SingleStore DB


List information about all MemSQL Ops nodes in the cluster. This command can be used to filter MemSQL Ops nodes based on SingleStore DB database roles.

This command can be used in conjunction with other memsql-ops commands to achieve more robust functionality. Here is a simple example:

memsql-ops memsql-list --agent-id Ad916a -q | xargs -n 1 memsql-ops memsql-restart --no-prompt

This command will restart all SingleStore DB nodes running in a particular agent with ID prefixed by Ad916a.

usage: memsql-ops memsql-list [--settings-file SETTINGS_FILE] [-q] [-j]
                              [-r {leaf,aggregator,master} [{leaf,aggregator,master} ...]
                              | --availability-group {1,2}]
                              [--agent-id AGENT_ID | --local]

List SingleStore DB nodes in the cluster.

optional arguments:
  --settings-file SETTINGS_FILE
                        A path to a MemSQL Ops settings.conf file. If not set,
                        we will use the file in the same directory as the
                        MemSQL Ops binary.
  -q, --quiet           Only display SingleStore DB ids.
  -j, --json            Print output as JSON.
  -r {leaf,aggregator,master} [{leaf,aggregator,master} ...], --memsql-role {leaf,aggregator,master} [{leaf,aggregator,master} ...]
                        Only list SingleStore DB nodes with the specified role.
  --availability-group {1,2}
                        Only show leaves in the specified availability group.
  --agent-id AGENT_ID   Only list SingleStore DB nodes that are collocated with the
                        specified agent.
  --local               Only list SingleStore DB nodes which are on the local MemSQL
                        Ops agent.
                        Include nodes that we have unmonitored.
