The most valuable feature of the solution is that Nagios Log Server sends me the data needed for monitoring the data centers of my customers. For my company, it is also a tool that is affordable enough to be deployed on the customer side.

One of the most valuable features is the dashboard because the UI was effective and easy to use.

The alert systems are good as well.

We had no failovers and had high availability.

We can search the queries fast as well in Nagios Log Server.

What I like about Nagios Log Server is its simplicity in collecting logs from servers. It provides an easy way to identify errors and spot issues, making troubleshooting more efficient.

It's easy to add the client host to Log Server, and we can manage everything easily. We can see the logs easily through the web dashboard, and there are different charts available for viewing. 

Also, we can, using a search tool, we can query for events. If something happens in the server, we can query and trigger alerts. We can trigger alerts if some query happened in the server.

The product is scalable. 

A great feature of the solution involves its internal portal. The architecture is based on the open source and I find it very easy to use. Their community team developed many parts that I can use with my customers. The monitoring I have done makes configuring easier.

The most important feature involves the pricing, which I found to be quite affordable when it comes to the setting by us of one of our product services.
