No information back

[malik]

Hello,

I have two problems :

1) I have Red Hat server in ZABBIX, zabbix icon is not green (and not red, it's gray).
I use a zabbix proxy, commands TELNET are OK, zabbix agent file is configured and logs are not critical, but I can not find the solution.

2) Too, I have a other linux wich has the zabbix logo green but, nothing information back to zabbix server. Yet, commands TELNET is OK too and nothing in logs, why ?

Thank for your help.

Malik.

can be agent`s config file issue

[frankymryao]

while a host is no data trans to server(or proxy), try:

1.agent down?
2./usr/local/zabbix/bin/zabbix_get -s IP -k KEY(usually system.hostname or some key else you want to check)
3.review agent log

[malik]

For the agent, I think it is ok

The problems of icons ZABBIX gray was the routing, now they are ok, servers totality are green, but I have nothing in "Latest Data" always.

1. Agent is up, I have restart.
2. I don't understand this, can you explain ?
3. In agent log, I have nothing, but proxy log, I have this :

Item [my-host:rg.log.error] error: Get value from agent failed:ZBX_TCP_READ() failed [Connection reset by peer]

[Z3005] Query failed: [2006] MySQL server has gone away [begin;]
  
Zabbix Host [my-host]: another network error, wait for 15 seconds
  
Zabbix Host [my-host]: first network error, wait for 15 seconds

1. agent restart successfully? check agent log?
2. '/usr/local/zabbix/bin/zabbix_get' allows you to get value in command line. For example, I want to get the hostname from 127.0.0.1, I can use '/usr/local/zabbix/bin/zabbix_get -s 127.0.0.1 -k system.hostname' to get. You can use it to check your item is working well. Details for it you can find in zabbix manual.
3. ZBX_TCP_READ() failed perhaps occurred because there are wrong ip(or hostname) in your zabbix_proxy.conf. I've encounted this issue long ago. Sorry I cannot remember it. You can google for it.
4. From log, something is wrong with MySQL of your proxy

2. Zabbix is not exist in "/usr/local/", it's normal ?

3. I verified in zabbix_proxy.conf, all is OK.

4. I restart mysqld, I waiting and I look logs after.

Thank for your help.

Don't mention it

My zabbix is installed in /usr/local. The exact place depends on your prefix while you install. A simple method to found it is to check your /etc/init.d/zabbix_proxy (vi/vim).

In my opinion, it is nessessary to check item with zabbix_get first

[malik]

Yes, my file "zabbix_get" is in "/usr/local/bin/"

'/usr/local/zabbix/bin/zabbix_get -s 127.0.0.1 -k system.hostname'

But, the command return nothing.

[frankymryao]

Yes, my file "zabbix_get" is in "/usr/local/bin/"

'/usr/local/zabbix/bin/zabbix_get -s 127.0.0.1 -k system.hostname'

But, the command return nothing.

Have you replace "127.0.0.1" to the IP you installed zabbix_agent in? 'system.hostname' is the basic key in zabbix. If you cannot get the value of any agent, there must be wrong

[malik]

On zabbix proxy :
- The file zabbix_agentd : hostname = qwerty
- The file zabbix_proxy : hostname = qwerty

I use this command :

 /usr/local/bin/zabbix_get -s qwerty -k system.hostname

Command return this error :

zabbix_get [7323]: Get value error: gethost() failded for address 'qwerty' [success]

Why this error ?

Thank you,

Malik.

you should use IP to replace to qwerty

[malik]

I tried replace "qwerty" by IP of server zabbix, but nothing in command return.

NOTHING？“ZBX_NOT_SUPPORTED” showed ？

if not, the link between your agent and server DID NOT work any more

[malik]

Sorry, I think I did a error.

I executed this command on zabbix proxy

/usr/local/bin/zabbix_get -s IP-server-zabbix -k system.hostname

Response :

zabbix_get [9388] : Timout while executing operation

telnet 10050(zabbix default port)?
