Smokeping missing from latency tab

[pmal]

I have Smokeping up and running after following the instructions here - Smokeping - LibreNMS Docs

The smokeping interface is visible and working correctly in /smokeping , with all the graphs etc - but I don’t see smokeping in the Latency tab on the device. It did appear briefly during the install, but it disappeared (possibly when I did the config changes related to “Share RRDCached with LibreNMS”).

Is this intentional? Should smokeping no longer appear in the Latency tab? or is there a config change I need to make?

validate.php mostly comes back clean, except for the following:

Relevant section of config.php:

$config['smokeping']['dir'] = '/opt/librenms/rrd';
$config['smokeping']['pings'] = 20;
$config['smokeping']['probes'] = 2;
$config['smokeping']['integration'] = true;
$config['smokeping']['url'] = 'smokeping/';  // If you have a specific URL or pa
th for smokeping

I found the problem, documenting here if anyone else hits this - I had the wrong directory specified in the config - looks like librenms doesn’t show smokeping in the Latency tab if it can’t find the files; I changed:

$config['smokeping']['dir'] = '/opt/librenms/rrd';

to:

$config['smokeping']['dir'] = '/opt/librenms/rrd/smokeping';

and it now works.
