Hum so you used the port down alert with a high port bandwith limit (to avoid spam alerts right ?) … I thought about it during my test session but I was certainly configuring it wrong ! I’ll test it now on my dev server and keep you up to date :-)

BTW my question about a roadmap for “official” host down support on alert module is still available.

Hi Bertrand,

No needs to use alert module for that.

On SVN4574 the alert for host down is working. You'll just have to set some stuff on config.php :

$config['alerts']['email']['default'] = "alerts@example.commailto:alerts@example.com"; $config['email_from'] = "Observium <obs@example.commailto:obs@example.com>"; $config['email_backend'] = "smtp"; $config['email_smtp_host'] = 'mail.example.com'; $config['email_smtp_port'] = 25; $config['alerts']['email']['enable'] = TRUE; $config['alerts']['port']['ifdown'] = TRUE; // Port Bandwith $config['alerts']['port_util_alert'] = TRUE; $config['alerts']['port_util_perc'] = 85;

With such configuration you will get alert : host down / up.

Otherwise on Alert menu (just after Observium logo; click on Globe) you can define alerts.

By the way don't forget to se email on SNMP to where alert it should go... :p

I’m a security administrator from a French insurance company and me and my collegues are interested in your powerful monitoring tool. I’ve tested it recently and was amazed by the pretty easy installation of such an intuitive software :-) I’ve also discovered your splitting editions and your intentions for the future and agree with that. The pricing is correct in front of all the work you (all the devs) have done.

The only things I would to know to convince my chief that it’s the tool we need, is : do you have a roadmap for the alerting module ? Because, if I’ve correctly understood, you have done a successful Kickstarter campaign to implement the alerting module, but from my last tests (one of the last free SVN edition, something like r4400) the alerting module wasn’t really enabled, even after changing the config.php and setting the mailing alerts (with the right SMTP relay, recipient, etc…).

Another question is, when (or how if I’ve done it wrong …) do you plan to enable mail alerts for hosts down ?

I didn’t search in all your archives (only the last months) but I’m sorry if the questions was already asked … and I’m sorry for my rough English …

Thank you in advance for your answer(s),

Adrien Bertrand Information security administrator BPCE Assurances

Hi :) I am Frenchy and I don't like last name in Caps :p Maybe some "internal" thing (sic) that on some company want last name in caps. Don't try to know why... but...

Xavier

What on earth are you lot talking about?

Haha, I like the fact that you also have 2 first names. :>

Most likely not all French-speaking people do it (Walloons don't, but I've seen people from France, Switzerland, Canada do it) but if someone does it, almost certainly they're French :-)

*waves the offtopic flag* :D

But yes, we have 2 types of alerting currently - the old, sucky one, which can notify you of host down, and the new one, which is even better than GTA5, but just like GTA5 is not yet finished, and can currently not alert on host down YET. ;-)

Ahah yes it's du to my compagny that my last name is in all caps :-) But even in France people are confused with my first and last name, so I'm now used to it.

Anyway, if I understand : $config[alerts][alerter]... => related to the new awesome GTA5-ish alert module $config[alerts]... => related to the old one I'm right ?

And no clue about a roadmap for the alert module ? (Sorry I know that I'm repetitive).

Hello Adrien,

currently I'm using the rev.4584 and I get alerts when a host is down, the related lines in my config.php are the following:

$config['alerts']['email']['enable']       = TRUE;

$config['alerts']['email']['default']      = "mymail@mydomain.con";

As you can see, I didn't specified anything about the SMTP server and other settings because I'm using the Observium server itself for sending emails (this is a test environment).

I'm not totally sure but it seems to me that the "send an email when a host is down" feature is different from the alerting module (http://www.observium.org/wiki/Alerting) [1].

Of course, the official developers can improve my answer!

Yeah. You're using the historic notification stuff, which we're trying to replace.

At the moment the alerting system doesn't do anything at the host level, only on entity level (port, mempool, port, etc).

Ok thanks :-)

I'll follow this closely. There's maybe a trick to use the alert (for port for instance) to know if a host is down no ?

Ports don't go down when the device does, because polling does not go through. :-)

Could be a false alert, because the port could be up but the device may not be reachable from your Observium server - alerting on port down would be lying and could probably confuse you while troubleshooting.

Is the historic system maintained in the latest release or is already discarded? I haven't yet updated the server and the host-down notifications are very useful for my job.

I haven't removed it... :)
