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.

"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"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."

Room for Improvement

Grafana Loki faces issues with stability and compatibility with ECS, not Kubernetes. Users find its dashboards outdated compared to others, wish for direct Windows Server log access, and desire customized reports. Its query language has usability challenges, and more robust debugging tools are needed. Production setup complexity limits adoption, and alerting features could improve. Speed enhancements and AI integration for predictive analytics are suggested, along with a more intuitive user interface.

"I would rate Grafana Loki a seven out of ten because it is open source, and sometimes there can be problems that are difficult to fix without official support."
"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."

ROI

Grafana Loki setup is quick and efficient. Users report a positive ROI due to the free on-premises version and affordable cloud option. Companies benefit from time savings and reduced server downtime. Engineers resolve issues faster, enhancing cost savings.

Pricing

Many enterprises find Grafana Loki's open-source version cost-effective without incurring licensing or setup fees. While the on-premises version is free, the cloud version is competitively priced. Pricing structures may vary by user count and could include additional taxes. Mostly, organizations prefer its affordability and flexibility, drawn by its open-source nature. The enterprise version may require licensing fees, but many companies successfully use the free offering to meet their needs.

"The cost is less than other paid services like CloudWatch."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"Grafana Loki is an open-source solution."

Popular Use Cases
