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

"We are using Grafana Loki as a database for real-time metrics."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"Grafana Loki is easy to monitor and detect errors."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"We have three or four Logstash servers for high availability."
"Everything aligns well with improving our organization."
"The transformation means we ship the logs in the way that we want them to be presented in Kibana, which is the main function we use Logstash for."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"I can collect logs from various data sources, including hardware."
 

Cons

"I do not see any areas for improvement at the moment."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"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."
"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."
"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."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"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."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"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."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"We still have a problem with importing the log system."
