sending alerts to a callback server

[Marc Sanson]

Hi,

I try to send alert messages to a tcp server.

The messages which comes across includes an id like alert00 and a plain message text. I just wondering why the alert type and name is not sent.

Does anybody knows how that information can be included ?

Thanks a lot for your support.

Can you provide some detail on how you are sending the alerts to the tcp server? Do you mean Cloverleaf alerts? do you invoke a tcl proc as the action or do you send an email?

Hi Pete thanks for your answer, Yes I’m talking about Cloverleaf alerts see attached screenshot.

I just send the alert to a callback and configure the callback to my TCP server socket.

Sorry – I have never used this. Will it be used to report to an enterprise monitoring solution?

I will try this out as well.

Yes in deed, exactly the plan we want to feed Nagios.

I tried to set up the same thing – but my server thread configuration must be different than yours – i used a protocol of tcpip and saw an error message in the process log:

Length encoding wrong?; read len of 892697977

Then I tried pdl-tcpip, and got these messages:

[pdl :PDL :WARN/0:     fr_alert:08/29/2013 08:44:39] match phrase basic-msg rejected

[pdl :PDL :ERR /0:     fr_alert:08/29/2013 08:44:39] no-match: no more phrases to try

How did you even get the text that you got? Did you use mlp_tcl as the pdl?

Is Nagios expensive?

We use Nagios to monitor Cloverleaf and many other applications.

In our setup (it may be the default) Cloverleaf cannot connect directly. Cloverleaf executes a command ‘send_nsca’ with various parameters.

Hi Pete,

I wondering there you set the protocol in your alert configuration.

I just select callback and if the condition which is configured is evaluated to true a message like

{alert00 {The percent of disk space used for C: is more than 0, currently 63 }}  is send to the configured socket.

as far as i know Nagios is free of charge

Hi Richard thanks for the answer, could you provide some more details on send_nsca and how you configure that.
