Gyeeta vs Icinga

Gyeeta is a free, open-source observability tool for Linux that runs in a self-hosted setup. It uses eBPF and kernel statistics to monitor hosts, services, and processes without application instrumentation. For TCP services, it reports query rates, latency, network throughput, active connections, and process resource use. Automatic discovery finds TCP services, clients, and dependencies without code changes or configuration inputs. Algorithms can identify service degradation or contention and suggest a probable cause. You can inspect results in a Web UI or query REST APIs, including queries spanning multiple hosts, with JSON responses. Alert notifications support email, Slack, PagerDuty, and webhooks. Documentation says data remains in-house. Installation is available through shell scripts, Helm charts, Docker containers, rpm or deb packages, and tar packages. The architecture documentation describes monitoring tens of thousands of hosts with one central server and intermediate servers. Gyeeta supports x86_64 Linux hosts with kernel 4.4 or newer.

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.
