Update for: m25, m35, m50, m70, r45, r90, r1000, and v35

Release notes for Enterprise Monitoring Point version 12.4.0.

Enhancements

  • 802.1X support added—We have added support for 802.1X authentication. This feature provides port-based layer-2 access control to authenticate monitoring points for access to a secured LAN or WAN. With this update, AppNeta monitoring points can now be authenticated on networks that employ 802.1X authentication.
  • Configure DNS nameservers per address—We have updated the Admin API to allow DNS nameservers to be configured for each address on an interface. Previously, nameservers could only be configured at the interface level. The new endpoints include GET, POST, and DELETE /interface/<interface_name>/<address>/dns_nameserver/. The existing endpoints (GET, POST, and DELETE /interface/<interface_name>/dns_nameserver/) now apply only to a dynamically configured address (i.e. DHCP, DHCP6, SLAAC) or, if only static addresses are configured, the first static address specified. Note that for DHCP interfaces, the existing GET endpoint returns the configured DNS nameservers as well as any provided by DHCP servers.
  • Configure DNS Search Domains per address—We have updated the Admin API to allow DNS Search Domains to be configured for each address on an interface. Previously, Search Domains could only be configured at the interface level. The new endpoints include GET, POST, and DELETE /interface/<interface_name>/<address>/dns_search/. The existing endpoints (GET, POST, and DELETE /interface/<interface_name>/dns_search/) now apply only to a dynamically configured address (i.e. DHCP, DHCP6, SLAAC) or, if only static addresses are configured, the first static address specified. Note that for DHCP interfaces, the existing GET endpoint returns the configured Search Domains as well as any provided by DHCP servers.
  • Experience Google Chrome 75—Experience monitoring now uses Google Chrome 75 to interact with the web applications that you target. Upgrading Chrome ensures that AppNeta monitoring points stay up to date with performance and security improvements. In addition, the upgrade improves the resilience of some workflow scripts, and makes them even more representative of real end user experience. As with any Chrome upgrade, you may notice changes in the execution time of your Experience web path workflows – faster or slower – and the way time is attributed to network, server, or browser. In some cases, you may also see different or additional javascript errors. A purple diamond indicator will be placed under the End-User Experience and Milestone Breakdown charts on the Test Timeline page when Chrome is upgraded, so you will quickly be able to see whether it has had an affect on script execution.

Resolved issues

ID Keyword Description
MP-1804 Experience We fixed an issue where Experience monitoring could show 100% load along with unexpected gaps in Usage monitoring data.
APM-4022 PathTest We fixed an issue where TCP PathTest could show incorrect capacity measurements.
APM-3680 Routing We fixed an issue where the expected routing for UDP traceroutes was not being followed.
MP-1823 Overload We fixed an issue where, when the monitoring point was overloaded, data was collected at much longer intervals than expected.
MP-1826 Offline We fixed an issue where a monitoring point could go offline and require a reboot to bring it back up.
APM-3976 Connectivity We fixed an issue where multiple paths could get into a “Connectivity loss to target” state even though the targets could be pinged.
MP-1794 Error message We fixed an issue where an error message indicated an issue with an interface when the actual problem was that a host could not be resolved via DNS.
MP-1584 QoS change We fixed an issue where a network path showed a QoS change violation but diagnostics did not report the change.
MP-59 Capacity measurement We fixed an issue where a total capacity measurement could be shown exceeding the link capacity and skewing the provisioned capacity.

Changes to be aware of

Updated operating system—The release includes an updated Debian operating system (9.8->9.9) and an updated kernel (4.19.57->4.19.68). These updates address several security issues.
