Graphs - Not being Displayed

[brianstivala]

Hi,

Thanks for your reply but however I've decided to remove everything, Zabbix is really hard to install and configure for newbies. I've also followed a document (attached) which is very explained and I had problems too. I had a problem with server_agentd.conf, (server is unreachable in zabbix). If you have a document which is very explained kindly share with me.

Regards,

Unfortunately I don't have a document and I struggled myself during first Zabbix setup, I can give you some notes for Fedora which I composed:

Zabbix server:

1. Unpack sources

2. Install database, example is as follows (for mysql):

shell> mysql -u<username> -p<password>
mysql> create database zabbix character set utf8;
mysql> quit;
shell> cd create/schema
shell> cat mysql.sql | mysql -u<username> -p<password> zabbix
shell> cd ../data
shell> cat data.sql | mysql -u<username> -p<password> zabbix
shell> cat images_mysql.sql | mysql -u<username> -p<password> zabbix

3. Configure and compile zabbix server, for example:

shell> ./configure --enable-server --with-mysql --with-net-snmp

4. Install:

shell> make install

5. Create a folder /etc/zabbix and copy there zabbix conf file for server. Configure it to match your server data.

6. Copy start app scripts for your system, for example:

cp misc/init.d/redhat/zabbix_server_ctl /etc/init.d/zabbix_server_ctl

and make it executable.

After each component is installed I make some clean up:

make clean

Zabbix Agent:

1. Add zabbix user and group

2. Configure and compile agent:

./configure --enable-agent

3. Install agent

make install

4. Modify /etc/services to include these lines

zabbix_agent 10050/tcp 
zabbix_trap 10051/tcp

5. Copy start app scripts for your system, for example:

cp misc/init.d/redhat/zabbix_agentd_ctl /etc/init.d/zabbix_agentd_ctl

and make it executable.

6. Copy zabbix_agentd.conf to /etc/zabbix. Make sure that Server and Hostname are correctly configured, safe assumption is to make names consistent across all three zabbix components (server, agent, GUI)

Troubleshooting:

I have had lots of issues during my first setup, but the logic is follows if something does not work:

1. Check zabbix logs, look for clues
2. Make sure that SELinux is disabled
3. Make sure that firewall rules allow server-agent communication (in fedora its

system-config-firewall

executed directly from the console)
4. Double check conf files

Lots of interesting information is located here: http://www.zabbix.com/wiki/howto/install/start

Just choose relevant operation system, lots of clues are there. Best apporach for me is to install dependencies from package repositories and install zabbix from source.

P.S. as far as your server unreachable problem (in case server is up) is concerned most likely you should check that hostname parameters are consistent in zabbix_agentd.conf and in GUI, second thing to check is firewall rules - make sure that ports 10050-10051 are not blocked on the either side.

the reason your graph wasn't showing up is the time is WRONG.. your graph is showing 19:17 but your clock shows 20:17

I have seen this issue in the past...

[brianstivala]

Thanks for the reply,

I will try to install zabbix for the fourth time and I will let you know if problems should arise, which they will.

@Axilla

The time was not an issue because I've installed Zabbix 3 times more from the first time and I did manage to fix the Time.

The only problem I am facing is server_agentd.conf. when I try to stop the server it fails and in Webgui it shows (Server is unreachable) Both ports are opened on my firewall as well. SELinux is disabled and IPTables are off.

I will install zabbix again later on and I will keep you updated with screenshots. Do you have live account such skype or msn messenger to share with me, it's much easier to communicate.

Hi,

So I've installed zabbix again following the attached previous document and the same problem occurs to me.

I'm attaching screenshots regarding problem I'm facing with zabbix with zabbix, if I cant get zabbix_agentd to work is not going to work at all for me.

The zabbix_Server starts
The Zabbix_Agentd starts but when I type stop it fails.

Advise if you need more information.

Regards,
Brian

1. Check your start up script (most likely in /etc/init.d/ folder)
2. Check zabbix logs

Most likely your problem relates to inconsistent specification of the pid file in zabbix agentd conf file and your start up scripts.

However it looks like a minor problem, you can just kill it

Hi,

Apologies for the late reply, I'm not into scripts and I'm a newbie on linux.
However I've pasted as per below the zabbix_agent.conf maybe you can find something wrong and I can change it.

Zabbix_agentd in init.d folder
