Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.

A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

Quotes from Members

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

Pros

"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."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"Grafana Loki's open-source capability is a significant benefit, with strong indexing performance, cost-effectiveness, and the ability to cross-correlate with Mimir and Tempo for metrics and tracing, making it a robust log management tool."
"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."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"Grafana Loki is easy to monitor and detect errors."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"The most valuable feature is that we can create our own connectors for any application, and NetWitness provides the training and tools to do it."
"RSA NetWitness is a SIEM and real-time network traffic solution that collects logs and packets, applies a set of alerting, reporting, and analysis rules on them, and thus provides the enterprise with full visibility of the networks and activities of the systems."
"The solution is really scalable for the high-end power, enterprise customer."
"Integration is exceedingly minimal, since its project development is much easier than that of LogRythm or IBM."
"Setting up NetWitness is straightforward. There are multiple connectors, including standard and specialized connectors. One purpose of the connectors is the enhanced capability integrate the custom applications. NetWitness comes with E6 appliances and application images that we use for the initial configurations and for the OS stack information. From there, you can consider the correlation rules, integrate the different log sources, and easily create correlation rules and backlog reports."
"Performance and reporting are very good."
"The software is scalable to whatever is required, and you can also put a lot of resources in the cloud."
 

Cons

"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"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 Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"The product must improve its UI."
"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 implementation needs assistance."
"An area for improvement would be better automation and more inbuilt use cases."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions."
"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"I am not happy with the RSA support. Sometimes they can be really annoying because it takes so long to get the support that you need."
"I believe that integrating the solution with other products such as Oracle would be beneficial."
"More customizability is required, which is something that they need to improve on."
"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
 

Pricing and Cost Advice

"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"My company doesn't need to pay for the licensing cost of the solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"Grafana Loki is a free, open-source solution."
"The cost is less than other paid services like CloudWatch."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"We use a free version."
"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"It is cheap."
"Our license is for one year."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"We have yearly licensing costs. The license fee can be based on the volume of EPS. Some organizations may have, as a gentlemanly gesture, 10,000 EPS and get a 3,000 EPS license but actually use 5,000 EPS."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"It’s cheaper to run virtual machines in a VMware environment."
