How can I retrieve problem and host name using Zabbix API? - zabbix

Question

I want to retrieve data from Zabbix API using ZabbixAPI.
So I made API JSON like below.
zabbixapi.problem.get(time_from=time_from,
time_till=time_till,
selectHosts = ["host","name"],
sortorder = "DESC",
output = "extend",
monitored = 1)
Result has no host information.
Result is below.
[{'eventid': '401154', 'source': '0', 'object': '0', 'objectid': '18265', 'clock': '1569375897', 'ns': '887610916', 'r_eventid': '0', 'r_clock': '0', 'r_ns': '0', 'correlationid': '0', 'userid': '0', 'name': 'Optical power is low on port 7', 'acknowledged': '0', 'severity': '3', 'suppressed': '0'}, {'eventid': '401456', 'source': '0', 'object': '0', 'objectid': '30714', 'clock': '1569401534', 'ns': '909385820', 'r_eventid': '0', 'r_clock': '0', 'r_ns': '0', 'correlationid': '0', 'userid': '0', 'name': 'Optical power is low on port 33', 'acknowledged': '0', 'severity': '3', 'suppressed': '0'}]
I think "selectHosts" does not work.
How can I get problem with host information?

Answer 1

According to the documentation, problem.get does not have a selectHosts parameter.
Every item of the returned object has a eventid value, you can use it in a event.get call, which supports selectHosts.
Or you can do a single event.get call with selectHosts plus a filter for value = 1, that corresponds to the "Problem" state (see the documentation for the event object)

Answer 2

Using curl.
To get problem event ids:
curl -H "Content-Type: application/json-rpc" -X POST my_zabbix_url -d '{"jsonrpc": "2.0","method": "problem.get","params": {},"auth": "my_token","id": 0}'
To get hosts based on event id:
curl -H "Content-Type: application/json-rpc" -X POST my_zabbix_url -d '{"jsonrpc": "2.0","method": "event.get","params": {"selectHosts": ["host","name"],"output": "extend","select_acknowledges": "extend","objectids": "my_event_object_id","sortfield": ["clock", "eventid"],"sortorder": "DESC"},"auth": "my_token","id": 0}'
