Engineering Lead- Cloud and Platform Architecture at a financial services firm with 1,001-5,000 employees

If it is HelloGuard setup or doing some setup on the dev cluster, it's pretty straightforward. But when we're dealing with a heavy cluster, like 15 to 20 terabytes of data per day, we need a production-grade cluster. For that kind of scenario, we must invest time and understand the process. We could have integrated these features within their health check, but they're using processes like Tanka and Jsonnet to implement a production service. I feel this could have been better. If I use a metric solution for metrics, I'd use Grafana for metrics monitoring. For logging, I'd use a different tool, like ELK. And for tracing another tool. So, to troubleshoot a specific issue, I have to switch between three different consoles. What I see in metrics isn't the same as in logs because the metadata and collection methods differ. That's where Loki comes in. Within Grafana, you can see metrics, logs, correlations, generate metrics from logs, and also set alerts. Alerting from logs is something many companies desire. With Loki, if there's a pattern in the log, we can filter it out without altering the entire pipeline. For instance, if I had to add fields in ELK, it would require a lot of configuration changes. Loki, however, is more flexible. It uses a grep-like pattern and the metadata model from Prometheus. It's highly efficient, with compressed data and block storage like GCS bucket or AWS S3, making log storage cost-effective. Compared to other solutions, it's more economical. Loki also has a Log CLI, which is very effective. It's all on-premises. Like, it's on the cloud, but it's self-managed, not a managed service.

Before implementing it, we lacked insight into the status of our HCI infrastructure. Now, we have the capability to directly monitor both our infrastructure and APIs. This enables us to determine whether our APIs and infrastructure are performing optimally and provides us with valuable information about the programs and systems we rely on.

Valuable Features

Grafana Loki's most valued features include simple dashboard creation, open-source stability and flexibility, effective log processing for microservices, cost-efficient storage with S3, seamless Prometheus metadata integration, robust alert setups, advanced filtering for log data analysis, user-friendly GUI, ease of deployment in multi-cluster environments, object-based storage, real-time metric management, straightforward error monitoring, lightweight processing capabilities, quick log filtering, and Kubernetes-native management.

"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."

Room for Improvement

Grafana Loki needs better request flow visualization and request correlation. The alert creation process should be streamlined. Reports require customization to include specific metrics. Security monitoring features and query intuitiveness need enhancement. UI and dashboard versatility could improve. Issues with Docker containers and alerting limitations exist. Integrations with proprietary services like ECS are complex. Speed and stability are concerns. Access to Windows Server logs from servers would be beneficial.

"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"I do not see any areas for improvement at the moment."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
