Integrations enhance monitoring but problem-solving proves challenging
Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself. As part of Kubernetes technology, I noticed benefits from using this product such as availability, configuration balancing, high availability solutions for high performance, and failover clustering. It provides a clear picture about the state of the system and gives needed information for taking action and quickly fixing problems.
Vinay Patel D N - PeerSpot reviewer
Effective with good log analytics but needs better rule correlation
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk. Sometimes logs will not fetch, and there are issues if the log volume exceeds a threshold. Not every tool is integrated with Sumo Logic. The response time for their support could be better, and it is not very user-friendly.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best feature of Grafana Loki is that it integrates well with our other tool."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"Grafana Loki is easy to monitor and detect errors."
"There are new features like that pilot code and things like that for profiling."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"We are using Grafana Loki as a database for real-time metrics."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"Technical support is always great."
"Sumo Logic is an easy solution to use. You can set it up very quickly, and it includes a lot of training videos."
"We can integrate threat intelligence solutions into the product."
"I have no concerns about the stability of the product. I feel it handles the stress we put on it very well."
"It helps a lot because we can troubleshoot issues pretty easily."
"Sumo Logic Security offers a single dashboard and customization, which are the most valuable features."
"It gives us a bird's eye view of what's happening from our connection's point of view."
"We can ingest logs and make reports out of them. It is a good tool which can help us monitor any issues."
 

Cons

"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"There is a need for some change in the alerting types of the product. In short, a few changes in the alert area are needed due to minor shortcomings."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"We had a well-structured dashboard with a functional query. However, an issue arose when the Kubernetes pod restarted. The statistics from our Grafana query would reset, dropping to zero and starting anew. This was particularly noticeable with linear graphs, which are expected to show consistent growth."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"The solution should improve its UI."
"It would be nice to have an improved ability to scroll through logs within a time frame. Right now, we can search for specific errors. However, if we want to look for "before and after" within a specific time frame, it's not easy using the tool. This would be an improvement."
"There are some API gaps that are missing."
"The integration with multiple sources could be better."
"If you look at some of the other offerings right now that are available in the market, they do offer APM as well as the product they're offering. I believe Sumo Logic is not there yet. So that's something which I would love to see."
"The API integration in Sumo Logic Security could improve. There are delayed connections or they stop and then automatically start. Having a seamless log collection would be beneficial."
"The initial setup is the most stressful, like learning how to use it."
"We would like the ability to drill down into a dashboard and get into deeper levels."
 

Pricing and Cost Advice

"Grafana Loki is a free, open-source solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"I use the open-source version of the product."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"You can use the free version of Grafana Loki on-premises."
"The cost is less than other paid services like CloudWatch."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"I don't pay the bill. I've heard the AWS Marketplace pricing is high, but I like the value."
"The pricing is good. It's not an issue for us."
"Purchasing the solution through the AWS Marketplace is very easy."
"Storing logs in Sumo Logic Security is charged GB-wise, which is a little higher than other products."
"The pricing is a little high, but for the features that we receive from Sumo Logic, it suits the price. For some small organizations, the price might be a little high."
"If we went to ELK Stack, which is open source, it would have been less costly, but it would have required more development from our side."
"Pricing has been cheaper than some of the competing tools, like Splunk."
"The AWS Marketplace pricing is fairly reasonable for what it does. I wouldn't call it expensive, but I wouldn't call it cheap. It is pretty good."
