Note: master is WiP. Use the latest release for now.
Cross-platform SMART monitoring scripts with two display modes: device and serial. LLD discovers and sends data in one pass, using minimal number of utilities. Supports any SMART name and displays it as is.
- Utilises smartctl error return codes
- Low-Level Discovery
- SAS support
- SSD wear monitoring (SAS only)
- csmi support
- Efficient: no unnecessary processes are spawned
- Bulk items upload with zabbix-sender
- Error-proof configuration: various safeguard triggers
- Automatic RAID passthrough (when smartctl detects the drives)
Note: disk temperature is monitored using different approach.
Triggers that contain delta(5d)>0 and last()>0 will fire on any change unless last value is zero. E.g. when disk is replaced with zero values the trigger will not fire, but if value is less or more - it will. Therefore, replacing a faulty drive with faulty one will still trigger a problem that stays for 5 days (default).
As prerequisites you need python3, 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 a RAID configuration, also provide that by hand. Choose device or serial mode. Import Template_App_smartmontools.xml in zabbix web interface.
apt-get install zabbix-agent zabbix-sender smartmontools sudo python3-setuptools

sudo cp /usr/share/doc/examples/zabbix-smartmontools/sudoers.d/zabbix /etc/sudoers.d/zabbix
sudo cp /usr/share/doc/examples/zabbix-smartmontools/zabbix-smartmontools.conf /etc
sudo install -m 644 Linux/zabbix_agentd.d/userparameter_smartctl.conf /etc/zabbix/zabbix_agentd.conf.d/sudo python3 setup.py install

sudo install -m 644 BSD/zabbix_agentd.conf.d/userparameter_smartctl.conf /usr/local/etc/zabbix42/zabbix_agentd.conf.d/python setup.py install
move zabbix-smartmontools.conf C:\zabbix-agent\
move Win\zabbix_agentd.conf.d\userparameter_smartctl.conf C:\zabbix-agent\zabbix_agentd.conf.d\Install python3 for all users, adding it to PATH during installation. Install smartmontools and add its bin folder to PATH in environment variables (or specify absolute path to smartctl binary in zabbix-smartctl.exe).
Note: currently windows version does not detaches and data can only be gathered on second run.
Then you need to include your zabbix conf folder in zabbix_agentd.conf, like this:
Include=/usr/local/etc/zabbix/zabbix_agentd.conf.d/
That's all for Windows. For others run the following to finish configuration:
sudo vim /etc/zabbix/zabbix-smartmontools.conf # Review settings
sudo visudo # test sudoers configuration, type :q! to exitzabbix_get -s 192.0.2.1 -k smartctl.discovery[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.
zabbix_get -s 192.0.2.1 -k smartctl.discovery[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.
Note: before scripts would work, zabbix server must first discover available items. It is done in 12 hour cycles by default. You can temporary decrease this parameter for testing in template -> Discovery -> SMART disk discovery -> Update interval. In this monitoring solution update interval must not be less than 80 seconds.
These scripts were tested to work with following configurations:
- Centos 7 / Zabbix 3.0 / Python 3.6
- Debian 9 / Zabbix 3.0 / Python 3.5
- Ubuntu 17.10 / Zabbix 3.0 / Python 3.6
- FreeBSD 12.1 / Zabbix 4.2 / Python 3.7
- Windows XP / Zabbix 3.0 / Python 3.4
- Windows 7 / Zabbix 3.0 / Python (3.4, 3.7, 3.8)
- Windows Server 2012 / Zabbix 3.0 / Python 3.7
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.
Q: Trigger fires when it clearly shouldn't.
Q: Trigger's macro does not expand.
Q: Triggers from older version does not expire after update.
A: Reassign the template with Unlink and clear on the host for individual resolution. Or reupload the tempate marking all Delete missing checkboxes.
Q: Is it possible to monitor specific drives or exclude some of them?
Q: SCSI drive returns empty results while -A option working correctly.
A: Specify [Disks] in zabbix-smartmontools.conf:
[Disks]
/dev/sda: -d sat+megaraid,4
/dev/sda: -d sat+megaraid,5
/dev/csmi0,0: -d scsi
/dev/csmi0,1: -d scsiQ: Old triggers are misleading after disk replacement.
A: Wait for 24 hours (default) or perform Unlink and clear on the host. You can also adjust the interval at template -> Discovery -> SMART disk discovery -> Keep lost resources period.
Q: Triggers Command line did not parse and Device open failed serves identical purpose in zabbix-smartmontools and zabbix-mini-IPMI.
A: Disable unneeded pair in either template.
Q: Script exits with exception/error.
A: Report it.
- Zabbix web panel displays an error on json discovery, but everything works fine (#7)
- Data on some systems may be absent right after boot due to AHCI warmup (#14)
- Windows version does not detaches, and data will only be gathered on second pass (probably permanent workaround)
