940.0. "API-problem. I don't get the whole context.?" by 51336::BERGGREN (Nils Berggren,DC Sweden 876-8287) Thu Aug 24 1995 12:15
this is the last one..... (for the time being :-)
environment:
-------------
VAX-VMS V6.1
PCM V1.6-110
I don't always get the whole context from the event in the action-routine.
In the event, I've defined event context count=8 and context start=1.
The event triggers on the output from a 'SHOW SYSTEM' command (which
is done by printing a file, on the console, containing the output
from a 'SHOW SYS'; this way the context will always be exactly
the same.)
The action routine dumps out on a file all event-data and the context.
Doing some 'SHOW SYSTEM' and comparing the files created, the files
differ from one and other. All the context are not always present, and
the CMEventContext returns different numbers.
Am I doing something wrong?
regards,
Nils
this is the code I use (stripped...):
-------------------------------------------
:
:
/*
** get all event-parameters.
*/
event_name = CMEventName ( event );
event_class = CMEventClass ( event );
event_info = CMEventInfo ( event );
event_text = CMEventText ( event );
event_context = CMEventContext ( event );
event_time = CMEventTime ( event );
event_type = CMEventType ( event );
event_logtime = CMEventLogtime ( event );
event_count = CMEventCount ( event );
event_priority = CMEventPriority ( event );
event_source = CMEventSource ( event );
event_start = CMEventStart ( event );
event_subsystem = CMEventSubSystem ( event );
event_host = CMEventHost ( event );
event_system = CMEventSystem ( event );
event_userdata = CMEventUserdata ( event );
:
: /* here I convert event_time into ascii_time (printable) */
/*
** write all event-data into dat-file
*/
fprintf(logfile, "Event received at %s.\n", current_ascii_time);
fprintf(logfile, "\t Name: %s\n", event_name);
fprintf(logfile, "\t Class: %s\n", event_class);
fprintf(logfile, "\t Text: %s\n", event_text);
fprintf(logfile, "\t Context: %d\n", event_context);
fprintf(logfile, "\t Time: %s\n", ascii_time);

fprintf(logfile, "\t Priority: %d\n", event_priority);
fprintf(logfile, "\t Source: %s\n", event_source);
fprintf(logfile, "\t Start: %d\n", event_start);
fprintf(logfile, "\t Subsystem: %s\n", event_subsystem);
fprintf(logfile, "\t Host: %s\n", event_host);
fprintf(logfile, "\t System: %s\n", event_system);
fprintf(logfile, "\t Userdata: %s\n", event_userdata);
/*
** write context into dat-file.
*/
event_context = CMGetEventContext(event);
fprintf(logfile,"\t Context [%d lines]:\n", event_count);
for (i=0; i<event_count; i++) {
context_line = CMEventContextLine( event, i);
context_line_len = CMEventContextLineLength( event, i);
if (context_line) {
fprintf(logfile, "%s\n", context_line);
}
else {
fprintf(logfile, "_NO_EVENT_CONTEXT_TEXT_\n");
}

| Nils,
The only thought that comes to mind is that perhaps the entire event
context has not been logged prior to sending the event notification to
your program. Perhaps you have defined the context to be 10 lines and when
you got this message there might have been only 1 or 2 lines on the
context logged. Again, this is just a guess on my part.

| And a very good guess as the event context may not always be available
as the Daemon may not have actually flushed it to disk. In my code, I
use a wait-loop when I retrieve the event text and if I don't get all
the context. So check to see if al the context is present and if not
call the get context routine again.
Regs,
Dan
