Can you telnet from agent to server on port 10051?

Did you install an agent on the server as well? What happens with that agent when you monitor it?

**marc1911** · 23-10-2007, 14:55

Yes I'm able to telnet from the agent to the server:

1) I did this:
# telnet zabbix 10051
Trying 192.168.2.208...
Connected to zabbix.
Escape character is '^]'.
quit
Connection closed by foreign host.

2) When I've the Agentd active on the server the log file shows up like this:

12158:20071023:084751 zabbix_agentd started. ZABBIX 1.4.2.
12159:20071023:084751 zabbix_agentd collector started

12164:20071023:084751 In get_min_nextcheck()
12164:20071023:084751 Sleeping for 60 seconds

I've executed the same tests as with the seperate agent (php4.cellar.home) and I see no differences.

Could there be an incompatibility between OpenVZ and Zabbix?
Can't seem to get zabbix_sender to work either?

any idea's left?

**swaterhouse** · 24-10-2007, 14:31

Can you install, start and add an agent on the same host as the zabbix_server host? If so are you getting anything from that agent?

Edit:

I doubt OpenVZ has anything to do with it, you are running CentOS as the guest operating systems and they work fine with ZABBIX, there has to be something else going on.

I run ZABBIX within CentOS on both VMware Server (free version) and VMware ESX server and I know there are others using some of other virtualization tools.

**marc1911** · 24-10-2007, 14:41

I've done that already see post of Yesterday 14:55 point 2).

Enabling the agent on the server doesn't make any difference. No data comming in either. I've already compiled, installed and configured Zabbix 1.4.1. But I've the same problem here.

Could it have something to do with this 1970 date issue in the queue?
I'm very much out of idea's right now. Hope you have some suggestions left?

Marc

Hi there,

Is there anyone how can help me getting Zabbix up and running?
In the meanwhile I've completly re-installed Zabbix from scratch!
Instead off having CentOS v5 as host for Zabbix I've used CentOS v4.4 as the host platform but still running as a VPS on OpenVZ. And what do you know??
It still isn't working!! I've followed the instructions on http://www.zabbix.com/wiki/doku.php?...:centosinstall. Even if this wiki is missing some important instructions like:
1) adding the ports in /etc/services;
2) changing the /var/lock/subsys in the daemon startup file for the agent and server to a directory that's is writable to the Zabbix user
3) installing Fping because it fails by default on Centos v4

Furthermore I've tested communications between agent and server like described earlier in this thread and no problems here. So why isn't the frontend getting any data in the database???????? HELP HELP HELP

Regards,

Marc

Your screen shot of the host setup shows that you haven't selected a template for that host. You need to select a template, in your case Template_Linux template, otherwise you wont get any data as the agent doesn't know what metrics it should be monitoring.

The problem is solved!
If you read my zabbix_server.conf file at point 4.5 in thread post "23-10-2007 12:29" it says "NodeID=1".
I need to make it "NodeID=0" to be able to retreive data.

Yipeeeee!!!!!
Solved it myself.

**Calimero** · 25-10-2007, 13:42

I see that your zabbix_server has NodeID=1.
Did you upgrade your database to "distributed monitoring mode" (zabbix_server --new-nodeid 1) ?

What if you create simplechecks (ping) instead of zabbix_agent items ?

Edit: you made the same mistake as I did ("Yeah let's define a NodeId despite this is a standalone server"

)

**marc1911** · 25-10-2007, 13:49

Can't see any data comming up in frontend ** solved **

No I did't upgrade the database to "distributed monitoring mode". I just started with the so simple installation instructions and overlooked the fact that the NodeID needed to be set to 0 for a standalone server. But than again, this is easy overlooked because the remarks in the server configuration file says:

# This defines unique NodeID in distributed setup,
# Default value 0 (standalone server)
# This parameter must be between 0 and 999

And furthermore the standalone option isn't explained in the manual, so it was searching for a needle in a haystack if you ask me.

**Calimero** · 25-10-2007, 13:52

I've wasted 2 days on this too.

Running zabbix_server in debug mode and then finding out in the code where that "host_id" condition came from, in the sql queries.

I am glad you got it working, I havent done anything with DM and never would have caught that one.

As far as the wiki instructions go feel free to edit them, below are some remarks on your comments.

1) this is not a critical step nor is it required - I tried to make the instructions as easy as possible

2) I never had to do this on any of my systems setup ith the instructions provided.

3) again not required for all installations and I was trying to make the instructions as easy as possible - maybe this can be added as an optional step.

The Hostname must be set to 'test' in zabbix_agentd.conf to make active checks work.
