“In regard to log based alerts, using NLS provides great advantages generally for our users, especially using the several different type of options for alert thresholds. The default query for failed user logins enables us to detect network intrusions, which is extremely useful.”

Stand-Alone

Find the right plan for you with our Log Server Plan Calculator

Nagios does not recommend single-instance Log Server deployments, but we do offer them to those who understand the trade-off. Single-Instance deployments do not offer redundancy or failover in the event of system failures due to the nature of Log Server’s shard-and-cluster process.
