Hi
I have the same problem too.Unfortunately with changing "Timeout" option to 30 the problem was not solved!!
I think this problem is related to bug on agentd in 1.8.2!

Thanks for any help or guidance

Hello together,
would be great to get an explanation of the logged errors.
I asume the errors will not be logged just for fun.
So the main questions are:

• What are the possible causes of the problem?
• What are the consequences of this type of error messages?
• What are possible solutions?

Thanks
Frank

Hi
1. Check firewall ports 10050 on Server and agents
2. Check zabbix_agent.conf ServerPort (default 10051) and ListenPort (default 10050), hostname (must be the same on zabbix_server and agent, important register!)
3. Try get result from zabbix manually:
zabbix_get -sHOST -kITEM_DESCRIPTION
4. If yours host and server don't use IPv6, don't compile zabbix with support IPv6

Yours item is ok. I also used this item:

perf_counter[\PhysicalDisk(0 C:)\Avg. Disk Queue Length]

[frankp]

Morning ruswold,
thanks for your comment.
Since I've already checked your suggestion 1, 2, and 3, number 4 could be the cause.
I'll look into this next week.

Have a nice weekend

Hi everybody!

I have meet the same trouble.

My configuration:
Zabbix Server

- CentOS release 5.5 (Final)
- Linux lin1.mydomain.ru 2.6.18-194.11.1.el5 #1 SMP Tue Aug 10 19:05:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
- Zabbix Server v1.8.2 (revision 11211) (29 March 2010)

Zabbix Client:

- Windows 7 Ultimate 64-bit
- system.uname: Windows WIN7 6.1.7600 Windows Server 2008 AMD-64
- agent.version: 1.8.2

Zabbix Server running in vmware on the Zabbix Client

Zabbix Agent normally working and collecting items except "perf_counter".
Error message:

4599:20100817:105631.979 Item [WIN7: perf_counter[\\System\\File Read Bytes/sec,1]] error: Get value from agent failed: ZBX_TCP_READ() failed [Interrupted system call]

But!!! zabbix_get is working !!!

lin1# ./zabbix_get -sWIN7 -k"perf_counter[\\System\\File Read Bytes/sec,1]"
1805.569236
lin1#

Do you have any idea?

[ruswold]

./zabbix_get -sWIN7 -k"perf_counter[\\System\\File Read Bytes/sec,1]
Do you have any idea?

I think you use wrong key. It should be like:
perf_counter[\System\File Read Bytes/sec]

[Utyf]

I think you use wrong key. It should be like:
perf_counter[\System\File Read Bytes/sec]

Yes. You right!
I used "Template Windows", that used "\\System..".
Now I created Item manually with "perf_counter[\System\File Read Bytes/sec]", it working !

Why "Template Windows" used wrong syntacsis?
And why zabbix_get working with wrong sintacsis?
