Host logging for EOL or soon-to-be EOL PowerShell Apps #11239
Description
What problem would the feature you're requesting solve? Please describe.
Show regular warnings when an EOL or soon-to-be EOL version is detected for a PowerShell app. This warning should be visible and accessible through App Insights.
Describe the solution you'd like
| Action | Condition | Behavior | Warning message. |
|---|---|---|---|
| Upon app start/load | Functions version and/or stack version is out of support | Show warning message. | "Upgrade to Functions/Stack version as <stack/functions runtime version> has reached end-of-life on and is no longer supported. Learn more: aka.ms/FunctionsStackUpgrade" |
| Regular cadence (24h?) | Functions version and/or stack version will be out of support in less than 6 months | Show warning message. | "Use Functions/Stack version as <stack/functions runtime version> will reach end-of-life on and will no longer be supported. Learn more: aka.ms/FunctionsStackUpgrade" |
Describe alternatives you've considered
Warnings already exist for such apps in the portal and client tools, but host logging is critical for customer awareness.
Additional context
Current Behavior:
No warning/error is written by Host for EOL apps, and hence these logs are not available on AppInsights.
Acceptance Criteria:
Work item can be marked 'Completed' when we have implemented, tested and deployed the logic to show the above mentioned warning message when an app loads, and at a regular cadence thereafter when a Function App is configured with a stack runtime version that has a) reached its end-of-life date, or b) will reach its end-of-life date in <6months.
Additional information:
- Getting current stack version information: See this
For Linux:
All stacks - get app runtime version from linux_fx_version (from site config)
For Windows:
Node: WEBSITE_NODE_DEFAULT_VERSION (from app setting)
.NET: netFrameworkVersion (from site config)
Java: javaVersion (from site config)
PowerShell: powerShellVersion (from site config)
- Compare against EOL dates in StacksAPI: See this
