Nagios Support Forum

Hi,
I'm using Nagios 4.0.6.
I tried with changing the check command of a host using nagios external command CHANGE_HOST_CHECK_COMMAND. But it is showing "Error: External command failed -> CHANGE_HOST_CHECK_COMMAND;localhost;check_tcp!22". I also tried with changing the service check. But it is also unsuccessful showing "Error: External command failed -> CHANGE_SVC_CHECK_COMMAND;localhost;SSH;check_SSH!70!90". There are no other traces of reason for this error.

Anybody having idea of why it failed?

How are you submitting the command? Is it terminated with a newline? Are you making sure to put the timestamp before the command?

Yes.. I have terminated with a newline and also added timestamp before the command. But still it shows the same error.

Do you have a regular file as the command pipe, or a proper command pipe?

Can you show us a specific example of what you're putting into the command pipe? I'd like to see the format and specific date stamp.

Do you have a follow up for us OP?
