Known issues

These are the known issues affecting this release:

Issue key Description
MON-12663

A few customers have reported that their security solutions are flagging the package masscan-1.0.3-5.el7.x86_64.rpm as suspicious, hence preventing its download when updating OP5 Monitor.

In OP5 Monitor, Masscan is used by Nacoma for service discovery on hosts in the monitored network, by scanning and detecting open ports.

The full repository path to the package is http://repos.op5.com/epel/7/x86_64/Packages/m/masscan-1.0.3-5.el7.x86_64.rpm

Whitelisting the package should resolve the issue.

To download ITRS OP5 Monitor, including all components, see ITRS Downloads.

Highlights
