For those of a certain age group, or for those with a sense of history, you may have been aware of the NonStop Open System Interconnection / Message Handling System (OSI/MHS) subsystem.

Insider Technologies developed “ActionView.400”, the OSI/MHS X.400 monitoring product which was shipped with the older Tandem/HPE NonStop platforms and since December 2018, has been marked by HPE, as obsolete.

However, we support customers in the Government and Military sectors where the monitoring and tracking of X.400 and SMTP/MIME emails is essential to ensure that SLAs are met and every message can be accounted for – for the military especially, a pretty critical requirement one would think?

Insider also has customers in message tracking arenas for BASE24, XML, MQ, including solutions for “WayPoint”, aka Store-and-Forward mechanisms (SAF), BAM, JMX, again, across multiple platform and vendor environments – all monitored via a single Sentra interface.

A description of two types of our message tracking solutions follows but to start with…


Sentra Architecture

Architectural design for monitoring and tracking email/MTAs across multiple platforms and MTAs.

1) X.400/SMTP Message Tracking

The manual monitoring of these types of protocols requires highly skilled engineers who understand the infrastructure and flow of the messages amongst large-scale global networks.

To assist with their monitoring requirements, our multi-vendor and multi-platform enterprise monitoring solution – Sentra – provides them with an invaluable addition to their toolset.

Note: Sentra does not interrogate the message content; it is purely concerned with tracking the delivery of messages through their global mail delivery systems.

Sentra Hypervisor for MTA

Top-level example for an MTA infrastructure based at Insider.

Drill-downs available to show message flows per platform and per SMTP/MTA agent. This is an extremely simple example compared to our Government and Military configurations.

Graphical Message Tracking

Graphical message tracking results allow you to see clearly, what happened to any given message without having to look inside it. In the example below, you can view the path the message has taken and obtain individual diagnostics.

2) WayPoint (SAF) Message Tracking

Payments, messages can be sent across multiple platforms.

Each message contains a particular id that is stored within Sentra, where its inbuilt correlation engine will track the required journey.

A series of XML agents are deployed to key monitoring points (WayPoints) within a payment / messaging processing infrastructure to monitor the message flows and calculate transaction volumes and trends, payment volumes and trends and end-to-end processing times.

Based on the Sentra stored data, rules can be configured to monitor service level compliance and abnormal processing volumes. Trend charts, alerts, queries can be created via the Sentra browser interface.

Note: A single Sentra installation provides this fully encompassed monitoring and tracking solution.


Without Sentra WayPoint Tracking

 Messages stored on each platform, with no waypoint tracking to determine for example, where the message is; if it is meeting its SLA delivery time; if there is any corruption.

I trust this article will illuminate you as to how we at Insider Technologies are pretty creative in providing in-depth tracking solutions for all types of messages, across any vendor and any platform; not just on HPE NonStop.
