SNMP Traps into MySQL is Sublime
+0 Vote Up -0Vote Down

I use snmptrapd to catch SNMP traps and then put them into a MySQL database using a pretty generic trap handler. This gives me the opportunity to generate such useful information as:

> SELECT HOUR(time) AS "hour", COUNT(*) AS "bounces" FROM snmptraps
    WHERE hostname = 'XXX' AND time > '2011-07-25'
        AND trap_oid = 'SNMPv2-MIB::snmpTrapOID.0 IF-MIB::linkDown'
    GROUP BY HOUR(time)
;
+------+---------+
| hour | bounces |

This tells us that interfaces on host 'XXX' where bouncing a lot until 10 AM and then stopped.
