Problem solved: (slackware64-current) State before and required intervention: mysql daemon failed to start, reporting database corruption. :( I assume failure in mysql database, and zoneminder database is without failure. At the end that proved as correct. 1. move zoneminder database /var/lib/mysql ...

On my bad luck I did not checked backup and lost it. :( I've preserved only folder /var/lib/mysql/zm and overwrote mysql database with fresh empty one. Think of a situation, where you have to move your existing zm database (folder /var/lib/mysql/zm ) to other machine with fresh installed mariadb and ...

Zoneminder version 1.35.5 mariadb-10.5.4 I have huge events database. At some time there were sudden power drop (UPS battery failed) and this resulted in mysql database corruption. Mysql failed to start with database corruption error. So I assumed the failed database is in a mysql table and hoped ...

Hi! Zoneminder -1.35.4 GIT 4. june 2020. Slackware64-current, ZM compiled/installed/configured by myself. All works excellent, except zmaudit.pl. Every ten minutes a log shows: 2020-06-13 16:32:27 zmdc 29132 ERR 'zmaudit.pl -c' exited abnormally, exit status 255 zmaudit.pl_exited.JPG I noticed this ...

Thank you kitkat!

So I'll observe systems with that in mind and act accordingly.

Regards..

For starters, I'm going to link to https://make-linux-fast-again.com Which currently has: noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off These are obviously some options you can pass to the Kernel (such as via Grub: https ...

I've found that the best performance is with Nodect, and external motion detection. There is a downside, however, that you have to setup the external motion detection. In this case, you'd have the 3MP stream, and then Nodect on it. Yes that's obvious , but the question was how to deal motion ...

Yes, had in mind too (as htop show), until i've got figures well over 4 (5+).
I'm sure, as that was observed on different systems not only on one.
Could it be overclocking or kernel dealing with CPU states and speed?

Hi BiloxiGeek! I've read your post a few days ago, so my late answer. I have exact same config as you expecting lower computer load. So your question finally encouraged me to test that. option 1. : 3MP stream, nodect linked to VGA stream modect. Alarms recorded: 3MP h264 camera passthrough, VGA ...

Hi! I propose a better alarm cause view on linked monitor: My main hi resolution camera stream recording is triggered by a linked low res. stream motion detection. Main stream monitor "nodect" is linked to low stream monitor in "modect" function. All alarm causes on main stream are "Linked", so this ...

I post here, as ZM documentation is pretty old. I had unsolved ffmpeg UDP stream smearing problem for more than two years, with zm-1.30.0 installed and working 800 days without a single touch! That was not so huge problem, as I set source to "remote", and there the video is clean. As recent ZM from ...

Thank you Rockedge!

Glad to help with malfunctions discovery, to improve this excellent product.

Best regards to all contribute to it!

Can somebody please explain status figures for load and DB - attached picture ZM_1.33.x_GIT-status.jpg 1. what the lightning sign mean 2. Load number? - CPU is i5-7200U, dual core, 4 threads - and what number would be for 100% CPU load (all cores & threads)? 3. DB:X/Y - what numbers X and Y reflect?

Thank you for a reply.

Pointing out, that state is changed, only display of status is wrong.
When selecting saved state the one did change (cameras functions changed according to saved state), only display status is always "running" for a different saved but running states.

In zm-1-30.0 the web console shows run state as is with saved text. For example: I saved states "live_view" and "away" as states, where cameras shows only current video without motion detection, and another where motion detection is active and saves events. The WEB console correctly show the above ...
