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.

Offers a single dashboard with customizable features and a cost-effective pricing structure
Sumo Logic Security offers a single dashboard and customization, which are the most valuable features. Additionally, it has a cost-effective structure because it is based on data storage and the number of scans, rather than uploading data. This cost model impacts the customers positively by offering a more straightforward pricing structure.

Quotes from Members

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

Pros

"The log collection feature is good and the solution is easily understandable. v"
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"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."
"There are new features like that pilot code and things like that for profiling."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"The tool can be used in multi-cluster environments."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"We can ingest logs and make reports out of them. It is a good tool which can help us monitor any issues."
"Sumo Logic Security is a good solution for searching the logs and identifying the issues."
"Technical support is always great."
"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 Security offers a single dashboard and customization, which are the most valuable features."
"With this tool, we provide access to every developer team the ability to find errors, then they come to us and ask for specific help."
"The Log Analytics platform is the most effective. If we cannot find the data in other tools, like email security or NDR, we can fetch those logs in the Log Analytics platform of Sumo Logic."
"We can integrate threat intelligence solutions into the product."
 

Cons

"The correlation of requests is not simple in Grafana Loki and can be improved."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"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."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"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."
"In my opinion, this solution has a steep learning curve and requires practice if users to be able to use this tool very efficiently."
"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."
"The integration with multiple sources could be better."
"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."
"The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk."
"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."
"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."
 

Pricing and Cost Advice

"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."

"The price scaling comes in a bit expensive."

"The product is costly."
"The only limit to the scalability of the product for us is how much we are willing to pay."
"Purchasing the solution through the AWS Marketplace is very easy."
"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 license pricing model is based on the events that are processed through the solution."
