vzstat Configuration File

This file ( /etc/vzstat.conf ) lists a number of CPU-, memory-, and disk-related parameters used by the vzstat utility. The values assigned to these parameters denote either the warning or the error level for the vzstat utility to start displaying these parameters either in the yellow color (the warning level has been hit) or in the red color (the error level has been hit). Moreover, if a parameter has hit the error level, the CRIT warning is displayed instead of OK after the name of the corresponding subsystem (CPU, Memory, Swap, Net, or Disks).

The table below provides information on the name and the description of all these parameters, on whether they denote the warning or the error level, whether the real parameter value has to be higher or lower than this level in order to invoke an alert, and on the parameters default values:
