Loki
Aggregate, process and save log files efficiently and quickly
Log management system
Grafana Loki is an open source tool for the efficient management of log data that is very similar to Prometheus.
You can use it to collect and search large amounts of logs without having to index the full content of the logs, which makes it resource-efficient. Loki integrates seamlessly with Grafana so you can visualize and analyze log data alongside your metrics to quickly identify issues in your infrastructure.
Grafana Loki Features
Efficient log management
Grafana Loki collects and stores log data without fully indexing it, which is more resource-efficient compared to traditional logging solutions. You can use it to process large volumes of logs without using significant memory and computing resources. This makes Loki particularly suitable for environments with many microservices or containers.
Integration with Grafana
Loki integrates seamlessly with Grafana so you can visualize log data along with metrics and dashboards. This allows you to analyze logs and metrics in parallel to diagnose problems such as performance drops or errors more quickly. This integration significantly improves the transparency and monitoring of your infrastructure.
Label-based queries
Instead of indexing all logs, Loki uses labels, similar to Prometheus for metrics. You can organize and quickly search log data by adding specific labels (e.g. server name or application name). This enables you to carry out a very efficient and targeted analysis without having to perform time-consuming queries across huge amounts of data.

Questions & Answers
The most frequently asked questions about Grafana Loki
What is Grafana Loki?
Grafana Loki is an open source tool for managing and analyzing log data that has been optimized for integration with Grafana. It stores logs without full indexing, making it a lightweight alternative to other log management solutions. With Loki, logs can be efficiently collected, stored and searched to better monitor the infrastructure.
How does Loki work compared to traditional log management tools?
In contrast to traditional log management tools, Loki does not index the complete log content, but only the labels assigned to the logs. This significantly reduces memory requirements and makes queries faster and more efficient. The label-based approach allows you to search for specific log data without having to search through all logs.
How does Loki integrate into Grafana?
Loki integrates seamlessly with Grafana and allows you to display logs alongside metrics in your dashboards. This integration allows you to correlate log data and metrics in real time and thus quickly identify the causes of problems in your infrastructure. The combination of Loki and Grafana is ideal for comprehensive monitoring of your systems.
Which data formats are supported by Loki?
Loki can process logs in various formats, including simple text logs, JSON and structured logs. It is designed in such a way that it can handle different data sources and formats flexibly. User-defined log formats can also be organized using labels to facilitate targeted queries.
What are Loki labels and how do they help with log management?
Loki uses labels to categorize logs instead of creating complete indexes. Labels such as "Job", "Hostname" or "Application" allow logs to be searched and queried more efficiently. This approach saves storage space and speeds up the search for relevant logs.
Can Loki be used in cloud and container environments?
Yes, Loki is ideal for cloud-native and container environments such as Kubernetes. It can capture log data from containers and be used in conjunction with Prometheus and Grafana to monitor metrics and logs together. Loki was developed specifically for modern, distributed infrastructures to facilitate the management of large amounts of log data.
