Change who owns alerting. Prometheus, Zabbix and Grafana each have their ground. Nightingale argues for one thing only: the alerting layer should belong to a tool built for it.

Before it changes anything that already exists, it shows you the diff. ### 01Investigate It pulls the event, the rule, runs the rule’s query over the window, checks neighbouring hosts and muting rules, and hands back an evidence chain. The call is still yours. ### 02Cut the noise Which rules are the noisiest and which have never fired, in one question. For the ones that recur on a schedule, ask whether they are candidates for self-healing. ### 03Change configuration Changes to existing objects take two turns: the tool returns a confirmation card first and writes only after you confirm. A proposal expires in 30 minutes, applies once, and is refused if someone edited the object meanwhile. There are no delete tools.

The Nightingale way Rules live in the UI, scoped by business group. ### Signs it is time to switch * Rules must be maintained by teams who are not SREs * Someone has to be phoned at 3am, not just webhooked * The data is no longer all in Prometheus [Read the full comparison](https://n9e.github.io/comparisons/prometheus-alertmanager.md) [ →](https://n9e.github.io/comparisons/prometheus-alertmanager.md) Migration guide[From Prometheus + Alertmanager →](https://n9e.github.io/docs/migration/from-alertmanager.md) 02 ## Zabbix Their way Collect everything with its own agents, then alert on that. The Nightingale way Alert on the stores you already fill; collect only where nothing does. ### Signs it is time to switch * Telemetry already lives in Prometheus, VictoriaMetrics or ElasticSearch * Kubernetes and cloud services outnumber network gear * You maintain two collection stacks to get one alert [Read the full comparison](https://n9e.github.io/comparisons/zabbix.md) [ →](https://n9e.github.io/comparisons/zabbix.md) Migration guide[From Zabbix →](https://n9e.github.io/docs/migration/from-zabbix.md) 03 ## Grafana Alerting Their way Alerting as a module inside the visualization platform. The Nightingale way Alerting as the whole product; chart wherever you like. ### Signs it is time to switch * Alert volume has outgrown a panel-level rule model * You need event pipelines, subscriptions or self-healing * On-call people need phone and SMS, not only contact points [Read the full comparison](https://n9e.github.io/comparisons/grafana-alerting.md) [ →](https://n9e.github.io/comparisons/grafana-alerting.md) Migration guide[From Grafana Alerting →](https://n9e.github.io/docs/migration/from-grafana-alerting.md) ## Nothing has to be switched off Nightingale reads the storage you already run, so the switch is a parallel run, not a cut-over. 1. 1 ### Point it at your storage Register Prometheus, VictoriaMetrics or ElasticSearch as a data source. Nothing in the collection path changes. 2. 2 ### Move the rules across The migration guides map every entry of an alertmanager.yml or a Grafana alert rule onto a Nightingale object, and say plainly which ones have no equivalent. 3. 3 ### Run both, cut over by channel Compare what fires each day, switch one notification channel at a time, and back out of any stage in about a minute. [Coexistence and rollback plan →](https://n9e.github.io/docs/migration/coexistence.md) ## Questions people ask before switching Can I keep Grafana? Yes, and it is the most common setup: chart in Grafana, alert in Nightingale. A Nightingale dashboard can also embed a Grafana dashboard by URL. Do I have to replace Prometheus? No. Prometheus keeps scraping and storing; Nightingale takes over rules, noise reduction and routing on top of it, so nothing has to move. Can Alertmanager rules be migrated? Rules, routes, silences and receivers each map onto a Nightingale object. The migration guide takes an alertmanager.yml apart entry by entry and lists the few that have no equivalent. Can Nightingale read Zabbix data? No. Moving from Zabbix is a rebuild: hosts become targets, templates become integrations, triggers become rules, and Categraf takes over collection. Zabbix never has to stop while you do it. When should I not switch? At moderate scale, with a GitOps-comfortable team and a rule count you can hold in your head, Prometheus + Alertmanager is enough. For network gear and SNMP-first estates, Zabbix is still home ground. ## Not sure? Run both. Nightingale reads the storage you already have. Installing it changes nothing about the alerting you run today.
