Post mortem: we took 124 seconds from you, here\u2019s 378 back<\/a><\/div>\n
\n

A lighthearted but still detail-filled take on a post-incident analysis for a short production outage.<\/p>\n

Building Application Reliability on Top of Infrastructure Unreliability<\/a><\/div>\n
\n

This one has an interesting discussion of the nature of reliability and the impact of multiple services on overall reliability, including possible mathematical models to use.<\/p>\n

#30 Clearing Delusions in Observability (with David Caudill)<\/a><\/div>\n
\n

This episode of the SREPath Podcast covers a variety of themes around observability and SLOs. There\u2019s a great text-based summary if that\u2019s your preference.<\/p>\n

Linux Crisis Tools<\/a><\/div>\n
\n

This piece argues that you should install system debugging tools in on your production systems now, because it\u2019s going to be really hard to do it live when you need them.<\/p>\n

How much are their 9\u2019s worth?<\/a><\/div>\n
\n

Following on from a previous article<\/a> about the squiggliness of availability numbers, this article evaluates SLAs from 4 major companies to try to divine what they actually mean.<\/p>\n

SLO formulas implementation in PromQL step by step<\/a><\/div>\n
\n

I want to present real-life examples of both availability and latency SLOs, as they are more nuanced than they may initially appear. Also, I find it worthwhile sharing a detailed guide as it showcases uncommon uses of PromQL and demonstrates the language\u2019s versatility.<\/p>\n
