Featured Reviews

Volodymyr Bondarchuk - PeerSpot reviewer
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.
Syarul Idzuddin Adzmi - PeerSpot reviewer
A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"There are new features like that pilot code and things like that for profiling."
"We are using Grafana Loki as a database for real-time metrics."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
"The product is scalable."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
 

Cons

"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"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."
"We face some bugs when we install the latest version of Grafana Loki."
"The solution's scalability depends on the team managing the Grafana instance."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"The support could be better."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
