What is Grafana Loki?

Grafana Logs (powered by Loki) brings together logs from applications and infrastructure in a single place. By using the exact same service discovery and label model as Prometheus, Grafana Logs can systematically guarantee logs have consistent metadata with metrics.

Grafana Logs lets users send logs in any format, from any source so it’s easy to add to existing infrastructure and get up and running quickly.
  • Leverage a wide array of clients for shipping logs like Promtail, Fluentbit, Fluentd, Vector, Logstash, and the Grafana Agent, as well as unofficial clients.
  • Promtail, Loki's preferred agent, can pull in logs from many sources, including local log files, the systemd journal, GCP, AWS Cloudwatch, AWS EC2 and EKS, Windows events logs, the Docker logging driver, Kubernetes, and Kafka.
  • There aren’t any ingestion log formatting requirements — all formats welcome including JSON, XML, CSV, logfmt, unstructured text.

Grafana Loki is open source, horizontally scalable, highly available, multi-tenant log aggregation system inspired by Prometheus. It is for users who prefer to set up, administer, and maintain their own installation.

Alternately, offered as a fully managed service, Grafana Cloud Logs is a log aggregation system based on Grafana Loki. It is Managed and administered by Grafana Labs with free and paid options for individuals, teams, and large enterprises. And the Enterprise Logs option is a self-managed logging solution that runs securely at scale with expert support from Grafana Labs.

Use Cases and Deployment Scope

Loki is used for service process logging and sharing of logging data with other services and display dashboards. Engineers can use Loki as a logging repository to enhance troubleshooting and error tracing as issues arise. Loki, used with Grafana, provides a more user-friendly user interface that less adept engineers can use to query logs.

Pros

  • Compile logs.
  • Offer modular access.
  • Track and trace log queries.

Cons

  • Offer log suggestions.
  • Offer basic query syntax check.
  • Offer data range controls.

Return on Investment

  • Enable engineers to access logs quickly to distribute the workload.
  • Provide a possible standard for log access between multiple services.
  • Provide data metrics for customer use.

Use Cases and Deployment Scope

As Grafana Loki is open-source logging and monitoring solution. We are using Kubernetes Cluster for our application deployment we are using Loki for Log aggregation of pods logs, jobs logs, and nodes logs, so we don't have to give access to Kubernetes cluster. Also, we are using Grafana for monitoring our Infrastructure, Cluster, Nodes Monitoring, Pods Monitoring, and our public cloud service provider.

Pros

  • Access to many open-source dashboards, access to add many data-sources to gather and visualize data from.
  • Grafana Loki does well gathering of logs from various data-sources, we can also filter the logs based on our needs.
  • One stop solution for all the logs and monitoring.

Cons

  • We can modify the logs directly from UI of Grafana Loki
  • Better and simplified options for logs filtering
  • Easy usability with SMTP configuration and other system level configuration

Most Important Features

  • Logs gathering and monitoring from various data-sources
  • Access control
  • One stop solution for monitoring and logging

Return on Investment

  • Only indexes the metadata
  • Have to manage it by ourselves compare to other available managed monitoring and log observability solutions
  • Dedicated person or team of SRE to manage the monitoring and observability solutions
