The Net-SNMP support for such monitoring uses the DisMan Event MIB, which works on a "trigger/reset" model. It's not designed to send repeated traps for a single condition. > I would like to change this to have it send [the low disk space trap] every > hour until the issue clears. I'm guessing this would require using the > 'repeat' directive to reset the error flag periodically, but am unsure. That's not really how the Event MIB (or "monitor" directive) works. The simplest approach would actually be to code this yourself, using the example/notification module as a template. Register a repeating alarm to call a routine that would retrieve the value(s) you are interested in (using 'netsnmp_query_get()' or 'netsnmp_query_walk()'), check the values against the relevant threshold(s), and invoke a version of 'send_example_notification()' if appropriate.
