When will nmon collect data from lots of machines or LPARs?
Never. I like to think nmon does one job and does it well – it collects data from one machine and saves it in one file. Going multiple machine or LPAR has many problems: • Collecting data from lots of machines or LPARs would require network access and lots of error handling for missing or late data. • The nmon output file would then be far more complex and have to include the machine names and totally rewrite the time stamps. • We already suffer from too much data than Excel can handle. • There would simply be too much data to display • This complication would mean nmon becomes very large and code stability would take a long time to settle down What you do need is: • Less data and then you drill down of particular nodes • Automated database generation to store the data • Automated graphing of the data you really want • History for the last hour, day, week, month year • Small simple daemons on the nodes and automated central collection point • Simple method of collecting more stats • Op
