Monitoring Functions in Azure

Gain full control and visibility over your Azure Functions with Nodinite. This page explains how Nodinite monitors, analyzes, and helps you manage your Azure Functions, without the Azure Portal.

  • ✅ Instantly detect failed executions and abnormal patterns
  • ✅ Receive real-time alerts for too frequent, too few, or too lengthy executions
  • ✅ Manage Functions and thresholds remotely
  • ✅ Organize monitoring with category-based views for clarity

The Azure Monitoring Agent monitors these Categories:

Nodinite lets you monitor Azure Functions from one or more role-based Monitor Views. You set custom thresholds, receive alerts through Alarm Plugins, and use Remote Actions to resolve issues quickly. For details on the available Remote Actions, see Managing Function.

Diagram: The agent evaluates each Function, failed-execution, and Function App Resource into OK (green), Warning (yellow), or Error and Unavailable (red); Warning and Error raise alerts, and you resolve problems with Remote Actions.

Monitoring Features

  • State Evaluation – Nodinite evaluates the state of each Function based on your defined policies.

    If Nodinite can't check the state of your Functions, chances are no one else can use them either.

  • Non-Events Monitoring style checks – Detect too few, too many, or too lengthy executions within the lookback period.
  • Automatic Discovery – The Nodinite Azure Agent uses the Azure REST API to discover Function Apps and Functions automatically.
  • Category-Based Monitoring – Group Resources by the Nodinite concept of Categories.
  • Role-Based Access – Share access to individual items with Users through one or more Monitor Views.

State Evaluation for Functions

Nodinite presents each monitored Function as a Resource. For example, three Functions appear as three separate Resources in Nodinite.

Function-related Resources and Categories in a Monitor View
Example: Different types of Azure Function-related Monitoring Resources and Categories in a Nodinite Monitor View.

Each Resource evaluates to a state (OK, Warning, Error, Unavailable). The Monitoring Service collects the state from the agent. You can override the evaluation by configuring the Expected State for any Nodinite Resource.

Function

For Function Resources, the state evaluates as described below:

State Status Description Actions
🚫 Unavailable Resource not available
  • Evaluation of the 'Function' is not possible due to network or security issues
 Review prerequisites and Functions Monitoring requirements
❌ Error Error threshold breached ✅ Non-Events
  • Too few
  • Too many
  • Too lengthy
✅ State (Disabled)
⚠️ Warning Warning threshold breached ✅ Non-Events
  • Too few
  • Too many
  • Too lengthy
 Edit thresholds
✅ OK Within user-defined thresholds ✅ State (Enabled)

Set the thresholds with the Edit Remote Action, or globally in the agent Configuration.

Function Failed Executions

Nodinite evaluates the state of Function - Failed Executions Resources as follows:

State Status Description Actions
🚫 Unavailable Resource not available
  • Network or security issues prevent evaluation of 'Function - Failed Executions'
 Review prerequisites
❌ Error Errors exist At least one failed execution occurred within the lookback period
✅ OK No failed executions No failed executions occurred within the lookback period

Function App Web Site

For Web Site - Function App Resources, the state evaluates as follows (Web Apps without Functions: see Monitoring Web Site):

State Status Description Actions
🚫 Unavailable Resource not available
  • Evaluation of the 'Web Site - Function App' is not possible due to network or security issues
 Review prerequisites and the firewall settings
❌ Error Errors exist Function App (Website) is in the Stopped state
✅ OK No problems exist Function App (Website) is operational

The Function App Details include run statistics that help you set the Non-Events Monitoring thresholds; see Function App Web Site Details.

Alert History for Function

Nodinite makes it easy to analyze the frequency and patterns of Function issues. If your Monitor View allows, you can search for historical state changes for all or individual Functions over a selected period. See 'Add or manage Monitor View' for more details.
