Convert NOTIFY_SHORTDATETIME to UTC Timezone

[axs819 (Ray)]

Hi,

We have a client system using BST as timezone. However we want to change the date output of NOTIFY_SHORTDATETIME to be in UTC in our Python custom notification script.

Has anyone had success with this?

On my system the relevant variables are

NOTIFY_SHORTDATETIME=2020-08-17 17:19:41
NOTIFY_LONGDATETIME=Mon Aug 17 17:19:41 CEST 2020
NOTIFY_MICROTIME=1597677581260409

• NOTIFY_SHORTDATETIME doesn’t contain timezone information which makes the conversion to UTC at least difficult.

• NOTIFY_LONGDATETIME could be used instead becaue it contains timezone information. There are various Python modules and functions that can parse such strings, for example dateutil.parser.parse or datetime.datetime.strptime.

• NOTIFY_MICROTIME already is in UTC and fits best:

  import os, datetime
  ts = int(int(os.environ.get('NOTIFY_MICROTIME')) / 1000000)
  dt_object = datetime.datetime.fromtimestamp(ts)

BTW: you can have a single monitoring site running in a different time zone than the monitoring server by setting the TZ environment variable in $OMD_ROOT/etc/environment.

Thanks, this worked for me.

import os, datetime
ts = int(int(os.environ.get('NOTIFY_MICROTIME')) / 1000000)
dt_object = datetime.datetime.utcfromtimestamp(ts)
