Cluster down-juniper-junos
Vendor: juniper
OS: junos
Description:
Indeni will alert if a cluster is down or any of the members are inoperable.
Remediation Steps:
Review the cause for one or more members being down or inoperable.
How does this work?
This script logs into the Juniper JUNOS-based device using SSH and retrieves the output of the “show chassis cluster status” command. The output includes the status of all redundancy groups across the cluster.
Why is this important?
Tracking the state of a cluster is important. If a cluster which used to be healthy no longer is, it may be the result of an issue. In some cases, it is due to maintenance work (and so was anticipated), but in others it may be due to a failure in the members of the cluster or another component in the network.
Without Indeni how would you find this?
The administrator has to run the “show chassis cluster status” on the device to find whether neither of cluster nodes is in primary state.

Tracking the state of a cluster member is important. If a cluster member which used to be the active member of the cluster no longer is, it may be the result of an issue. In some cases, it is due to maintenance work (and so was anticipated), but in others it may be due to a failure in the firewall or another component in the network.

cluster-preemption-enabled:
why: |
Preemption is a function in clustering which sets a primary member of the cluster to always strive to be the active member. The trouble with this is that if the active member that is set with preemption on has a critical failure and reboots, the cluster will fail over to the secondary and then immediately fail over back to the primary when it completes the reboot. This can result in another crash and the process would happen again and again in a loop.
