Log Event

Nodinite enables End to End logging either from the use of any of the "out of the box ready to go" Log Agents or from your own solutions based on your own code. This enables you and Nodinite to use synchronous and asynchronous message exchange logging patterns.

graph LR subgraph "Log Monitoring Agent Configuration" roMessageBroker[fal:fa-bolt Nodinite Log Agents
BizTalk, Mule, Logic Apps, ...] roLogSink("fal:fa-bolt Custom Logging Solution") --> roId1["fal:fa-list Queue
fal:fa-folder Folder
..."] end subgraph "Web Server" roLogAPI(fal:fa-cloud-download LogAPI) roPS(fal:fa-truck-pickup Pickup Service)--> roLogAPI roId1 -.Log Event.-x roPS roLogSink --> |Log Event|roLogAPI roMessageBroker --> |Log Event| roLogAPI end

Architectural example with synchronous and asynchronous logging

We at Nodinite promote the use of asynchronous logging patterns

What is a Log Event?

A Log Event is an object represented as a JSON object and can be shipped either directly using the REST based Log API or you can send the very same JSON object to a persistent storage for Nodinite Pickup Service to fetch asynchronously. The latter means that:

  • Your logging solutions has no dependency on the Log API (reboot/update whenever you like)
    • You don't have to implement retries
  • You don't have to be lucky.... Running async is good for concurrency and the Pickup Service has limited number of threads and will not overload the Log API
  • ... this list can grow very large

Log Event (Mandatory) - Generic information about the event (like time, message type name and endpoint) - WHEN, HOW

  • Payload (Optional) - The business transaction with data, usually xml, json, flat file like EDI/X12 or zip file - WHAT
  • Context Properties (Optional) - Key value based collection of arbitrary data - (for example InvoiceId and CorrelationId) - WHAT
    • With the Context Options you can control the behaviour of how Nodinite processes events
graph TD subgraph "Event" subgraph "Details" roED[fal:fa-bolt Event Details
LogDateTime = 2018-05-03 13:37:00+02:00
EndPoint = https://api.nodinite.com/...
MessageType=Invoice
...] end subgraph "Payload" ro[fal:fa-envelope Message
base64EncodedMessage] end subgraph "Context Properties" roKey[fal:fa-key Key Values
InvoiceNo = 123
CorrelationId=456
...] end end

Architectural layout of a Log Event

Models

The Log API has the following entities defined:

How do I send Log Events using REST?

Follow the 'Log using REST' article to learn more.

How do I send Log Events using WCF?

Follow the 'Log using WCF' article to learn more.

Repository

Log Events can "auto populate" the Repository Model with special content. This will drastically reduce the amount of adminstration and the know how is transferred from developers to the business/IT Operations/AM-teams.

Note: You must enable the 'AllowRepositoryAutomapping' System Parameter for the Logging Service to honor the provided Repository Model related data
