Featured Reviews

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.
Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Quotes from Members

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

Pros

"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."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The tool can be used in multi-cluster environments."
"Grafana Loki is easy to monitor and detect errors."
"We are using Grafana Loki as a database for real-time metrics."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"Open source and user friendly."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"I am very proud of how very stable the solution is."
"Message forwarding through the in-built module."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
 

Cons

"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."
"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."
"The product must improve its UI."
"I do not see any areas for improvement at the moment."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"Dashboards, stream alerts and parsing could be improved."
"I would like to see some kind of visualization included in Graylog."
"Lacks sufficient documentation."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
 

Pricing and Cost Advice

"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"I use the open-source version of the product."
"We use a free version."
"Grafana Loki is an open-source solution."
"My company doesn't need to pay for the licensing cost of the solution."
"The cost is less than other paid services like CloudWatch."
"The solution is open source."
"Having paid official support is wise for projects."
"It's an open-source solution that can be used free of charge."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
