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

"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"We are using Grafana Loki as a database for real-time metrics."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The solution's most valuable feature is its new interface."
"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."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"The ability to write custom alerts is key to information security and compliance."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"Message forwarding through the in-built module."
 

Cons

"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 face some bugs when we install the latest version of Grafana Loki."
"I do not see any areas for improvement at the moment."
"The platform's stability needs improvement."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"I would like to see some kind of visualization included in Graylog."
"Graylog can improve the index rotation as it's quite a complex solution."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
 

Pricing and Cost Advice

"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."

"I use the solution's open-source version. Grafana Loki is a completely free solution for me."

"The cost is less than other paid services like CloudWatch."
"Grafana Loki is a free, open-source solution."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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."
"We're using the Community edition."
"I use the free version of Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."

"Having paid official support is wise for projects."
