IpmbSensor : Add PollRate property. In existing IpmbSensor code, pollrate value is fixed as 1 sec. We have OCP YosemiteV2 target which has 4 removable host, each host has 70(x4) sensors. More number of sensor will leads to CPU usage. Also IPMB Version does not require to read the version for every second. Therefore, pollRate property can be added in the EM file and based on those values each sensor/version can be read and updated. Hence CPU utilization also reduces. CPU load - pollRate is 1 sec. PID PPID USER STAT VSZ %VSZ %CPU COMMAND 323 1 root R 8200 2% 16% /usr/bin/ipmbsensor CPU load - pollRate is 5 sec. PID PPID USER STAT VSZ %VSZ %CPU COMMAND 294 1 root S 8124 2% 6% /usr/bin/ipmbsensor TESTED: Tested in yosemitev2 by giving different PollRate to each sensor and verified.

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
