Slow computer listing and high CPU with version 1.5.1.01798

[Tom Elliott]

@rogalskij I don’t know OS:

PHP error logs
/var/log/php-fpm/www-error.log (redhat based)
/var/log/apache2/error.log (debian based)

SQL:
SELECT * FROM history;

I doubt the sql will be of much help, but anything is better than nothing.

Most of the logs I’ve gotten this far don’t appear to have anything and maybe none of them do, in which case I don’t know when the issue was directly introduced.

If anyone is able to bisect known good and the obvious current as the starting bad to figure out when it got introduced?

I’m assuming we’ve all tried reverting to the first known good and verified it is still “good” as well?

Basically if someone doens’t mind taking where they know they’re broken, and iterating back to when it works great to exactly when it fails, it may help us figure out where to start otherwise I’m currently flying blind.

@Tom-Elliott I collected both log files and sent them to you directly via “Chat”. you should see all of them in there. Thanks so much for investigating this issue.

Is everyone having this particular problem consistently using the LDAP plugin by chance?

[rogalskij]

@Tom-Elliott Yes we utilize the LDAP Plugin for all logins. Version 1.5.5, I will tried logging in with a local account but the slowness persisted.

A test for anyone having this issue. I did a little trouble shooting, and if you go to: Reports > Pending Mac List and approve all the pending mac addresses at once, performance improved somewhat.

I am unsure if this is coincidental but for me my “Hosts” tab is now much more responsive. Same thing with the “Fog Settings” tab. Give that a try. Certainly worked for me for the moment.

Hi,
dev-branch 1.5.10.1754 was OK.
dev-branch and stable 1.5.10.1798 is not OK.

Running on Debian VM 13.4 in Proxmox.
Everything is OK until I click “Hosts” . PHP-FPM starts eating taking 100% of CPU for minutes but gives no errors in apache2 or php8.4-fpm logs.
Other listings and dashboard are OK. Report/Pending Mac List is slow too.

Approve All Pending MACs for All Hosts returned the speed of server back to normal. Thanks @rogalskij!

Host IDs are showed in front of names like this: (271) - DELL-AT-WORK

Installed PlugIns
accesscontrol
persistentgroups
site
tasktypeedit

I have got a plenty of these warnings but it is problem of old plugin, I suppose:
