Application insight not showing data of all function apps

Harendra Prasad 1 Reputation point

We have 14 function apps with a single app service plan (S2). And all function apps configured with single application insights. Initially, application insights were showing data for all function apps now it is showing only for one function apps.
I checked all configurations like APPINSIGHTS_INSTRUMENTATIONKEY in function apps configurations. All is looking fine.
When I go to the performance section and select roles then it shows only one function app name instead of all 14 apps
