Monitoring Functions in Azure

Don't let your business down! Monitor all your Azure Functions and gain access to details without the Azure portal.

Failed Functions
Non-Events (Too frequent, too few, too lengthy)
Managing Functions
Category Based Monitoring

On this page, you learn about Azure Function Monitoring options using Nodinite from one or more role-based Monitor Views. Nodinite monitors the Functions. You can manage the monitoring thresholds for the Function; Remote commands are available as Actions to help you swiftly address reported problems. The Remote Actions are detailed on the Managing Function page.

Example list of monitored Functions in a Nodinite Monitor View.

Monitoring Features

State Evaluation - Provide state evaluation according to pre-defined policy.

If Nodinite can't check the state of your Functions, chances are no one else can use them either.
Automatic Discovery of Function Apps and Functions.
- The Nodinite Azure Agent makes use of the Azure Rest API. Hence, Function Apps (Website) and Functions present automatically.
Category-based monitoring - Resources group by the Nodinite concept of Categories.
Share access to individual items from within Nodinite using one or more role-based Monitor Views.

State evaluation for Functions

The Functions to monitor manifests within Nodinite as one or more Resources. For example, if you have three Functions, you will have three Resources in Nodinite.

The Nodinite Resources name is the same as the deployed Function name.
Monitored Functions belong to 'Function' Category:

Many other Azure-related Categories exist as well, please review the Azure Logging and Monitoring Overview
The Application name is created with the following pattern: Configuration name/Resource Group Name

Each item (presented in Nodinite as a Resource) evaluates with a state (i.e. OK, Warning, Error, Unavailable).

You can override the evaluation process by configuring the Expected State option available for all Nodinite Resources.

Function

For Function Resources, the state evaluates as described in the table below:

State	Status	Description	Actions
Unavailable	Resource not available	Evaluation of the 'Function' is not possible either due to network or security-related problems	Review prerequisites
Error	Error threshold is breached	Non-Events Too few Too many Too lengthy State (Disabled)	Enable
Warning	Warning threshold is breached	Non-Events Too few Too many Too lengthy
OK	Within user-defined thresholds	State (Enabled)	Disable View history Details Edit Manage Keys Test

Function - Failed Executions

For Function - Failed Executions Resources, the state evaluates as described in the table below:

State	Status	Description	Actions
Unavailable	Resource not available	Evaluation of the 'Function - Failed Executions' is not possible either due to network or security-related problems	Review prerequisites
Error	Errors exist	At least one failed execution exists within the lookback period	List failed executions Clear all failed executions
OK	No failed executions	There are no failed executions within the lookback period

Function App Web Site

For Web Site - Function App Resources, the state evaluates as described in the table below:

State	Status	Description	Actions
Unavailable	Resource not available	Evaluation of the 'Function - Failed Executions' is not possible either due to network or security-related problems	Review prerequisites
Error	Errors exist	Function App (Website) is in the Stopped state	Start
OK	No problems exist	Function App (Website) is operational	Details Manage API Key Stop

Alert history for Function

During root cause analysis or for other purposes, it might be helpful to understand how often your Function problems occur. If your Monitor View allows it, you can search for historical state changes for the selected lookback period for all your Functions or individually. The generic instructions on the 'Add or manage Monitor View' page further detail this topic.

Search	Function history	Failed Function history	Web Site - Function App history
Search for alert history for all resources in the Monitor View	Alert history for the selected Function item	Alert history for the selected Failed Function item	Alert history for the selected 'Web Site - Function App' item
