vzstatrep Configuration File

The vzstatrep.conf configuration file located in the /etc directory on the Monitor Server is used by the vzstatrep utility while trying to generate statistic reports and graphics on the server resource consumption and to send them to your e-mail address. This file has a number of lines in the following format:

<parameter_name> =" parameter_value "

Below is a list of available parameters:

Name

Description

NODES

The IP address or hostname of the server whose logs are to be analyzed. You can set several servers for being processed with the help of the vzstatrep utility and separate them by spaces. If no server is specified, the logs of the local server (i.e. of the Monitor Server itself) are analyzed.

STATS_EMAIL

The e-mail address to send the generated statistic reports and graphics to. You can specify several e-mail addresses and separate them by commas or spaces.

GNUPLOT

The path to the gnuplot utility on the Monitor Server. By default, the utility is located in the /usr/bin directory; however, you may specify another directory for its location (e.g. /etc/mydir/gnuplot ). gnuplot is used by the vzstatrep utility to present the server resources consumption in the graphical form. The resources whose graphics are to be generated should be set as the values of the STATS_PLOT parameter. For detailed information on the gnuplot utility, see its man pages.

MUTT

The path to the mutt utility on the Monitor Server. By default, the utility is located in the /usr/bin directory; however, you may specify another directory for its location (e.g. /etc/mydir/mutt ). mutt is used by the vzstatrep utility to send the generated statistic reports and graphics in the form of attached files via e-mail. For detailed information on the mutt utility, see its man pages.

LOGS_DIR

The path to the directory on the server where vzstatrep will search for the logs generated by the vzlmond daemon and containing the information on the server resources consumption. By default, the /var/log/vzstat directory is used. If you have changed the directory where vzlmond stores the gathered information, you should specify the full path to this directory as the value of this parameter (e.g. LOGS_DIR=/my_logs/vzstat ).

STATS_PLOT

Specify the resources parameters whose graphics are to be generated by means of the gnuplot utility. You can specify several resources and separate them by spaces. Currently, you can create graphics for the following parameters:

  • ve_sum : the information on the CPU usage for all Containers on the server.
  • ve_top : the information on the CPU usage for 5 Containers with the highest CPU consumption.
  • loadavg : the average number of active processes for the past 1, 5, and 15 minutes. Active processes can be running, i.e. currently executed by the CPU, or runnable, i.e. waiting in the run queue for the CPU.
  • io : the amount of data read from and written to all devices on the server, in kilobytes per second.
  • mem : the total memory consumption on the server.
  • ints : the number of interrupts and context switches on the server per second.
  • cpu : the information on the CPU load on the server.
  • net : the network information for each network interface on the server.
  • forks : the number of copies of all processes made on the server during one second.

By default, all the aforementioned resources except for ve_sum are plotted.

To start analyzing the logs, creating the server statistic reports and graphics, and receiving e-mail messages with these reports and graphics, you should specify the NODES and STATS_EMAIL parameters in the /etc/vzstatrep.conf file. All the other parameters are automatically set during the vzrmon package installation on the Monitor Server.
