Linux Red Hat cluster discovery

  • Release version: Australia
  • Updated March 12, 2026
  • 1 minute to read

    • Discovery can find Linux Red Hat clusters that offer high availability and load balancing.

    Required credentials

    Configure SSH credentials.

    Additional requirements

    You also need permissions to read the /etc/hosts/ and /etc/cluster/cluster.conf file, which associates host names with IP addresses.

    The following commands are run for Oracle clusterware:
    Command

    ps -ef | grep corosync | grep -v grep

    clustat -x

    ifconfig | grep 'inet addr:' |awk '{print $1, $2 }'

    hostname -s

    hostname -s
    Sudo permission to run: sudo /u01/app/12.1.0.2/grid/bin/ocrcheck | egrep -v 'error|return code'

    Classifier, probes, and pattern

    Classifier Probes Pattern
    Linux

    (Unix classification)

    		 Horizontal discovery probe: launches patterns
    These patterns are an extension of the Linux Server pattern:
    • UNIX Cluster - Linux Red hat cluster
    • Linux - Red Hat Cluster

    The pattern uses the clustat -x command and looks at this cluster configuration file: /etc/cluster/cluster.conf
