我发现为每个 PHP 应用程序或应用程序中的脚本设置变量的最佳方法是在 PHP.ini中设置auto_prepend_file以指向为您设置所述变量的 PHP 文件。
我使用的代码发布在 git 上,请随意借用/改进/建议。为了简单起见,我也在这里列出它:
###
# NewRelic PHP API central file
# Description: Allows PHP installs using mod-fgcid to set newrelic_set_appname
# Usage: Inside PHP.ini for each vhost in your server,
# point to this script using: auto_prepend_file = "newrelic.php"
# Where you place the script depends on your include_path setting.
# See http://www.php.net/manual/en/ini.core.php#ini.auto-prepend-file

if (extension_loaded('newrelic')) {
if (!isset($_SERVER['HTTP_HOST'])) {
newrelic_set_appname ("Unknown");
} else {
# If UseCanonicalName is set to Off, Apache will use (user inputted) HTTP_HOST for SERVER_NAME
# Best is to rely on HTTP_HOST and validate it against a list of allowed hosts.
# See http://shiflett.org/blog/2006/mar/server-name-versus-http-host
$host = strtolower($_SERVER['HTTP_HOST']);
# Easily disable any vhost from sending data to newrelic.
$disabled_hosts = array('foo.example.com');
$valid_hosts = array('bar.example.com');
# Add a secondary AppName
$secondary_appname = ';All Virtual Hosts';
if ((!in_array($host, $disabled_hosts)) && (in_array($host, $valid_hosts))) {
newrelic_set_appname($host.$secondary_appname);
} else {
newrelic_ignore_transaction();
# technically you wouldn't need to disable_autorum when you ignore_transaction, but it's good practice.
newrelic_disable_autorum();
}
}
}
如果您的服务器配置允许每个目录 php.ini,请删除一个新的 php.ini 并让 auto_prepend_file 指向一个调用newrelic_ignore_transaction()的 php 文件。
如果您的服务器配置不允许每个目录 php.ini(例如使用 mod_fcgid),请修改建议的代码以检测正在运行的脚本并在满足该条件时发出newrelic_ignore_transaction() 。
