Sending errors to syslog in php-fpm

Question

I'm trying to setup an php-fpm daemon to send error_log to syslog.

My config php-fpm.conf looks thereby.

error_log = syslog
syslog.facility = local4
syslog.ident = php-fpm

Restarting php-fpm daemon I can see in the remote syslog server.

Mar 22 00:32:08 192.168.33.14 php-fpm[20919]: [NOTICE] configuration file /etc/php5/fpm/php-fpm.conf test is successful

Good!

But when I test this with a real php script with errors, message change to..

Mar 22 00:05:59 192.168.33.14 ool www[20889]: PHP Parse error:  syntax error, unexpected ''api'' (T_CONSTANT_ENCAPSED_STRING) in /var/api/public/index.php on line 2

ool www is pool + default pool name (www). So two questions:

• Why I see ool www instead of php-fpm (syslog.ident value)?
• Why is pool title is truncated?

Answer 1

I think its a PHP bug :( See please

Answer 2

This issue will become more prevalent as we start to upgrade older systems to php 5.5+, so posting for future reference.

Here is the fix we used, put it as low level as you can so all your scripts can benefit:

// This was needed for upgrade to php5.5+ with php-fpm

openlog('php', LOG_ODELAY, LOG_USER);
