Nagios Support Forum

Can you post a screenshot or the full output including the command you typed (in a code block).

this is my commands.cfg

define command{
command_name check_snmp_synology
command_line $USER1$/check_snmp_synology -H $HOSTADDRESS$ -v $ARG1$ $ARG2$
}


This is my Service.cfg file

define host{
use dev
host_name Hostname
address 192.168.1.77:5000
max_check_attempts 3
check_interval 3
retry_interval 1
notifications_enabled 1

}

define service{
Use generic-service
host_name Hostname
service_description System Fan Status
check_command check_synology!Check system Fan status
active_checks_enabled 1 ; Active service checks are enabled
passive_checks_enabled 1 ; Passive service checks are enabled/accepted
max_check_attempts 5
check_interval 5
retry_interval 1
}




define service{
use generic-service
host_name Hostname
service_description Disk Status
check_command check_synology!Check all disk status
active_checks_enabled 1 ; Active service checks are enabled
passive_checks_enabled 1 ; Passive service checks are enabled/accepted
max_check_attempts 5
check_interval 5
retry_interval 1

This is what is showing on the nagios site. next to the service command is showing in error

(No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_synology, ...) failed. errno is 2: No such file or directory

OK so I must re-iterate what I said earlier:

As per my instructions you need to execute the plugin in a terminal session on your Nagios Core server. This will show us if the plugin works, if it doesn't work we'll troubleshoot why.

After we know it works you will configure Nagios.

when i run this command

/usr/local/nagios/libexec/check_snmp_synology -2 public -h your_synology_ip_address

No such file or directory

permission denied

OK so it sounds like the plugin is not in that location.

What is the output of :
If you downloaded it to a different location then you will need to change that directory in the test command and try again.

What is the output of :

Code: Select all

ls -la /usr/local/nagios/libexec/check_snmp_synology

If you downloaded it to a different location then you will need to change that directory in the test command and try again.

I get this

17585 may 21 13:08 /usr/local/nagios/libexec/check_snmp_synology

Note I just copied the file over and ran this command

chmod +x /usr/local/nagios/libexec/

Here is a screen shot

OK great, we now need to make it executable (I made a mistake with my original command):
Now try and test the plugin, what output does it produce?

after i made it executable i ran this

./check_snmp_synology -2 public -h Ipaddress

results

CRITICAL - Problem with SNMP request, check user/password/host

Did you supply a username and password when you executed the command?
