Am I limited on how much data I can store?
No! Nagios Log Server, unlike many of our competitors, allows you to have full access to all of your log data no matter what your license level. We don’t believe in charging you for your own data. We don’t think it’s fair. Your only limitation is the hardware/VM that you put Log Server on, but with Log Server’s ability to quickly scale to your environment, your monitoring needs are always met.

Yes! Manual installation of physical servers is recommended. The server must be RHEL or CentOS. We also distribute Nagios XI as a virtual machine to allow you get it up and running quickly.
What is an instance? How many do I need?
Nagios Log Server systems are based on a clustering model. Each server in the cluster is called an Instance. Adding an Instance to your Log Server cluster allows you to balance server load, create a redundant copy of log event data, and scale Log Server to meet your environment’s needs. Keep your data highly available and redundant with additional Nagios Log Server Instances. Each instance in the cluster shares in the workload of indexing and querying your data. A minimum of 2 instances is recommended to provide redundancy and resiliency.

Yes! Nagios started in the open source community and we hold strong to our roots. Nagios Log Server is free to use for up to 500MB of log data per day. This makes it easy to monitor small environments or to try it in your environment before you buy it!
