Using this configuration:
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Read metrics of phpfpm, via HTTP status page or socket
|
||||
[[inputs.phpfpm]]
|
||||
## An array of addresses to gather stats about. Specify an ip or hostname
|
||||
## with optional port and path
|
||||
##
|
||||
## Plugin can be configured in three modes (either can be used):
|
||||
## - http: the URL must start with http:// or https://, ie:
|
||||
## "http://localhost/status"
|
||||
## "http://192.168.130.1/status?full"
|
||||
##
|
||||
## - unixsocket: path to fpm socket, ie:
|
||||
## "/var/run/php5-fpm.sock"
|
||||
## or using a custom fpm status path:
|
||||
## "/var/run/php5-fpm.sock:fpm-custom-status-path"
|
||||
##
|
||||
## - fcgi: the URL must start with fcgi:// or cgi://, and port must be present, ie:
|
||||
## "fcgi://10.0.0.12:9000/status"
|
||||
## "cgi://10.0.10.12:9001/status"
|
||||
##
|
||||
## Example of multiple gathering from local socket and remove host
|
||||
## urls = ["http://192.168.1.20/status", "/tmp/fpm.sock"]
|
||||
urls = ["http://localhost/status"]
|
||||
```
|
||||
[phpfpm]
|
||||
# An array of address to gather stats about. Specify an ip on hostname
|
||||
# with optional port and path. ie localhost, 10.10.3.33/server-status, etc.
|
||||
#
|
||||
# We can configure in three modes:
|
||||
# - unixsocket: the string is the path to fpm socket like
|
||||
# /var/run/php5-fpm.sock
|
||||
# - http: the URL has to start with http:// or https://
|
||||
# - fcgi: the URL has to start with fcgi:// or cgi://, and socket port must present
|
||||
#
|
||||
# If no servers are specified, then default to 127.0.0.1/server-status
|
||||
urls = ["http://localhost/status", "10.0.0.12:/var/run/php5-fpm-www2.sock", "fcgi://10.0.0.12:9000/status"]
|
||||
```
|
||||
|
||||
When run with:
|
||||
|
||||
```
|
||||
./telegraf --config telegraf.conf --input-filter phpfpm --test
|
||||
```
|
||||
|
||||
It produces:
|
||||
|
||||
```

|
||||
```
|
||||
|
||||
## Note
|
||||
|
||||
When using `unixsocket`, you have to ensure that telegraf runs on same
|
||||
host, and socket path is accessible to telegraf user.
