This blog posting is a tutorial that walks through setting up a Nagios passive check that can be securely updated with WGET or CURL.
This blog posting demonstrates a method to set the SyntaxHighlighter container size using JavaScript which can be useful for showing long blocks of code that you want the user to scroll through to see.
The container size can be set using CSS but it's not always practical to change for one-off adjustments. The example below adds an event loops that waits for SyntaxHighlighter to generate the formatted code. When the formatted code is generated its container height is set and the event loop is removed.
Launching OpenInsight oinsight.exe sometimes displays an Application Manager error 'Unable to load language resource dll!'. This article presents one possible cause and solution to this problem.
If you're using Ubuntu 12 LTS "Precise Pangolin" with the Nagios 3.4.1 package from the Ubunutu repository and you're having trouble with passive checks and the freshness_threshold directive you may want to consider upgrading Nagios.
This blog post demonstrates an easy way to utilize Mailgun for checking bounced email messages sent through the Mailgun managed email service. With a few bits of information from your free Mailgun account you can begin checking if your messages were delivered. This blog post continues where Mailgun and OpenInsight: Getting Started ended so if you're not familiar with Mailgun or why it's incredibly useful I encourage you to review the post before continuing on.
SyntaxHighlighter is a JavaScript tool for dynamically adding syntax highlights to code displayed on web pages. This blog post will show you how to apply code highlighting to OpenInsight Basic+ code using SyntaxHighlighter and a custom plugin from the SyntaxHighlighterForOpenInsight GitHub project.
Email is easy but using email effectively is hard. It's easy for an OpenInsight developer to use the rti_cdomail function to send an email message without concern for what happens to the message after the function returns. The process becomes a lot more difficult when the developer must deal with:
Un-subscription link tracking and response
Verifying message delivery from within code
Handling bounced messages
Each client site having a different mail server configuration
Bad email reputation delaying message delivery
With enough time and resources each of these challenges can be addressed by the developer and staff resources but the goal of this article is to leverage existing email services for use in OpenInsight to address these problems and reduce the use of staff resources to manage email.
