We are currently running into a problem in our Linux App Service resources.

The first thing that we have noticed is that for a brand new, near empty WebAPI deployment – into a fresh WebApp, App Service and Resource group – we have an immediate temp storage usage of +/- 22GB. When we compare this with Windows App Services (+/- 200MB) this seems excessive. Is this normal, or do we have an anomaly?

    Hi @Lukasz Andrzejak we ended up working together with Microsoft/Azure Support in identifying what caused the temp files with us to fill up. In the end for us it was the ApplicationInsights profiler which a developer added and forgot to remove when debugging a problem in the past. This caused the temp folder to fill up with dumps etc. We also tuned our app service plans better so they have a little bit more breathing room.

    Hi @Jamie Greeve ,

    I've been able to confirm that the high temp file usage is expected on Linux app service plans. It contains the blessed docker images of the various supported runtimes.

    The Linux - Host Disk Space Usage elaborates on this a bit further and provides insights on what to do should your usage increase.

    Regards,
    Ryan
