Nagios XI vs Sysdig Monitor

Nagios XI monitors servers, network devices, applications and services from a Linux server you manage. It checks configured thresholds, records results and sends notifications. Standard includes more than 90 configuration wizards, auto-discovery, dashboards, performance graphs, an open REST API, automation, configuration rollback and snapshots. Enterprise adds SLA and capacity-planning reports, scheduled reports and pages, business process intelligence, bulk changes and an audit log. Users can be restricted to assigned host and service groups, with authentication options including Active Directory or LDAP over SSL, Microsoft Entra ID single sign-on and Duo two-factor authentication. It is self-hosted on Linux, with virtual machine images for several hypervisors and offline installation on Red Hat and CentOS Stream. A 30-day trial provides unlimited monitoring, Enterprise features and direct support without a credit card. The free plan is limited to 7 nodes or 100 services, whichever comes first. Paid perpetual licenses are priced by monitored nodes: Standard is $2,595.00 once and Enterprise is $4,690.00 once, each shown for 100 nodes.

Sysdig Monitor is a paid monitoring service for distributed production environments. It combines process-level visibility with troubleshooting, alerting, and cost optimization for containers, Kubernetes, Prometheus, cloud services, cloud instances, and serverless resources. Kubernetes views show health and performance, prioritized issues, pod details, live logs, and remediation steps. Its managed Prometheus service offers a scalable data store, automatic service discovery, assisted integration deployment, PromQL support, and Grafana dashboards. Teams can customize dashboards and configure alerts for alert-management systems. Cost analysis uses Kubernetes resource utilization, built-in cost data, and custom metrics. The Sysdig agent gathers predefined host metrics and events and can be extended through configuration files plus monitoring and cloud integrations. Listed integrations cover Apache, Cassandra, Kafka, MySQL, PostgreSQL, AWS, Azure, and Grafana. Security descriptions include audit logging, role-based access, authentication and authorization, agent security, and encryption in transit and at rest. Pricing is on request under host-based or time-series licensing. Platforms are API, Linux, self-hosted, and web.
