Azure app services have a lot of very cool features and abstract many of the responsibilities more traditional Virtual Machines would bestow upon it's owners. However, one of the things you still have to concern yourself with is the disk spaced used by your application. Normally an application in Sitecore is not going to be that huge since we're not counting any of those OS level files and directories and most of your media assets are going to be put into blob storage or a CDN somewhere else. However, if you run your App Service for long enough you may eventually see the storage space usage increase to a point where it becomes dangerous. Similar to how a Memory leak grabs your memory resources without letting them go and balloons, in this case we're talking about a Filesystem leak. SYMPTOMS: - App Service backups begin to fail - You notice the disk space usage of your app services continually growing past what you'd expect normally - You experience "System.IOEx...
So you've gone through the process of building a brand new Sitecore environment totally pristine. You've installed your favorite APM (Application Performance Monitor) tool and made sure it's working. You're about ready to let your development team rip into this work of digital craftsmanship when you notice it; a flood of exceptions across multiple application services all seemingly tied together. SYMPTOMS: - Clean environment without any custom configs/code - Exception being reported every 5 minutes, almost like clockwork - The same 403.14 error appears across all of the xConnect Services (xConnect Collection, xConnect Search, xConnect Reference Data, Marketing Automation Operations, Marketing Automation Reporting, Cortex Processing, Cortex Reporting). - 100% - 50% error rate reported by the APM (New Relic in my case) - No Sitecore errors capture in Application Insights THE BREAKDOWN: Relax, take a moment to breath in ... then breath out, everything will be OK.
