### Summary This PR makes a handful of updates to the APM app documentation: - [x] **Alerts tab, workflow, and grouping** - Rewrote most of our [alerting documentation](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/apm-alerts.html#apm-alert-view-active) to explain the new granularity level of alerts, address new alert names, and explain the different ways to view active alerts. - Updated the [Services](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/services.html) documentation to describe the alert badge and link to alerting docs. - _Closes https://github.com/elastic/observability-docs/issues/2887_ - _Closes https://github.com/elastic/observability-docs/issues/2888_ - _Closes https://github.com/elastic/observability-docs/issues/2878_ - [x] **Infrastructure tab** - Added a new [top-level page](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/infrastructure.html) explaining what this page is useful for. - _Closes https://github.com/elastic/observability-docs/issues/2892_ - [x] **Log views and correlation** - Added a new [top-level page ](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/logs.html)that links to our log correlation docs. - Updated our [transaction documentation](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/transactions.html#transaction-trace-sample) with new information and a link to our log correlation docs. - _Closes https://github.com/elastic/observability-docs/issues/2891_ - [x] **New AWS Lambda metrics** - Most of the new charts have tooltips explaining what the charts do. I updated the screenshot and added some additional information to the [overview](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/apm-lambda.html) to highlight some of the new features of this page. - _Closes https://github.com/elastic/observability-docs/issues/2890_ - [x] **New screenshots** - I updated any screenshots I noticed were outdated while working on the above content.

The APM app allows you to define **rules** to detect complex conditions within your APM data
|
|
and trigger built-in **actions** when those conditions are met.
|
|
|
|
The following **rules** are supported:
|
|
|
|
* **Threshold rule**:
|
|
Alert when the latency or failed transaction rate is abnormal.
|
|
Threshold rules can be as broad or as granular as you'd like, enabling you to define exactly when you want to be alerted--whether that's at the environment level, service name level, transaction type level, and/or transaction name level.
|
|
* **Anomaly rule**:
|
|
Alert when either the latency of a service is anomalous. Anomaly rules can be set at the environment level, service level, and/or transaction type level.
|
|
* **Error count rule**:
|
|
Alert when the number of errors in a service exceeds a defined threshold. Error count rules can be set at the environment level, service level, and error group level.
|
|
|

|
|
|
|
Below, we'll walk through the creation of two APM rules.
|
|
|
|
For a complete walkthrough of the **Create rule** flyout panel, including detailed information on each configurable property,
|
|
see Kibana's <<create-edit-rules,create and edit rules>>.

|
|
=== Example: create a latency anomaly rule
|
|
|
|
Latency anomaly rules trigger when the latency of a service is abnormal.
|
|
Because some parts of an application are more important than others, and have a different
|
|
tolerance for latency, we'll target a specific transaction within a service.
|
|
|
|
Before continuing, identify the service name, transaction type, and environment that you'd like to create a latency anomaly rule for.
|
|
This guide will create an alert for all services based on the following criteria:
|
|
|
|
* Service: `{your_service.name}`
|
|
* Transaction: `{your_transaction.name}`
|
|
* Environment: `{your_service.environment}`
|
|
* Severity level: critical
|
|
* Check every five minutes
|
|
* Send an alert to a Slack channel when the rule status changes
|
|
|
|
From any page in the APM app, select **Alerts and rules** > **Create anomaly rule**.
|
|
Change the name of the rule, but do not edit the tags.
|
|
|
|
Based on the criteria above, define the following rule details:
|
|
|
|
* **Service** - `{your_service.name}`
|
|
* **Type** - `{your_transaction.name}`
|
|
* **Environment** - `{your_service.environment}`
|
|
* **Has anomaly with severity** - `critical`
|
|
* **Check every** - `5 minutes`
|
|
|
|
Next, add a connector type. Multiple connectors can be selected, but in this example we're interested in Slack.
|
|
Select **Slack** > **Create a connector**.
|
|
Enter a name for the connector,
|
|
and paste your Slack webhook URL.
|
|
See Slack's webhook documentation if you need to create one.
|
|
|
|
A default message is provided as a starting point for your alert.
|
|
You can use the https://mustache.github.io/[Mustache] template syntax, i.e., `{{variable}}`
|
|
to pass additional alert values at the time a condition is detected to an action.
|
|
A list of available variables can be accessed by selecting the
|
|
**add variable** button image:apm/images/add-variable.png[add variable button].
|
|
|
|
Click **Save**. Your rule has been created and is now active!
|
|
|

[[apm-create-error-alert]]
|
|
=== Example: create an error count threshold alert
|
|
|
|
The error count threshold alert triggers when the number of errors in a service exceeds a defined threshold.
|
|
Because some errors are more important than others, this guide will focus a specific error group ID.
|
|
|
|
Before continuing, identify the service name, environment name, and error group ID that you'd like to create a latency anomaly rule for.
|
|
The easiest way to find an error group ID is to select the service that you're interested in and navigating to the **Errors** tab.
|
|
|
|
This guide will create an alert for an error group ID based on the following criteria:
|
|
|
|
* Service: `{your_service.name}`
|
|
* Environment: `{your_service.environment}`
|
|
* Error Grouping Key: `{your_error.ID}`
|
|
* Error rate is above 25 errors for the last five minutes
|
|
* Group alerts by `service.name` and `service.environment`
|
|
* Check every 1 minute
|
|
* Send the alert via email to the site reliability team
|
|
|
|
From any page in the APM app, select **Alerts and rules** > **Create error count rule**.
|
|
Change the name of the alert, but do not edit the tags.
|
|
|
|
Based on the criteria above, define the following rule details:
|
|
|
|
* **Service**: `{your_service.name}`
|
|
* **Environment**: `{your_service.environment}`
|
|
* **Error Grouping Key**: `{your_error.ID}`
|
|
* **Is above** - `25 errors`
|
|
* **For the last** - `5 minutes`
|
|
* **Group alerts by** - `service.name` `service.environment`
|
|
* **Check every** - `1 minute`
|
|
|
|
Select the **Email** connector and click **Create a connector**.
|
|
Fill out the required details: sender, host, port, etc., and click **save**.
|
|
|

A default message is provided as a starting point for your alert.

=== View active alerts
|
|
|
|
Active alerts are displayed and grouped in multiple ways in the APM app.

[[apm-alert-view-group]]
|
|
==== View alerts by service group
|
|
|
|
If you're using the <<service-groups,service groups>> feature, you can view alerts by service group.
|
|
From the service group overview page, click the red alert indicator to open the **Alerts** tab with a predefined filter that matches the filter used when creating the service group.
