programmitically usage of maintenance.update in C#, .NET 8 (ZABBIX version 6.0)

[Nerd24]

Hello there,

maybe I'm right here. I've written a small application, which communicates with a ZABBIX server on version 6.0 by using
C# in .NET core 8 with JSON.

This includes to list all stored hosts, creating a maintenance and updating a maintenance.

Unlike the last one everything works fine. And this is the point, where I'm now out of ideas what to do.

Based on the API documentation => https://www.zabbix.com/documentation...tenance/update
I need the property timeperiods to say when an active maintenance shall be terminated earlier or later, however, ZABBIX reports:

{
    "jsonrpc": "2.0",
        "error": {
         "code": -32600,
         "message": "Invalid request.",
         "data": "Invalid parameter \"/\": unexpected parameter \"timeperiods\"."
     }
"id": 3
}

So, I'm getting the information, that the given request with timeperiods as property won't work. When I'm running the JSON pattern without this property, then the command returns the expected result, like:

{
    "jsonrpc": "2.0",
    "result": {
        "maintenanceids": [
            "12"
        ]
   },
    "id": 1
}​

but the active maintenance is still running until the defined timestamp has been reached.

The skeleton for maintenance.update in C# looks like this:

    public class MaintenanceUpdate {
        public String? jsonrpc;
        public String? method;
        public Parameters? @params;
        public TimePeriod? timeperiods;                 // This might be wrong for the API?
        public String? auth;
        public double id;

        public class Parameters {
            public String? maintenanceid;
            public List<HostSettings>? hosts;
        }

        public class HostSettings {
            public String? hostid;
        }

        public class TimePeriod {
            public int period;
            public int timeperiod_type;
            public uint start_date;
            public int start_time;
            public int every;
            public int dayofweek;
            public int day;
            public int month;
        }
    }
}​

I'm using this class pattern above here:

using(StreamWriter sw = new StreamWriter(httpWebRequest.GetRequestStream())) {
                MaintenanceUpdate mUpdate = new MaintenanceUpdate() {
                                jsonrpc = "2.0",
                                method = "maintenance.update",
                                id = 3,
                                auth = < top secret key here :-) >,
                                @params = new MaintenanceUpdate.Parameters() {
                                    maintenanceid = hostToUse.maintenanceid,
                                    hosts = new List<MaintenanceUpdate.HostSettings>() {
                                        new MaintenanceUpdate.HostSettings() {
                                            hostid = hostID.ToString()
                                        }
                                    }
                                },
                                timeperiods = new MaintenanceUpdate.TimePeriod() {
                                    period = 0
                                }
                };

                sw.Write(JsonConvert.SerializeObject(mUpdate));
}

MaintenanceUpdateResponse? responseMaintenanceUpdate;
httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using(StreamReader sr = new StreamReader(httpResponse.GetResponseStream())) {
                String result = sr.ReadToEnd();
                Console.WriteLine(result);                      // <-- prints the error message [...]unexpected parameter \"timeperiods\"."[...]
                responseMaintenanceUpdate = JsonConvert.DeserializeObject<MaintenanceUpdateResponse>(result);
}​

So, the JSON format for maintenance.update looks like this:

{
    "jsonrpc": "2.0",
    "method": "maintenance.update",
    "params": {
        "maintenanceid": "12",
        "hosts": [
            {
                "hostid": "< ID of the host >"
            }
        ]
       },
      "timeperiods": {
           "period": 0,
           "timeperiod_type": 0,
            "start_date": 0,
            "start_time": 0,
            "every": 0,
            "dayofweek": 0,
            "day": 0,
            "month": 0
      },
"auth": "< super secret key :-) >",
"id": 3
}

Do I miss something? Is there maybe an another way to handle this?
Thanks in advise. (:

I am not much of a programmer, but shouldn't timeperiods be part of parameters? Currently seems it falls out of "params: {}" and thus you get errors...
example is here... https://www.zabbix.com/documentation...tenance/create
