NTP servers used do not match across cluster members-juniper-junos
Vendor: juniper
OS: junos
Description:
Indeni will identify when two devices are part of a cluster and alert if the NTP servers they are using are different.
Remediation Steps:
Review the NTP configuration on each device to ensure they match.

ntp-servers:
why: |
This metric shows if at least a NTP server is configured. NTP servers are used to sync the time across all hosts and network devices.
This is critical for things such as event correlation and logging. Use Network Time Protocol (NTP) to set the date and time if possible.
However, it is important to ensure the NTP UDP port is allowed through the firewalls on your network.

This script logs into the Juniper JUNOS-based device using SSH and retrieves the output of the "show ntp associations" command.

ntp-server-state:
why: |
Even though NTP servers are configured, that does not guarantee that they work. It is important to track the actual state of the NTP server.
Properly sync'd NTP servers are critical for things such as event correlation and logging. In addition, clock drift can lead to authentication failures and connectivity issues.
