Request Modifiers (query parameters)
The properties request modifier tells opCharts which properties you would like listed, query limits the requested resources to only those that match all criteria given. This collection can paginated, it is also limited to 25 results by default (this could be subject to change in future opCharts versions) use the limit query parameter to request more nodes
Not all requests will use all request modifiers.
Query Parameter | Possible Values |
|---|---|
properties | Array of property names. If provided only the properties specified will be returned (instead of the whole document). eg: By default the nodes UUID is returned by default if no properties are given |
page | (int) Which page of the requested document to return, defaults to 1 |
limit | (int) How many results to return, defaults to 25 |
filter | Array of key=value pairs, but coded in an array. Applied to the list of results in the order they are given. If an application key is provided that will be applied first. eg: filter={"level":"Normal"} |
sort | -1 | 1 : sort the response with id ascending or descending. |
Examples of how to use the request modifiers can be found in the response blocks below. In general, the queries will look something like this:
GET of opcharts/v2/events for List
