This worked!

Many thanks!

I figured out that agent in daemon mode reacts with pain on sudo command in external script.
E.g. if script contain something

#!/bin/bash
echo 300

Than it works, but if we add sudo

sudo -u someuser echo 300

It does not. Did anyone run into this?

Hi All,

I'm using external parameters in nxagentd.conf file, one of them:

ExternalParameter = CF2PRIVATEMEM:privatemem.sh

If I launch nxagentd -f -D 9  it executes and reads the parameter correctly

Which is wrong. Current version of server and agent is 2.0.5 and it does not work here.
When I had version 1.2.17 it worked correctly.

Hello Victor,

Yes, you were correct I have removed nxmc directory under "/usr/share/tomcat6/work/Catalina/localhost" which is default for tomcat installation on RHEL. And this worked.

BR,
Roman

Solved it :).

I usually rename nxmc-v.v.v.war to nxmc.war, so users can use the same URL like http://<IP>:8080/nxmc. And it didn't work with 1.2.7 version, if I live nxmc-1.2.7.war name everything works fine.

Hello Victor,

I've got trouble with new WEB GUI in 1.2.7. It displays an empty strings for the object tree, at the same time windows x86 client works fine. I've enclosed the screenshot of this.

Environment:
[root@netxms webapps]# cat /etc/redhat-release
CentOS release 6.2 (Final)
[root@netxms webapps]# rpm -qa | grep tomcat
tomcat6-lib-6.0.24-45.el6.noarch
tomcat6-servlet-2.5-api-6.0.24-45.el6.noarch
tomcat6-el-2.1-api-6.0.24-45.el6.noarch
tomcat6-6.0.24-45.el6.noarch
apache-tomcat-apis-0.1-1.el6.noarch
tomcat6-jsp-2.1-api-6.0.24-45.el6.noarch
[root@netxms webapps]#

Hi Victor,

The thing is that participants of this group can see and use everything under "objects" and nothing under "graphs" by default. (I have per group rights assigned on entities under "objects" and under "graphs" as well.) This is confusing, why not to have everything available to it.

Best regards,
Roman Davydchenko

Hello Victor,

This workaround works, many thanks for that!
I'll try web interface today later.

Best regards,

I run in error when compiling netxms on centos 6.3.

Configure arguments "--with-server --with-pgsql --with-agent --with-snmp".

Yes, the predefined graphs tab (the one near the objects tab). He does not get any error, I see only "root" and nothing under it. If I add "admins" group to these graphs access rights, user will see the graphs. But the thing is I thought that "admins" group is like a predefined admin account that can view and alter anything. And in this case I have to define it for all objects, graphs, etc.

Best regards,
Roman

Hello Victor,

I ran in problem adding the second administrator. E.g. I create user and put him into admins group. And this user cannot view any graphs.
I using win32 console and netxms 1.2.2.

One thing I also would like to have is when you change alarm status to "Resolved" the alarm highlights should be removed from devices.

Hello Victor,

I have added SNMP string polling and it has the same effect as ODBC polling. Current polled value is good and stored are ruined.

Best regards,
Roman

Hello Victor,

Changing type to integer effectively solved the problem. All previously stored values are now displaying correctly. The one thing I don't understand is why did this happen?

Hello Victor,

I've managed to build and launch ODBC subagent tried it and got some issues. Current query returns right result, but those results stored previously die or something wrong happens to them. I have included the printscreens of management console showing this and screen of collection configuration.

Agent is configured with the following lines:
*ODBC
Query = SQL.MySQLQuery:mybase:SELECT COUNT(*) FROM USERS WHERE USERACTIVE = 1 AND USERDELETED = 0:60

Normally query should return 171 or something like this.

Hello Victor,

It is working now! It compiled in both cases with and without --with-all-static (I'm using without). The thing is it was trying to copy odbc.so to <netxms-install-dir>/odbc.ddr when I issued "make install". So I had to go to "src/agent" subdir and issue "make install" there, and everything installed fine.

This does not help, same error appears.

Problem solved when I deployed 1.2.2 agent package.

Hello Victor,

I've got a problem compiling Static Agent when enabling ODBC subagent.

./configure --with-static-agent --disable-encryption --with-static-subagents=ODBCQuery --without-sqlite --with-all-static

Static agent without ODBC subagent compiles fine and Not static agent with ODBC subagent also compiles fine.

Hi,

For the first question: you'll have to provide IP connectivity to you laptop from netxms server and open tcp port 4700. And you will need to change IP address setting int netxms console each time you get new IP on your laptop. If you connect your laptop to internet in another location you have to think about NAT/port forwarding or VPN solution.
As I see it does not worth effort to monitor node that constantly keeps changing IP address. 

For second question: You must provide IP connectivity from netxms server to domain network B and allow TCP port 4700 in direction of these hosts, just in case you have stateful firewall.
