What format is the nmon output file?

0

Plain ASCII text that you can edit and editable with vi (but you might hit the 2048 byte line limit on the AIX vi). I use the Open Source vim on AIX to avoid this or do it on Linux. • The first token on the line tells you what sort of data it is • AAA lines are basic nmon data about this collection of data • BBB lines are about the configuration of the machine • ZZZ lines include the date and time stamp stored here once ro reduce output • others should be obvious • the second field is the Timestamp – see the ZZZ section to the actual time • then there is the data • each sort of data (CPU, DISK, etc.) has a Header line that describes the columns and the header lines also include the graph titles You do not need to sort the nmon output file for nmon2rrd or the Analyser but it you do then you can see the sections easier for editing.
