The scheduling features of this plugin are only available in the Professional release. The Core release does need the plugin to be enabled for the SEO and Link Tools features to work. |
The "System - Admin Tools" plugin implements all of the features of Admin Tools that run automatically. This includes the Web Application Firewall and the URL redirections as well as scheduled tasks such as scheduled table maintenance or periodic import of settings from a master server.
You can access the plugin's configuration parameters by going to your site administrator backend, , . Find the item System - Admin Tools on the list and click on it. The standard Joomla! plug-in configuration page opens.
On the right-hand side of the administrator area you can find the standard Joomla! controls. First, make sure that Enabled is set to Yes. Then, in order for the plugin to be published in the correct order, select 0 - First from the Order drop-down list.
Rescue Mode
The Rescue Mode allows Super Users of the site to quickly unblock themselves if their IP address is accidentally blocked.
- Rescue URL (Joomla! 3.6 or later only)
-
When enabled (default) the Rescue Mode feature is enabled, allowing Super Users with blocked IPs to request a temporary Rescue URL which lets them log into the site and lift the block. We recommend leaving this feature enabled unless you know what you are doing. See the Rescue Mode section for more information.
![[Important]](/media/com_docimport/admonition/important.png)
Important You will only receive the email to activate Rescue Mode if your IP is being blocked by Admin Tools. If your IP is NOT blocked by Admin Tools you will NOT receive any email. This is by design. It doesn't make sense to temporarily unblock yourself with Rescue Mode when you are not blocked!
- Rescue duration (minutes)
-
How long is the Rescue Mode active. This controls two things:
-
The maximum amount of time between requesting a Rescue URL and visiting it.
-
The maximum amount of time between visiting the Rescue URL and the end of Rescue Mode.
We recommend leaving this setting to 15 minutes. Lower values tend to be very impractical.
-
Blocked requests reporting
The following options determine how Admin Tools handles and reports blocked requests.
- Email language
-
Admin Tools will send you emails to notify you of blocked requests when you enter an email address in WAF Configuration. By default, the current user's language (or your site's default language, if no user is currently logged in) is being loaded, which means that these emails will be sent out in this language. If you have a multilingual website it means that you may receive an email in any language available in your site. This can lead to confusion and makes it nigh impossible to set up any email filters. Therefore we give you this option. You can enter the language tag of the language in which you wish those blocked requests emails to be sent. For example, typing
en-GBin this field will cause all emails to be sent out in English. If left blank (default) the current language loaded by Joomla! will be used. - Maximum block requests log entries
-
Specify the maximum number of entries to keep in the blocked requests log. Excess records will be deleted. Use 0 to turn off this feature and keep all blocked requests log entries (recommended).
Note If you have thousands of old entries it will take a while for Admin Tools to remove all of the old entries. Old records are deleted in 100 record batches on each page load for performance reasons.
Scheduled maintenance
The System - Admin Tools plugin allows you to automate some basic maintenance of your site.
- Enable Session Optimizer
-
When enabled, the Session Optimizer will be scheduled to run automatically. This feature will repair and optimize Joomla!'s sessions table.
- Run every X minutes
-
How often to run the Session Optimizer feature, in minutes
- Enable Session Cleaner
-
When enabled, the Session Cleaner will be scheduled to run automatically. This feature will purge (completely empty) and optimize Joomla!'s sessions table. Watch out! This will automatically log all users out of your site! You should only use it on sites where you don't expect to have logged in users at all, e.g. a company presentation site.
- Run every X minutes
-
How often to run the Session Cleaner feature, in minutes
- Enable Cache Cleaner
-
When enabled, the Cache Cleaner will be scheduled to run automatically. This feature will try to purge (completely empty) Joomla!'s cache. This is not possible on occasions, especially if you are using a cache adapter which doesn't support purging.
- Run every X minutes
-
How often to run the Cache Cleaner feature, in minutes
- Enable Cache Auto-expiration
-
When enabled, the Cache Auto-expiration will be scheduled to run automatically. This feature will try to expire and delete stale items in Joomla!'s cache. Unlike the Joomla! built-in feature, it will try to run this operation across all caches. This is not possible on occasions, especially if you are using a cache adapter which doesn't support automatic expiration control.
- Run every X minutes
-
How often to run the Cache Auto-expiration feature, in minutes
- Delete inactive users
-
When this option is enabled, the Admin Tools plugin will automatically delete inactive users, i.e. users who registered on the site but never logged in. On each page load, up to five inactive users will be deleted, to avoid slowing down your site. There are four different options:
- Never
-
Disables this feature
- Only if they haven't activated their account
-
Users who have never activated their account will be removed. If they have activated their account they will not be removed.
- Only if they activated, but never logged in
-
Users who have activated their account but never logged in will be removed. If they haven't activated their account yet, they will not be removed.
- Activated or not, as long as they haven't logged in
-
Any user who hasn't logged in for the number of days specified in the next option will be removed from the site, no matter if he has activated his account or not.
- Delete after this many days
-
How many days must elapse between the registration date of an inactive user and its deletion. For example, if this option is set to 7 then if a user registers on your site on the 1st of the month and has not logged in at least once by the eighth of the month, his user account will be removed.
All scheduling and expiration options are assessed on a best-effort bases. This means that they will try to run every X minutes, but only as long as there is enough visitor traffic on your site to trigger them. In any other case they will defer their execution for when there is visitor traffic.
Automatic settings import (“Sync server”)
Some larger / busier web agencies tend to have dozens to hundreds of sites which use roughly the same mix of extensions. In these cases a small tweak in the Admin Tools setup of one site usually has to be propagated to every other site in their portfolio. This can be a tedious process.
Admin Tools gives you the option to have a “sync server” of shorts. The idea is that you will have a JSON file with Admin Tools settings in a URL that's publicly accessible. Every so often your sites will check out this URL and import the settings. This URL could be on your web server, a Dropbox account, an S3 bucket and so on.
The JSON file in that URL can be generated by going to Admin Tools' Import/Export Settings page. The idea is that you modify the configuration of one site and export its settings in a JSON file. You can edit that file if necessary. Then upload it to where it can be found using the public URL you've configured on all other sites. Wait for the requisite number of hours to pass and now all your sites have been synced to those settings.
The relevant settings for each site are:
- Automatic import URL
-
URL pointing to Admin Tools JSON settings that should be imported.
- Automatic import frequency (hours)
-
How often (in hours) to read the remote URL and import its contents into the Admin Tools installation
