Manage events using gRPC API methods

On this page:

Get all events within a given interval

{
    "method": "AxxonSoft.bl.events.EventHistoryService.ReadEvents",
    "data": {
        "range": {
            "begin_time": "20200225T125548.340",
            "end_time": "20200225T130548.341"
        },
        "limit": 30,
        "offset": 0,
		"descending": false
    }
}

If descending = false, then the events in the response will be sorted by time in ascending order. If descending = true, then the events will be sorted in descending order.

Get events by filter

The following parameters can be set as a filter:

type − type of event; the actual types of events are given in the AxxonSoft\bl\events.proto file;
subjects − subject of event (server, device, archive, detector, etc.);
values − exact value of event;
texts − brief description of event.

Get events about status change of a specific camera:

{
    "method": "AxxonSoft.bl.events.EventHistoryService.ReadEvents",
    "data": {
        "range": {
            "begin_time": "20200225T152806.572",
            "end_time": "20200225T153806.572"
        },
        "filters": {
            "filters": [
                {
                    "type": "ET_IpDeviceStateChangedEvent",
                    "subjects": "hosts/Server1/DeviceIpint.10"
                }
            ]
        },
        "limit": 300,
        "offset": 0,
		"descending": false
    }
}

Get events about disconnection of all cameras::

{
    "method": "AxxonSoft.bl.events.EventHistoryService.ReadEvents",
    "data": {
        "range": {
            "begin_time": "20200226T074425.274",
            "end_time": "20200226T075425.274"
        },
        "filters": {
            "filters": [
                {
                    "type": "ET_IpDeviceStateChangedEvent",
                    "values": "IPDS_DISCONNECTED"
                }
            ]
        },
        "limit": 300,
        "offset": 0,
		"descending": false
    }
}

                    "texts": "tracker"
                }
            ]
