Performance

This module is a very lightweight module that logs the peak php memory usage to the watchdog.

Provides configurable set of rule actions to check the availability of predefined sites.

Provision New Relic is a backend Drush module built for the AEgir Hostmaster/Provision system. This is only for use with provision, the backend component of AEgir. It does not provide any front-end tasks to Hostmaster.

New Relic is the all-in-one web application performance tool that lets you see performance from the end user experience, through servers, and down to the line of application code.

This drush extension adds a small snippet of code to each site's virtual host file, allowing newrelic to identify each site as a different application.

Installation

• The first step is to setup newrelic to monitor PHP application on the AEgir server - https://newrelic.com/docs/php/new-relic-for-php
• Download and unpack this module into ~/.drush directory for aegir (folder structure will probably look something like this - /var/aegir/.drush/provision_newrelic)
• Reverify any existing sites to update their virtual host settings. New sites will be setup with newrelic.

Notes/Considerations

Alternative implemention of field_sql_storage core module:

Automatic database slave selection

This database driver (called "autoslave") will automatically use the database slaves where applicable and otherwise use a master database.

where applicable means:

1. The query is not a write query (and not a select query with locking)
2. The tables in the query have not been written to during the request and within the assumed replication lag
3. A transaction has not been started
4. The tables in the query are not specified in the 'tables' option in the driver settings
5. A lock has not been started (core db-lock and memcache-lock supported)

Small module to force page refreshes when authenticated users visit a page that has been cached on the client side prior to login.
