Script looks correct. Could it be that disk E: has non-zero total space (could be the case if this is CD drive with disk inserted or any other read-only device)?

Судя по сообщениям об ошибке (ПРЕДУПРЕЖДЕНИЕ:  нехватка разделяемой памяти), проблема в настройках PostgreSQL сервера. Увеличте размер shared memory, должно помочь.

Hi,

!= null should work. Can you show full script please?

Hi!

Actually, if node is compoletely down, and SYS_NODE_DOWN event is generated, all SYS_IF_DOWN and SYS_SERVICE_DOWN events should be correlated to SYS_NODE_DOWN and not cause message sending. However, if node is not down completely, you may get lot of events and notifications if multiple interfaces goes down for example. The only way to create digest messaging is to write your own script which will do that. For example, you may store event messages into text file in event processing policy (using "execute" type action) and run cron job every 5 minutes to send this file as email if it is not empty.

Can you please show how exactly problematic threshold looks like?

Hi!

It's definitely a bug - looks like threshold state was not saved across restarts, although it had to be. I'll check this.

Currently you cannot see what output agent was gathered nor measure response time. Feel free to fill feature request

Yes, that change already applied - so after upgrade to 1.2.14 you'll get this problem fixed as well.

Hi!

Could you check what is returned by underlying SQL query? Implementation of this function tries to parse value read from database as double, so there should be no limitation on 32bit integer size.

Actual query is

SELECT avg(coalesce(idata_value,0)) FROM idata_<node_id_here> WHERE item_id=<dci_id_here> AND (idata_timestamp BETWEEN <time1> AND <time2>);

Hi!

Currently we do not support configuration synchronization between two NetXMS servers (although we have this in roadmap). What is possible now is event forwarding from one NetXMS server to another.

Hi!

If topology information is correct, you can try to use this script: http://wiki.netxms.org/wiki/Script_Example:_Additional_Information_About_Connected_Node as an example of how to get connected nodes and for SYS_NODE_DOWN event check if node is connected to the switch which is already down.

NetXMS agent uses PDH API to access performance counters. You can add feature request to our bug tracker for instance discovery support for perf counter DCIs.

Best regards,
Victor

Hi!

You can create filtering script for instance discovery which will attempt to get total space for file system and only return true if data was read successfully and size is non-zero. It could be something like this:


value = AgentReadParameter($node, "FileSystem.Total(" . $1 . ")");
return (value != null) && (value > 0);

Hi!

WMI (stands for Windows Management Instrumentation) is not Windows Performance Counters - it's two different things. First you should understand what exactly you want to use. From the name \PhysicalDisk({instance})\Disk Reads/sec I suppose you are trying to use Windows Performance Counters. In this case, instance discovery will not work because DCI origin is not agent. It could be a feature request, but currently it's not possible.
