9.10. The multi_trepctl Command

The multi_trepctl command provides unified status and operation support across your Tungsten Replication installation across multiple hosts without the need to run the trepctl command across multiple hosts and/or services individually.

multi_trepctl
backups [ --by-service ] [ --fieldsappliedLastSeqNoappliedLatencyhostroleserviceNamestate ]
heartbeat [ --host, --hostsself ]

masterof [ --outputjsonlistnametabyaml ] [ --path, --paths ] [ --role, --roles ]
run [ --service, --servicesself ] [ --skip-headers ] [ --sort-by ]

The default operation, with no further command-line commands or arguments displays the status of all the hosts and services identified as related to the current host. In a typical single-service deployment, the command outputs the status of all services by determining the relationship between hosts connected to the default service:

shell> multi_trepctl
| host   | serviceName | role   | state  | appliedLastSeqno | appliedLatency |
| tr-ms1 | alpha       | master | ONLINE |               54 |          0.867 |
| tr-ms2 | alpha       | slave  | ONLINE |               54 |          1.945 |
| tr-ms3 | alpha       | slave  | ONLINE |               54 |         42.051 |

On a server with multiple services, information is output for each service and host:

shell> multi_trepctl 
| host  | servicename | role   | state         | appliedlastseqno | appliedLatency |
| east1 | east        | master | ONLINE        |               53 |          0.000 |
