Featured Reviews

Nagendra Nekkala. - PeerSpot reviewer
A scalable and stable solution that enables users to see all the event logs in one place
The technical support team is very slow. The support persons do not take prompt action. They take too much time to implement new changes. Even if we tell them that we are not able to get critical logs, they take almost three to four days to provide a resolution. The support is not good.
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.

Quotes from Members

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

Pros

"We check a lot of logs in ArcSight Logger because we're running a massive database platform."
"The most valuable feature is the level of detail that you can see about certain events, even when they do not come up in the console."
"It's a robust, mature product and you can do some really complex operations and analytics."
"ArcSight's robustness is its most valuable feature."
"We have a trigger. So, Logger automatically blocks these IP addresses. We could have Logger put them on a blacklist."
"ArcSight Logger is very stable and useful for customers."
"Some of the most valuable features I really appreciate are the performance, how quick the solution is, and how easy it is to create a query."
"It's a brilliant log collection tool, and it can handle hundreds of thousands of servers in a single shot to ingest the data."
"The tool can be used in multi-cluster environments."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"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."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"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."
 

Cons

"The solution must provide readymade connectors for different applications."
"I had some latency issues for two months. I had to increase our storage capacity significantly to reduce the latency."
"Using the ArcSight Logger dashboard is not particularly intuitive or efficient, so it is important to be trained in its use."
"It would be better if the product is cheaper."
"I think the ArcSight team should try to simplify legacy products for the customers, because that product is not easy to use or to work with. It needs more more competency or appeal to use. We hope Micro Focus is trying to resolve this."
"ArcSight has been sold two or three times, and the quality has decreased."
"You have limited reporting capabilities and I wouldn't choose ArcSight Logger for this purpose."
"ArcSight Logger doesn't have features for user or customer behavior analysis."
"The product must improve its UI."
"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."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The solution's scalability depends on the team managing the Grafana instance."
"I do not see any areas for improvement at the moment."
"The correlation of requests is not simple in Grafana Loki and can be improved."
