API creates the items and zabbix sender fails

[angelhc]

Hello all!
Finally we finish the API configuration to create a lot of items into a defined host, it's so usefull for us cause we generate a lot of data for our apps.
The api creates the items, another script sends the values to the Items but it recives data randomly, for example, we create 112 items and only 70 of them can storage the data, the another ones appears like bad configuration.

Here it's all the sctripts:

API:

from zabbix_api import ZabbixAPI
import logging
import zabbix_api

username='api'
password='apipass'
zapi = zabbix_api.ZabbixAPI('172.xx.xx.xxx','/zabbix/','http')
zapi.login(username,password)
hostapi = zapi.host
#We know the hostid about a query to database
hostid = '10141'

f = open("estadisticas.dat", "r")
while True:
linea = f.readline()
if not linea: break
a = linea
b = "MTM"
description = b + '.' + a[:-1]
key = linea[:-1]
oid = "interfaces.ifTable.ifEntry.ifInOctets.1"
print hostid
print key
print description
zapi.item.create({ 'hostid' : (hostid),'description' : (description),'key_' : key, 'snmp_oid' : oid , 'type' : "2", 'value_type' : "3", 'formula' : "1", 'snmp_community' : "public" })

The API creates all the lines from the estadisticas.dat file to items into zabbix, an example lines:

Estadisticas.dat

SCA_WAS6INT_MSGS_RESPONDIDOS
SCA_WAS6INT_TIEMPO_MIN_RESPUESTA
SCA_WAS6INT_TIEMPO_MAX_RESPUESTA
SCA_WAS6INT_TIEMPO_MED_RESPUESTA
SCA_WAS6INT_NUM_CLI_AHORA
SCA_WAS6INT_NUM_MAX_CLI_START

After this, we runs a script which send data to those items (112):

Send_data.sh

/home/zabbix/bin/zabbix_sender -c /home/zabbix/conf/zabbix_agentd.conf -k SCA_WAS6INT_MSGS_RESPONDIDOS -o 14736
/home/zabbix/bin/zabbix_sender -c /home/zabbix/conf/zabbix_agentd.conf -k SCA_WAS6INT_TIEMPO_MIN_RESPUESTA -o 0.000
/home/zabbix/bin/zabbix_sender -c /home/zabbix/conf/zabbix_agentd.conf -k SCA_WAS6INT_TIEMPO_MAX_RESPUESTA -o 2.696
/home/zabbix/bin/zabbix_sender -c /home/zabbix/conf/zabbix_agentd.conf -k SCA_WAS6INT_TIEMPO_MED_RESPUESTA -o 0.013
/home/zabbix/bin/zabbix_sender -c /home/zabbix/conf/zabbix_agentd.conf -k SCA_WAS6INT_NUM_CLI_AHORA -o 3
/home/zabbix/bin/zabbix_sender -c /home/zabbix/conf/zabbix_agentd.conf -k SCA_WAS6INT_NUM_MAX_CLI_START -o 127214547

The .conf file have the same Hostname than zabbix host configured, and I think is more ellegant to put -c than all the configuration values (and more easy).

The output of the Send_data.sh:
./zabbix_sender -vv -c /home/monaf/zabbix/conf/zabbix_agentd.conf -s bos -k SCA_WAS6INT_NUM_MAX_CLI_START -o 1
zabbix_sender [1778104]: DEBUG: Answer [{
"response":"success",
"info":"Processed 0 Failed 1 Total 1 Seconds spent 0.000019"}]
Info from server: "Processed 0 Failed 1 Total 1 Seconds spent 0.000019"
sent: 1; skipped: 0; total: 1

Of course the firewalls are open to the 10051 and 10050 ports.

Any idea?
Thanks all!

Could it be that the path to zabbix_agentd.conf is incorrect?

/home/zabbix/conf/zabbix_agentd.conf

or

/home/monaf/zabbix/conf/zabbix_agentd.conf


Also check that the Type of information is correct. Numeric (unsigned) or Numeric (float).

Configuration errors will normally be shown in the zabbix_server.log

Also, check the format of Send_data.sh
I had a problem once where the data file had the odd carriage return in the wrong place.

by default zabbix server updates configuration cache every 60 seconds. if you send to a trapper item soon after creating it, server might not be aware of it.
what happens if you wait for a couple of minutes before sending the initial data ?

[angelhc]

MrKen, yes it was a try to hide my production configuration... the path have correct configuration.


richlv, that was our first idea, the server configuration cache updates, but how many time spend the zabbix server to create / update 112 items? cause if we send data to those items each minute maybe the cache update is running and never have all the data...

This is the .conf part where the update is called:

CacheSize=256M
CacheUpdateFrequency=60


It means that each 60 seconds we've an update process and no data can be sending to the items?

Thanks!

[angelhc]

Perfect!
Finally it was the problem, we send data so soon to the items.

Thanks all!
