Somebody help me !! URGENT!!

[Bharathu]

Hi!!

I'm using Zabbix 1.1 beta 4. The zabbix server was installed in Linux. I was not able to get my Windows agent communicate with my zabbix server. i always get this message in my zabbix_agentd.log.

[09-Jan-2006 14:42:32] *************** Log file opened ****************

I'll get the ball rolling. I haven't ever tried running a Zabbix Agent on a Win32 box. That said, I have used Windows extensively otherwise, and my first guess would be that your agent can't connect because a firewall running on Windows is blocking the port Zabbix uses.

[cameronsto]

Is there a firewall between the agent and server blocking requests to port 10051?

[elkor]

Are you only using active checks for the windows box? regardless of a firewall blocking inboud 10051 traffic, if outbound (server -> agent) 10050 traffic is allowed "zabbix agent" type items should function regardless of this message being present in the agent's log file

[Bharathu]

No firewall on my PC

Firstly thanks for ur replies....but i dont have any firewalls installed on my PC. Also i ran the agent in 2 modes i.e. "c:\zabbixw32 start" and also in "c:\zabbixw32 standalone". In both ways i get the same error in my log file. In my web interface i see 0 in the field of "number of values stored".

When i ran my server on the linux box, it was creating 11 threads in total. But when i run the command "strace zabbix_server" i get this message....as follows.

Ok,

one thing at a time. firstly you have your zabbix server

next you have the box you're monitoring (your pc?) regardless of operating system.

on the server, through the web interface you must first add the host to be monitored in the configuration/hosts section. When that is done you must add items that you want to monitor for that host in the configuration/items section. To be useful for alerts you should add triggers for the items as well in configuration/triggers but that can be done at a later date.. let's just verify you can collect data.

Add an item that is checked somewhat frequently and will show activity.. such as cpu load or something. For simplicity sake, have it be of a "zabbix agent" type.

then fire up the agent on the machine to be monitored, don't worry about the could not communicate with server messages for now. That message just means that the agent can't "call home" to the server to see if it has any active checks to make; it is 100% possible that the system could be working just fine and you still get that message in the agent's log.

post back here and let us know what you've got.

Still in problem

Hi

I tried as you said. I added a host with "host name = 10.239.19.120" this machine has the agent installed and is working on win XP. I also selected "use IP" and entered the same IP of my host. I selected the port to 10051. I did not add anything from the templates. I clearly dont know wat to do with them...so didnt touch it.

Next i added an ITEM with "description = cpu load", host = 10.239.19.120, type = zabbix agent, and left key and units fiels NULL. This is still not working....when i went to "Monitoring/Latest data"...... it is just showing a "-" for "cpu load" in the last check, last value & change fields.

I found that it was showing "Cannot connect to [10.239.19.120] [Connection refused] " in Configuration/Host ( for my host --> 10.239.19.120)

[Alexei]

Next i added an ITEM with "description = cpu load", host = 10.239.19.120, type = zabbix agent, and left key and units fiels NULL.

1. Item's key must not be empty!
2. Check if ZABBIX server is listening port 10051 (netstat -an|grep 10051)
3. Try to connect to ZABBIX server from the monitored host (telnet <server> 10051)

[Bharathu]

item key

hi...
wat should i type in item key? for example for cpu load...wat should i take as the key?? And i cannot use telnet..... it does not work....
And i get this message when i use netstat command

[zabbix@localhost bin]$ netstat -an|grep 10051
tcp 0 0 0.0.0.0:10051 0.0.0.0:* LISTEN

Please Help

one more thing ....i could not configure the zabbix server with "net-snmp"support as it gave me errors. So i did not use the option "--with-net-snmp" while configuring the server.
Please send me some valuable tips.... thanking u all in anticipation
Bharathu

[elkor]

documentation is here for item key syntax. The name is simply a label, it is the key that tells the server what to actually monitor.

for cpu load the key is system.cpu.load.

I know the documentation is sparse, but as soon as you get connectivity I HIGHLY suggest you spend some time going through it and working with the program in detail or it will be a very rocky road

[Bharathu]

thanks

hi
Thanks for the info. I will surely go through the documentation once again as u said. But can u please help me in checking whether my configuration files (server & agent) are correct?? I have attached them in my first post. Also i really dont understand how to make the s/w run in polling mode or active check mode. I heard that active check is the best...please can u help me by just giving an example on how to configure the active check mode and the polling mode. I'm getting confused with terms "server port", "listen port", "listen ip" etc... i feel i am going wrong somewhere here ....which is leading to my problems...
thanking u all in anticipation

Bharathu

[Bharathu]

can anyone check my config file?

please... can u check the config file i attached and tell me if i have them right!!! Please guys anyone with any ideas? I am still not able to record any values!!!

telnet problem

hi i did telnet to my linux server from the windows host(telnet 10.239.18.13 10051)... and then immediately i used the netstat command on my linux box to see (netstat -an |grep 10.239.19.120 )
Then i got this message....
tcp 0 0 10.239.18.13:10051 10.239.19.120:4962 ESTABLISHED

later after some time it goes into this state as below

tcp 0 0 10.239.18.13:10051 10.239.19.120:4962 TIME_WAIT

Dont know why this is happening? How and why it is going to TIME_WAIT state ?? need urgent help..please !!!!!
