Previously, sending Watcher alerts to email required editing configuration files in the command line and restarting the Elasticsearch container. An update to the Watcher alerts feature creates a simpler configuration method using the Analytics Node UI and supports sending Watcher alerts to remote Syslog servers.

The DANZ Monitoring Fabric (DMF) Application Identification feature allows monitoring of applications identified from packets taken from filter interfaces and sent through the fabric by sending IPFIX reports to a collector. The feature provides a filtering function by forwarding or dropping packets from specific applications before sending the packet to the analysis tools.

In DANZ Monitoring Fabric (DMF) 8.6, the Controller supports modular chassis switches. A chassis can have one or more line cards. On the Controller side, a chassis switch with multiple line cards, each with its own ASIC, will be treated as a single switch. When connected, the chassis should work like any regular switch and requires no user intervention for this support to work. The Controller will automatically pick up the chassis, initiate a handshake, and react to any chassis events like line cards added or removed.

In a typical CloudVision-DMF integration deployment, CloudVision Portal (CVP) deploys alongside the DANZ Monitoring Fabric (DMF). The DMF Controller communicates with CVP to retrieve its managed device inventory and configures port mirroring sessions on any CVP-managed production devices that are Arista Extensible Operating System (EOS) switches.

Latency and drop information help determine if there is a loss in a particular flow and where the loss occurred. A Service Node action configured as a DANZ Monitoring Fabric (DMF) managed service has multiple separate taps or spans in the production network and can measure the latency of a flow traversing through any pair of these points. It can also detect packet drops between any two points in the network if the packet only appears on one point within a specified time frame, currently set to 100ms.

DANZ Monitoring Fabric (DMF) vCenter integration supports mirroring from vCenter hosts using the default TCP/IP stack. However, this can result in traffic drops and affect production traffic since mirror traffic can conflict with production traffic. DMF vCenter integration with Mirror Stack provides the functionality to use the mirror TCP/IP stack for mirror sessions. Mirror stack in the ESXi host allows decoupling the traffic and keeps the production traffic unaffected.

When some LAG member links go down, it may be preferable to isolate the filter switch by bringing down the entire LAG interface rather than delivering unreliable data to tools and devices. Two new commands are now part of the DANZ Monitoring Fabric (DMF) lag-interface configuration to aid in managing the LAG interface when a specified number of links go down.

For an active/standby cluster configuration, the user can reload or reboot the node. When the active node is reloaded or rebooted, the standby node becomes the new active node. When the user logs in to the Virtual IP of an active/standby cluster configuration, the user can reload or reboot the active node. The Virtual IP (VIP) logs in to the new active node without the user changing IP addresses. The new standby node will not have the reload or reboot functionality unless that node is directly logged into by the user.

As a result of upgrading the Debian distribution to Bookworm, the original Python CLI (based on python2) was removed, as the interaction with the DANZ Monitoring Fabric (DMF) and CCF is performed mainly from the Controller. However, several customer operations involve some of the commands used on the switch. These commands are implemented in the new CLI (based on python3) in Switchlight in the Bookworm Debian distribution.
