NetXMS Support Forum

Hello, Victor!

I've read in manual about centralized agent upgrade feature, but I cannot find any reference to how exactly it can be done?
Also, it would be very helpful if such features as Agent Packages and Agent Configurations were documented.

Hello, Victor!

I want to monitor disk queue on remote PC, I've wrote script in bash that returns disk queue, but it takes 5 minutes for this script to return a value ( i used command: iostat -xd /dev/sda 300 2). I've modifed time-out's in nxagentd.conf for server to wait. While it works server keeps asking agent to return a value, in the end i have a plenty of iostat processes running, and no value is returned to server. How can i configure agent/server to wait 5 minutes and take a value from the script?

Hello, Victor!

I have such question: If I already installed NetXMS server with agent on some PC, how do I install nxhhtpd there?
Should I do ./configure --with-server --with-agent --with-mysql --with-nxhttpd ot just ./configure --with-nxhhtpd ?
I tried them both - and in first case NetXMS doesn't work any more, and in second case web interface does not accept passwords.
May be I am doing something wrong.. How to correctly install nxhttpd on server with NetXMS server?

Hello, Victor!

I was trying to reinstall NetXMS server, and as I did I was trying to re-initialize database:
/usr/local/netxms/bin/nxdbmgr init /usr/local/netxms/share/netxms/sql/dbinit_mysql.sql
NetXMS Database Manager Version 0.2.20

Configuration file OK
Initializing database...
SQL query failed:
CREATE TABLE config
(
var_name varchar(63) not null,
var_value varchar(255) not null,
is_visible integer not null default 1,
need_server_restart integer not null default 0,
PRIMARY KEY(var_name)
)
Database initialization failed

Permissions for database schould be ok, because I defined in netxmsd.conf to connect as root.

Then I tried to initialize database manually, so I did: cat /usr/local/netxms/share/netxms/sql/dbinit_mysql.sql | mysql -u root -p
Tables were created, but then:

/usr/local/netxms/bin/netxmsd -D 9

I am using Mysql, during re-installation i dropped netxms database. I tried to install different versions of MySQL, and I tried to re-compile NetXMS server.

Hello, Victor.

How can I allow NetXMS agent to restart or shutdown remote nodes? When I look at agent supported actions in console it returns only agent.restart.

Hello, Victor!

I've successfully installed NetXMS server, and I'm trying to install web interface (nxhttpd) on the same PC.
The installation was successful, but when I try to login in web console is says: Unable to login (Access denied).
I am sure that I use the correct username and password, I even tried to add some users in NetXMS console and to login as a new user, but still - Access Denied. I've reproduced this problem twice, and interesting that if I install nxhttpd on another PC, and configure it to connect to my NetXMS server - everything is fine. Here is log of nxhttpd:

Configuration file OK

How can I get into web console?

Hello, Victor!
I am trying to compile netxms 0.2.20 witch odbc support. during compilation the system says:
odbc.cpp: In function 'void* DrvSelect(ODBCDRV_CONN*, WCHAR*, DWORD*)':
odbc.cpp:250: error: cannot convert 'const WCHAR*' to 'const wchar_t*' for argument '1' to 'wchar_t* wcsdup(const wchar_t*)'
odbc.cpp: In function 'LONG DrvGetFieldLength(ODBCDRV_QUERY_RESULT*, int, int)':
odbc.cpp:284: error: cannot convert 'WCHAR*' to 'const wchar_t*' for argument '1' to 'size_t wcslen(const wchar_t*)'
odbc.cpp: In function 'WCHAR* DrvGetField(ODBCDRV_QUERY_RESULT*, int, int, WCHAR*, int)':
odbc.cpp:304: error: cannot convert 'WCHAR*' to 'wchar_t*' for argument '1' to 'wchar_t* wcsncpy(wchar_t*, const wchar_t*, size_t)'
make[5]: *** [odbc.lo] Error 1
What can be the cause of this?

Interesting that netxms 0.2.19 compiles without problems.
