Keep your storage.
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.

AI is part of the process, not an add-on

It reads your alerts, rules and metrics, so answers come from your data rather than the model’s memory. Before it changes anything that already exists, it shows you the diff.

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.

01

Prometheus + Alertmanager

Their way

Rules live in YAML and ship through GitOps.

The Nightingale way

Rules live in the UI, scoped by business group.

Where it shines

Prometheus remains one of the best time-series foundations available, and Alertmanager’s grouping and silencing model is genuinely clean. At moderate scale, with a GitOps-comfortable team and a rule count you can hold in your head, the pair is enough and adds no components.

When Nightingale fits better

Nightingale earns its place when rules must be maintained by teams who are not SREs, when permissions need to follow business groups, when someone has to be phoned at 3am, or when the data is not all in Prometheus.

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

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.

Where it shines

Two decades of work show in traditional IT monitoring: network gear, SNMP, agent-based collection and auto-discovery are its home ground, and the hiring pool knows it well.

When Nightingale fits better

If your telemetry already lives in Prometheus, VictoriaMetrics or ElasticSearch, Nightingale reads it directly instead of asking you to pour it into a second collection stack.

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

Why did this host go offline?
Nightingale AI
The agent stopped reporting 3 minutes ago, but the host answers ping and its neighbours are healthy. That points to the Categraf process exiting, not the host going down.

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.

Where it shines

Grafana is the visualization standard and its dashboard ecosystem has no real substitute. If alert volume is modest and Grafana is already in place, its built-in alerting is one system fewer to run.

When Nightingale fits better

Nightingale puts everything into the alerting side: event pipelines, subscriptions, self-healing. The two are not exclusive — plenty of users chart in Grafana and alert in Nightingale.

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

Of 40 panels, 3 query metrics that no longer exist, and 2 show an abnormal trend in the last hour: connections and slow_queries.

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.

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. Nightingale does not store time series. Prometheus keeps scraping and storing; Nightingale takes over rules, noise reduction and routing on top of it.

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.
