Monitor Tab doesn't show invocations for Non-HTTP Triggered Functions on the Linux Consumption Plan

#### Investigative information

Please provide the following:

- Timestamp:2019-07-01T10:49:00.0356745Z
- Function App version (1.0 or 2.0): 2.0 (2.0.12490)
- Function App name: TimerTriggers
- Function name(s) (as appropriate):
- Invocation ID:78e4b797-f4ce-497d-a0b7-8a8eef460ac6
- Region:West Europe

#### Repro steps

Provide the steps required to reproduce the problem:

1. Create a new Python Function App
2. Add a new Timer Triggered Function schedule":"0 */1 * * * *"
3. Deploy to Linux Consumption Plan.
4. Add Application Insights
5. Wait an hour.
6. Run the Function once in the Portal.
7. Visit the monitor tab.

#### Expected behavior

Provide a description of the expected behavior.

After Step 6 there should be at least 60 invocations of the Function TimerTrigger.
There will be only one from the Portal invocation.


#### Actual behavior

Provide a description of the actual behavior observed.

1. The Monitor tab is querying the Requests table.

{
"query": "requests | project timestamp, id, operation_Name, success, resultCode, duration, operation_Id, cloud_RoleName, invocationId=customDimensions['InvocationId'] | where timestamp > ago(30d) | where cloud_RoleName =~ 'testfinpyfunction' and operation_Name == 'TimerTrigger' | order by timestamp desc | take 20"
}

2. The Invocations are recorded in the Traces table.

traces | where timestamp > ago(30d) | order by timestamp desc | take 10

#### Known workarounds

Provide a description of any known workarounds.

No workarounds exist.

1) Sampling has been disabled for Application Insights.
2) Placeholders have been disabled.
