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."
"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."
"ArcSight Logger is very stable and useful for customers."
"It's an efficient solution."
"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."
"ArcSight's robustness is its most valuable feature."
"The most valuable feature is the search capability, which is simple to use."
"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."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The log collection feature is good and the solution is easily understandable. v"
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"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."
 

Cons

"ArcSight Logger doesn't have features for user or customer behavior analysis."
"The console in older versions is not user-friendly."
"The platform is quite expensive. They should reduce its cost."
"I had some latency issues for two months. I had to increase our storage capacity significantly to reduce the latency."
"The speed of Logger indexing and searching for certain bugs for some queries that we provide could be improved. It can handle a huge number of logs but it can be improved."
"The initial setup was a little bit complex."
"You have limited reporting capabilities and I wouldn't choose ArcSight Logger for this purpose."
"They are migrating to Splunk because ArcSight Logger doesn't have those features for user or customer behavior analysis."
"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."
"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."
"I do not see any areas for improvement at the moment."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"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."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
 

Pricing and Cost Advice

"The pricing is quite harsh."
"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."
"It's not cheap at all as it's a big product and has been in the market for quite some time now."
"We have a lifetime license, so we don't pay a monthly fee."
"ArcSight is an expensive solution."
"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."
"Pricing is reasonable compared to similar tools on the market. They offer perpetual licenses."
"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."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"My company doesn't need to pay for the licensing cost of the solution."
"We use a free version."
"The cost is less than other paid services like CloudWatch."
"You can use the free version of Grafana Loki on-premises."
