9 
+      The PushoverAgent receives and collects events and sends them via push notification to a user/group.
10 
+
11 
+      **You need a Pushover API Token:** [https://pushover.net/apps/build](https://pushover.net/apps/build)
12 
+
13 
+      **You must provide** a `message` or `text` key that will contain the body of the notification. This can come from an event or be set as a default. Pushover API has a `512` Character Limit including `title`. `message` will be truncated.
14 
+
15 
+      * `token`: your application's API token
16 
+      * `user`: the user or group key (not e-mail address).
17 
+      * `expected_receive_period_in_days`:  is maximum number of days that you would expect to pass between events being received by this agent.
18 
+
19 
+      Your event can provide any of the following optional parameters or you can provide defaults:
20 
+
21 
+      * `device` - your user's device name to send the message directly to that device, rather than all of the user's devices
22 
+      * `title` or `subject` - your notifications's title
23 
+      * `url` - a supplementary URL to show with your message - `512` Character Limit
24 
+      * `url_title` - a title for your supplementary URL, otherwise just the URL is shown - `100` Character Limit
25 
+      * `priority` - send as `-1` to always send as a quiet notification, `0` is default, `1` to display as high-priority and bypass the user's quiet hours, or `2` for emergency priority: [Please read Pushover Docs on Emergency Priority](https://pushover.net/api#priority)
26 
+      * `sound` - the name of one of the sounds supported by device clients to override the user's default sound choice. [See PushOver docs for sound options.](https://pushover.net/api#sounds)
27 
+      * `retry` - Requred for emergency priority - Specifies how often (in seconds) the Pushover servers will send the same notification to the user. Minimum value: `30`
28 
+      * `expire` - Requred for emergency priority - Specifies how many seconds your notification will continue to be retried for (every retry seconds). Maximum value: `86400`
29 
+
30 
+      Your event can also pass along a timestamp parameter:
31 
+
32 
+      * `timestamp` - a [Unix timestamp](https://en.wikipedia.org/wiki/Unix_time) of your message's date and time to display to the user, rather than the time your message is received by the Pushover API.
