Efficient log filtering enhances quick network troubleshooting
We use Grafana Loki for various verticals including manufacturing, finance, health, and aerospatial sectors. It primarily helps in monitoring security and access to devices. Grafana dashboards are used to track access success and failure and audit commands issued on devices Loki significantly…
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 effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"Grafana Loki is easy to monitor and detect errors."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"We can integrate threat intelligence solutions into the product."
"Sumo Logic Security is a good solution for searching the logs and identifying the issues."
"The tool has key features like operability. It will alert the admins whenever a device is onboarded."
"I have no concerns about the stability of the product. I feel it handles the stress we put on it very well."
"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."
"Sumo Logic is an easy solution to use. You can set it up very quickly, and it includes a lot of training videos."
"We are able to diagnose problems before our customers."
"It helps a lot because we can troubleshoot issues pretty easily."
 

Cons

"The product must improve its UI."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"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."
"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."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"I do not see any areas for improvement at the moment."
"I would like better UI-driven functionality to create alerts and reports. Now, we have to understand the syntax, so it is a little difficult for someone to pick it up without using the manuals. If there was more of a graphical user interface, it would be beneficial."
"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."
"In my opinion, this solution has a steep learning curve and requires practice if users to be able to use this tool very efficiently."
"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."
"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 initial setup is the most stressful, like learning how to use it."
"Sumo Logic needs to make sure integrating solutions are seamless."
"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."
 

Pricing and Cost Advice

"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"Grafana Loki is an open-source solution."
"The cost is less than other paid services like CloudWatch."
"My company doesn't need to pay for the licensing cost of the solution."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"I use the open-source version of the product."
"Grafana Loki is a free, open-source solution."
"We use a free version."
"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."
"Pricing has been cheaper than some of the competing tools, like Splunk."
"Purchasing the solution through the AWS Marketplace is very easy."
"We chose to go through the AWS Marketplace because it makes it a lot easier when we bill our customers. Rather than having to get multiple different sources of information then correlate a monthly bill for our customers, it is just included in the AWS usage charges."
"The product is costly."
"The price scaling comes in a bit expensive."
"The license pricing model is based on the events that are processed through the solution."
"The only limit to the scalability of the product for us is how much we are willing to pay."
