Unable to perform Discovery

[sahaQaa]

Hello,
For some reasons im unable to start Discovery proccess. I create simple Discovey rule, but then i dont receive any data in "Monitoring" --> " Discovery" tab. I tried to cahnge ammount of "StartDiscoverers" value, and also played with MySQL values to force Discovery:

> use zabbix;
> select * from drules;
>update drules set nextcheck=unix_timestamp(now())+30 where druleid=2;

and like this:

> update drules set nextcheck=1588260000 where druleid=4;

But it didnt worked for me.

Is anything else i could do to make Discovery work?

Update: Upgraded Zabbix server to 4.4 --> Discovery still not working. Any ideas? :-)

Hi!

Try to rise your DebugLevel in your zabbix server config. At 4th level you can see the discovery messages.

Thanks for reply :-)
Actually it was because of my neglect of RTFM :-)
I found YouTube video with example of Network Discovery, and now everything is working as expected :-D
