Cheaper ways to solve the same problem
What you would be giving up
Icinga is most often brought in for an it team wanting unlimited-scale open source monitoring with no per-host licence fee, running standard linux distributions, an organisation on rhel or sles that wants officially packaged icinga builds via the repository subscription rather than building from source, a team wanting an sla-backed vendor support relationship rather than relying on community forums for a production monitoring system, a company already invested in prometheus and grafana wanting to add host and service-level alerting from a compatible open source tool. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Icinga is broadly right and the question is cost, the Icinga pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Networking category lists everything the directory holds, and best networking tools ranks them.
Icinga runs on linux, web. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
