Background

This ZenPack checks the health of an NTP server and monitors the offset with the sync peer. The ZenPack uses the pre-installed Nagios plugin "check_ntp_peer" to perform this task.

Usage

The NTPMonitor template must be bound to the device class or device you want to monitor.

  1. Select Infrastructure from the navigation bar.
  2. Click the device name in the device list.
  3. Expand Monitoring Templates, and then select Device from the left panel.
  4. Select Bind Templates from the Action menu.appears.
  5. Add the NTPMonitor template to the list of selected templates, and then click Submit.

The NTPMonitor template is added to the list of monitoring templates.

Tips

  1. If Error = "NTP CRITICAL: No response from NTP server"; verify if server is a NTP server
  2. If Error = "CRITICAL - Socket timeout after 10 seconds"; check device restrictions in ntp configuration file (/etc/ntp.conf for Linux) for "noquery".
  3. If Error = "NTP CRITICAL: Server not synchronized, Offset unknown"; synchronize NTP server with NTP.
