LaravelCaffeine\Dripper::getAgeThresholdAttribute() error

ReVoLt112 · 13 November 2021 04:36

my Installation stopped working over night, probably issued by daily.sh?

The relevant output of librenms.log:

Sorry for editing, i struggled with preformatted text

ReVoLt112 · 13 November 2021 05:29

Solved it myself…

The issue was this commit: #13505

i manually set the session lifetime back to 120 and everything is working fine now

murrant · 13 November 2021 15:28

Hmm, that shouldn’t happen. Probably an upstream bug. I’ll see if I can work around it.

murrant · 13 November 2021 15:41

Here is the relevant upstream code:

github.com

GeneaLabs/laravel-caffeine/blob/9023b3bd8015e8d81c9893bff3223b76e628cb4d/src/Dripper.php#L26-L29

    
      
          public function getAgeThresholdAttribute() : int
          {
              return (config('session.lifetime', 32) - 2) * 60000;
          }

The only way for it to return a float is if you set your session lifetime to a float. I wonder what is going on. If anyone else is seeing this error, please chime in. Looks like a one off issue to me.

ReVoLt112 · 13 November 2021 17:25

I am using a 32 Bit Linux Distro (Raspbian) could it be the reason?

murrant · 13 November 2021 17:30

could be, can you run lnms tinker --execute='dump((43800 - 2) * 60000)'

ReVoLt112 · 13 November 2021 19:00

librenms@server01:~$ lnms tinker --execute='dump((43800 - 2) * 60000)'
^ 2627880000.0
librenms@server01:~$

A float

P_Speers · 14 November 2021 00:34

I am having the same error, it just started today. I didn’t try the "manually set the session lifetime back to 120 " as I don’t know where or how to do that
Any help getting this going again would be great. I have tried the git pull and ./daily.sh to see if that would help, nothing. Also validate has no errors as well

P_Speers · 14 November 2021 00:40

Took another look and saw the change was made to the /config/session.php file so I applied the same change and I now have a GUI again
Yeah!!

Yesterday Librenms was working like a charm, got up this morning and was presented with this page:

The librenms is running on rasbian with the latest stable as far as I know.
So, what should I do? I think daily.sh runs by it self every now and then as well.

daand · 14 November 2021 09:36

Same here. .validate and .daily working but GUI down. On an up-to date Rasberry Pi OS (Buster). Pollers still collecting data without issue since RRD graphs can be viewed outside of the LibreNMS GUI.

Anders_Ostling · 14 November 2021 09:45

+1
Raspi 3B with LibreNMS 21.11.04
Git up-2-date
Nothing in the logs
Validate and daily both runs without any errors

TheGreatDoc · 14 November 2021 10:55

@Raspbianuser @daand @Anders_Ostling I’ve moved your posts to another thread.

Check up to see a possible solution.

hikariuk · 14 November 2021 11:10

Another voice to the choir; LibreNMS stopped working overnight.

A little digging suggests the problem is that the default value of session.lifetime is 43800, which is getting multiplied by 60000 in the Dipper code, putting it outside the bounds of an integer.

It looks like one side or the other has changed the interpretation of that value from seconds to minutes, or vice versa. I’ve not dug through the revision history to figure out which one it is.

A quick fix seems to be setting SESSION_LIFETIME in your .env file to something that Dripper accepts, like its default value of 32.

Raspbianuser · 14 November 2021 11:21

Thanks, got it working again!

Talkabout · 14 November 2021 12:16

“35793” is the maximum value you can set on a 32bit PI. I did that in my .env file:

SESSION_LIFETIME=35793

and everything is working again.

murrant · 14 November 2021 13:59

Still baffled by this. Integer overflow = return float??? Crazy stuff there PHP… PHP: Integers - Manual

Thanks for checking out the max @Talkabout I will change the default to 24 days (34560).

Luk3000 · 14 November 2021 14:47

Same problem at my side
Librenms worked like a charm until yesterday (13/11) morning on a Raspberry.

Error in librenms.log
[2021-11-14 15:17:13] production.ERROR: Return value of GeneaLabs\LaravelCaffeine\Dripper::getAgeThresholdAttribute() must be of the type int, float returned {“exception”:"[object] (TypeError(code: 0): Return value of GeneaLabs\LaravelCaffeine\Dripper::getAgeThresholdAttribute() must be of the type int, float returned at /opt/librenms/vendor/genealabs/laravel-caffeine/src/Dripper.php:28)

validate is Ok, daily works, poller works but is GUI down!

Luk3000 · 14 November 2021 14:58

Ok problem solved
Added SESSION_LIFETIME=35793 to /opt/librenms/.env
GUI works again.

Thx to the Great Spirits!
