Is there a way to change device graphs to 12-hour time?

Title. Currently the graphs only show in 24-hour time. Is there a setting I can change so the graphs can show in 24-hour time?

I have never seen a setting for that… but you can take a look in here

I had a look through it and did not find any setting that would change the graphs to 12hr time. I guess it is not something that is implemented?

I tried changing these settings:

$config[‘alert_graph_date_format’] = ‘%m-%d-%Y %h:%i’
$config[‘dateformat’][‘compact’] = ‘m-d-Y h:i:s’
$config[‘dateformat’][‘byminute’] = ‘m-d-Y h:i’
$config[‘dateformat’][‘time’] = ‘h:i:s’
$config[‘dateformat’][‘mysql’][‘compact’] = ‘%m-%d-%Y %h:%i:%s’
$config[‘dateformat’][‘mysql’][‘date’] = ‘%m-%d-%Y’
$config[‘dateformat’][‘mysql’][‘time’] = ‘%h:%i:%s’

And restarted and it didn’t seem to change anything.

Having a 12 hour clock on a graph would confuse me :grin:

I think you would have to change the way RRD is drawing

The hour as a decimal number using a 12-hour clock (range 01 to 12).

Someone may know if you can do this without breaking your setup,

I had a quick look and it may be possible to use this setting in combination as a config variable using rrdgraph_def_text … or … rrd_opts_array

I would be adding that to here?

This line?

$config[‘rrdgraph_def_text’] = ‘PRINT:vname:%I:%M:%s%p’

No config variables go in config.php and is update proof.

If you modify files that librenms uses you can run into problems down the line, as auto-updating will stop working for that modified file.

Alright. I might back out of this idea then if it will just cause problems.

Just to be clear, you’re saying I can’t edit /opt/librenms/config.php with config variables?

you can modify /opt/librenms/config.php

but if you modify that file you suggested /html/includes/collectd/config.php it may conflict in future updates

Thank you for clarifying and the support.
