The ACD Router requires a minimum CPU architecture level of x86-64-v2 due to inclusion of Oracle Linux 9 inside the container. While all modern CPUs support this archetecture level, virtual hypervisors may default to a CPU type that has more compatibility with older processors. If this minimum CPU architecture level is not attained the containers may refuse to start. See Operating System Compatibility and Building Red Hat Enterprise Linux 9 for the x86-64-v2 Microarchitecture Level for more information.

When configured to use TLS, acd-telegraf-metrics-database might log the following error message: http: TLS handshake error from <client ip>: client sent an HTTP request to an HTTPS server when receiving metrics from caches even though the Telegraf agents are configured to use TLS. The Telegraf logs on the caches do not show any errors related to this. However, the data is still received over TLS and stored correctly by acd-telegraf-metrics-database. The issue seemingly resolved itself during investigation and is not reproducible. Current hypothesis is a logging bug in Telegraf.
The Telegraf metrics agent might not be able to read all relevant network interface data on ESB2001 releases older than 3.6.2. The predictive load balancing function host_has_bw() and the health check function interfaces_online() might therefore not work as expected.
- The recommended workaround for host_has_bw() is to use host_has_bw_custom(), documented in Built-in Lua functions. host_has_bw_custom() accepts a numeric argument for the host’s network interface capacity which can be used if the data supplied by the Telegraf metrics agents do not contain this information.
- It is not recommended to use interfaces_online() for ESB2001 instances until they are updated to 3.6.2 or later.
