Email Notification - Client Specific Naming in Subject / Body

Help
1

Hello,

After considerable digging around I am not finding where I can make overrides to the alarm notifications that would make it clear which server this is coming from.

We have 4 client servers and are not connected to the cloud service. We are getting notifications however since all 4 servers have a hostname of ‘servermatter’ we can’t tell which one the email is coming from.

We have learned and tested if we run the command:
/usr/libexec/netdata/plugins.d/alarm-notify.sh sysadmin MYDOMAIN.COM 1 1 1 1661824572 test_alarm test.chart test.family WARNING CLEAR 100 90 /usr/libexec/netdata/plugins.d/alarm-notify.sh 1 1 units ‘ServerMatter Alarm - This Is Only A Test Verifying Notifications Work’ ‘PASSED’ ‘old value’ ‘evaluated expression’ ‘expression variable values’ 0 0

It succeeds in accomplishing our goal:
2022-12-18 21:38:59: alarm-notify.sh: INFO: sent email notification for: MYDOMAIN.COM test.chart.test_alarm is WARNING to ‘admin@servermatter.com’

However we have not been able to find where to insert this type of customization for all our ‘real’ alarms.

What sayeth the group?

Thanks.

Hi @servermatter !

Can you try the following if it works for you?

In each node’s /etc/netdata/netdata.conf, can you edit (and uncomment) the entry registry hostname and add there a custom hostname for each?

It should then use that for notifications on the subject in place of Critical, disk_space_usage = 100%, on XXXXXXX. The same string should appear in place of now servermatter under the disk_space_usage.

Hello and thanks for the response. Very much appreciated.

I would not want to completely replace the entire line 'Critical, disk_space_usage = 100%, on XXXXXXX` but only the XXXXXXX portion of it. Is that what you mean?

I am testing it now.

OK, follow up. I interpreted hostname as using my own desired hostname. However you started me in the right direction. I found this page Registry | Learn Netdata and ended up getting the following to work as perfectly as I’d hoped

[registry]
    registry hostname = mydesiredidhere

Thank you. Impressive response time which is rare in todays world.
