Script Documentation:
=====================
Usage: ./check_phpfpm_status.pl -H <host ip> [-p <port>] [-s servername] [-t <timeout>] [-w <WARN_THRESOLD> -c <CRIT_THRESOLD>] [-V] [-d] [-u <url>] [-U user -P pass -r realm]
-h, --help
print this help message
-H, --hostname=HOST
name or IP address of host to check
-p, --port=PORT
Http port
-u, --url=URL
Specific URL to use, instead of the default "http://<hostname or IP>/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
-S, --ssl
Wether we should use HTTPS 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: 15)
-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
