Monitoring moodle server with nagios

פורסם ב: by

Nagios is a popular open source computer system and network monitoring software application. It watches hosts and services, alerting users when things go wrong and again when they get better. Nagios offers complete monitoring and alerting for servers, switches, applications, and services.There are plenty of ways you can monitor a server using nagios for example through ssh, nrpe or snmp. In this blog post I will be explaining monitoring parameters of an Ubuntu server running Moodle.

How to: Vote for and Follow tickets in the Moodle Tracker | Moodle News

פורסם ב: by

If you’re interested in following progress, it’s called “watching” an item. If you want to log your support of an issue you can “vote” for it. To get started you’ll need to jump over to https://tracker.moodle.org and make sure you have a username and password. It’s a great resource for finding what’s being worked on, contributing ideas and watching them progress through the stages of development or resolution.

SQL Fiddle

פורסם ב: by

SQL Fiddle. How does it work? The Schema DDL that is provided is used to generate a private database on the fly. If anything is changed in your DDL (even a single space!), then you will be prompted to generate a new schema and will be operating in a new database.  All SQL queries are run within a transaction that gets immediately rolled-back after the SQL executes. This is so that the underlying database structure does not change from query to query, which makes it possible to share anonymously online with any number of users (each of whom may be writing queries in the same shared database, potentially modifying the structure and thus — if not for the rollback — each other’s results).  As you create schemas and write queries, unique URLs that refer to your particular schema and query will be visible in your address bar. You can share these with anyone, and they will be able to see what you’ve done so far. You will also be able to use your normal browser functions like ‘back’, ‘forward’, and ‘reload’, and you will see the various stages of your work, as you would expect.

PHP on Google App Engine

פורסם ב: by

At Google IO this year, Google announced support for a new runtime running on App Engine, PHP. Currently, they have full support for languages such as Python, Java, and Go. PHP on App Engine was the number one request voted by developers and Google has finally delivered. PHP empowers a great percentage of the web sites in the world, it is very likely this will be taken out of Experimental mode soon into full Production mode. Google has taken the open source PHP 5.4 platform and augmented it to run on App Engine. They created a safe “sandboxed” environment for your apps.
