Event Management Service – Filtering¶

When reading events (using GET All /events api), all events are filtered for a tenant whose token is used for making a request. In addition, you can supply one or more of the following field names in the filter queries and any of your custom field which has filterable property set to true :

• entityId
• typeId
• correlationId
• timestamp

When reading events of Standard Type or any of its custom child type, you can use below additional fields in the filter query :

• acknowledged
• source
• severity
• code

Wildcards are not supported. Timestamps must be in the following format: 2018-01-01T00:00:00.00Z

When a filter has no matches, the response will be empty.

Filter functions¶

Function eq (equals)¶

{
  "name": "MyMotor"
}

or

{
  "name": {
    "eq": "MyMotor"
  }
}

Function in¶

The function in is very similar to equals, but instead matching to one value, it checks an array of values, and matches for any of them.

{
  "name": {
    "in": {
      "value": ["MyMotor", "MyEngine"]
    }
  }
}

Function endsWith¶

{
  "name": {
    "endsWith": "Motor"
  }
}

Function startsWith¶

{
  "name": {
    "startsWith": "My"
  }
}

Function before¶

{
  "timestamp": {
    "before": "2018-01-01T00:00:00.00Z"
  }
}

{
  "timestamp": {
    "after": "2018-01-01T00:00:00.00Z"

    "between": "[2018-01-01T00:00:00.00Z, 2018-01-31T00:00:00.00Z)"
  }
}

    "name": {
