March 12, 2025 - Fortunately, the good people who develop Prometheus recognize that many teams need to do various things with their data once Prometheus collects it. To help with that task, Prometheus developers offer Alertmanager, an optional tool that you can use alongside Prometheus itself to streamline management of the alerts.

It is mutually exclusive with `telegram_bot_token`. [ telegram_bot_token_file: <string> ] [ webex_api_url: <string> | default = "https://webexapis.com/v1/messages" ] [ mattermost_webhook_url: <secret> ] [ mattermost_webhook_url_file: <string> ] # The default HTTP client configuration [ http_config: <http_config> ] # ResolveTimeout is the default value used by alertmanager if the alert does # not include EndsAt, after this time passes it can declare the alert as resolved if it has not been updated. # This has no impact on alerts from Prometheus, as they always include EndsAt.

The Alertmanager then manages those alerts, including silencing, inhibition, aggregation and sending out notifications via methods such as email, on-call notification systems, and chat platforms.

January 19, 2026 - Alertmanager gives you control over how alerts behave in production. You can set rules for silencing alerts during maintenance, throttle noisy alerts, and define fallback receivers.

July 23, 2025 - Prometheus Alertmanager is a component of the Prometheus suite of tools, and it deals with the alerts produced by core Prometheus monitoring solutions. This is meant to allow for the administration of alerts, allow proper routing to the appropriate ...

January 25, 2026 - Alertmanager transforms raw Prometheus alerts into actionable notifications. By configuring routing rules, grouping, and inhibitions, you can reduce noise and ensure the right people receive the right alerts.

Prometheus's alerting rules are good at figuring what is broken right now, but they are not a fully-fledged notification solution. Another layer is needed to add summarization, notification rate limiting, silencing and alert dependencies on top of the simple alert definitions. In Prometheus's ecosystem, the Alertmanager takes on this role.

The node-exporter service collects hardware and operating system metrics from the host machine, while prometheus scrapes these metrics and stores them. It also exposes a web interface for querying and visualizing the collected data. Finally, alertmanager handles alerts sent by prometheus so they are sent to the configured notification channels.

Prometheus creates and sends alerts to the Alertmanager which then sends notifications out to different receivers based on their labels.

February 26, 2020 - To start, you need to create your alerting rules in Prometheus, and specify under what conditions you want to be alerted (such as when an instance is down). Second, you need to set up Alertmanager, which receives the alerts specified in Prometheus.

June 16, 2025 - Prometheus Alertmanager is a component of the Prometheus ecosystem for handling alerts.

The Alertmanager handles alerts sent by client applications such as the Prometheus server. It takes care of deduplicating, grouping, and routing them to the correct receiver integration such as email, PagerDuty, or OpsGenie.

September 10, 2025 - TL;DR: Set up Prometheus Alertmanager in Kubernetes to automate alerts for issues like app restarts, CPU throttling and memory usage, helping teams proactively maintain reliability and performance.
