Discovery rule / wrong nextcheck

[alejodurin]

Hi all.

I have implemented a discovery rule to apply automatic registration, and I have a problem.
The discovery isn't run in the interval that I have established.
I set the interval to 1 hour (I also tried 120s) but for some reason the "Discovery" does not run.

I went to the database and consulted the rules discovery table and discover that doesn't matter if I change the update interval, the "nextcheck" to run the discovery is always 1969-12-31, never change; so the discovery never will run.

This is my configuration of my discovery rule.

Name: Local Network
Discover by proxy: No proxy
IP range: 192.168.0.0/16
Update Interval: 1h
Check: Zabbix agent "system.uname"
Device uniqueness criteria: IP Address

When I consult the database , this is what I get.

mysql> select name, from_unixtime(nextcheck) from drules;
+------------------------+--------------------------+
| name                   | from_unixtime(nextcheck) |

I have the same issue for an SNMPv3 Discovery agent.

MariaDB [zabbix]> select * from drules;
+---------+--------------+---------------+-----------------+-------+------------+--------+
| druleid | proxy_hostid | name          | iprange         | delay | nextcheck  | status |
+---------+--------------+---------------+-----------------+-------+------------+--------+

|       3 |         NULL | SNMPv3        | 192.168.1.1-254 | 1h    |          0 |      0 |

Did you ever find a resolution?
