Function Documentation

m0_iem()

void m0_iem	(	const char *	file,
		const char *	function,
		int	line,
		const enum m0_motr_iem_severity	sev_id,
		const enum m0_motr_iem_module	mod_id,
		const enum m0_motr_iem_event	evt_id,
		const char *	desc,
			...
	)

The function must be called with appropriate parameters using the macros M0_MOTR_IEM() & M0_MOTR_IEM_DESC() to send an IEM alert. This IEM is throttled by a simple throttling scheme. The throttling scheme is the maximum number of IEM alerts for the defined interval.

Parameters

file	from where m0_iem is called, use FILE
function	from where m0_iem is called, use FUNCTION
line	from where m0_iem is called, use LINE
sev_id	a valid value from enum m0_motr_iem_severity
mod_id	a valid value from enum m0_motr_iem_module
evt_id	a valid value from enum m0_motr_iem_event
desc	a string description with variable args. Can be NULL, max (512-1) bytes in length.
