Traceroutes in email alerts

Help
1

Hello,

I’m trying to set up notification emails to include a traceroute, but am having problems getting this working. What I’ve tried so far is as follows:

  1. Edit ‘/opt/librenms/config.php’ and include the following (note that the OS is Arch Linux and tracepath is the replacement for traceroute):
    $config['debug']['run_trace'] = true;
    $config['traceroute'] = '/usr/bin/tracepath';

  2. Add the following to the alert template (taken from the documentation):
    {{$alert->debug['traceroute']}}

Is there something I’m missing?

Thanks.

user@server:/opt/librenms$ sudo ./validate.php

tracepath does not accept the same options as traceroute. Just install traceroute.
Also, your php SSL is not working
And you have an issue with your login shell in /etc/passwd
among other issues with your install.

This error is caused by the version of composer downloaded and installed into the /opt/librenms directory by running ./validate.php. It doesn’t look like this version gets automatically updated, so if I remove it completely and re-run ./validate.php, a new version gets downloaded. This has been causing problems for some time. Would it make more sense to use the system version of composer?
