From Nagios to TrueSight with Monitoring Studio

Nagios is a popular open-source monitoring solution which is often implemented by default to monitor non-critical parts of the IT in many organizations. It’s simple, free, and has a rich set of plugins.

 

IT professionals might wonder then why they should migrate from Nagios to TrueSight. The answer is simple and obvious, Nagios has too many limitations:

 

Wrong-24.png Painful configuration

Wrong-24.png Ungainly interface

Wrong-24.png No auto-baselining, no root cause analysis, no correlation, no application mapping

Wrong-24.png Only monitors non-critical areas of IT

 

To put it simply, Nagios lacks many of the essential features of modern monitoring solutions.

Until now, migrating from Nagios to TrueSight was a time-consuming, costly, and painful project that many organizations avoided because of the costs involved. Migrating from Nagios to TrueSight used to mean:

With version 9.2 of Monitoring Studio, the migration from Nagios to BMC TrueSight Operations Management is now child's play and a matter of minutes.

 

A SIMPLE MIGRATION PROCEDURE

With Monitoring Studio 9.2.00, every effort has been made to make admins’ life easier by providing them with a convenient and intuitive migration interface. The migration procedure is extremely simple and can be summarized in three points only:1Install_2Import_3Cleanup.png

  1. First, IT admins install the PATROL Agent and the latest Monitoring Studio package on their Nagios server itself.
  2. Then, they import their Nagios configuration using a user-friendly wizard that will translate their Nagios configuration into a TrueSight configuration. They just need to specify the credentials required to connect to the monitored systems.
  3. And finally, they can stop their Nagios server, and NRPE agents as they are no longer needed.

 

And that’s it! Monitoring Studio will start using the Nagios plugins natively.

 

 

BEFORE, DURING, AND AFTER THE MIGRATION

 

archdiagram1.pngAs explained previously, administrators using Nagios do not need to worry about the migration process as the latter is totally handled by Monitoring Studio itself. It is nonetheless interesting to see more in details the changes made in their IT environment.

 

First, before the migration, BMC and Nagios environments are separated and work independently: the already existing Nagios environment on one side, and the recently set BMC TrueSight Operations Management environment on the other.

CONCLUSION

Administrators who have chosen simplicity by opting by default for Nagios, rapidly end up hampered by its lack of essential features, and hindered from doing what they really want. They wish to evolve and go further with the monitoring of their various technologies and migrating turns out to be the only solution.

For these admins, Sentry Software has developed Monitoring Studio: the perfect tool for a complete and smooth transition to BMC TrueSight Operations Management, a full agent-less monitoring solution with valuable and powerful features to fully meet any admins’ custom monitoring needs and go beyond.
