Nagios Log Server provides real-time log analysis, custom dashboards, and high-performance storage with perpetual licensing and no per-GB fees.
Aggregate every source. Syslog, Windows Event Logs, flat files, and application logs from servers, network devices, and cloud platforms in one repository.
Search in plain English. The AI Query Assistant turns natural-language prompts into Lucene queries, so anyone can search logs.
Process logs in real time. OpenSearch-based indexing surfaces threats and performance issues as events arrive.
Speak every protocol. Native support for syslog (TCP/UDP/TLS), JSON, and custom formats with extensible parsing.
Skip the parser-writing. Built-in parsers handle common formats, with custom field extraction when you need it.
Keep history searchable. Configurable retention, compression, and automatic archiving for compliance and forensics.
Build dashboards for every team. Role-based views with dashlets, charts, and live log streams.
Alert on what matters. Trigger on log patterns, error conditions, or thresholds, with automated escalation.
Start with templates. Default dashboards and a community library get you running on day one.
Route notifications anywhere. Email, SNMP traps, or Nagios XI for SMS and third-party integrations.
Correlate across sources. Build queries that join data from different systems to surface threats early.
Feed metrics into Nagios XI. Turn log data into passive checks for capacity planning and SLA tracking.
Centralized logging is the backbone of nearly every compliance framework. Log Server gives you the controls, retention, and evidence trail to support your program.
Prove compliance with every framework. Scheduled, exportable reports for PCI DSS, HIPAA, SOX, GDPR, and FISMA audits.
Meet log retention mandates. Configurable retention and automatic archiving keep historical logs intact as long as regulators require.
Produce audit-ready evidence on demand. Forensic search, field extraction, and timeline reconstruction answer auditor questions fast.
Enforce least-privilege access. Role-based, multi-tenant permissions control who can view, search, or export each log source.
Protect log integrity in transit. TLS-encrypted syslog satisfies data-in-motion controls under PCI DSS and HIPAA.
Maintain a complete chain of custody. Every user action, config change, and export is logged for a defensible audit trail.
Schedule a personalized demo and discover how Nagios Log Server can transform your infrastructure monitoring.
“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.”

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.
