Problem zabbix sender

[adeptus24]

Hello all,

I wrote this problem in the specific subforum for my native language, but I think I will obtain more support writing it here, sorry for my English.

We have a problem when register values of an item. We have to collect values from a database once a day, send it with the zabbix_sender and only the difference register with the above value.

In a script collect the value of a database informix.

Run the zabbix_sender with the key for the value to be sent zabbix server.

Here I show the configuration of the item, log the zabbix_sender and log server in "debug 4".

script log

[2016-06-03 10:30:02] tifxqms1shm_repba - sender: -k tamLlogs -o 14131200 info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000108" sent: 1; skipped: 0; total: 1

Item conf

 Type: "Zabbix trapper"
 Key: "tamLlogs"
 Type of information: "Numeric (unsigned)"
 Data type: "Decimal"
 Units:
 Use custom multiplier:
 Store value: "Delta (simple change)"

 23650:20160603:103002.278 trapper #4 [processed data in 0.000698 sec, waiting for connection]

Now comes the strange problem, the first time you run does not record any value, but if you run a second time, third, fourth, etc ... records each and every one of the values sent by the zabbix_sender.

Does anyone have any idea that might be? It is the only item we are having problems.

That's because you store value as "Delta (simple change)". The first value Zabbix can store is the difference between the second value you sent and the first value you sent.

First, thanks for your reply, the problem is that there are values in the table, one fails the first time that sent with zabbix_sender every day, the second time not fail, only the first time it runs every day, but I only want to run once a day.

Do you restart Zabbix server every day?

Yes, to make a copy of mysql database.

Zabbix server needs at least two values since restart to store something as Delta (simple change) or Delta (change per second). Save value as is and create calculated item to calculate change.

Thanks so much... one question more... we have updated from 2.0 version, in this version we don't have this problem, the server was reset just as you reboot now.

Sorry, I don't understand your question.

Sorry, I don't understand your question.

Sorry, there was a problem when sending the message in the post, we have updated to version 2.4.8 from a 2.0.6 version, in 2.0.6 version we didn't have this problem and had the same configuration item, it is a change of the 2.4 version? we make a copy of the database in a way that does not have to restart the zabbix_server.

Thank you so much for all!!!
