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.

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

Pros

"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 log collection feature is good and the solution is easily understandable. v"
"Grafana Loki is easy to monitor and detect errors."
"We are using Grafana Loki as a database for real-time metrics."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"I can collect logs from various data sources, including hardware."
"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."
"Everything aligns well with improving our organization."
"We have three or four Logstash servers for high availability."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
 

Cons

"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."
"My main concern is the recommended production-grade setup. They suggest using tools like Tanka or Jsonnet. They should simplify the process to increase adoption."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"The platform's stability needs improvement."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"We face some bugs when we install the latest version of Grafana Loki."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"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."
"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."
"We still have a problem with importing the log system."
