zabbix-mini-IPMI

CPU and disk temperature monitoring scripts for zabbix. Also support voltage and fan speed monitoring on certain configurations. Uses lm-sensors, smartmontools and OpenHardwareMonitorReport. For Linux, BSD and Windows.

Choosing OHMR version

Only custom param-capable versions are supported on Windows 7+:

0.9.6.0

0.9.2.0

0.8.0.5

Version for Windows XP:

0.3.2.0

Installation

As prerequisites you need python3, lm-sensors, smartmontools, sudo and zabbix-sender packages. For testing zabbix-get is also required.
Take a look at scripts first lines and provide paths if needed. If you have custom RAID configuration, also provide that manually. Import Template_mini-IPMI_v2.xml in zabbix web interface.

Debian / Ubuntu

client# apt install python3 sudo zabbix-agent zabbix-sender smartmontools lm-sensors
server# apt install zabbix-get

Centos

client# yum install python3 sudo zabbix-agent zabbix-sender smartmontools lm_sensors
server# yum install zabbix-get

First step

Note: Your include directory may be either zabbix_agentd.d or zabbix_agentd.conf.d dependent on the distribution.

Linux

client# mv mini_ipmi_smartctl.py Linux/mini_ipmi_lmsensors.py sender_wrapper.py /etc/zabbix/scripts/
client# mv Linux/sudoers.d/zabbix /etc/sudoers.d/   # place sudoers include for smartctl sudo access
client# mv Linux/zabbix_agentd.d/userparameter_mini-ipmi2.conf /etc/zabbix/zabbix_agentd.d/

FreeBSD

client# mv mini_ipmi_smartctl.py BSD/mini_ipmi_bsdcpu.py sender_wrapper.py /etc/zabbix/scripts/
client# mv BSD/sudoers.d/zabbix /usr/local/etc/sudoers.d/
client# mv BSD/zabbix_agentd.d/userparameter_mini-ipmi2.conf /usr/local/etc/zabbix/zabbix_agentd.d/

Then, for Intel processor you need to add coretemp_load="YES" to /boot/loader.conf. For AMD it will be amdtemp_load="YES". Reboot or manual kldload is required to take effect.

Windows

client> move mini_ipmi_smartctl.py "C:\Program Files\Zabbix Agent\scripts\"
client> move mini_ipmi_ohmr.py "C:\Program Files\Zabbix Agent\scripts\"
client> move sender_wrapper.py "C:\Program Files\Zabbix Agent\scripts\"
client> move userparameter_mini-ipmi2.conf "C:\Program Files\Zabbix Agent\zabbix_agentd.d\"

Install python3, adding it to PATH during installation for all users. Install smartmontools and add its bin folder to PATH in environment variables. OpenHardwareMonitorReport 0.8.0.5+ requires .NET Framework 4. 0.3.2.0 requires .NET Framework 3.

Second step

Dependent on the distribution, you may need to include your zabbix conf folder in zabbix_agentd.conf, like this:

Include=/usr/local/etc/zabbix/zabbix_agentd.d/

Its recomended to add at least Timeout=10 to server and client config files to allow drives spun up and OHMR execution.

Thats all for Windows. For others run the following to finish configuration:

client# chmod 755 scripts/mini_ipmi*.py scripts/sender_wrapper.py   # apply necessary permissions
client# chown root:zabbix scripts/mini_ipmi*.py scripts/sender_wrapper.py 
client# chmod 644 userparameter_mini-ipmi2.conf
client# chown root:zabbix userparameter_mini-ipmi2.conf
client# chmod 400 sudoers.d/zabbix
client# chown root sudoers.d/zabbix
client# visudo   # test sudoers configuration, type :q! to exit

Testing

server$ zabbix_get -s 192.0.2.1 -k mini.cputemp.discovery[get,"Example host"]
server$ zabbix_get -s 192.0.2.1 -k mini.disktemp.discovery[get,"Example host"]

or locally:

client$ /etc/zabbix/scripts/mini_ipmi_lmsensors.py get "Example host"
client$ /etc/zabbix/scripts/mini_ipmi_smartctl.py  get "Example host"

Default operation mode. Displays json that server should get, detaches, then waits and sends data with zabbix-sender. Example host is your Host name field in zabbix. You might want to use nonexistent name for testing to avoid unnecessary database pollution (client introduces itself with this name and false names will be ignored). 

server$ zabbix_get -s 192.0.2.1 -k mini.cputemp.discovery[getverb,"Example host"]
server$ zabbix_get -s 192.0.2.1 -k mini.disktemp.discovery[getverb,"Example host"]

or locally:

client$ /etc/zabbix/scripts/mini_ipmi_lmsensors.py getverb "Example host"
client_admin!_console> python "C:\Program Files\Zabbix Agent\scripts\mini_ipmi_ohmr.py" getverb "Example host"

Verbose mode. Does not detaches or prints LLD. Lists all items sent to zabbix-sender, also it is possible to see sender output in this mode.

These scripts were tested to work with following configurations:

Updating

Overwrite scripts and UserParameters. If UserParameters were changed - agent restart is required. If template had changed from previous version - update it in zabbix web interface marking all Delete missing checkboxes.

Note: low values in php settings /etc/httpd/conf.d/zabbix.conf may result in request failure. Especially php_value memory_limit.
