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."
"The log digestion features from threat intelligence platforms like Recorded Future or Talos are valuable."
"In terms of ArcSight Logger's most valuable feature, it is their scalability. ArcSight's real advantage is its scalability because they have two layers, including the logger layer."
"Our return on investment for implementing ArcSight Logger over the past 12 months has been positive."
"We have a trigger. So, Logger automatically blocks these IP addresses. We could have Logger put them on a blacklist."
"In our country we are a little bit private in terms of solutions, so we are just starting to use the basic data capture. Now some users can start to use additional features that come with Micro Focus ArcSight like user behavior analytics for investigating."
"The most valuable feature is the search capability, which is simple to use."
"The ability to customize the solution in great detail is its most valuable features. We can customize the use cases and also have the ability to do scripting. We can personalize our dashboard as well. The scalability the solution offers is quite impressive."
"The log collection feature is good and the solution is easily understandable. v"
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"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."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
 

Cons

"I would rate the technical support only 5 out of 10. The technical support is not satisfactory."
"The solution must provide readymade connectors for different applications."
"The integration with other systems could be improved."
"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."
"It's not a new product and is a bit complex. So, it requires a person dedicated to working on it and to know about it in and out. It is a huge product, and the search operation is a bit complicated for a new user or someone who has not used it for long. So for that person, it becomes a bit difficult."
"Using the ArcSight Logger dashboard is not particularly intuitive or efficient, so it is important to be trained in its use."
"The console in older versions is not user-friendly."
"They are migrating to Splunk because ArcSight Logger doesn't have those features for user or customer behavior analysis."
"The platform's stability needs improvement."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"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."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"The product must improve its UI."
"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."
 

Pricing and Cost Advice

"Pricing is reasonable compared to similar tools on the market. They offer perpetual licenses."
"We have a lifetime license, so we don't pay a monthly fee."
"It's not cheap at all as it's a big product and has been in the market for quite some time now."
"ArcSight is an expensive solution."
"I rate the product’s pricing a seven out of ten, where one is inexpensive, and ten is expensive."
"I would rate the product a seven out of ten since it's an enterprise product."
"The pricing is quite harsh."
"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."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"The solution is open source."
"The cost is less than other paid services like CloudWatch."
"I use the open-source version of the product."
"My company doesn't need to pay for the licensing cost of the solution."
"Grafana Loki is a free, open-source solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
