Icinga vs Maintenant

Icinga monitors infrastructure and applications, collecting and analyzing data to help teams identify and resolve errors. It covers servers, applications, and network devices across on-premises and cloud environments. Dashboards, filtered and grouped views, and notifications provide visibility, while troubleshooting entry points support root-cause investigation. Teams can extend monitoring with clustering, custom checks, plugins, configurable logic, and distributed environments. Listed integrations include Grafana, InfluxDB, Elastic, Graylog, Ansible, Puppet, Terraform, AWS, Azure, Jira, PagerDuty, and ServiceNow. The free edition supports API automation and Git-based workflows; the pricing FAQ describes a REST API for custom integrations. Icinga says node communication uses TLS/SSL and provides certificate tools. It can monitor certificates, alert as they approach expiry, and verify self-signed certificates using a custom trust store. The product is self-hosted and supports Linux and Windows; official packages cover several Linux distributions and Windows, with some requiring a paid subscription. The free, open source edition includes unlimited hosts and services. Paid support and subscriptions are also available, with support starting at $15,000 a year.

Maintenant is a self-hosted, single-container dashboard for monitoring Docker and Kubernetes infrastructure. It tracks containers, HTTP and TCP endpoints, cron heartbeats, TLS certificates, and CPU, memory, network, and disk metrics. It can discover containers automatically, monitor health and restart loops, and stream logs. Update Intelligence checks OCI registries for image digest changes, while security insights identify exposed ports and risky configurations. The software uses SQLite by default, can be configured to use PostgreSQL, and does not require a separate datastore service. A REST API, real-time SSE streams, and an MCP server connect it to other systems and AI assistants. Community includes webhook and Discord alerts; paid editions add email and Telegram, and Pro adds Slack, Teams, and escalation policies. Community is free forever. Personal costs €149, paid once, including one year of updates; further updates cost 59 € incl. VAT per year. Pro costs €29 a month excluding VAT, or 290 € excluding VAT per year. There is no built-in authentication, so the dashboard and admin API need protection through a reverse proxy and authentication middleware.
