Troubleshooting sgadmin

Cluster not reachable

If the cluster is not reachable at all by sgadmin, you will see the following error message:

Search Guard Admin v5
Will connect to localhost:9300
ERR: Seems there is no elasticsearch running on localhost:9300 - Will exit


  • Check the hostname of your cluster
    • By default, sgadmin uses localhost
    • If your cluster runs on any other host, specify the hostname with the -h option
  • Check the port
    • Check that you are running sgadmin against the transport port, not the HTTP port
    • By default, sgadmin uses 9300
    • If you’re running on a different port, use the -p option to specify the port number

None of the configured nodes are available

If sgadmin can reach the cluster, but there are issues uploading the configuration, you will see the following error message:

Contacting elasticsearch cluster 'elasticsearch' and wait for YELLOW clusterstate ...
Cannot retrieve cluster state due to: None of the configured nodes are available: [{#transport#-1}{mr2NlX3XQ3WvtVG0Dv5eHw}{localhost}{}]. This is not an error, will keep on trying ...
   * Try running with -icl and -nhnv (If thats works you need to check your clustername as well as hostnames in your SSL certificates)
   * If this is not working, try running with --diagnose and see diagnose trace log file)
   * Add --accept-red-cluster to allow sgadmin to operate on a red cluster.


  • Check the cluster name
    • By default, sgadmin uses elasticsearch as cluster name
    • If your cluster is named differently either:
      • let sgadmin ignore the cluster name completely by using the -icl swith or
      • specify the name of your cluster with the -cn switch
  • Check the hostname and hostname verification
    • By default, sgadmin will verify that the hostname in your node’s certificate matches the node’s actual hostname
    • If this is not the case, e.g. you’re using demo certificates
      • disable hostname verification by adding the -nhnv switch
  • Check the cluster state
    • By default, sgadmin ony executes when the cluster state is at least yellow
    • If your cluster state is red, you can stll execute sgadmin, but you need to add the -arc/--accept-red-cluster switch
  • Check the Search Guard index name
    • By default, Search Guard uses searchguard as the name of the confguration index
    • If you configured a different index name in elasticsearch.yml, you need to specify it with the -i option

Using the diagnose switch

If you cannot find out why sgadmin is not executing, add the --diagnose switch to gather debug information, for example

./ -diagnose -cd ../sgconfig/ -cacert ... -cert ... -key ... -keypass ...

sgadmin will print the location of the generated diagnostic file:
