New Relic + Wordpress - ignore wp-cron.php


New Relic + Wordpress - ignore wp-cron.php

我们已经在我们的服务器上安装了New Relic,以监控我们网站的性能。但是最近我们想从New Relic监控中删除wp-cron.php。

我将以下代码放入wp-cron.php:

[...]
if ( !defined('ABSPATH') ) {
/** Set up WordPress environment */
require_once('./wp-load.php');
}
if (extension_loaded('newrelic')) {
    newrelic_ignore_transaction();
    newrelic_ignore_apdex();
}
[...]

不幸的是,这段代码不起作用,New Relic仍然在报告中显示超时的wordpress cronjob。我们不需要知道在我们的wordpress应用程序中有多少cron作业消耗了时间。

有谁知道如何从新遗迹中移除它吗?

我发现在应用程序中为每个PHP应用程序或脚本设置变量的最佳方法是在PHP.ini中设置auto_prepend_file以指向为您设置这些变量的PHP文件。

我使用的代码是在git上发布的,请随意借用/改进/建议。为了简单起见,我在这里也列出了它:

###
# 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();
            }           
        }
}

如果你的服务器配置允许每目录php.ini,删除一个新的php.ini并让auto_prepend_file指向一个php文件,调用newrelic_ignore_transaction()

如果您的服务器配置不允许php.ini(例如mod_fcgid),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()

我对New Relic一无所知。多亏了你的问题,我发现它似乎是一个非常有用的工具。

检查周围,我发现Drupal的这个代码片段与cron作业有关。参见第68行TRUE参数。也许你需要……

Drupal模块实现New Relic

57 /**
58 * Implementation of hook_cron().
59 *
60 * This is used to set cron tasks to be not tracked by RPM if so desired.
61 */
62 function new_relic_rpm_cron() {
63     $cron_tracking = variable_get('new_relic_rpm_track_cron', 'norm');
64     if ($cron_tracking == 'bg') {
65         newrelic_background_job(TRUE);
66     }
67     elseif ($cron_tracking == 'ignore') {
68         newrelic_ignore_transaction(TRUE); // pass TRUE to ignore
69     }
70 }
