 Netdata allows you to send custom notifications to any endpoint you choose.
 
-To configure custom notifications, you will need to customize `health_alarm_notify.conf`. You can look at the other senders in `/usr/libexec/netdata/plugins.d/alarm-notify.sh` for examples of how to modify the `custom_sender()` function in `health_alarm_notify.conf`. Ensure you follow the instructions of changing any configuration file to [persist your configuration](../../../docs/configuration-guide.md#persist-my-configuration).

+# Dynatrace
+
+Dynatrace allows you to receive notifications using their Events REST API.
+
+See [the Dynatrace documentation](https://www.dynatrace.com/support/help/extend-dynatrace/dynatrace-api/environment-api/events/post-event/) about POSTing an event in the Events API for more details.
+
+
+
+You need:
+
+1.  Dynatrace Server. You can use the same on all your Netdata servers but make sure the server is network visible from your Netdata hosts.
+The Dynatrace server should be with protocol prefixed (`http://` or `https://`). For example: `https://monitor.example.com`
+This is a required parameter.
+2.  API Token. Generate a secure access API token that enables access to your Dynatrace monitoring data via the REST-based API.
+Generate a Dynatrace API authentication token. On your Dynatrace server, go to **Settings** --> **Integration** --> **Dynatrace API** --> **Generate token**.
+See [Dynatrace API - Authentication](https://www.dynatrace.com/support/help/extend-dynatrace/dynatrace-api/basics/dynatrace-api-authentication/) for more details.
+This is a required parameter.
+3.  API Space. This is the URL part of the page you have access in order to generate the API Token. For example, the URL
+    for a generated API token might look like:
+    `https://monitor.illumineit.com/e/2a93fe0e-4cd5-469a-9d0d-1a064235cfce/#settings/integration/apikeys;gf=all` In that
+    case, my space is _2a93fe0e-4cd5-469a-9d0d-1a064235cfce_ This is a required parameter.
+4. Generate a Server Tag. On your Dynatrace Server, go to **Settings** --> **Tags** --> **Manually applied tags** and create the Tag.
+The Netdata alarm is sent as a Dynatrace Event to be correlated with all those hosts tagged with this Tag you have created.
+This is a required parameter.
+5. Specify the Dynatrace event. This can be one of `CUSTOM_INFO`, `CUSTOM_ANNOTATION`, `CUSTOM_CONFIGURATION`, and `CUSTOM_DEPLOYMENT`. 
+The default value is `CUSTOM_INFO`.
+This is a required parameter.
+6. Specify the annotation type. This is the source of the Dynatrace event. Put whatever it fits you, for example, 
+_Netdata Alarm_, which is also the default value.

+# Matrix
+
+Send notifications to [Matrix](https://matrix.org/) network rooms.
+
+The requirements for this notification method are:
+
+1.  The url of the homeserver (`https://homeserver:port`).
+2.  Credentials for connecting to the homeserver, in the form of a valid access token for your account (or for a
+    dedicated notification account). These tokens usually don't expire.
+3.  The room ids that you want to sent the notification to.
+
+To obtain the access token, you can use the following `curl` command:
+
+```bash
+curl -XPOST -d '{"type":"m.login.password", "user":"example", "password":"wordpass"}' "https://homeserver:8448/_matrix/client/r0/login"
+```
+
+The room ids are unique identifiers and can be obtained from the room settings in a Matrix client (e.g. Riot). Their
+format is `!uniqueid:homeserver`.
+
+Multiple room ids can be defined by separating with a space character.
+
+Detailed information about the Matrix client API is available at the [official
+site](https://matrix.org/docs/guides/client-server.html).

+# Send notifications to Opsgenie
+
+[Opsgenie](https://www.atlassian.com/software/opsgenie) is an alerting and incident response tool. It is designed to
+group and filter alarms, build custom routing rules for on-call teams, and correlate deployments and commits to
+incidents.
+
+The first step is to create a [Netdata integration](https://docs.opsgenie.com/docs/api-integration) in the
+[Opsgenie](https://www.atlassian.com/software/opsgenie) dashboard. After this, you need to edit
+`health_alarm_notify.conf` on your system, by running the following from your [config
+directory](/docs/configure/nodes.md):
+ 
+```bash
+./edit-config health_alarm_notify.conf
+```
+
+Change the variable `OPSGENIE_API_KEY` with the API key you got from Opsgenie.
+
+```
+SEND_OPSGENIE="YES"
+
+# Api key
+# Default Opsgenie APi
+OPSGENIE_API_KEY="11111111-2222-3333-4444-555555555555"
+```
+
+Changes to `health_alarm_notify.conf` do not require a Netdata restart. You can test your Opsgenie notifications
+configuration by issuing the commands, replacing `ROLE` with your preferred role:
+
+```sh
+# become user netdata
+sudo su -s /bin/bash netdata
+
+# send a test alarm
+/usr/libexec/netdata/plugins.d/alarm-notify.sh test ROLE
+```
+
+If everything works, you'll see alarms in your Opsgenie platform:
+
+![Example alarm notifications in
+Opsgenie](https://user-images.githubusercontent.com/49162938/92184518-f725f900-ee40-11ea-9afa-e7c639c72206.png)
+
+If sending the test notifications fails, you can look in `/var/log/netdata/error.log` to find the relevant error
+message:
+
+```log
+2020-09-03 23:07:00: alarm-notify.sh: ERROR: failed to send opsgenie notification for: hades test.chart.test_alarm is CRITICAL, with HTTP error code 401.

+
+[Prowl](https://www.prowlapp.com/) is a push notification service for iOS devices.  Netdata
+supports delivering notifications to iOS devices through Prowl.
+
+Because of how Netdata integrates with Prowl, there is a hard limit of
+at most 1000 notifications per hour (starting from the first notification
+sent).  Any alerts beyond the first thousand in an hour will be dropped.
+
+Warning messages will be sent with the 'High' priority, critical messages
+will be sent with the 'Emergency' priority, and all other messages will
+be sent with the normal priority.  Opening the notification's associated
+URL will take you to the Netdata dashboard of the system that issued
+the alert, directly to the chart that it triggered on.
+
+## configuration
+
+To use this, you will need a Prowl API key, which can be requested through
+the Prowl website after registering.
+
+Once you have an API key, simply specify that as a recipient for Prowl
+notifications.

+# Send notifications to StackPulse
+
+[StackPulse](https://stackpulse.com/) is a software-as-a-service platform for site reliability engineering.
+It helps SREs, DevOps Engineers and Software Developers reduce toil and alert fatigue while improving reliability of 
+software services by managing, analyzing and automating incident response activities.
+
+Sending Netdata alarm notifications to StackPulse allows you to create smart automated response workflows 
+(StackPulse playbooks) that will help you drive down your MTTD and MTTR by performing any of the following:
+
+-   Enriching the incident with data from multiple sources
+-   Performing triage actions and analyzing their results
+-   Orchestrating incident management and notification flows
+-   Performing automatic and semi-automatic remediation actions
+-   Analyzing incident data and remediation patterns to improve reliability of your services
+
+To send the notification you need:
+
+1.  Create a Netdata integration in the `StackPulse Administration Portal`, and copy the `Endpoint` URL.
+
+![Creating a Netdata integration in StackPulse](https://user-images.githubusercontent.com/49162938/93023348-d9455a80-f5dd-11ea-8e05-67d07dce93e4.png)
+
+2.  On your node, navigate to `/etc/netdata/` and run the following command:
+
+```sh
+$ ./edit-config health_alarm_notify.conf
+```
+
+3.  Set the `STACKPULSE_WEBHOOK` variable to `Endpoint` URL you copied earlier:
+
+```
+SEND_STACKPULSE="YES"
+STACKPULSE_WEBHOOK="https://hooks.stackpulse.io/v1/webhooks/YOUR_UNIQUE_ID"
+```
+
+4.  Now [restart Netdata](/docs/getting-started.md#start-stop-and-restart-netdata). When your node creates an alarm, you
+    can see the associated notification on your StackPulse Administration Portal 
+
+## React to alarms with playbooks
+
+StackPulse allow users to create `Playbooks` giving additional information about events that happen in specific 
+scenarios. For example, you could create a Playbook that responds to a "low disk space" alarm by compressing and 
+cleaning up storage partitions with dynamic data.
+

+### Create Playbooks for Netdata alarms
+
+To create a Playbook, you need to access the StackPulse Administration Portal. After the initial setup, you need to
+access the **TRIGGER** tab to define the scenarios used to trigger the event. The following variables are available:
+
+-  `Hostname`: The host that generated the event.
+-  `Chart`: The name of the chart.
+-  `OldValue` : The previous value of the alarm.
+-  `Value`: The current value of the alarm.
+-  `Units` : The units of the value.
+-  `OldStatus` : The previous status: REMOVED, UNINITIALIZED, UNDEFINED, CLEAR, WARNING, CRITICAL.
+-  `State`: The current alarm  status, the acceptable values are the same of `OldStatus`.
+-  `Alarm` : The name of the alarm, as given in Netdata's health.d entries.
+-  `Date` : The timestamp this event occurred.
+-  `Duration` : The duration in seconds of the previous alarm state.
+-  `NonClearDuration` : The total duration in seconds this is/was non-clear.
+-  `Description` : A short description of the alarm copied from the alarm definition.
+-  `CalcExpression` : The expression that was evaluated to trigger the alarm.
+-  `CalcParamValues` : The values of the parameters in the expression, at the time of the evaluation.
+-  `TotalWarnings` : Total number of alarms in WARNING state.
+-  `TotalCritical` : Total number of alarms in CRITICAL state.
+-  `ID` : The unique id of the alarm that generated this event.
+
+For more details how to create a scenario, take a look at the [StackPulse documentation](https://docs.stackpulse.io).
