11 months ago Hello SNapier,
I suspect your machine has performance counters disabled or not properly configured. I have tested this endpoint on several machines and it is working on all of them.

11 months ago NCPA uses Python's psutil library to get memory information. Based on your error information, I'm pretty sure it has to do with the swap_memory() which goes down to psutil_swap_percent(). The performance counter used for this is \\Paging File(_Total)\\% Usage. In the performance monitor it should be listed as Paging File \ % Usage.
In all likelihood the problem is either that this counter doesn't exist or that performance counters are disabled.

11 months ago 2.4.1 "Silent" uninstall artifacts maybe?
This did not cleanly remove the NCPA service from the system. I had to manually remove the entry for NCPA from the registry.
When installed and configured with passive checks enabled only 3 of the deployed passive checks function. CPU DISK HOST
This is due to a failure in the API for Memory/Swap referenced by the check.
{ "swap": { "total": "Error retrieving child: 'PdhAddEnglishCounterW failed. Performance counters may be disabled.'", "free": "Error retrieving child: 'PdhAddEnglishCounterW failed. Performance counters may be disabled.'", "percent": "Error retrieving child: 'PdhAddEnglishCounterW failed. Performance counters may be disabled.'", "used": "Error retrieving child: 'PdhAddEnglishCounterW failed. Performance counters may be disabled.'" } }
