If you have a Cisco router with a lot of routes, doing an snmpget on the routing table, which Zenoss does, will bring it to it's knees. Has to do with the way routes are stored in the routing table and the need to reorder them for every route when an snmpget is done against the routing table. Create a 'view' that excludes the routing table. See the following links for details; http://www.netcraftsmen.net/welcher/papers/snmprouter.html http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094489.shtml -------------------- m2f -------------------- Read this topic online here: http://forums.zenoss.com/viewtopic.php?p=27561#27561 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
