Notes

GETread list /server/omk/opCharts/v2/inventorynReturns a list of all the inventory subconcepts.
GETread list/server/omk/opCharts/v2/inventory/subconcepty

Returns a list of all the inventory ids for the given subconcept.

Paginated.






GETread one /server/omk/opCharts/v2/inventory/idyReturns the details of the requested inventory record.





GETread list /server/omk/opCharts/v2/nodes/node_uuid/inventoryn

Returns a list of all the inventory subconcepts for the given node_uuid.

Paginated.

GETread list /server/omk/opCharts/v2/nodes/node_uuid/inventory/subconcepty

Returns the list of inventory data for the given node_uuid and subconcept.

Paginated.

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: properties=["configuration.customer", "configuration.group"]

By default the nodes UUID is returned by default if no properties are given

page(int) Which page of the requested document to be returned, from 1 .. n, defaults to 1
limit(int) How many results are returned, 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={"configuration.group":"NMIS8","data.index": "196609"} (which is "configuration.group"="NMIS8" AND "data.index"="196609" )

for a string, if it starts with regex: or iregex: then a case-sensitive or case-insensitive regular expression match is used.

eg: filter={"node_name":"iregex:Switch"} to find all the nodes with switch or SWITCH in their name.

sort

1 | -1 : sort the response with id ascending or descending.

redact

0 | 1 : redact the information in configuration.
** works only if you have MongoDB 4.2 and above and set db_use_v42_features => 1 in opCommon.json

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:
