What are the main components of the Metric Insights stack?

The main components of the Metric Insights stack are listed below. Versions listed are the minimum required.


* Metric Insights is not compatible with PHP7 and Python3 currently. We plan on migrating to both in a future 6.x release in 2019.

* For system and base linux package requirements, please see the following articles:

Versions 5.0+ (latest release 5.4.0):

  • [Linux] CentOS 6/7, RHEL 6/7, Debian 7/8
  • Apache 2.2
  • MySQL Server 5.5+ (Configured to only accept local connections)
  • PHP 5.6
  • Python 2.7
  • Java 7  
  • Kernel 3.10+

Versions pre 4.2

Notes on SSL/SSH

Encryption to and from the MI virtual appliance (if using an MI provided OVA image) makes use of OpenSSL version 1.0.2k (this version does not suffer from the Heartbleed vulnerability).  SSH Communication with the server uses OpenSSH 7.4p1.
