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

"The machine learning is a good feature."
"We haven't had any crashes or bugs. It is stable."
"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 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."
"I am impressed with the product's ability to pick up logs. It also has UEBA which has reduced the time to take charge of the events."
"Our return on investment for implementing ArcSight Logger over the past 12 months has been positive."
"The technical support team is good...It is a scalable solution."
"ArcSight Logger is very stable and useful for customers."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The tool can be used in multi-cluster environments."
"We are using Grafana Loki as a database for real-time metrics."
"The log collection feature is good and the solution is easily understandable. v"
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"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."
 

Cons

"I would rate the technical support only 5 out of 10. The technical support is not satisfactory."
"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."
"The console in older versions is not user-friendly."
"I would like to see better scheduling in the next release of this solution."
"The solution must provide readymade connectors for different applications."
"The solution should make it possible to integrate network analysis features."
"The platform is quite expensive. They should reduce its cost."
"They are migrating to Splunk because ArcSight Logger doesn't have those features for user or customer behavior analysis."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"I do not see any areas for improvement at the moment."
"We face some bugs when we install the latest version of Grafana Loki."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"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 correlation of requests is not simple in Grafana Loki and can be improved."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
 

Pricing and Cost Advice

"I would rate the product a seven out of ten since it's an enterprise product."
"The pricing is quite harsh."
"ArcSight is an expensive solution."
"We have a lifetime license, so we don't pay a monthly fee."
"I rate the product’s pricing a seven out of ten, where one is inexpensive, and ten is expensive."
"Pricing is reasonable compared to similar tools on the market. They offer perpetual licenses."
"ArcSight Logger is very expensive compared to their competitors, but when we talk to the customer and explain what the features are and how we can scale, they understand. Still, ArcSight is more expensive than the competition."
"It's not cheap at all as it's a big product and has been in the market for quite some time now."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"The cost is less than other paid services like CloudWatch."
"The solution is open source."
"We use a free version."
"Grafana Loki is a free, open-source solution."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"I use the open-source version of the product."
