Zabbix trend.get output multiple values

[lkthomas]

Folks, I am using pyzabbix as a wrapper to speed up my development, I think it's more or less the same as JSON because I don't think it's doing anything on the back to further manipulate output data.

from pyzabbix import ZabbixAPI
from datetime import datetime
import time

# The hostname at which the Zabbix web interface is available
ZABBIX_SERVER = 'http://zabbix.com'

zapi = ZabbixAPI(ZABBIX_SERVER)

# Login to the Zabbix API
zapi.login('zabbixreadonly', 'zabbixreadonly')

item_id = '34265'

# Create a time range
time_till = time.mktime(datetime.now().timetuple())
time_from = time_till - 60 * 60 * 40 # 40 hours

# Query item's history (integer) data
trend = zapi.trend.get(itemids=[item_id],
#sortfield="clock",
#sortorder="ASC",
time_from=time_from,
time_till=time_till,
output=["clock", "value_avg"],
)




print (trend)

This is something I don't understand, my aim is to get 40 hours average, min and max value, how come I got tons of value_avg instead of one value?
