NetXMS Support Forum

Hi!

Hm ok, strange.
But it works now, so maybe it was just the good ol' user error

Thanks for your help though!

Best regards,
Dan

Hi!

The plaza variable is created like this,


if ($node->name ~= "^(.*)ru[rf]([0-9]{2})1") {
plaza = $1;
lane = int64($2);
}


I just tried changing the creation of the variable "server_name" from,


server_name = "" . plaza . ".se";


to,


server_name = plaza . ".se";


And now the following creates a node object,


server_name_node = FindNodeObject($node, server_name);


It does work now, it seems like it was my creation of the variable "server_name" that was the problem.
So I guess it was my bad code that just didn't work

Thank you for the feedback!

But, now when I test the script the console application dies

Hi!

I am using 1.0.1.

I found the following post very helpful,

Quote from: Victor Kirhenshtein on February 25, 2010, 06:40:53 PM
In 1.0.0-rc1 I have added new NXSL function FindNodeObject. It takes two arguments: current node object and ID or name of node of interest. It can be used as following:

Code Select Expand


sub main()
{
   // Search for node named "gateway"
   gw_node = FindNodeObject($node, "gateway");
   
   if (gw_node == null)
      return 0;   // No such node or access denied

   // from here, gw_node can be used in a same way as $node, for example:
   status = GetDCIValue(gw_node, FindDCIByDescription(gw_node, "Status"));

   return 1;
}


I have tried doing this with the following code,

server_name = "" . plaza . ".se"; // this gives me the server name in the var, as this is different depending on which node that the DCI is running on
server_name_node = FindNodeObject($node, server_name);
return server_name_node;

This only gives me "null" which would indicate that the server with the server_name is non-existant.
But I have also set the node name manually, instead of using the var, which works as it should, but this means a lot of manual work and a generated name in a var is much more flexible

So my question is, is there something I am missing, or is it just not possible to use the variable instead of a static argument?

Best regards,
Dan

It was the push DCI that was my main concern, sorry for not saying so!

This will probably solve the problem perfectly

Thanks!

Dan

Hi!

I am trying to monitor if a DCI is not updated within a certain interval, like a heartbeat.
If the "monitored" DCI is not updated within a scheduled interval, then it should create the alarm.

I am thinking about using the data collection transformation for this, but I don't know if there is any built in function or any other way to check the date for the last update on a DCI?

Is this the way to go or is there a better way to create such a heartbeat monitoring?

Keep up the great work!

Best regards,
Dan

Hi,

We are, at the moment, using two installations to monitor two different locations.
The largest installation contains about 1000 nodes and the smaller one about 200 - 300.

We are planning to add about 1 - 2 more locations in the near future and gather all the alams in a central server for easier management.

Ah nice.
Thanks for the very fast help and answers!

Best regards,
Dan

Here it is, this time when I created a few groups,

Will do,

I have recompiled the server though and it seems like I am able to remove groups without any problem.
But I will run it in gdb and send a trace.

Best regards,
Dan

Checked the eventlog and noticed the following entry when trying to remove one of the groups:

"Database query failed [Query: DELETE FROM groups WHERE id =-2147483643; Error: ERROR: relation "groups" does not exist]

Which is correct as there is no such table.

It seems like that error causes netxmsd to crash.

Located in src/server/core/userdb_objects.cpp on row 651,
_sntprintf(query, 256, _T("DELETE FROM groups WHERE id=%d"), m_id);

Hi,
Im running 0.2.30 under ubuntu intrepid.
Netxms where running fine during configuration until I tried to configure new users and groups, like adding new access, removing access, adding users to groups, as well as deleting some of them.
This happens when running it both as a daemon and in the foreground,

netxmsd  -c /etc/netxms/netxmsd.conf

When I restart netxms and connect again, the deleted and altered groups/users are still there.

I am able to add nodes and change other things without any hazard.

I am running it with PostgreSQL 8.3.8

I have attached an strace of a crash.

Anyone got an idea what could be wrong?

Hi!
Ah, I thought I was losing it

Thanks for the answer, and a truly great work!

Hi guys!

I'm running 0.2.26 and trying to add a new user, which is not an administrator, to only to view maps and alarms, but this user should also be able to acknowledge and also terminate alarms.

I am able to acknowledge and terminate alarms, and I can see all the current alarms in the alarm browser, but when I try to view my newly created map "overview", I can only view the "default" one.
My own map, "overview" is created with a "container" as a root object.

I've added a user, alarmoperator, under the group "Operator" which has the default properties,
- view snmp trap log
- view event database
- delete alarms

My user does not have any other system rights.

I have added the group "Operator" to have the following rights and properties on both the objects "Entire network" and "All services",
- Read
- View alarms
- Acknowledge alarms
- Terminate alarms

My containers under "all services" are set to inherit the rights from parent container.

My question is, how do I add the new map so my new user can view it?
I am able to view the map as the administrator, but not as a "regular" view only user.

Couldn't find anything regarding this in the user manual.
Hopefully someone knows what I am doing wrong!

Thanks in advance

Best regards,
Dan
