we have seen that check_nt is having some limitations so that you suggest on check_ncpa.
Now if i run the command check_nt with different scopes i am able to get the data. Please find the below.

I thought that ncpa is more capability than nsca. But ncpa is also not giving the output for multiple scopes. I understand you have some limitation but we have to resolve this.

Even if we call "/usr/local/nagios/libexec/check_ncpa.py -H 172.31.94.235 -t Test@123 -P 5693 -M 'plugins/dhcpncpa.ps1' -q "args=-all"


All scopes are not showing in nagios console.

Does ncpa does not have capabilities to call multiple scopes ? or plugin does not have capabilites?

In one of the previous posts you showed us "check_DHCP_perscope" defined this way: So, is check_DHCP_perscope.ps1 (that you are calling via check_nrpe and NSClient++) and dhcpncpa.ps1 (that you are calling via check_ncpa.py) the SAME script?

Can you upload the script that you are using on the forum?

Hi team,

Yes, the script is same as you suggest i am working on ncpa instead of nsca as its have some limitation. The script is also same.

Can you upload the script that you are using on the forum?

Hi Please find the attachment for the script.

There is a problem with the comma as a seperator in the way NCPA works, but I did create a workaround for you

attached is the text for a slightly modified dhcpncpa.ps1 which uses a semi-colon as a separator
