You need a Linux VM to collect json files from ESXi hosts. This can be a separate VM or Zabbix server itself but separate one is recommended. Assume VM name is raidmon. Create a user to let ESXi hosts send json files to raidmon VM by SCP. Let's name this user esxi-raidmon for example.
You need to generate SSH key pair for this user by using ssh-keygen -t ecdsa or by your preffered method. Place public key into /home/esxi-raidmon/.ssh/authorized_keys. Dont't forget to limit access to this file:
chown esxi-raidmon:esxi-raidmon /home/esxi-raidmon/.ssh/authorized_keys
chmod 600 /home/esxi-raidmon/.ssh/authorized_keys
Rename private key file to $VMName_$UserName_id. This will be raidmon_esxi-raidmon_id in our example case.
Connect by SSH to your ESXi host and install StorCLI. You can use package found in this repository or download it from Broadcom web site.
esxcli software vib install -v /tmp/VMWare-ESXi7.0-StorCLI.zip --no-sig-check
Change dir to /vmfs/volumes. Move to one of the host's VMFS volumes and create directory to store scripts and id files. Copy all .sh files from repository scripts folder and raidmon_esxi-raidmon_id file to this directory. Make install script executable by chmod 755 install.sh
You need to edit install.sh and send-raid-stats.sh scripts and provide at least correct address of raidmon VM. Don't forget to change TARGETNAME and USER variables if you are using your own values.
Now you can run install.sh script. This will enable outbound SSH firewall rule, connect by SSH to raidmon VM to generate and save known_hosts file and add init-raid-stats.sh to /etc/rc.local.d/local.sh of ESXi host to make monitoring persistant across reboots. When SSH session started you need just accept fingerprint and press ENTER three times to skip connection. You don't need to provide password to connect to raidmon VM.
You can check /etc/rc.local.d/local.sh to be shure init-raid-stats.sh is added before "exit 0" line.
Now you can manually run init-raid-stats.sh script to add main send-raid-stats.sh to CRON and start sending StorCLI json files to raidmon VM without ESXi host reboot. Check that raidstatus_* files are present in /tmp dir of your raidmon VM.
Install "Zabbix Agent 2" on raidmon VM, add this VM to your Zabbix server and attach "Template LSI RaidMon ESXi hosts discovery" to it. Make shure Zabbix Agent have access to /tmp/raidstatus_* files if you have Selinux enabled.
If everything was done right you will find new virtual host in your Zabbix inventory few minutes later named RaidMon - $ESXi_host_name. You can monitor any number of ESXi hosts with unique hostnames with one raidmon VM. Template will dicover them automatically by parsing raidstatus_* filenames found in /tmp directory.
This template supports multiple controllers per host. It will discover and monitor:
- controllers
- cache vault units
- BBU units
- logical discs
- physical discs installed in enclosures and backplanes
- physical discs NE - disks connected directly to contorller without enclosures and backplanes
Template was exported from Zabbix 6.4 and tested with Zabbix Agent 2 but it should work with conventional Zabbix Agent as well. Scripts have been tested on ESXi 7.0.
