# ManageEngine OpManager

EvoHub receives OpManager alarms through a notification profile of type **Invoke a Webhook**. Each alarm opens an EvoHub alert; when OpManager sends the same alarm as **Clear**, the alert resolves.

## Set it up

:::steps
### Create the integration
In EvoHub, go to **On-Call → Integrations → + Add Integration**, choose **ManageEngine OpManager**, pick an **Escalation Policy** and click **Create Integration**. Copy the **Webhook URL**.
### Create the notification profile
In OpManager, go to **Settings → Notifications → Notification Profiles → Add** and choose **Invoke a Webhook**. Set the **Request URL** to your webhook URL, the method to `POST` and the body type to **Raw** / **JSON**, and paste the body below.
### Choose the criteria
Select the alarm severities that should page and also the **clear** criterion. Without it OpManager never tells EvoHub the alarm has cleared.
### Associate devices
Apply the profile to the devices or groups to monitor.
:::

```json
{"alarm_id":"$alarmid","entity":"$entity","device":"$displayName","category":"$category","severity":"$stringseverity","message":"$message","event_type":"$eventType","ip":"$DeviceField(ipAddress)","time":"$strModTime"}
```

**Test Action** sends the variables without values. EvoHub answers with success and opens no alert.

## What EvoHub reads

| EvoHub alert | Taken from |
| --- | --- |
| Title | `device` and `event_type`, for example *core-sw-01 – CPU Utilization*. |
| Description | `message`. |
| Labels | `category`, `ip`, `device`, `alarm_id`, `entity`, `time`, `severity`. |

### Severity

| OpManager severity | EvoHub severity |
| --- | --- |
| Critical, Service Down | critical |
| Trouble | high |
| Attention | medium |
| Clear | resolves the alert |

## Resolve and deduplication

An alarm is identified by its `entity` (the device and monitor). A repeat while the alert is open is recorded as **Retriggered**; a **Clear** for the same entity resolves it.
