Template for nagios services alerts

Help
1

After searchingon docs / forum / google.
Can not find a nice template example for nagios service notification.
The use of
@foreach ($alert->faults as $key => $value) @endforeach
Does not provides nothing.
Currently I have multiple nagios services forced to be on critical state assigned to localhost device.
Created an alert rule using the Service up/down rule (included in collection) and assign telegram transport.
Notifications are being sent ok.
But … can not create a nice template.
Following template documentation can not get specific info for each critical state service.

BTW:
1_Using API can check sevice id , state ,etc , so I think it should be possible to add this info on template.
2_I can succesfully create my personal templates with regular snmp alarms.

Leandro.

Ok … just to update my status:
so far, I have following template:

ALERT: {{ $alert->name}}
Severity: {{ $alert->severity }}
Estado: {{ $alert->state}}
ID: {{ $alert->id}}
UID: {{ $alert->uid}}
rule: {{ $alert->rule }}
Timestamp: {{ $alert->timestamp }}
Time elapsed: {{ $alert->elapsed }}

According to this and %services.service_status , describe at template documentation.
I will need to create a warning and critical alert rule and warning and critical template per service.
This does not sounds good to me … I need to monitor more than 15 hosts.

Hope to find more suitable solution,
Regards,
Leandro.

I don’t know how well this would fit in your environment, but I have a single alert template to cover both warning and critical service alerts. The template below plus the two alert rules works fine for the 20+ monitored services.

HTH

Severity: {{ $alert->severity }}
Rule: @if ($alert->name)
{{ $alert->name }}
@else
{{ $alert->rule }}
@endif
@if ($alert->state == 0)
Time elapsed: {{ $alert->elapsed }}
@endif
Timestamp: {{ $alert->timestamp }}
Unique-ID: {{ $alert->uid }}

@if ($alert->faults)
Faults:

@foreach ($alert->faults as $key => $value)
#{{ $key }}: Service: {{ $value['service_ip'] }}
Description: {{ $value['service_desc'] }}
Message: {{ $value['service_message'] }}

@endforeach 
@endif

Your best bet is to use the built-in test-template.php (see https://docs.librenms.org/Alerting/Testing/). This will dump everything including the entire contents of the faults array to the command line so you can see what is available e.g. (severely cropped for brevity):

/opt/librenms/scripts/test-template.php -t 12 -d -h localhost -r 8

    [faults] => Array
        (
            [1] => Array
                (
                    [device_id] => 1
                    [hostname] => localhost
                    .....
                    [service_id] => 17
                    [service_ip] => www.blah.com
                    [service_type] => http
                    [service_desc] => check_http: HTTPS request check for external connectivity.
                    [service_param] => -S
                    [service_ignore] => 0
                    [service_status] => 2
                    [service_changed] => 1570347014
                    [service_message] => CRITICAL - Socket timeout after 10 seconds
                    etc....
