And this one is a basic starting example :
|
||||
|
||||
check_phpfpm_status.pl -H 127.0.0.1 -s nagios.example.com -w 1,1,1 -c 0,2,2
|
||||
|
||||
All these examples used an HTTP proxy (like Nginx or Apache) in front of php-fpm. If php-fpm is listening on a tcp/ip socket
|
||||
you can also make a direct request on this port (9000 by default) using the fastcgi protocol. You'll need the FastCGI client
|
||||
tools enabled in Perl (check the README) and the command would use the -f or --fastcgi option (note that SSL or servername
|
||||
options are useless in this mode).
|
||||
This can be especially usefull if you use php-fpm in an isolated env, without the HTTP proxy support (like in a docker container):
|
||||
|
||||
check_phpfpm_status.pl -H 127.0.0.1 --fastcgi -p 9002 -w 1,1,1 -c 0,2,2
|
||||
|
||||
HTTPS/SSL:
|
||||
|
||||
Adding --ssl you can reach an https host:
|
||||
|
||||
check_phpfpm_status.pl -H 10.0.0.10 -s mydomain.example.com --ssl
|
||||
|
||||
Check --verify-ssl (false by defaut) --cacert and --sl for more options, like below
|
||||
(note that certificate checks never wortked on my side, add -d for full debug and
|
||||
tell me if it worked for you, you may need up to date CPAN adn openSSL libs)
|
||||
|
||||
check_phpfpm_status.pl -H 10.0.0.10 -s mydomain.example.com --ssl TLSv1_2 --verify-ssl 1 --cacert /etc/ssl/cacert.pem
