Send email alerts from NXLog using Python, Perl, or Ruby

NXLog is a versatile log collector that easily integrates with other software, platforms, and programming languages. Out-of-the-box it supports integration with many third-party solutions through its input, output, and extension modules. Moreover, extending NXLog with custom functionality is as easy as writing an application or script in your favorite programming language and loading it from the configuration. Email notifications of events indicating potential security breaches or severe application errors are a standard procedure for IT admins and DevOps engineers.

The benefits of log aggregation

Logs are a record of the internal workings of a system. Nowadays, organizations can have hundreds and, more regularly, thousands of managed computers, servers, mobile devices, and applications; even refrigerators are generating logs in this Internet of Things era. The result is the production of terabytes of log data—event logs, network flow logs, and application logs, to name a few—that must be carefully sorted, analyzed, and stored. Without a log management tool, you would need to manually search through many directories of log files on each system to access and extract meaning from these millions of event logs.

The consequence of this narrow field of view is that you are not benefitting from the valuable information that other Event IDs used for security audit policies can offer.

How NXLog can help meet compliance mandates

Compliance mandates are frameworks that organizations must implement to meet industry regulations. Some of these mandates provide guidelines and best practices, while others may be tied to legislation. With the constant and rapid changes in technology, ensuring that your organization adheres to the relevant regulations is an ongoing process. So why should you comply? Simply put, not complying might cost you more than implementing processes to meet regulatory requirements. By not complying, you might be violating the law, and in case of a data breach, you may face litigation from affected parties.
