Hi Tom,

it works like a charm.

Actually, having some migration hints from the legacy alerting features would be very useful, but I guess it requires a bit of your free time :-)

Thanks for your effort!

King Regards,

Stefano

Hi Stefano,

The old alerting system did more than host up/down, but this was probably the biggest hurdle for people to being able to disable the legacy system.

I'm going to have a look if the old one did anything the current one can't do with checkers but I think there might be nothing left.

If you were relying on the legacy system for host up/down only, you can definitely turn it off.

- Entity type: Device
- Checker condition: device status = 0
- Host match: * (or whatever you want to monitor, only)
- Entity match: *

will give you host up/down alerting.

Hi Tom,

if I understood correctly, does this metric replace the legacy up/down alerting system?

Thanks,

Yup, you need a more recent version, device entity was added 17/4.

Hi Tom,

Actually we haven’t updated in a while (we are an ITIL shop and updating can be a pain). Here is our version:

[root@yoda observium]# svn info /opt/observium/includes/definitions/entities.inc.php |grep ^Last

Last Changed Author: sid3windr

Last Changed Rev: 5005

Do we need to update?

Erik,

Are you on the latest version? (It's probably not in the stable branch yet?)

root@observium1:~# svn info /opt/observium/includes/definitions/entities.inc.php |grep ^Last

Last Changed Rev: 5331

root@observium1:~# grep device /opt/observium/includes/definitions/entities.inc.php
$config['entities']['device']['id_field']             = 'device_id';

Hi,

Is there a way for using the new alerting system to send an e-mail when a device goes down?

I see in the wiki that there is a “device_status” metric, but I can’t figure out how to use it. There is no “Device” entity type when I try to make a new alert checker.

Is this feature still in development?

Erik
