[ceph-users] Permanently ignore some warning classes

Dear Ceph users, my cluster is build with old hardware on a gigabit network, so I often experience warnings like OSD_SLOW_PING_TIME_BACK. These in turn triggers alert mails too often, forcing me to disable alerts which is not sustainable. So my question is: is it possible to tell Ceph to ignore (or at least to not send alerts for) a given class of warnings? Thank you, Nicola
