UserParameter execution environment

[MurgaNikolay]

Hi all.

I have ruby script and ruby installed via rvm.

In my user agent I have something like this:

UserParameter=test.parameter,cd /home/zabbix/scripts && ./statistic.rb

In statistic.rb:

#!/usr/bin/env ruby
puts '1'

It's simplified example. Real script is biggest.

If I run using ssh console - all is ok, I have '1'
But in UserParameter is not worked. Problem in the environment.

I've try get environment variables:

UserParameter=test.env,export

~$ zabbix_get -s localhost -k "test.env"
export LANG='en_GB.UTF-8'
export PATH='/home/ubuntu/.rvm/gems/ruby-2.0.0-p0/bin:/home/ubuntu/.rvm/gems/ruby-2.0.0-p0@global/bin:/home/ubuntu/.rvm/rubies/ruby-2.0.0-p0/bin:/home/ubuntu/.rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/sbin:/sbin:/usr/sbin:/sbin'
export PWD='/'
export TERM='xterm-256color'

I don't have right HOME variable for zabbix user and I have a rubbish a '/home/ubuntu/.rvm/gems/ruby-2.0.0-p0/bin'. It's PATH from ubuntu user!!!
For load RVM I need zabbix user environment variables and logged shell.
I try run a command using `bash -l -c`, but result is not better.

UserParameter=test.env,bash -l -c 'export'

~$ zabbix_get -s localhost -k "test.env"
declare -x LANG="en_GB.UTF-8"
declare -x OLDPWD
declare -x PATH="/home/ubuntu/.rvm/gems/ruby-2.0.0-p0/bin:/home/ubuntu/.rvm/gems/ruby-2.0.0-p0@global/bin:/home/ubuntu/.rvm/rubies/ruby-2.0.0-p0/bin:/home/ubuntu/.rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/sbin:/sbin:/usr/sbin:/sbin"
declare -x PWD="/"
declare -x SHLVL="1"
declare -x TERM="xterm-256color"

And only if change commad to:

UserParameter=test.env,HOME=~zabbix bash -l -c 'export'

I got less work result:

declare -x HOME="/home/zabbix"
declare -x LANG="en_GB.UTF-8"
declare -x OLDPWD
declare -x PATH="/home/ubuntu/.rvm/gems/ruby-2.0.0-p0/bin:/home/ubuntu/.rvm/gems/ruby-2.0.0-p0@global/bin:/home/ubuntu/.rvm/rubies/ruby-2.0.0-p0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/sbin:/sbin:/usr/sbin:/sbin:/home/zabbix/.rvm/bin"
declare -x PWD="/"
declare -x SHLVL="1"
declare -x TERM="xterm-256color"
declare -x _system_arch="x86_64"
declare -x _system_name="Ubuntu"
declare -x _system_type="Linux"
declare -x _system_version="12.04"
declare -x rvm_alias_expanded
declare -x rvm_bin_flag
declare -x rvm_bin_path="/home/zabbix/.rvm/bin"
declare -x rvm_configure_env
declare -x rvm_configure_flags
declare -x rvm_delete_flag="0"
declare -x rvm_docs_type
declare -x rvm_file_name
declare -x rvm_gemstone_package_file
declare -x rvm_gemstone_url
declare -x rvm_make_flags
declare -x rvm_niceness
declare -x rvm_nightly_flag
declare -x rvm_only_path_flag
declare -x rvm_path="/home/zabbix/.rvm"
declare -x rvm_prefix="/home/zabbix"
declare -x rvm_proxy
declare -x rvm_quiet_flag
declare -x rvm_ruby_alias
declare -x rvm_ruby_bits
declare -x rvm_ruby_file
declare -x rvm_ruby_make
declare -x rvm_ruby_make_install
declare -x rvm_ruby_mode
declare -x rvm_ruby_string="system"
declare -x rvm_script_name
declare -x rvm_sdk
declare -x rvm_silent_flag
declare -x rvm_sticky_flag
declare -x rvm_system_flag
declare -x rvm_use_flag
declare -x rvm_user_flag
declare -x rvm_version="1.25.25 (master)"
declare -x rvm_wrapper_name

But I think it's bad temporal solution.
Same results if I use system.run[].

I have many scripts that should run in the user's environment zabbix.
Perhaps there is a more elegant solution for load user environment?
Thanks.

PS: Zabbix env from console.

~$ export
declare -x HISTCONTROL="ignorespace"
declare -x HOME="/home/zabbix"
declare -x LANG="en_GB.UTF-8"
declare -x LANGUAGE="en_GB:en"
declare -x LC_ALL="en_GB.UTF-8"
declare -x LC_CTYPE="en_US.UTF-8"
declare -x LOGNAME="zabbix"
declare -x MAIL="/var/mail/zabbix"
declare -x MC_SID="9922"
declare -x MC_TMPDIR="/tmp/mc-zabbix"
declare -x OLDPWD="/home/zabbix/scripts"
declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/zabbix/.rvm/bin:/home/zabbix/.rvm/bin"
declare -x PWD="/home/zabbix/scripts"
declare -x SHELL="/bin/bash"
declare -x SHLVL="2"
declare -x TERM="xterm-256color"
declare -x USER="zabbix"

which bash has zabbix?

can you run this script as zabbix-user?

[MurgaNikolay]

Yes, I can run this script as zabbix and all is ok.
This script wrote on ruby, and I want run it on rvm.

Now I have something like this and this worked:

UserParameter=test.env,HOME=~zabbix bash -l -c 'my command'

So I think this question can be closed.

/etc/default/zabbix-agent

DISCLAIMER: I'm posting this to a few old threads because google got me there and it might help other people.

If you wanna set environment variables for your UserParameters or any other things that is run by the zabbix-agent, place them in /etc/default/zabbix-agent. The default systemd's zabbix-agent service unit has an parameter for sourcing it (EnvironmentFile=-/etc/default/zabbix-agent). The file doesn't exist by default, hence the minus (-) before the path (in systemd, an minus in front of the file avoid error if the files doesn't exist).

If you're still using SysVinit (/etc/init.d scripts), then take a look at zabbix-agent's script (/etc/init.d/zabbix-agent) search for the following lines:

[ -r /etc/default/zabbix-agent ]

if it's not there, add it.

After that, restart the service. Profit.

PS: You can try your zabbix-agent environment this way:
add this to your agent's config:

UserParameter=test.env,export

Restart your zabbix-agent and run

zabbix_get -s localhost -k test.env
