WMI Monitor CPU Usage error

[slocrystal]

I have just setup our instance of Nagios and have been trying to use the WMI and nagios client features with no luck. The below error is what I receive when trying to use the wmi monitor for cpu usage. Any ideas.

UNKNOWN: Could not retrieve all required data. Failed to bind to uuid 4d9f4ab8-7d1c-11cf-861e-0020af6e7c57 - NT_STATUS_NET_WRITE_FAULT

Can you run these commands from the command line:

Code: Select all

cd /usr/local/nagios/libexec
./check_wmi_plus.pl -H <your_windows_machine_IP_address> -u <username> -p i <password> -m checkdrivesize -a c: -w 80 -c 95

and post the output?

Note: You can remove the sensitive info.

Output is as follows:

Are you sure that you are providing the right credentials? Also, if you are using a "typical" windows login, such as: "domain\username", try this: "domain/username" or "domain\/username", instead and see if it is going to work.

[slocrystal]

I have tried the credentials with both the / and \. I am using my domain admin credentials as well. I have confirmed that the target machine as well has the WMI-in and WMI-DCOM-In firewall rules enabled and set to allow.

[scottwilkerson]

actually as seen here

it should be

Code: Select all

domain/\username

as in

Code: Select all

./check_wmi_plus.pl -H xxx.xxx.xxx.xxx -m checkcpuq -u domain/\Nagios -p password

[slocrystal]

Looks like the /\ did the trick. I have confirmed within the services in the http console as well.

Do you guys recomend the nsclient++ or the wmi monitoring for most success?

Thanks.

Excellent.

This depends on what you are trying to accomplish and what you wall want to monitor. WMI is fine, except lack some of the features that NSClient++ has.
