1.4.1 agent problems?

[workinonit]

I am new to zabbix and today installed 1.4.1 however I am having a few problems getting monitoring working. The first problem is adding a host. I get the following error on the "Configuration" > "Hosts" screen:
maxpower maxpower 192.168.1.90 10050 Template_Linux Monitored Not available ZBX_TCP_READ() failed [Interrupted system call]

So it would seem that the agent cannot connect to the server. The agent and server are the same computer. Here is my zabbix_agentd.conf

# This is config file for zabbix_agentd

As you can see I have tried playing around with "localhost" or "hostname". My second problem is no output is getting written to the log file so I am having a hard time debugging things. I am using Ubunutu 7, MySQL, Apache, PHP5.

In short:
Agent not working?
ZBX_TCP_READ() failed [Interrupted system call] when trying to add host
No output to zabbix_agentd.log

Please help

Because the agent is running on the same machine as the server then everything needs to point to localhost

Configuration" > "Hosts" screen:
maxpower maxpower 127.0.0.1 10050 Template_Linux

and use IP not DNS

Set up config as below

# This is config file for zabbix_agentd
# To get more information about ZABBIX, go http://www.zabbix.com

############ GENERAL PARAMETERS #################

# List of comma delimited IP addresses (or hostnames) of ZABBIX servers.

# IP address to bind agent

#ListenIP=127.0.0.1

For your logging problem, make sure that

/var/log/zabbix-agent/

directory exists and that the user zabbix has permission to write to it.

Changed the config file, the error is gone but now this shows up in the agent logs:

I killed all zabbix_agentd processes and started it again each time I get this. I will double check my server and agent configs to make sure they are listening and responding on ports 10050 and 10051. What could be going on?

Triple check this!

Hello,

Zabbix server: 1.4.1 on Linux RHEL 4.4
Zabbix agent: 1.4.1 on HP-UX 11.00

It seems I have a very similar problem...

Indeed, I have the following error under zabbix GUI:
140.94.2.54 10050 Template_HPUX Monitored Not available ZBX_TCP_READ() failed [Interrupted system call]

And in zabbix_agentd logfile:

 13429:20070723:114233 Got SIGPIPE. Where it came from???

I have already installed many zabbix agents on several plaforms (Solaris, HP-UX, Linux) but this problem only appears with HP-UX 11.00, and a few hours after running zabbix agentd.

I tried several solutions mentioned on this page, but the problem is still here...
Any ideas?


Thank you very much for your help.

Hello again,

I am still investigating this error:
ZBX_TCP_READ() failed [Interrupted system call]

The bad news is that I get it randomly on a HP-UX 11.11 platform too!

Please, is there a way to track efficiently this pb in order to solve it?
Can someone send me a precompiled agent for HP-UX 11.00 or 11.11?


Thank you for your help.

I am still investigating this error:
ZBX_TCP_READ() failed [Interrupted system call]

This is just an informative message that can be ignored in most cases.

[steria]

Thanks for your reply.

The thing is that data are not collected anymore when the problem occurs...the only solution is to restart agent but the pb comes back very fast.

It is really penalizing since I have several HP-UX server to supervise.

Some people seem to have solved the pb by changing the agent configuration but wathever I try does not work.

Please, let me know if you have any ideas or a if a precompiled agent is available. Could this pb come from compilation phase?

Thank you.

[steria]

Hello again,

I forgot to mention that in order to compile for HP-UX 11.00, I replaced every reference to sysinfo.h by unistd.h in the configure script. I found this solution on the forum.

Could the error "ZBX_TCP_READ() failed [Interrupted system call]" come from this modification?

Thank you

[bashman]

May be this can help:
