Linux-Heartbeat Email Notification

kopper27 · 05-03-2010, 02:02 PM

hi guys

I hope this goes here

Have someone used Linux heartbeat to send email when the Slave server becomes the Master?
I've read I can configure the MailTo under

/etc/ha.d/resource.d

but I really don't know how to do it.
I basically need my primary server to send an email when it becomes inactive and all the activities are manage by the secondary node

thanks a lot

Hello,

I think you're looking for this:
MailTo HeartBeat

Kind regards,

doing more research looks like adding this

Code:

MailTo::name1@some.com,another@bla.org

to

Code:

/etc/ha.d/haresources

works?

can someone tell me if it is that simple?

thanks a lot

Hi,

If I'm correct you have to set something up like this in both nodes (in the haresources file):

Code:

primitive mail ocf:heartbeat:MailTo \
        params email="youremail@yourdomain.com" \
        params subject="Cluster Failover"

This will result in an email being sent out whenever the node is taking over resources, meaning the other one is down/failing/dead. So when you receive a mail, you'll automatically see from whom it's coming (root@hostname or something like that) and will know that there has been a 'takeover' of resources.

Kind regards,

Eric

thanks in that case as soon as I have some time I will have to test it

Hi,

Please let us know the results. Also check which mail command is used on your system and that it accepts the parameters issued by the script (-s is not always accepted according to some sites).

Kind regards,

Eric
