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.

Quotes from Members

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

Pros

"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 solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"The tool can be used in multi-cluster environments."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"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."
"Everything aligns well with improving our organization."
"I can collect logs from various data sources, including hardware."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"We have three or four Logstash servers for high availability."
 

Cons

"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"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."
"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."
"The solution's scalability depends on the team managing the Grafana instance."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"The product needs to improve its compatibility."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"We still have a problem with importing the log system."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
 

Pricing and Cost Advice

"The solution is open source."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
