1.4. Generating and collecting sos reports on multiple systems concurrently

Prerequisites

• You know the cluster type or list of nodes to run on.
• You have installed the sos package on all systems.
• You have ssh keys for the root account on all the systems, or you can provide the root password via the --password option.

Procedure

• Run the sos collect command and follow the on-screen instructions.

  注意

  By default, sos collect tries to identify the type of cluster it runs on to automatically identify the nodes to collect reports from.

  1. You can set the cluster or nodes types manually with the --cluster or --nodes options.
  2. You can also use the --master option to point the sos utility at a remote node to determine the cluster type and the node lists. Thus, you do not have to be logged into one of the cluster nodes to collect sos reports; you can do it from your workstation.
  3. You can add the --upload option to transfer the sos report to Red Hat immediately after generating it.
  4. Any valid sos report option can be further supplied and will be passed to all sos reports executions, such as the --batch and --clean options.

  [root@primary-rhel10 ~]# sos collect --nodes=sos-node1,sos-node2 -o process,apache --log-size=50
  
  sos-collector (version 4.2)
  
  This utility is used to collect sosreports from multiple nodes simultaneously.
  It uses OpenSSH's ControlPersist feature to connect to nodes and run commands remotely. If your system installation of OpenSSH is older than 5.6, please upgrade.
  
  An archive of sosreport tarballs collected from the nodes will be generated in /var/tmp/sos.o4l55n1s and may be provided to an appropriate support representative.
  
  The generated archive may contain data considered sensitive and its content should be reviewed by the originating organization before being passed to any third party.
  
  No configuration changes will be made to the system running this utility or remote systems that it connects to.

  Please enter the case id you are collecting reports for: <8-digit_case_number>
  
  sos-collector ASSUMES that SSH keys are installed on all nodes unless the
  --password option is provided.
  
  The following is a list of nodes to collect from:
      primary-rhel10
      sos-node1
      sos-node2
  
  
  Press ENTER to continue with these nodes, or press CTRL-C to quit

Verification

• Verify that the sos collect command created an archive in the /var/tmp/ directory matching the description from the command output.

  [root@primary-rhel10 ~]# ls -l /var/tmp/sos-collector*
