Hi all,

Does anyone have opinions on timezone adjustments per host or service?

We are wanting to replace our current in-house monitoring with nagios, but
our single monitoring system pushes thousands of checks out to sites in half
a dozen different timezones every hour. Some of these checks are timezone
sensitive, whilst others aren't.

I propose that service & host have "timezone" & "use_timezone"
attributes. Below is an example of how i'd [poorly] calculate a tz_offset
based on the "timezone" attribute.

Thoughts?

Cheers,
Grant


/* get the timezone difference between local time & the given timezone */
long get_timezone_offset(const char *tz){
char *tzlocal;
struct tm t;
time_t secs_since_epoch;
long local_utc_offset, remote_utc_offset;

/* save existing timezone data, if exists & grab seconds elapsed since
the EPOCH */
tzlocal=getenv("TZ");
secs_since_epoch=time(NULL);

/* get local offset from UTC, in seconds */
tzset();
localtime_r(&secs_since_epoch,&t);
local_utc_offset=secs_since_epoch-mktime(&t);

/* set our timezone to remote timezone */
setenv("TZ",tz,1);
tzset();
localtime_r(&secs_since_epoch,&t);

/* restore original timezone */
if(tzlocal!=NULL)
setenv("TZ",tzlocal,1);
else
unsetenv("TZ");
tzset();

/* get remote offset from UTC, in seconds */
remote_utc_offset=secs_since_epoch-mktime(&t);

return (local_utc_offset-remote_utc_offset);
}
