Volodymyr Bondarchuk - PeerSpot reviewer
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

"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The log collection feature is good and the solution is easily understandable. v"
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"There are new features like that pilot code and things like that for profiling."
"I have no concerns about the stability of the product. I feel it handles the stress we put on it very well."
"Scalability has been good for our needs. We haven't run into any scaling issues in regards to size so far."
"The most valuable features of Sumo Logic Security are the rules, use cases, and ease of use. Additionally, the integration is straightforward and good GUI."
"Sumo Logic is an easy solution to use. You can set it up very quickly, and it includes a lot of training videos."
"It helps a lot because we can troubleshoot issues pretty easily."
"The features I found valuable with the Sumo Logic Security solution are the search option and the ability to customize the search for the information in the logs."
"Sumo Logic Security is a good solution for searching the logs and identifying the issues."
"We use it to ingest Windows domain controller logs. We use this to monitor if anyone is placed in particular administration groups that potentially shouldn't be. It helps us keep track of people."
 

Cons

"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."
"The platform's stability needs improvement."
"I do not see any areas for improvement at the moment."
"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."
"The product must improve its UI."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"We face some bugs when we install the latest version of Grafana Loki."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"From the network segmentation side, there is some discrepancy in log onboarding. The tool needs to improve direct API integrations, login integration, native login integration, etc."
"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 correlation rules and log mapping are not as mature compared to other SIM tools like Splunk."
"We would like the ability to drill down into a dashboard and get into deeper levels."
"In terms of improvement, feedback indicates there is a need for a local data center in my country. This is crucial to sell to the government and financial sectors as they require data retention within each country."
"There are some API gaps that are missing."
"Sumo Logic needs to make sure integrating solutions are seamless."
"It took a bit of trial and error to get it set up correctly based on everything we had to do. In the end, we had to send everything over HTTP, which was sort of a stop-gap."
 

Pricing and Cost Advice

"Grafana Loki is an open-source solution."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"My company doesn't need to pay for the licensing cost of the solution."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"The solution is open source."
"Grafana Loki is a free, open-source solution."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"We use a free version."
"Purchasing the solution through the AWS Marketplace is very easy."
"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."
"The license pricing model is based on the events that are processed through the solution."
"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."
"The only limit to the scalability of the product for us is how much we are willing to pay."
"The AWS Marketplace pricing is borderline. Every annual renewal, we always contemplate if we are getting what we think we could out of it or could we do it cheaper with some other product."
"The product is costly."
"The pricing is good. It's not an issue for us."
