Good afternoon. Help please understand. There is Zabbix v2.08

I got my hands on duty tuned zabbix from another administrator. I have it cleaned and put in order. Everything works, but I can see the agent logs a permanent record - can not send list of active checks to [1.2.3.4]: host [superhost] not found.

In the setting of an agent on the server zabbix no such mention. Just do not understand the situation. 1.2.3.4 (testhost) is not superhost, a superhost is 1.2.3.10

Help please understand

Lines like "cannot send list of active checks to ..." are not logged by the agent - they are logged by the server when it receives a request for a list of active checks from an agent. In these requests, the agent specifies its hostname ("Hostname" parameter in the configuration file). If the server cannot find such a host in its database, it logs this error message.

So you should check the "Hostname" parameter in agent configuration file and verify that there exists a host with this name in server's database.

  • I am getting the error on the client: `no active checks on server [:10051]: host [] not found` – kev Sep 26 '17 at 03:08
  • @kev, as the error message says, please verify that the hostname in the agent configuration file matches a hostname in the frontend exactly. – asaveljevs Sep 26 '17 at 06:41
  • I am using Auto registration to submit the hostname to the server. Is it possible, that the client talks to the server before the server actually know who it is talking to? – kev Sep 26 '17 at 06:43
  • We may be getting a bit off-topic here, but do you have auto-registration working correctly (https://www.zabbix.com/documentation/3.2/manual/discovery/auto_registration)? Do you have a corresponding action defined and do you have new hosts created automatically? – asaveljevs Sep 26 '17 at 11:05
