Zabbix plugin doesn't appear at "Add data source"

Grafana Installation
1

I just install the Zabbix plugin and it doesn’t appear at “Add data source”. This is a know bug? How to fix it? (Grafana: v7.1.5 and Zabbix v5.0.3.)

I was running into the same issue, Ubuntu 20.04, Zabbix 5.0-1, Grafana 7.1.5, alexanderzobnin-zabbix-app 4.0.1 . I noticed in /var/log/grafana/grafana.log a few things,

"Config loaded from" logger=settings file=/usr/share/grafana/conf/defaults.ini
"Config loaded from" logger=settings file=/etc/grafana/grafana.ini
"Connecting to DB" logger=sqlstore dbtype=sqlite3"
"Failed to load plugin" logger=plugins error="plugin \"alexanderzobnin-zabbix-datasource\" is unsigned" pluginPath=/var/lib/grafana/plugins/alexanderzobnin-zabbix-app/datasource-zabbix"

I had changed my /etc/grafana/grafana.ini to use my MySQL Grafana database yet it was using sqlite3. I also had added “alexanderzobnin-zabbix-datasource” to “allow_loading_unsigned_plugins” in /etc/grafana/grafana.ini . The Zabbix data source was still not loading.

So I added my MySQL database settings and “alexanderzobnin-zabbix-datasource” to “allow_loading_unsigned_plugins” to /usr/share/grafana/conf/defaults.ini . I then reinstalled the plugin using “sudo grafana-cli plugins install alexanderzobnin-zabbix-app” . I checked the log after restarting and now the Grafana log shows,

"Connecting to DB" logger=sqlstore dbtype=mysql"
 "Running an unsigned backend plugin" logger=plugins pluginID=alexanderzobnin-zabbix-datasource pluginDir=/var/lib/grafana/plugins/alexanderzobnin-zabbix-app/datasource-zabbix"

So Grafana looks like it is ignoring the config file “/etc/grafana/grafana.ini” and only using “/usr/share/grafana/conf/defaults.ini” The permissions on “/etc/grafana/grafana.ini” are 640 and 644 on “/usr/share/grafana/conf/defaults.ini” . So maybe that is the issue.

So add any changes you made to “/etc/grafana/grafana.ini” and put them in “/usr/share/grafana/conf/defaults.ini”

------------------------------------------Update----------------------------------------------------------------------

So I compared “/etc/grafana/grafana.ini” and “/usr/share/grafana/conf/defaults.ini” . I’m new to Grafana and did not notice how the config files are commented. I assumed # was the only way to comment yet ; is also used. I also assumed since ; was used on every option in “/etc/grafana/grafana.ini” that it was the way Grafana declared options. So what is happening is that no options are commented out in “/usr/share/grafana/conf/defaults.ini” but all options are commented out in “/etc/grafana/grafana.ini”.

From "`/etc/grafana/grafana.ini`".
##################### Grafana Configuration Example #####################
#
# Everything has defaults so you only need to uncomment things you want to
# change

# possible values : production, development
;app_mode = production

# instance name, defaults to HOSTNAME environment variable value or hostname if HOSTNAME var is empty
;instance_name = ${HOSTNAME}

#################################### Paths ####################################
[paths]
# Path to where grafana can store temp files, sessions, and the sqlite3 db (if that is used)
;data = /var/lib/grafana

From "`/usr/share/grafana/conf/defaults.ini`"
##################### Grafana Configuration Defaults #####################
#
# Do not modify this file in grafana installs
#

# possible values : production, development
app_mode = production

# instance name, defaults to HOSTNAME environment variable value or hostname if HOSTNAME var is empty
instance_name = ${HOSTNAME}

#################################### Paths ###############################
[paths]
# Path to where grafana can store temp files, sessions, and the sqlite3 db (if that is used)
data = data

So make sure you remove the ; before each option in “/etc/grafana/grafana.ini” that you want to enable.

@jwuorenmaa, thank you so much!!!

I was getting crazy because all I have done (even including the plugin in unsigned option) haven’t worked …

this tip saved me a ton of hours…

Hey! But what option did you have to enable to make it work? :slight_smile:

In /etc/grafana/grafana.ini (around line 696) add the plugin name “alexanderzobnin-zabbix-datasource” to the allow_loading_unsigned_plugins variable and restart Grafana:

# Enter a comma-separated list of plugin identifiers to identify plugins that are allowed to be loaded even if they lack a valid signature.
allow_loading_unsigned_plugins = alexanderzobnin-zabbix-datasource
