uptime

uptime

Name

uptime -- Checks the uptime of the system.

Description

Uptime will report the amount of time that the system has been running. The information is displayed in the form "2 days, 4 hours, 7 minutes". Thresholds may also be set comparing against this amount, and graph data can be saved.

On Linux, the uptime is retrieved through the "/proc/uptime" file. This file is required in order for uptime to work properly.

On the Solaris OS, uptime is gathered using the "kstat" programming interface.

All Windows platforms use the Win32 API to gather information.

Configuration

Uptime requires no additional configuration.

Thresholds

Thresholds may be set for uptime by comparing the uptime against various time values. The units "days", "hours", "weeks", "minutes" and "seconds" may be used, separated by commas. So valid times would include "2 days", "2 hours, 5 minutes", or "3 seconds". Here is an example threshold:

# Example threshold for uptime
thresh1.threshold = Uptime.uptime > 1 day
		

History Data

The uptime module will save each uptime in seconds. This data, using the RSP History Viewer or RSP Web tools, can be used to create graphs of uptime.
