-h, --help

print this help message
|
||
-H, --hostname=HOST
|
||
name or IP address of host to check
|
||
-p, --port=PORT
|
||
Http port, or Fastcgi port when using --fastcgi
|
||
-u, --url=URL
|
||
Specific URL (only the path part of it in fact) to use, instead of the default "/fpm-status"
|
||
-s, --servername=SERVERNAME
|
||
ServerName, (host header of HTTP request) use it if you specified an IP in -H to match the good Virtualhost in your target
|
||
-f, --fastcgi
|
||
Connect directly to php-fpm via network or local socket, using fastcgi protocol instead of HTTP.
|
||
-U, --user=user
|
||
Username for basic auth
|
||
-P, --pass=PASS
|
||
Password for basic auth
|
||
-r, --realm=REALM
|
||
Realm for basic auth
|
||
-d, --debug
|
||
Debug mode (show http request response)
|
||
-t, --timeout=INTEGER
|
||
timeout in seconds (Default: $o_timeout)
|
||
-S, --ssl
|
||
Wether we should use HTTPS instead of HTTP. Note that you can give some extra parameters to this settings. Default value is 'TLSv1'
|
||
but you could use things like 'TLSv1_1' or 'TLSV1_2' (or even 'SSLv23:!SSLv2:!SSLv3' for old stuff).
|
||
-x, --verifyssl, --verifyhostname
|
||
verify certificate and hostname from ssl cert, default is 0 (no security), set it to 1 to really make SSL peer name and certificater checks.
|
||
'verifyhostname' is the old deprecated name of this option.
|
||
-X, --cacert
|
||
Full path to the cacert.pem certificate authority used to verify ssl certificates (use with --verifyssl).
|
||
if not given the cacert from Mozilla::CA cpan plugin will be used.
|
||
-w, --warn=MIN_AVAILABLE_PROCESSES,PROC_MAX_REACHED,QUEUE_MAX_REACHED
|
||
number of available workers, or max states reached that will cause a warning
|
||
-1 for no warning
|
||
-c, --critical=MIN_AVAILABLE_PROCESSES,PROC_MAX_REACHED,QUEUE_MAX_REACHED
|
||
number of available workers, or max states reached that will cause an error
|
||
-1 for no CRITICAL
|
||
-V, --version
|
||
prints version number
|
||
|
||
Note :
|
||
3 items can be managed on this check, this is why -w and -c parameters are using 3 values thresolds
|
||
- MIN_AVAILABLE_PROCESSES: Working with the number of available (Idle) and working process (Busy).
|
||
Generating WARNING and CRITICAL if you do not have enough Idle processes.
|
||
- PROC_MAX_REACHED: the fpm-status report will show us how many times the max processes were reached sinc start,
|
||
this script will record how many time this happended since last check, letting you fix thresolds for alerts
|
||
- QUEUE_MAX_REACHED: the php-fpm report will show us how many times the max queue was reached since start,
|
||
this script will record how many time this happended since last check, letting you fix thresolds for alerts
|
||
|
||
Examples:
|
||
|
||
This will lead to CRITICAL if you have 0 Idle process, or you have reached the max processes 2 times between last check,
|
||
or you have reached the max queue len 5 times. A Warning will be reached for 1 Idle process only:
|
||
|
||
check_phpfpm_status.pl -H 10.0.0.10 -u /foo/my-fpm-status -s mydomain.example.com -t 8 -w 1,-1,-1 -c 0,2,5
|
||
|
||
this will generate WARNING and CRITICAL alerts only on the number of times you have reached the max process:
|
||
|
||
check_phpfpm_status.pl -H 10.0.0.10 -u /foo/my-fpm-status -s mydomain.example.com -t 8 -w -1,10,-1 -c -1,20,-1
|
||
|
||
theses two equivalents will not generate any alert (if the php-fpm page is reachable) but could be used for graphics:
|
||
|
||
check_phpfpm_status.pl -H 10.0.0.10 -s mydomain.example.com -w -1,-1,-1 -c -1,-1,-1
|
||
check_phpfpm_status.pl -H 10.0.0.10 -s mydomain.example.com
|
||
|
||
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
