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.

It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

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."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The tool can be used in multi-cluster environments."
"LogDNA consolidates all logs into one place, which is super valuable."
"We haven't had anything yet that we couldn't do through LogDNA."
"With LogDNA, which brings all the logs together in an interleaved stream, it allows us to take a transaction and relate it to other contextual events making the gathering of evidence for auditors and our internal RCA much more productive."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
 

Cons

"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"The platform's stability needs improvement."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"I do not see any areas for improvement at the moment."
"The product must improve its UI."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"No ability to encapsulate a query or a filter, and communicate or share that among the team."
"Scalability could be improved; we are using it through the IBM cloud deployment and on some of the data centers that are very heavily used, there is a significant lag in the event stream, sometimes 10, 15 minutes behind, which makes the RCA impossible."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."
