disksup(3erl) Erlang Module Definition disksup(3erl) NAME
disksup - A Disk Supervisor Process DESCRIPTION
disksup is a process which supervises the available disk space in the system. It is part of the OS_Mon application, see os_mon(7) . Avail- able for Unix and Windows. Periodically checks the disks. For each disk or partition which uses more than a certain amount of the available space, the alarm {{disk_almost_full, MountedOn}, []} is set. On Unix : All (locally) mounted disks are checked, including the swap disk if it is present. On WIN32 : All logical drives of type "FIXED_DISK" are checked. Alarms are reported to the SASL alarm handler, see alarm_handler(3erl) . To set an alarm, alarm_handler:set_alarm(Alarm) is called where Alarm is the alarm specified above. The alarms are cleared automatically when the alarm cause is no longer valid. CONFIGURATION
The following configuration parameters can be used to change the default values for time interval and threshold: disk_space_check_interval = int()>0 : The time interval, in minutes, for the periodic disk space check. The default is 30 minutes. disk_almost_full_threshold = float() : The threshold, as percentage of total disk space, for how much disk can be utilized before the disk_almost_full alarm is set. The default is 0.80 (80%). See config(5) for information about how to change the value of configuration parameters. EXPORTS
get_disk_data() -> [DiskData] Types DiskData = {Id, KByte, Capacity} Id = string() KByte = int() Capacity = int() Returns the result of the latest disk check. Id is a string that identifies the disk or partition. KByte is the total size of the disk or partition in kbytes. Capacity is the percentage of disk space used. The function is asynchronous in the sense that it does not invoke a disk check, but returns the latest available value. Returns [{"none",0,0}] if disksup is not available. get_check_interval() -> MS Types MS = int() Returns the time interval, in milliseconds, for the periodic disk space check. set_check_interval(Minutes) -> ok Types Minutes = int()>=1 Changes the time interval, given in minutes, for the periodic disk space check. The change will take effect after the next disk space check and is non-persist. That is, in case of a process restart, this value is forgotten and the default value will be used. See Configuration above. get_almost_full_threshold() -> Percent Types Percent = int() Returns the threshold, in percent, for disk space utilization. set_almost_full_threshold(Float) -> ok Types Float = float(), 0=<Float=<1 Changes the threshold, given as a float, for disk space utilization. The change will take effect during the next disk space check and is non-persist. That is, in case of a process restart, this value is forgotten and the default value will be used. See Configuration above. SEE ALSO
