Update for: macOS NMP

Release notes for Enterprise Monitoring Point version 12.9.0.


  • Simplified macOS installation—We’ve enhanced the installer to make macOS Native Monitoring Point (NMP) installation easier for Work-From-Home users. Also, by default, the software is upgraded automatically as new versions become available.
  • Updated core capabilities on macOS NMP—We’ve updated the macOS NMP to include additional capabilities currently available on other Enterprise Monitoring Points. These include:
    • Route Visualizations of paths from a macOS NMP now show TCP and UDP traceroutes. Previously, they only showed ICMP traceroutes)
    • Ping and traceroute within PathPlus now support TCP and UDP. Previously, only ICMP was supported.
    • When creating network paths, you now have the ability to specify custom UDP port numbers for Continuous Path Monitoring (CPA) (previously, default source port numbers were used).
    • The return path for diagnostics on dual-ended paths can now be detected automatically or specified manually. This enables you to use non-default interfaces on the source and/or target for diagnostics testing.
  • Updated security protocol—To enhance security, TLS1.0 and TLS1.1 have been disabled. We now use TLS1.2 as the security protocol on the connection to AppNeta Performance Manager.
  • New menu bar app—The macOS NMP now includes a menu bar app that provides basic status and control functionality.

Resolved issues

ID Keyword Description
MP-3328 Manual restart required We fixed an issue where the Monitoring Point would occasionally stop and require a manual restart.
MP-3194 Failure to restart We fixed an issue where the Monitoring Point would fail to restart after a computer shutdown.
MP-3285 Security We have included fixes for a Monitoring Point vulnerability: CVE-2019-16275
MP-3284 Security We have included fixes for a Monitoring Point vulnerability: CVE-2020-15861

Known issues

  • Reboot may be required after upgrading from 8.4.x—We have noticed cases where, after upgrading the Monitoring Point, it still shows as version 8.4.x on the Manage Monitoring Points page in APM. In these cases, the computer running the macOS NMP needs to be rebooted.
  • High level of voice loss on certain ICMP paths—We have noticed significant voice loss on ICMP paths from v35s targeting the macOS NMP. This issue is currently being investigated.
  • Problems during rate-limited monitoring tests at high traffic rates—We have noticed macOS NMP failures when running rate-limited monitoring tests at the maximum testing rate (400 Mbps) that work fine at lower rates. We recommend using a maximum testing rate of 100 Mbps. This issue is currently being investigated.
  • Video test issues when macOS NMP is both a source and a target—When the macOS NMP is acting as both a source and a target during video tests, voice or video programs within the video test occasionally fail. This issue is currently being investigated.
  • Periodic jitter spikes cause packet discards in Voice/Video tests—The automatic time update on macOS causes periodic jitter spikes and results in packet discards during Voice/Video tests on the macOS NMP. To work around this issue, uncheck > ​System Preferences​ > Date & Time > Set date and time automatically.
  • macOS version support—Mojave, Catalina, and Big Sur are the only macOS versions currently supported. High Sierra and earlier versions are not supported. Also, Amazon Elastic Compute Cloud (EC2) Mac instances for macOS are not supported.
  • Issues targeting macOS NMP on Mojave—When a macOS NMP running on Mojave is a path target, dual-ended paths to it fail to connect. Paths where it is the source work fine.
