Hello Rostyslav,

Can someone to help me configure monitoring PHP-FPM, please?

What parts of PHP-FPM are you trying to monitor?

I am novice with Sensu and I do not know how to write properly .json to
php-fpm.

I would start with the check-proccess[1] check and monitor for the pid file.

Please tell us what you can't do exactly, so we can help you the best we can.

[1] GitHub - sensu-plugins/sensu-plugins-process-checks: This plugin provides native process instrumentation for monitoring and metrics collection, including: process status, uptime, thread count, and others.

Regards,

···

If you want to monitor anything with Sensu, the easiest thing you can do is find any command that works on the command-line, and configure a Sensu check with that command. Something like “curl http:127.0.0.1/somepath” is probably the simplest thing that could work. Looks like there is a community plugin that you could probably hook up (https://github.com/sensu-plugins/sensu-plugins-php-fpm).

Looking at the “Example Check Definition” here might get you started with creating a check definition in JSON.

Good luck!

Thank you for answers.

I have created php-fpm.json but I am not sure that it is properly json file, because I have seen in Ushiva nothing.
I would like to check is php-fpm available, pass to Graphite statistic. An, if it possible, monitor and collect statistics by pool. An get alert for 50x error, if they appeared.

{
“checks”: {
“phpfpm_check”: {
“command”: “/etc/sensu/plugins/check_php-fpm.rb”,
“interval”: 30,
“subscribers”: [“webserves”],
“handlers”: [“graphite”]
},
“phpfpm_metrics”: {
“type”: “metric”,
“command”: “/etc/sensu/plugins/php-fpm-metrics.rb”,
“interval”: 10,
“subscribers”: [“webserves”],
“handlers”: [“graphite”]
}

``

}
}

Thank you advance for support.

That looks like a good start. There is a bit to get your head around when starting.

One thing that jumps out is the check-php-fpm.rb plugin being sent to the “graphite” handler. Generally, you’d want to handle metrics differently than checks, so you’d want some handler that sent the alert to PagerDuty, or your cell phone, or whatever.

Can you create a gist (gist.github.com), showing

The output of “sudo -u sensu /etc/sensu/plugins/php-fpm-metrics.rb” from one of your web servers
The output of “sudo -u sensu /etc/sensu/plugins//check_php-fpm.rb” from one of your web servers
The JSON definitions of your handlers (i.e. “graphite”).

Also, a screenshot of your Uchiwa “checks” and “clients” pages, with sensitive information blurred?

Good luck!

Cool, so you’re want to debug why those commands are not outputting correctly. Looks like it is a load issue with https://rubygems.org/gems/crack/versions/0.4.2, so you’ll want to make sure that is installed with gem and being loaded correctly.
