sar package

Under Ubuntu the sar command is part of the sysstat package. Do not confuse this with atsar, which is obsolete and unmaintained.

After sysstat in installed be sure to enable data collection by editing /etc/default/sysstat and setting ENABLED="true".

Requested activities not available in file

This happens most often when sysstat was not configured to record the given data. For example, `sar -b` or `sar -d`. You must edit /etc/cron.d/sysstat and add the option to store the given dataset.
