request_body_template
JSON object describing the structure of the request body if arguments must be provided in the body when invoking the action. A JSON string value that takes the form of {parameter-name} must be substituted by user input values encoded as the appropriate JSON type. The following table gives examples where the parameter type is a string, an integer, and an array:
| request_body_template value | parameter value | request body |
|---|---|---|
{"name": "{user-name}"} |
user-name="Joe" |
{"name": "Joe"} |
{"retry count": "{count}"} |
count=10 |
{"retry_count": 10} |
{"domains": "{dns_names}"} |
dns_names=["dns-1", "dns-2"] |
{"domains": ["dns-1", "dns-2"]} |
Only JSON string values that start with a '{' and end with a '}' should be considered for parameter substitutions. A JSON string value such as "{user-name} is the syntax" should be treated as a literal string with no parameter substitution to be performed. Double curly braces '{{' and '}}' are used to escape parameter substitutions, therefore double curly braces must be converted to single curly braces. For example, "{{user-name}}" is converted to the JSON string value "{user-name}". Note that this rule only applies if a JSON string starts with '{{' and ends with '}}'. The following table provides examples of when parameter substitutions must not be performed:
| request_body_template value | request body |
|---|---|
{"name": "{user-name} is bad"} |
{"name": "{user-name} is bad"} |
{"name": "{{user-name}}"} |
{"name": "{user-name}"} |
{"name": "{{user-name}} is bad"} |
{"name": "{{user-name}} is bad"} |
{"name": "{{{{user-name}}}}"} |

action |
array[action] |
Actions that can be performed to remediate the issue that the event instance is reporting. To perform an action, send a request to the |
self |
action
Some automatic remediation actions included in the action link relations are links to the event instance itself, while others are to other public REST APIs. In cases where the action link points to the event instance itself, this property is used in a PATCH request body to trigger a remediation action. The value included as the value of the property depends on each remediation action.

boolean |
Indicates whether the event instance currently has actions that can be performed. |
creation_time |
string |
Timestamp of the event creation. |
history |
array[history] |
History of updates to the event instance. |
index |
integer |
Index of the event. Returned by default. |
last_update_time |
string |
Timestamp of the last update to the event instance. |
log_message |
string |
A formatted text string populated with parameter details. Returned by default. When changing the state of an event instance, include the 'state' property and this property in a PATCH request. The value of this property should describe why the state is changed. |
message |

node |

num_occurrences |
integer |
Number of times the event has repeatedly reported the issue. |
parameters |
array[parameters] |
A list of parameters provided with the EMS event. |
source |
string |
Source |
state |
string |
Indicates the event state. A stateful event tracks the state changes of a system condition and reflects the current system condition. This property and the 'action' property are mutually exclusive in a PATCH request. The state of an event instance can be changed to 'resolved' or 'closed' by sending a PATCH request with this property along with the 'log_message' property describing the reason. An event instance changes its state to 'resolving' only as a result of the user triggering an automatic remediation action, which is done by invoking an action specified in the 'action' link relation. |
stateful |
boolean |
Indicates whether the event is stateful. A stateful event tracks the state changes of a system condition and reflects the current system condition while a stateless event simply reports a certain system condition that has occurred sometime in the past. |
time |
string |
Timestamp of the event. Returned by default. |
uuid |
string |
The UUID that uniquely identifies the event instance. |
