Hello,

How can I create time based events in Kibana when I post something to elastic search?

How and What I am posting:

Function takes Json input in a loop.

def file\_shipper(host\_facts):  
 ES\_HOST = "exampleelasticsearch"  
 es = Elasticsearch(host=ES\_HOST)  
 index = "test"

es\_index = IndicesClient(es)  
if es\_index.exists(index):  
 print(f"{index} already exists, skipping creation")  
else:  
 es\_index.create(index)  
 print(f"{index} is created")

req = requests.post(f'https://{host}/test/test',data=host\_facts, verify=False)  
print(req)

host\_facts looks like this

{  
"\_index": "test",  
"\_type": "test",  
"\_id": "AWjom6txnKgMFUMColSE",  
"\_score": 1,  
"\_source": {  
"ip": "10.40.220.134",  
"hostname": "ARISTA-01-L3",  
"vendor": "Arista",  
"model": "DCS-7160-48YC6-F",  
"os\_version": "4.20.11M-10590868.42011M",  
"uptime": 4243232,  
"cpu": {  
"0": {  
"%usage": 14.1  
}  
},  
"latency": {  
"AWS-END-POINT": {  
"RTT": 17.562,  
"packetloss": 0  
},  
"SG2-END-POINT": {  
"RTT": 0.33,  
"packetloss": 0  
}  
},  
"@timestamp" : October 24th 2018, 10:20:45.67  
}  
}  
Question:  
on kibana I'm not able to create timebased events, it works if I uncheck time based events. How can I populate timestamp correctly, so that I can create timebased events?

Thanks in advance!

Kibana requires the timefield to actual have a date field-type in Elasticsearch.

Ensure that your Elasticsearch index uses a Date data-type ([https://www.elastic.co/guide/en/elasticsearch/reference/current/date.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/date.html)) for that `@timestamp`.

So verify your mapping is correct there in Elasticsearch. If not, you will have to set the mapping explicitly on your index, before adding documents.
