Hi list. We are implementing a system in wich we have a "Monitor" and a "Monitoring Central". Certain events in the monitor generate an alarm which is sent to the monitoring central in a snmp notification. We would like to be sure that every alarm generated on the monitor arrives one and only one time to the monitoring central.
I've read the man pages, the wiki and google, but i have not found answers for the following points. Can anyone know where can I search, or has the answer for some of this questions? - First of all, can snmp notifications be sent over TCP instead of UDP? - snmpinform talks with snmpd in order to deliver the notification. I've seen that snmpd has a buffer of commands to process. Does snmpinform exit after passing the notification to snmpd (even if snmpd hasn't processed it yet)? I think not, but want to be sure. - If not, wich are the exit codes of snmpinform (snmpcmd?) I mean, I saw that snmpinform can be used in such a way that it retries the inform-request n times, with x seconds between each retry. But how can I differentiate the case in wich the program exits because it receives the confirmation from the manager, from that in which the program exits because it has reached the maximum number of retries? This is about being sure that the "alarm" arrived to the monitoring central. In order to manage repeated "alarms" (because of lost confirmations), - Does snmptrapd recognize a repeated snmp notification (because it's previous confirmation was lost)? - If yes, is there a way to identify a notification as being the same, even between different invocations of snmpinform? If mean, if I do not instruct snmpinform to retry, there is no confirmation, and the monitor retries the invocation of the snmpinform to send "the same alarm" (I think not, and this should be managed in the monitoring central). Well, thanks in advance. I hope I explained myself. Antonio ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
