Pros

Surest mean to effectively run diagnostics on your servers to root out any faults that may be causing unexpected hitches. With so much flexibility, you can get just anything. The search feature works pretty fast giving you reports whenever you need info.

It has a rather simplified interface that makes you just think of a mobile app. You can use the dashboard to manage logs of various applications. This lets you see areas where you need to make adjustments for improvement. In addition, you can analyze every log and mine all useful data.

It integrates seamlessly with cloud providers and you get the most done with AWS right by your side. Also, if you're stuck at any point, you can reach out to customer care and have your issue addressed in good time.

Cons

The live-mode feature should be made such that when you start the tool, you are automatically switched on because it's easy to forget to switch it on every time you're starting it. It would be such a good thing.

Pros

Sumo logic is very flexible and easy to integrate with different cloud providers. But it's specifically easy to work with AWS.
I had to create an IAM user and provide the credentials to sumo logic collectors which started pulling in data from S3 buckets immediately.
Option to generate variety of Dashboards from real-time streaming data.

Cons

I didn't like the tabular interface. you have to scroll all the way to the right to find your tabs.
It could be have been made more user friendly.

Pros

I like the fact that it looks like a mobile app, it is very simple to use, setting up your dashboard is very simple, real-time monitoring is reliable and being able to add a different filter to every running job, gives makes monitoring very simple

Cons

the "live mode" button sometimes you open up the app and you forget to switch it on, it would be better if the app is always on live mode

Pros

It is very navigable and offers perfect ui which is very intuitive. You can write any type of query , sumo logic will have answer to that type. We can easily search and export. You can configure it the way you want it to behave and give you the readings in the real time. You can know the properties of a running job from all the jobs on the dashboard which is a great plus from the similar softwares.

Cons

Sometimes it is very hard to reach customer support , you may have to wait till someone can come to your rescue on an issue.
