Plugin:cURL-JSON/phpfpm

This page contains some example configurations for the cURL-JSON plugin. This page is meant as a cookbook, so if you have a configuration for an aspect not handled here or a daemon not present, please feel free to add anything that's useful for you.

You can use cURL-JSON plugin plugin to collect stats from php-fpm instances. The example of config is below.

Config

LoadPlugin curl_json
<Plugin curl_json>
<URL "http://127.0.0.1/_fpmstatus?json">
 Instance 'main'
 <Key "accepted conn">
     Type "phpfpm_requests"
     Instance ""
 </Key>
 <Key "slow requests">
     Type "phpfpm_slow_requests"
     Instance ""
 </Key>
 <Key "listen queue">
     Type "phpfpm_listen_queue"
     Instance ""
 </Key>
 <Key "active processes">
     Type "phpfpm_processes"
     Instance "active"
 </Key>
 <Key "total processes">
     Type "phpfpm_processes"
     Instance "total"
 </Key>
</URL>
</Plugin>

Please note that the metod used to access php-fpm stats is not FastCGI but HTTP. So you need to configure your web-server to pass such requests to php-fpm instance. You can check your web-server configuration using "curl". You had to get something similar to:

#curl http://127.0.0.1/_fpmstatus?json
{"pool":"pool_name","process manager":"dynamic","start time":1562671972,"start since":347271,"accepted conn":1082924,"listen queue":0,"max listen queue":0,"listen queue len":0,"idle processes":4,"active 
processes":1,"total processes":5,"max active processes":25,"max children reached":8,"slow requests":0}

Types

You'll need to create a custom types.db and add these types:

# types.db
phpfpm_listen_queue  value:GAUGE:0:65535
phpfpm_processes     value:GAUGE:0:65535
phpfpm_requests      value:DERIVE:0:U
phpfpm_slow_requests value:DERIVE:0:U

See `TypesDB' configuration option in collectd config file for locations of default and custom `types.db' files.
