UPC Maintenance Monitor is an open source monitoring tool for scheduled maintenances of the hungarian cable provider UPC. It monitors the maintenance schedule webpage and emails you when a maintenance is scheduled for the town/city you provided.
See the example site: https://www.do01.r-us.hu/upc-karb/
- The idea started with an article of David Walsh
- The website parsing is using Simple HTML DOM
- The autocomplete functionality is using Alexander Farkas's Remote-List jQuery plugin
- The data source for autocomplete is provided by the hungarian postal services as an Excel workbook
- The autocomplete data generator is using SimpleXLSX class to process the Excel table from hungarian postal services, and generate a JSON array
- The subscription, and email notification code is based on Remy van Elst's certificate-expiry-monitor
- PHP 5.6+
- OpenSSL
- PHP must allow remote fopen.
Unpack, change some variables, setup a cronjob and go!
First get the code and unpack it to your webroot:
cd /var/www/html/
git clone https://github.com/gnanet/upc-maintenance-monitor.git
Create the database folder, outside of your webroot. If you create these inside your webroot, everybody can read them.
mkdir -p /var/www/upc-mm-db/
chown -R $wwwuser:$wwwgroup /var/www/upc-mm-db
These files are used by the tool as database for checks, on first access they will be created.
Change the location of these files in lib/settings.php:
// set this to a location outside of your webroot so that it cannot be accessed via the internets.
$datastore = '/var/www/upc-mm-db';
$pre_check_file = $datastore.'/upc_pre_checks.json';
$check_file = $datastore.'/upc_checks.json';
$deleted_check_file = $datastore.'/upc_deleted_checks.json';
Also change the $current_domain variable, it is used in all the email addresses.
$current_domain = "www.do01.r-us.hu";
And $current_link, which may or may not be the same. It is used in the confirm and unsubscribe links, and depends on your webserver configuration. example.com/subdir here means your unsubscribe links will start https://example.com/subdir/unsubscribe.php.
$current_link = "www.do01.r-us.hu/upc-maintenance-monitor";
Visit https://$current_link/lib/telepulesnevek.php one time, to generate the autocomplete data.
Set up the cronjob to run once a day:
# /etc/cron.d/upc-maintenance-monitor
1 1 * * * $wwwuser $(which php) /var/www/html/upc-maintenance-monitor/cron.php >> /var/log/upc-maintenance-monitor.log 2>&1
The default timeout for checks is 2 seconds. If this is too fast for your internal services, this can be raised in the lib/settings.php file.
