* Description:
|
||||
*
|
||||
*
|
||||
* This file contains the check_ntp_peer plugin
|
||||
*
|
||||
* This plugin checks an NTP server independent of any commandline
|
||||
* programs or external libraries.
|
||||
*
|
||||
* Use this plugin to check the health of an NTP server. It supports
|
||||
* checking the offset with the sync peer, the jitter and stratum. This
|
||||
* plugin will not check the clock offset between the local host and NTP
|
||||
* server; please use check_ntp_time for that purpose.
