LogDNA is great for all your apps to log activity. Not much more to say about it. It does what it sets out to do. Everyone in our company uses our app so it's nice when someone is having an issue and we need to dig deeper into what they were doing and LogDNA helps in those scenarios.
SumoLogic is a fantastic log aggregator and analysis tool, a fine alternative to Splunk. Searching is powerful and mostly intuitive and results come fast. If you have application logs in clusters or Kubernetes pods that lose their logs every time they're restarted, Sumo is the solution for you
Log Aggregation and uploading. The architecture for Sumo Logic makes a great deal of sense and works very well.
Automated analysis. It still impresses me how well a newly uploaded log can be broken into intelligent parts, then searched and sorted using their tools.
Dashboards. It might not be what YOU will need as an IT admin, but you can give access to these dashboards easily to business users who love that kind of stuff. Most other types of (monitoring / alerting) tools, for no apparent reason, lack this feature.
Reporting, monitoring, and graphing. Given, you need to have useful log generation for an application or service as a prerequisite for sumo logic to be able to gain use, once it has it is an amazingly powerful tool.
The colors are ugly, both the dark and light theme. Needs better contrast and color combinations. It's also weird that dark mode has white dropdown menus on the filters.
It's really easy to use and powerful. But at a few times, the UI may feel sluggish, which is a bit expected, since it's displaying live stream of heavy data.
Sumo Logic is very powerful but definitely requires some configuration work to get the most out of it. You can get a certification related to this, but it is definitely not something you can just throw together.
It is very very good. They are responsive and very helpful. They also take the time to walk you through the issues you are having. But honestly, it is so straightforward that you rarely need to get support from their team. They are very helpful when you do need their support though.
I would give this rating because I attended a free Sumo Logic training at a WeWork in Chicago. I found the training very useful, and I learned a lot of features that I was not aware of before I went to the training. I like the idea that SumoLogic provides free training seminars. I am certified in level1, and I plan on certifying to level2.
I was satisfied with the implementation, as at the time, it was the best way to implement the product with the available feature sets in Sumo Logic. User creation and management became more of an issue during continued use, instead of it being an issue related to deploying the product in our environment.
I have not used any other software but I have gone through demos of others and LogDNA gave us everything we needed at a fair price and with a great UI on the back end. It was not even a question of which software to choose. They are a great team.
We had used Splunk previously. Sumo Logic defeats them when it comes to cost, including the costs that would normally come with supporting/managing/patching/upgrading your own infrastructure and storage. Those were wins, but especially the real-time CDN integrations due to Sumo Logic's collaborations with other vendors. We had spoken to Logentries and discovered that many of the cons we found with Sumo Logic seemed to have been resolved in their product. Their pitfall was that, at the time, Logentries did not have the ability to get real-time log ingestion from our CDN. They said they had a solution, which was scripted, but we had not evaluated/tested. Logentries also did not have a User / RBAC REST API, and are nowhere near the level of compliance that Sumo Logic had (https://www.sumologic.com/press/2015-02-19/sumo-logic-successfully-completes-pci-data-security-stand...). In the end, I believe Logentries and Sumo Logic would be two good vendors to get involved in a bake-off
