NetXMS Support Forum

Добрый день!

Если я правильно понимаю этот скрипт, при остановке сначала останавливается база данных, а уже потом netxmsd. Соответственно при выходе сервер может не записать какие-то данные из памяти, поскольку база уже остановлена. Правильная последовательность - дать SIGTERM процессу netxmsd, дождаться его завершения (в зависимости от ситуации это может занять какое-то время - до 30 секунд на больших базах), и только после этого останавливать базу.

Hi!

If you are connecting to localhost, you should grabt access to database in this way:

GRANT ALL ON netxms.* TO netxms@localhost IDENTIFIED BY 'PaSsWd';

Because MySQL threats localhost connections differently. (MySQL page where this behavior is explained: http://dev.mysql.com/doc/refman/5.1/en/adding-users.html).

Hi!

Currently, --enable-unstable only enables ODBCQUERY subagent. If you ever need it, you will have to install UNIXODBC first, and then it should compile as well.

Hi!

1.Is there a better way for monitoring the 2 way connection between the NetXMS servers?

One possible alternative is to check remote port 4701 via portcheck subagent.

2.Is there performance issue if events (logging unchecked) are generated on short interval (i.e. 5 sec)?

Should not be. Event processing is usually very fast. Btw, it is one of the reasons why direct data collection not allowed in event processing policy's scripts.

3.What is the code in NXSL to access the last DCI?

What you mean by "last DCI"?

4.What is the code to access the last DCI collected timestamp?

It's not possible in 0.2.31. However, I have added new function GetDCIObject which returns reference to object containing all DCI's attributes, including last poll timestamp.

5.In DCI Transformation, using NXSL, can we use other other DCI value and based on both to return value (i.e. true or false), which to be used in the thresholds (to generate event).

Yes, you can access other DCIs values via FindDCIByName, FindDCIByDescription, and GetDCIValue functions. If you creating computed DCI, sometimes it can be useful to use Internal Dummy parameter as a source and read values of all relevant DCIs in transformation script.

P.S. Example of calculated DCI: https://www.netxms.org/forum/index.php/topic,289.0.html

You should pass device number you have specified in Device= parameter. For exasmple, if you have

Device = 0:ANY:USB

in your config, then you should use for example UPS.SerialNumber(0).
Could you please post your agent's config? Also, try to tun agent in debug mode (with -D switch) and see if there area additional UPS-related messages.

Hello!

How do you run ./configure? odbcsapi.cpp is a part of odbcquery subagent, which compiles only if --enable-unstable is set. Try to run configure without that switch.

No, the only requirement is that agent should be reachable by IP. Try to run remote agent in debug mode (nxagentd -D) to see if connections comes to agent. Don't forget that if NetXMS server is multihomed or there are NAT between server and agent, you may need to specify different IP address under MasterServers in agent's configuration file.

Yes, it's libnxsms_nxagent.so on Linux and nxagent.sms on Windows.

1. Только при помощи дополнительных внешних скриптов.
2. нет
3. нет
4. это возможно - выбираем шаблон, делаем unbind, выбираем ноду, которую хотим убрать. После этого система спросит, что делать с DCI, созданными через шаблон - удалить или отвязать от шаблона.

При следующем зависании сервиса, попробуйте пожалуйста подключится к сервису командой nxadm -i, дайте команду dump, и пришлите получившийся дамп на [email protected] - попробуем разобраться.

Так вообще-то не должно быть. А какой тип данных стоит у DCI? Должен быть unsigned integer - тогда он будет правильно обрабатывать значения, боль шие чем 2 в степени 31, и переходы счетчика через 0.

Hi!

Because your application written in Java, in process list you will see only a bunch of Java VM processes. If you don't have some API to determine if your application is still running, I see the only way is to determine full command line for each of your applications, and if they are differs, then you are lucky and can monitor if each application is running by using Process.CountEx parameters.

Hello!

You should configure nxagent.sms as your SMS driver on server, and as SMSDrvConfig, set IP address of NetXMS agent where phone is attached.
On agent, you should load sms.nsm subagent, and set port for phone communication via Device parameter in SMS section. For example, for phone connected on COM1:


# main section here
SubAgent = sms.nsm

*SMS
Device = COM1:

Yes, but only on Windows. To add USB UPS, use the following syntax:

Device = 1:ANY:USB

if you have only one USB UPS attached, and

Device = 1:<UPS serial number here>:USB

if you have multiple USB devices.

You have to edit conf files if you wish to execute commands remotely via NetXMS agent. In that case you should add appropriate Action entries in agent configuration files.

Victor

Hello!

To run command on management server itself, you don't need to change server's configuration file. You just need to specify your executable under "Command". If you wish to run .bat or .cmd file, you may need to use form of

cmd.exe /C <your_cmd>

Executable can be located anywhere, but if it is not in system PATH, you should add full path to it when defining action.
