Discovery issue

[olidel]

Hello,

I have an issue with the discovery process and I cannot pinpont where this is coming from. Basically the discovery process is sending me e-mail about host or service that no longer exists on the network Eg I am receiving this e-mail:

Discovery rule: Local network 2

Device IP:192.168.198.44
Device DNS:
Device status: UP
Device uptime: 233d 20h 9m

Device service name: SSH
Device service port: 22
Device service status: DOWN
Device service uptime: 275d 12h 47m


Another example:

Discovery rule: Local network 2

Device IP:192.168.198.39
Device DNS:
Device status: DOWN
Device uptime: 281d 19h 6m

Device service name: ICMP ping
Device service port: 0
Device service status: DOWN
Device service uptime: 281d 19h 6m

In the Zabbix GUI there is nowhere that I can see the ip address "192.168.198.39". Of course, I'm seeing "192.168.198.44" but this is OK for that one. In the discovery rule "Local network 2", I have even restricted the ip discovery range from 192.168.198.3-62 to 192.168.198.4-62 but I still see some message about the IP 192.168.198.3. I have restarted multiple time the zabbix server and evn the server itself to be sure that the configuration files are read properly but without succes. Do you have an idea where I should look for this ghost information?


Thaank you.

Why you need to do this with a discovery rule?

Hello,

Thank you for your reply. I do not really understand your remark. Is there other way to do it? I want to find out automatically about new host (or new services) on some particular subnets. Anyway, this does not explain why I'am receiving some e-mails for non existent host. Also it is worth noting that I have also disabled in the action menu the "send e-mail" option but I'am still receiving e-mails.

Are you sure it is the same database configured in frontend (zabbix.conf.php) and server (zabbix_server.conf)?

Hello,

/usr/share/zabbix/conf/zabbix.conf.php:

// Zabbix GUI configuration file.
global $DB;

$DB['TYPE']     = 'MYSQL';
$DB['SERVER']   = 'localhost';
$DB['PORT']     = '0';
$DB['DATABASE'] = 'zabbix';
$DB['USER']     = 'zabbix';

:/etc/zabbix/zabbix_server.conf:

### Option: DBHost
# Database host name.
# If set to localhost, socket is used for MySQL.
# If set to empty string, socket is used for PostgreSQL.
#
# Mandatory: no
# Default:
DBHost=localhost


### Option: DBName
# Database name.
# For SQLite3 path to database file must be provided. DBUser and DBPasswo$
#
# Mandatory: yes
# Default:
# DBName=

DBName=zabbix


### Option: DBUser
# Database user. Ignored for SQLite.
#
# Mandatory: no
# Default:
# DBUser=

DBUser=zabbix

When I have installed this the first time a few year ago, I have used the installation wizard, so I don't think that it was possible to choose a different database.

Thank you.

Hello,

Sorry for the delay but this is what I have. Please note that in the action -> Operations, there is no "send e-mail". Although I'am still receiving emails.










Thank you.
