|
||
<div class="sreweekly-description">
|
||
<p>VictorOps held a webinar last Thursday to present and discuss the concept of context in incident management. Just paging in a responder isn’t enough: we need to get them up to speed on the incident as soon as possible. Ideally, the page itself would include snapshots of relevant graphs, links to playbooks, etc. But if we’re not careful and add too much information, the responder is overloaded by a “sandstorm” of irrelevant data. “time to learn” — post incident learning careful of info overload in presenting context with pages</p>
|
||
<p><small><em>This webinar was created by my sponsor, VictorOps, but their sponsorship did not influence its inclusion in this issue.</em></small></p>

<p>Here’s the next in Stephen Thorne’s series of commentary on chapters of the SRE book. I like that Google makes an effort not to be <em>too</em> reliable for fear of setting expectations too high, and they’re also realistic in their availability goals: no end-user will notice a 20-second outage.</p>

<p>I love that the ideas we’re talking about regarding human error apply even to commercial cannabis growing.</p>
