NAME¶

pcp-uptime - tell how long the system has been running

DESCRIPTION¶

pcp-uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes.

When invoked via the pcp(1) command, the -h/--host, -a/--archive, -O/--origin, -Z/--timezone and several other pcp options become indirectly available.

OPTIONS¶

The available command line options are:

-V, --version

Display version number and exit.

-?, --help

Display usage message and exit.

NOTES¶

pcp-uptime is inspired by the uptime(1) command and aims to be command line and output compatible with it.

PCP ENVIRONMENT¶

Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).

For environment variables affecting PCP tools, see pmGetOptions(3).
