    • Node Agent

    Description

      There is a certain set of information that we simply cannot access without running code directly on the Couchbase Server hosts - for example THP configuration (kernel parameter), or whether there are firewalls between the CBS nodes (need to try establishing TCP connections, ergo, need node-level access).

      This is a long-term tracking CMOS for all the work needed to make checks like that possible. The exact implementation is up for discussion - in the long term ideally it'd be embedded within CBS (either ns_server or as a babysitter managed agent), but for the time being we're interested in the lowest friction solutions for incremental adoption.
