We are trying to get disk usage data of Windows Servers using the Backend API GET objects/rrdexport

http://[HOST]/nagiosxi/api/v1/objects/rrdexport?apikey=[APIKEY]&pretty=1&host_name=[HOSTNAME]&service_description=Drive C: Disk Usage

But we're always getting the following error:

{
"error": "No valid data returned."
}

We are using the Nagios's Wizard for Windows Servers (xiwizard_windowsserver_nsclient_service).

We are sure that the data is there, since we can see it in the Nagios XI's interface.

All others Windows Servers services data (ping, cpu, memory, etc) are being obtained correctly.

Also, disk usage data for Linux Servers (service_description=/ Disk Usage) is being obtained correctly.

We have already tried "service_description=Drive_C:_Disk_Usage", "service_description=Drive_C_Disk_Usage" and even rename the service to "DriveCDiskUsage" and try "service_description=DriveCDiskUsage", but nothing worked.

Can anyone help us achieve this?

Thanks in advance!

If a host name or Service Description has a space in it, you will have to replace it with %20 so the curl command will treat it as a valid URL.
Try the example below and let us know if it works.
http://[HOST]/nagiosxi/api/v1/objects/rrdexport?apikey=[APIKEY]&pretty=1&host_name=[HOSTNAME]&service_description=Drive%20C:%20Disk%20Usage

Thank you for your answer!

I had already tried that. Sorry for not have mentioned.

I have also tried Drive%20C%3A%20Disk%20Usage (URL encode for the : too) and Drive+C%3A+Disk+Usage.

Looks like it's not a problem with the service name, since I tried renaming it to DriveCDiskUsage and it still didn't work.

f you can post the exact command you are using so I can view it?
If you are using curl, add the -v (Verbose) to the command and see if you get more details.
Also, one thing, make sure the user account that is tied to the the API key is an admin account that can view that host and service.
