Beekeeper::Service::Supervisor::Worker - Worker pool supervisor
Version 0.09
A Supervisor worker is created automatically in every worker pool.
It keeps a shared table of the performance metrics of every worker connected to every broker, and routinely measures the CPU and memory usage of local workers.
These metrics can be queried using the methods provided by Beekeeper::Service::Supervisor or using the command line client bkpr-top.
Number of received notifications per second.
Number of processed calls per second.
Number of errors per second generated while handling calls or notifications.
Resident non shared memory size in KiB. This is roughly equivalent to the value of RES minus SHR displayed by top.
RES
SHR
top
Percentage of CPU load (100 indicates a full utilization of one core thread).
Percentage of busy time (100 indicates no idle time).
Note that workers can have a high load with very little CPU usage when being blocked by synchronous operations (like slow SQL queries, for example).
Due to inaccuracies of measurement the actual maximum may be slightly below 100.
Beekeeper::Service::Supervisor, which is the interface to the RPC methods exposed by this worker class.
