Monitor Settings Reset

[saad]

Dear Team,

We are facing a issue where Monitor settings reset at specific time i.e 00:59:01 every day, the only error that we can see in debug log is
================================
11/09/18 00:58:59.234801 zmc_m79[58696].ERR-zm_remote_camera_rtsp.cpp/322 [Error while decoding frame 0]

====================================
and it keeps on repeating after some interval

The settings set as
Source Type : Ffmpeg
Target colorspace : 24 bit color
Capture Width (pixels) : 1280
Capture Height (pixels) : 720
Event Prefix : Recording
Section length : 3600
FPS Report Interval : 1000
======================================
and the settings reset to
Source Type : Local
Target colorspace : 8 bit color
Capture Width (pixels) :
Capture Height (pixels) :
Event Prefix : Event-
Section length : 600
FPS Report Interval : 250


This process happen to 5 monitors out of total 9. We have no any cron job that is causing this behaviour

Do you have any filters set to delete events? Check resources allocated to your database server especially innodb_buffer_pool_size

I can't think of anything in ZM that would do that. I would take a close look at mysql error logs.

@bbunge,
Yes we have a background filter, set to delete the events that is more than 3 days old, and innodb_buffer_pool_size is 134217728
@iconnor
I tried to check mysql error logs but no luck , how can I check on exact time and how to convert TimeKey(1541559494.466080) to actual time?

New findings,
- My other 4 monitors remain save as we have set their disable time events from 23 to 09 and in our disable scenario we set monitor "source type" to "Local"

- If I set one of my affected monitor to disable from 00 to 01 then its monitor settings reset at 01:59:01

- So this reset monitor issue occur only if "Source Type" is set to "Remote" Or "Ffmpeg" and at specific span of time at night

Dear Fellows,

I have found that the issue was in our script that is disabling the monitor for specific time. Thanks for your time.
