  Before you begin

  The healthcheck option was added to syslog-ng-ctl in version 4.2. You need this or a later syslog-ng version to use this option. It is already available in the most recent GNU/Linux distributions. If you use an LTS GNU/Linux distribution, then check https://syslog-ng.org/3rd-party-binaries/ for 3^rd party repositories for your OS.

  If you want to send latency values printed by syslog-ng-ctl to Elasticsearch, you also need the jo utility: https://github.com/jpmens/jo This is available in several GNU/Linux distributions.

• James G ☛ Technical Writing Chat with Nathan Driver

  This is the second interview in Technical Writing Chats, a series where I speak with technical writers about their day-to-day role and how they got started in their career. Today's interview is with Nathan Driver, a Technical Writer for the UK Government Digital Services team. I sincerely hope you enjoy!

  I'm a technical writer at Government Digital Service (GDS) in the UK government. Within GDS, I work on GOV.UK Pay, a platform that helps government services of any size take payments from members of the public. I write the documentation that developers in government services use to integrate with GOV.UK Pay's API.

  What is the story behind how you became a technical writer? What appealed to you most about technical writing as a career path?

  I studied English at university and sleepwalked into being an English teacher at GCSE and A-level. I taught for 5 years and, as amazing as the good days were, there were fewer and fewer good days as time passed. Teaching is hard!
