Real-time analysis, easy setup, and open source
We stopped using it for analytics because of its price, and at the moment, we are using it mostly for log centralization. If you use it with high traffic for analytical purposes, as well as for the logs, the infrastructure costs are unbelievable. Graylog is a great product backed by Elasticsearch as the storage and query engine. It is just an interface on top of Elasticsearch and some Elasticsearch management. The indexes that are kept in Elasticsearch are managed by Graylog software. Elasticsearch is a decent product, but it's very infrastructure-heavy. It requires lots of resources, and if you make a mistake with provisioning, you are likely to not get a cluster back. We had a couple of outages like that, and we hated that. So, we ended up over-provisioning resources just to avoid such situations from happening. If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much. That may be my Norwegian take on it, but the engineering resources are expensive. It's better to just provision the infrastructure. Overall, the product is great, and the features are just fine, but the infrastructure cost is what is killing it. The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic. I'm not sure if they can improve the infrastructure cost with the way Elasticsearch is. If they keep using Elasticsearch, maybe there are some opportunities there, or they can support other backends with cheaper storage. They could have a different backend to replace Elasticsearch or do some tweaks to Elasticsearch to reduce the costs. There could be partial parsing of logs or parsing on demand so that when you write data through Graylog to Elasticsearch, it doesn't need to crunch in every detail requiring that much CPU.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Quotes from Members

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

Pros

"Real-time UDP/GELF logging and full text-based searching."
"The product is scalable. The solution is stable."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."
"Graylog is very handy."
"Open source and user friendly."
"Message forwarding through the in-built module."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"The log management has helped to improve my organization."
"The most valuable features of ManageEngine EventLog Analyzer are the number of capabilities, file integration monitoring, web server log collection, and alert configuration."
"The initial setup is straightforward"
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"The user interface is very good."
"The tool's reports show activities."
"I have made use of technical support and am certainly very satisfied with them."
 

Cons

"More customization is always useful."
"With technical support, you are on your own without an enterprise license."
"I would like to see some kind of visualization included in Graylog."
"Dashboards, stream alerts and parsing could be improved."
"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"Graylog can improve the index rotation as it's quite a complex solution."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"I would like to see more detailed reports."
"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
"The first tier of customer service and support is not great."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"The scalability is limited."
"It may not be as easy to use as Splunk."
"The solution should improve on its log capturing capabilities."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
 

Pricing and Cost Advice

"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"It's an open-source solution that can be used free of charge."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"I use the free version of Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"There is a yearly subscription for the solution."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
