Problem with 1.6.1 Zabbix Trapper item having Text type

[stan.vasiljev]

Zabbix Trapper item having Text type works perfectly in Zabbix v. 1.4.4.
But after upgrade to 1.6.1 Zabbix shows empty values for items, which have Text type of information. It's strange, because it still works for items, which have Str type of information, even after upgrade to 1.6.1.

For example:
1. Zabbix Trapper Item "strHostTraps" have Str type of info. I run this command:
/usr/sbin/zabbix_sender -z192.168.0.1 -p10051 -s"sHostTrapper" -k"strHostTraps" -o"proxy test".
Info from server: "Processed 1 Failed 0 Total 1 Seconds spent 0.026671"
sent: 1; skipped: 0; total: 1

And I can see this value in front-end:
Timestamp Value
2008.Nov.07 13:04:50 proxy test

1. When Zabbix Trapper Item "txtHostTraps" have Text type of info. And after I run this command:
/usr/sbin/zabbix_sender -z192.168.0.1 -p10051 -s"sHostTrapper" -k"txtHostTraps" -o"proxy test".
Info from server: "Processed 1 Failed 0 Total 1 Seconds spent 0.026671"
sent: 1; skipped: 0; total: 1
Sorry, but I can't see this value in front-end - there are empty space:
Timestamp Value
2008.Nov.07 13:05:15
It is strange, because in front-end for this text item I can see older values, which were been perfectly sent and inserted by zabbix 1.4.4. But new received values are empty.
I think this can be bug in server-side (at text value processing stage).

I don't found any info about this problem and create new thread.

Thanks for attention.

I just setup a trapper with type text using a _fresh_ 1.6.1 and it works.
Can you check your history_text table and see wether it contains the value?

maybe this problem is connected to data displaying only - see https://support.zabbix.com/browse/ZBX-840

[stan.vasiljev]

There was no "..." symbols in frontend - only empty space in item value. So I don't think it's related to https://support.zabbix.com/browse/ZBX-840

note that your report was about 1.6.1, but the bug fas filed around the time when 1.6.4 was released - have you checked with latest version ?

[stan.vasiljev]

I'm using 1.6.2 now - I works fine with Text items - frontend displays their values clearly. Maybe it was problem with 1.6.1 frontend. Sorry, I have failed to
inspect this bug before values were deleted (housekeepered :-).
I'll reconfigure my Str items back to Text type and check results yet another time

I've checked and tested text items today. I haven't found any problems with empty values with hosts which monitored directly by zabbix_server.

BUT problems with empty values present only for hosts and items which monitored through zabbix proxy.

This is test command:
zabbix_sender -z 127.0.0.1 -s"test_host" -k"listTrap" -o"text_test9"

But values in frontend and database are empty:
mysql> select * from history_text where itemid=82836;
+---------+--------+------------+------------+
| id | itemid | clock | value |
+---------+--------+------------+------------+
| 9124267 | 82836 | 1245061318 | |
| 9124564 | 82836 | 1245061749 | |
| 9124605 | 82836 | 1245061810 | |
+---------+--------+------------+------------+

And there is part of zabbix_proxy log about this text item processing:

At insert stage (25706:20090615:063010 Query [insert into proxy_history (itemid,clock,value) values (82836,1245061810,'')]) value is empty. So in frontend we can see actual empty value, but proxy has lost initial value on processing stage. Is it bug of zabbix_proxy ?

Some version info:
zabbix_proxy -V
ZABBIX Proxy (daemon) v1.6.1 (04 November 2008)

zabbix_sender -V
ZABBIX send v1.6.1 (04 November 2008)

i'd suggest testing with the latest version and reporting on the tracker if the problem is still there
