If you are running Grid Control on HP-UX and you are using pseudo-swap, then you have to add the property:<\/p>\n
NMUPM_USE_PSEUDO_MEM=TRUE <\/p>\n
to the emd.properties. Otherwise, Swap Utilization is calculated wrongly (higher than acutal) and it might trigger false alarms.<\/p>\n
How is the Grid Control Agent calculating Swap Utilization?<\/p>\n
In file $AGENT_HOME\/sysman\/admin\/metadata\/host.xml line 310 you find some answers:<\/p>\n
\r\n\r\n<\/pre>\nIn other parts, you find the definition of “usedSwap” and “freeSwap”.<\/p>\n
\r\n \r\n \r\n<\/pre>\nNow, we have to find “usedSwapRaw” and “freeSwapRaw”. In a different part (line 387) of this file, you see this section:<\/p>\n
