openipmi_eventd - An IPMI event handler
openipmi_eventd <domain name>
<connection parms> <options>
<program> [<parm1> [<parm2> [...]]]
The openipmi_eventd program listens for IPMI events for the
given connection and sends them to another program to process, or to a
file.
- <domain name>
- The name to use for the OpenIPMI domain. This will appear in logs and some
names.
- <connection parms>
- The parameters for the connection depend on the connection type. These are
all described in openipmi_conparms (7)
- <options>
- Zero or more of the options defined in OPTIONS below.
- <program> [<parm1> [<parm2> [...]]]
- The program to run. This must be the full path to the program. Any given
parameters are passed to the program before any IPMI parameters.
- -f filename, --outfile
filename
- Send all events to the given file
- -k,
--exec-now
- Immediately spawn the given program and send the event information to that
program's standard input. The program should not quit, if it does then
this program will exit with an error.
- -i,
--event-stdin
- Send the event information to the program's standard input instead of the
commandline.
- -e,
--delete-events
- Delete events from the SEL (System Event Log) once they have been
processed. Note that the program has to have handled the event without
error for the event to be deleted. Otherwise the events are not deleted
from the SEL.
- -b,
--dont-daemonize
- Do not daemonize the program, run it as a foreground process.
- -d, --debug
- Debug the program, turn on output, send all logs to stderr, and do not run
the process as a daemon.
When started, this program will connect to the given IPMI domain,
ignore all existing logs, and set up to listen from logs from all sources.
When an event comes in, it will handle the event depending on how it is
configured.
By default the program will be called on each log and the event
information passed on the program's command line. The first parameter (after
the ones given on the openipmi_eventd command line) will be the event
type, the rest are key-value pairs as defined below.
If -i is given on the commandline, instead of passing in
the event information on the command line, it will be passed into the
program's standard input. The first line will be the event type, and each
line will have a key-value pair up until the last line, which will be
endevent.
If -k is given on the command line, the program will be
started immediately and expected to take events on its standard input as
they come in. Each event will start with an event type, contain key-value
pairs, and end in endevent.
The first line and parameter of an event is always the event type
(either threshold , discrete , or unknown ). Then the
following then the following, in no particular order. When sending to a
file, or another program via standard input, endevent will mark the
end of an event.
- assert true|false
- If true, the event is being asserted (the alarm present). If false, the
alarm was present but has now gone away.
- eventtype <num>
- The event type, per the IPMI specification.
- eventtime <num>
- The time (in seconds) for the IPMI event. It is 64 bits.
- eventdata <vals>
- The raw event data, vals is a list of hex numbers.
- id <name>
- The OpenIPMI id of the sensor. This is in the format:
<entity_id>.<entity_instance>.<sensor_name> where
the entity id and instance identify the object being monitored and the
sensor names comes from the sensor. Only for discrete and threshold
events.
- val <floatnum>
- The sensor value that cause the event, in floating point format. Optional
and only present for threshold sensors.
- raw <hexnum>
- The sensor value that cause the event, in raw (hex) format. Optional and
only present for threshold sensors.
- off <num>
- The bit in the sensor that caused the event, only present for discrete
sensors.
- severity
- The severity of the event. For discrete sensors this optional and is a
number between 0 and 14. Them meaning depends on the specific sensor type.
For threshold sensors this is one of:
- prevseverity
- for discrete sensors.
- direction
- The direction of the event, only for threshold sensors. This can be
difficult to understand and is not consistent on IPMI systems. The IPMI
specifiation does define what this means. For instance, what does an
assertion of an upper critcal event going low mean?
