KUMOSTAT(1) General Commands Manual KUMOSTAT(1) NAME
kumostat - get kumofs status SYNOPSIS
kumostat server-address[:port=19800] command kumostat -m manager-address[:port=19700] command DESCRIPTION
Get status from Server node. COMMANDS
pid get pid of server process uptime get uptime time get UNIX time version get version cmd_get get total number of processed get requests cmd_set get total number of processed set requests cmd_delete get total number of processed delete requests items get number of stored items rhs get rhs (routing table for Get) whs get whs (routing table for Set/Delete) hscheck check if rhs == whs set_delay maximize throughput at the expense of latency unset_delay maximize throughput at the expense of latency DELAY MODE
If the delay mode is enabled, req/sec throughput is maximized at the expense of latency. This mode actually disables TCP_NODELAY option of all sockets. The practice of this feature is as following: - run some scripts that watches load of the kumo-server. (see source code of kumotop) - if the load of kumo-server becomes high, enable delay mode by kumostat set_delay command. - if the load of kumo-server becomes low, disable delay mode by kumostat unset_delay command. EXAMPLE
$ kumostat svr1 items $ kumotop -m mgr1 hscheck SEE ALSO
