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

"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"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."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"Grafana Loki's open-source capability is a significant benefit, with strong indexing performance, cost-effectiveness, and the ability to cross-correlate with Mimir and Tempo for metrics and tracing, making it a robust log management tool."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"LogDNA consolidates all logs into one place, which is super valuable."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
"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."
"We haven't had anything yet that we couldn't do through LogDNA."
 

Cons

"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"I do not see any areas for improvement at the moment."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"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."
"The platform's stability needs improvement."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"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."
"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."
 

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."
"The cost is less than other paid services like CloudWatch."
"I use the open-source version of the product."
"Grafana Loki is a free, open-source solution."
"My company doesn't need to pay for the licensing cost of the solution."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"Grafana Loki is an open-source solution."
