Quotes from Members

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

Pros

"Grafana Loki is easy to monitor and detect errors."
"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."
"The tool can be used in multi-cluster environments."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"We are using Grafana Loki as a database for real-time metrics."
"There are new features like that pilot code and things like that for profiling."
"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 most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"Everything aligns well with improving our organization."
"I can collect logs from various data sources, including hardware."
"We have three or four Logstash servers for high availability."
 

Cons

"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The product must improve its UI."
"We face some bugs when we install the latest version of Grafana Loki."
"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."
"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."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"The solution's scalability depends on the team managing the Grafana instance."
"The product needs to improve its compatibility."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"We still have a problem with importing the log system."
"Almost all the research can be very bad. We still have a problem with importing the log system."
 

Pricing and Cost Advice

"The cost is less than other paid services like CloudWatch."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"Grafana Loki is an open-source solution."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"You can use the free version of Grafana Loki on-premises."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"We use a free version."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
