Hi, Currently there is ping mechanism in DMQ for detecting inactive nodes. However this triggers only on "ping_interval".
DMQ exposes API functions to other modules for sending dmq messages or broadcasting them. This API functions require "dmq_resp_cback_t" to be passed as parameter. Most of the other modules just log a DBG msg in it. There are two improvement ideas: 1. other modules that use DMQ, to detect node failures too, as they are sending/bcasting messages. This, in addition to DMQ module "ping_interval" mechanism. 2. don't set inactive state of nodes on first failure, but have per node counter of fails, and modparam to tune this check. To do this either: A. Implement the response callback in each module that use DMQ, to check response code and set inactive state of dmq node => duplicate same code across different modules B. Send NULL for that "dmq_resp_cback_t" from other modules that use DMQ. In DMQ module itself, check if NULL and if so, use a default callback that checks response code and set inactive state of dmq nodes => cleaner approach Any opinions on this? Do you see any possible problems with this? Thanks, Stefan
