[gduchate]

Hello

I am new to ZABBIX and I am trying to query some problem's data using the API, I managed to get a list of current problems as below, however I need some help on how to find or correlate these problem with the host they are coming from. The output from the problem get is as follow:
thanks

After further investigation I attempted to query triggers with the objectid returned by the problem. I manage to get a reply but it still does not contain the hostname related to the problem I am looking for. The following is the example:

request
{
"params": {
"triggerids": [
"16005"
],
"selectHosts": [
"hostid",
"name"
]
},
"id": 1561655547,
"jsonrpc": "2.0",
"method": "trigger.get",
"auth": "b5dcd8c47dfdf6d26c4ae266dbe3ae1b"
}

Hello

I tried the recommended request to get the hosts for a trigger but the response still does not include the host. This is what I tried using Zabbix 4.0

Request

{
"params": {
"triggerids": [
"16005"
],
"selectHosts": "extend",
"output": "extend"
},
"id": 310502771,
"jsonrpc": "2.0",
"method": "trigger.get",
"auth": "60d7457bcc03cd05690855507e613e51"
}
