Looks like result of database corruption. If I remember correctly lost_interface_#### objects was created in some older versions after errors. Current version should not create them. As they likely had unreachable IP addresses, status poll just take longer due to timeouts.

Hi,

seems that metadata is incorrect for some reason. Try to stop server and execute the following query:


UPDATE metadata SET var_value='CREATE TABLE tdata_records_%d (record_id number(20) not null,row_id number(20) not null,instance varchar(255) null,PRIMARY KEY(row_id),FOREIGN KEY (record_id) REFERENCES tdata_%d(record_id) ON DELETE CASCADE)' WHERE var_name='TDataTableCreationCommand_1';


then drop table(s) having ORA-00001 errors and run nxdbmgr check again (it should re-create all missing tables correctly).

Hi,

most likely you already have (presumably incorrect) subnet object for /24. You can check what's inside and delete subnet object (make sure that nodes inside it bound to at least one container, then they will not be deleted with the subnet), then do configuration poll on a node - it should create correct /26 subnet object.
Also, in 2.0 we do some fixes to subnet creation and binding logic, it will help in such situations.

Про world map - согласен, и сделать это по идее не сложно. Добавил в трекер (https://dev.raden.solutions/issues/777).

Про базы не совсем понял - какие именно базы и как их объединять?

Сейчас можно настроить что-то похожее. Для любой ноды можно создать internal DCI PingTime. Соответственно в Last Values будет время отклика на ping во время последнего status poll. Затем можно настроить DCI Summary Table по этому параметру и видеть в виде таблицы времена отклика для узлов.

Do you have WAR products feature (org.eclipse.libra.warproducts.feature.feature.group) installed? If yes, what version? I use 0.3.1.

Hi,

O_RDONLY means that agent wants read only access to the file. Sharing mode is controlled by third argument, which is set to _SH_DENYNO, meaning that agent allows both read and write shared access to the file. However, the problem may be with the application writing to the file - if application requests exclusive access (i.e. not permitting read access by others), it will not be able to open file for writing. We cannot do anything about it. If you can control the application in question you can change it or request application developers to allow shared read access to the log.

Hi,

we are gradually implementing IPv6 support under the hood. Management console and agents can communicate over IPv6 already, and there are internal changes to support both IPv4 and IPv6 addresses on objects. Final 2.0 release will fully support IPv6, and you will see IPv6 subnets in M3 or M4.

Hi,

no, currently it's not possible. Implementing such feature within NetXMS itself can be quite complicated because we will need to implement in-memory graph creation on server side (currently all visualization done on client side).

Poll count 300 means 5 hours to change status - is it what you intend?

I've added session agent termination to  agent installer. The only problem is that session agent will be unavailable until restart because installer will not be able to start it again in another user session.

If those nodes respond to ICMP ping, you can try to configure active discovery for problematic networks. Also, NetXMS will not add non-responding nodes - are they accessible from NetXMS server?

Hi,

please send me output of query

SELECT * FROM metadata

from your database. For now, try to answer y only to invalid object fix - that way it will fix at least this problem.

Hi,

you can change required poll count for node interfaces. For example, if you set it to 5, server will consider interface as down if 5 consecutive polls will report that. Node will not be marked as down as long as interfaces not marked as down.

В багтрекере лучше все писать по английски.

Вытянуть кусок файла в DCI - только через ExternalParameter (еще можно написать скрипт как ExternalParametersProvider если надо сразу много строк в виде параметров из файла вытащить).
