Last week, I started converting my app to use ASL, and everything was
hunky dory. For diagnostic purposes, I use an ASL query to export to
text for upload recent logs.
// really, days & flag are passed in to a method
double days = 30.0; // varies from 1.0 to 30.0
NSString *minLevel = [NSString stringWithFormat:@"%u", (flag ?
ASL_LEVEL_ERR : ASL_LEVEL_NOTICE)];
NSCalendarDate *startDate = [NSCalendarDate
dateWithTimeIntervalSinceNow:-24.0*60.0*60.0*days];
NSString *logSince = [NSString stringWithFormat:@"%.0f", [startDate
timeIntervalSince1970]];
aslmsg query = asl_new(ASL_TYPE_QUERY);
asl_set_query(query, ASL_KEY_SENDER, "MyApp", ASL_QUERY_OP_EQUAL);
asl_set_query(query, ASL_KEY_TIME, [logSince UTF8String],
ASL_QUERY_OP_GREATER_EQUAL);
asl_set_query(query, ASL_KEY_LEVEL, [minLevel UTF8String],
ASL_QUERY_OP_LESS_EQUAL | ASL_QUERY_OP_NUMERIC);
aslresponse response = asl_search(client, query);
asl_free(query);
aslmsg message = NULL;
while ((message = aslresponse_next(response)) != NULL) {
// format and append the message
}
aslresponse_free(response);
asl_close(client);
// return the message
Today, I fired up Xcode to continue working, and I noticed my queries
no longer return any messages before this morning's reboot.
The only thing I can think of is that, since last week, the periodic
weekly script ran this morning. Does this script prune the ASL
database? Is there another way to go further back in time with ASL?
TIA.
