Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.

Log analysis has become clearer and faster but visualization and extensibility still need work
The problem was with the complexity and the cost to add extensions. We found this very expensive to buy another version with additional features. I think that Graylog Enterprise does not have customizable dashboards. I did not see them in Graylog Enterprise because most of the time we used the open source free version, which is limited. I think Graylog Enterprise should improve some things that they have in the paid version and perhaps provide users with a menu that gives examples of parsing logs and draws graphics so that people do not need to improve another system such as Grafana. This would be interesting. When it comes to functionalities, I found the log management in Graylog Enterprise acceptable. It is very simple to use and to collect logs. It has support for different protocols and different ports, and the sidecar is easy to use. However, in visualization, I think it needs to be much better.

Pros

"Grafana Loki's open-source capability is a significant benefit, and Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"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 of Grafana Loki is the dashboards which are really simple to create."
"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."
"The product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Message forwarding through the in-built module."
"I like the correlation and the alerting."
"Real-time UDP/GELF logging and full text-based searching."
"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."
"Troubleshooting is straightforward with Graylog Enterprise."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The solution's most valuable feature is its new interface."
 

Cons

"The product must improve its UI."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"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 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."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"The solution's scalability depends on the team managing the Grafana instance."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"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."
"The problem was with the complexity and the cost to add extensions."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"Lacks sufficient documentation."
"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."

"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."
"Having paid official support is wise for projects."

"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."
