+
+Specify the classification of the alarm or template.
+
+Class can be used to indicate the broader area of the system that the alarm applies to. For example, under the general `Database` class, you can group together alarms that operate on various database systems, like `MySQL`, `CockroachDB`, `CouchDB` etc. Example:
+

+class: Database

+<summary>Netdata's stock alarms use the following `class` attributes by default, but feel free to adjust for your own requirements.</summary>

+| Certificates | Certificates monitoring related |

+| Containers | Container related alerts (e.g. docker instances) |
+| Database | Database systems (e.g. MySQL, Postgress, etc) |
+| Data Sharing | Used to group together alerts for data sharing applications |
+| DHCP | Alerts for dhcp related services |
+| DNS | Alerts for dns related services |
+| Kubernetes | Alerts for kubernetes nodes monitoring |
+| KV Storage | Key-Value pairs services alerts (e.g. memcached) |
+| Linux | Services specific to Linux (e.g. systemd) |
+| Messaging | Alerts for message passing services (e.g. vernemq) |
+| Netdata | Internal Netdata components monitoring |
+| Other | Use as a general class of alerts |
+| Power Supply | Alerts from power supply related services (e.g. apcupsd) |
+| Search engine | Alerts for search services (e.g. elasticsearch) |
+| Storage | Class for alerts dealing with storage services (storage devices typically live under `System`) |

+If an alarm configuration is missing the `class` line, its value will default to `Unknown`.
+
+#### Alarm line `component`
+
+Component can be used to narrow down what the previous `class` value specifies for each alarm or template. Continuing from the previous example, `component` might include `MySQL`, `CockroachDB`, `MongoDB`, all under the same `Database` classification. Example:
+
+```yaml
+component: MySQL
+```
+As with the `class` line, if `component` is missing from the configuration, its value will default to `Unknown`.
+
+#### Alarm line `type`
+
+This indicates the type of error (or general problem area) that the alarm or template applies to. For example, `Latency` can be used for alarms that trigger on latency issues in network interfaces, web servers, or database systems. Example:
+
+```yaml
+type: Latency
+```
+
+`type` will also (as with `class` and `component`) default to `Unknown` if the line is missing from the alarm configuration.

+# Microsoft Teams
+
+This is what you will get:
+![image](https://user-images.githubusercontent.com/1122372/92710359-0385e680-f358-11ea-8c52-f366a4fb57dd.png)
+
+You need:
+
+1. The **incoming webhook URL** as given by Microsoft Teams. You can use the same on all your Netdata servers (or you can have multiple if you like - your decision).
+2. One or more channels to post the messages to.
+
+In Microsoft Teams the channel name is encoded in the URI after `/IncomingWebhook/` (for clarity the marked with `[]` in the following example): `https://outlook.office.com/webhook/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX@XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/IncomingWebhook/[XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX`
+
+You have to replace the encoded channel name by the placeholder `CHANNEL` in `MSTEAMS_WEBHOOK_URL`. The placeholder `CHANNEL` will be replaced by the actual encoded channel name before sending the notification. This makes it possible to publish to several channels in the same team.
+
+The encoded channel name must then be added to `DEFAULT_RECIPIENTS_MSTEAMS` or to one of the specific variables `role_recipients_msteams[]`. **At least one channel is mandatory for `DEFAULT_RECIPIENTS_MSTEAMS`.**
+
+Set the webhook and the recipients in `/etc/netdata/health_alarm_notify.conf` (to edit it on your system run `/etc/netdata/edit-config health_alarm_notify.conf`), like this:
+
+```
+SEND_MSTEAMS="YES"
+
+MSTEAMS_WEBHOOK_URL="https://outlook.office.com/webhook/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX@XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/IncomingWebhook/CHANNEL/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
+
+DEFAULT_RECIPIENT_MSTEAMS="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+```
+
+You can define multiple recipients by listing the encoded channel names like this: `XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY`.
+This example will send the alarm to the two channels specified by their encoded channel names.
+
+You can give different recipients per **role** using these (in the same file):
+
+```
+role_recipients_msteams[sysadmin]="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+role_recipients_msteams[dba]="YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
+role_recipients_msteams[webmaster]="ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ"
+```
