# Alerts with Alert Manager
Configure alerts with Grafana's native Alert manager for DuploCloud's AOS
Grafana's native Alert manager is used for alerting within the DuploCloud Advanced Observability Suite (AOS). DuploCloud's AOS includes a default set of alerts based on best practices and compliance standards. Custom alerting can also be set up to meet your unique needs based on log strings, metrics, etc.
## Default Alerts
When you enable AOS, a set of alerts is automatically available in Grafana. These alerts cover common health and performance issues for Linux nodes and Kubernetes clusters, helping you monitor critical infrastructure without extra setup.
The default alerts include:
Linux Node AlertsLinux Filesystem AlertsKubernetes Application AlertsKubernetes Resource AlertsKubernetes Storage Alerts
These alerts are provided automatically in Grafana for AOS. Any additional alerts beyond these categories must be manually created.
## Configuring Custom Alerts
Any alerting beyond the default node and Kubernetes integrations must be created manually. For example, you might add alerts based on:
* Application-specific error logs (e.g., HTTP 500 spikes).
* Business KPIs (e.g., queue depth, transaction rates).
* Service-level metrics such as latency or availability.
These types of alerts can be defined directly in Grafana to suit your organization’s needs. To create or manage them, follow these steps:
1. From the DuploCloud Portal, navigate to one of the following dashboards:
* Admin AOS Dashboard: **Administrator** → **Observability** → **Advanced** → **Dashboard**
* Tenant AOS Dashboard: **Observability** → **Advanced** → **Dashboard**
2. Click the **Alert** icon ( ) on the right end of the **Observability** header.
3. The Grafana **Alert rules** page displays, allowing you to view, add, delete, or modify alerts. For detailed instructions, see the [Grafana alert documentation](https://grafana.com/docs/grafana/latest/alerting/alerting-rules/).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.duplocloud.com/docs/automation-platform/diagnostics-overview/advanced-observability-suite/alerts-with-alert-manager.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
