I haven't installed anything on the webservers (yet), but I do wish to via
snmp do load, cpu, etc. or if there is a better way like a client daemon,
feel free to let me know. I am still reading/understanding what each is used
for (service.cfg, commands.cfg, etc.) but I have the following all for that
check;
services.cfg
define service {
service_description check_s1
use generic-service
hostgroup_name s1_WebServers
check_command check_s1!3!5
}
check_commands.cfg
define command {
command_name check_s1
command_line $USER1$/check_http -H
www.site1.com-w "$ARG1$" -c "$ARG2$"
}
command.cfg has;
command[check_s1]=/usr/local/groundwork/nagios/libexec/check_http -H
www.site1.com -I $HOSTADDRESS$
As for where the local command was run, yes it was local to the groundwork
(nagios) server from the following location;
root at groundwork:/usr/local/groundwork/nagios/libexec/check_http -H
www.site1.com -I 192.168.50.101
HTTP OK HTTP/1.1 200 OK - 14351 bytes in 0.249 seconds
|time=0.249456s;;;0.000000 size=14351B;;;0
I am not sure what the NRPE plugin is but just looking at the options, it
looks like it's run on the client as there is no spot for IP, when run local
it simply says connection refused by host for the site1.com domain.
Thanks.
