Nagios Consulting

Zwiegnet offers deep Nagios expertise for organizations relying on robust, reliable infrastructure monitoring. We support both open-source Nagios Core and commercial Nagios XI, helping you build scalable, proactive monitoring solutions tailored to your Linux and hybrid environments.

Our Nagios services include:

• Implementation & Deployment – Fresh Nagios Core or Nagios XI installations, distributed monitoring setups (parents, satellites), and initial configuration.
• Host & Service Configuration – Template-based definitions, service checks, escalation policies, and dependency mapping.
• Custom Plugins & Scripts – Development of check plugins in Bash, Python, Perl, or other languages for application-specific monitoring.
• Notification & Alerting – Email, SMS, PagerDuty, Slack, or custom webhook integration with intelligent escalation and on-call scheduling.
• High Availability & Redundancy – Failover configurations, distributed monitoring, and load-balanced Nagios instances.
• Performance Optimization – Tuning for large environments, event handler efficiency, and database backend optimization (NDOUtils, MySQL/PostgreSQL).
• Integration – API usage, integration with CM tools (Ansible, Puppet), Grafana dashboards, and event handlers for auto-remediation.
• Reporting & Dashboards – Custom reports, availability SLAs, and enhanced UI with Nagios XI or third-party add-ons.
• Migration & Upgrades – Upgrading from older Nagios versions, migrating from other tools (Zabbix, Icinga, Centreon), or to Nagios XI.
• Troubleshooting & Support – Rapid diagnosis of check failures, performance issues, notification delays, and configuration problems.

Ideal for monitoring servers, network devices, applications, cloud resources, and ensuring uptime for critical services.
