Cisco bug
To prevent Smarts IP from polling this OID you will need to edit the DISCOVERY_CISCO.import.When editing this file please use the sm_edit function. (ie <base>/bin/sm_edit -s<domain name> ..conf/discovery/DISCOVEY_CISCO.import GA_Driver::Performance-Cisco-Router-Driver {ReadsRulesFrom = GA_RuleSet::Performance-Cisco-Router-RS { fileName = "discovery/ic-cisco-router-health.asl" } ReadsInputFrom = SNMP_WalkFE::Performance-Cisco-Router-FE {rootOIDs = { cpmCPUTotal5minRev # CPU will be created using cpmCPUTotal5minRev by default { 5, ".1.3.6.1.4.1.9.9.109.1.1.1.1.8" } , cpmCPUTotal5minOID { 10, ".1.3.6.1.4.1.9.9.109.1.1.1.1.5"} , # CPU will be created using cpmCPUTotal5min when there's no data for cpmCPUTotal5minRev avgBusy1 { 15, ".1.3.6.1.4.1.9.2.1.57" } , # CPU will be created using avgBusy1 when there's no data for cpmCPUTotal5minRev and cpmCPUTotal5min ciscoMemoryPoolName { 20, ".1.3.6.1.4.1.9.9.48.1.1.1.2" }, # freeMem { 25, ".1.3.6.1.4.1.9.2.1.8" }, Please comment out the line: { 20, ".1.3.6.1.4.1.9.9.48.1.1.1.2" } This change will require a restart of AMPM domain.
Please not that as this OID is a basic CPU OID smarts will poll this OID in an AM domain as well. Also please note that this will effect all Cisco Routers that use this OID. If you are concerned with this please contact Cisco to see if there is a resolution to the bug on their side. This article is simply a workaround until the bug can be resolved.
