OSMC 2022 | check_vsphere by Danijel Tasov
Currently the two dominant check scripts for VMware/Vsphere are check_vmware_esx and check_vmware_api. But they have a problem: they are based on the Perl SDK provided by VMware, which they have deprecated. You may already see problems when checking against newer VMware installations. So, we need a plugin in a different language. That’s why I started a new plugin written in Python using the Python SDK which is not deprecated. While doing this I also studied the check_vmware_esx/api and found out that they actually doing a very bad job with metrics based checks. Also, the VMware API is… well… let’s say over-engineered. So, this talk is about what I’ve learned during the implementation, what the current plugins do wrong, the overengineered VMware API and what the current state of the new plugin is.
