Nagios Support Forum

We have rebuild the whole server of our Nagios machine. VMware ESX VSphere is not working properly anymore.
One server have VMWare Host Current CPU Usage and Memory Usage error, "UNKNOWN: Host system ' ' not found". I have edited check_vmware_config_vcenter01 already but it still the same.
The other server have "No MEM fairness data" and "No CPU fairness data" message.
Please help how to fix this. Thanks.

Did you reinstall the SDK as per our documentation? A standard Nagios installation does not include that due to licensing issues. You can also take a look at Troy Lea's new VMWare monitoring wizard which is much faster:
