Email notifications about ServiceGuard events

[Mihails Nikitins]

Hi,

I'd like to get email notifications in case of package failover. What is your favourite way to configure it?

Thanks and points in advance for your comments!

BR,

We don't send e-mails but do alert to openview.

We have a very simple approach. We add the commands to alert to openview, though "mailx" would work fine in your case to the "customer_defined_run_cmds" and the "customer_defined_halt_cmds" functions in the package control files.

Hi Mihails,

You need that EMS HA Monitors product - B5736A.
This is an add-on to the standard Event Monitoring Sysstem (EMS) that's included in the Online Diagnostics bundle.
It cam monitor disk, cluster, network & system resources.
It is not a free product however, but is exactly what you're looking for, I'd say.

HTH,
Jeff

Here is a simple solution:

Write a script that performs a 'cmviewcl -v' and the does a diff on the output comparing known good values.

If there is a change, mail or page the admin.

Put the script in cron every minutes.

Of course, simple things like adding a line in package start/stop scripts that mails the admin would work too.

Hope this helps!

Mihails,

Here is an example of the script I mentioned ...

Hope this helps!

Use the customer_defined_halt_cmds section to email you when a pkg is halting (including the nodename it's halting on) and the customer_defined_run_cmds to email you when a package starts on

Example of how to code the package control scripts:

---[ snip ]---
function customer_defined_run_cmds
{
# ADD customer defined run commands.

HOSTNAME=`uname -n`
echo "Package starting on $HOSTNAME" \
| elm -s "ACLK PACKAGE STARTING ON $HOSTNAME" yourname@yourco

test_return 51
}
