+**Before actually creating a new issue**
+I confirm, I have read the FAQ (https://www.claudiokuenzler.com/blog/308/check-esxi-hardware-faq-frequently-asked-questions): Y/N
+I confirm, I have restarted the CIM server (` /etc/init.d/sfcbd-watchdog restart `) on the ESXi server and the problem remains: Y/N
+I confirm, I have cleared the server's local IPMI cache (`localcli hardware ipmi sel clear`) and restarted the services (`/sbin/services.sh restart`) on the ESXi server and the problem remains: Y/N
+
+**Describe the bug**
+A clear and concise description of what the bug is. 
+
+**Show the full plugin output, including the command with -V parameter**
+Run the plugin with `-V` parameter and show the full output (including command) here. Obviously obfuscate credentials.
+
+**Expected behavior**
+A clear and concise description of what you expected to happen.
+
+**Versions:**
+ - check_esxi_hardware plugin: 
+ - VMware ESXi:
+ - pywbem: 
+ - Python:
+ - Third party tools (Dell OMSA, HP Offline Bundle, etc):
