I know how to configure the number of polls needed for an activation event in THRESHOLD configuration. This is the 'samples' field.


Can this also be done for the number of polls needed for a deactivation event in THRESHOLD configuration.


At the moment when i have a look at the logging values of  a DCI with a threshold set i can see that a deactivation event already occurs after 1 poll with a value below the set threshold.
I would like to set the number of polls needed for a deactivation event  (rearm-event) to for example 5.

Anyone any suggestions?
Thanks in advance.

On a test server i am upgrading from 2.0 RC2 to 2.0.2.
At the end of the 2.0.2 installation an error occurs : "service named netxmscore already exist" -->see attached screenshot


Server OS : Windows 2008 Server R2 SP1
Database : MySQL


Followed upgrade instructions as below ( NetXMS Server Installation Guide ):
1. Download the latest version from https://www.netxms.org/download, if you don't have it. You will need Windows installer (named netxms-VERSION.exe, for example netxms-1.2.15.exe).
2. Stop NetXMS server.
3. Check database for possible inconsistencies:
C:\NetXMS\bin> nxdbmgr check
Proceed to the next step only if database checker does not report any errors!
4. Run NetXMS installer and follow the prompts. Normally, you will not need to change any settings on installation wizard windows.


Any suggestions for resolving this issue?
Thanks in advance.

Kind regards,
Markus

Situation:
In a test environment i run NetXMS version 2.0RC2.

netxmsd: sh sta
Total number of objects:     489
Number of monitored nodes:   68
Number of collectable DCIs:  272

4 dashboards have been configured and are up and running. During most of the day everything is working properly. DCI values are polled and displayed nicely.

Issue:
On an average of once a day the server seems to crash. In the Windows event viewer the error : Thread "Item Poller" does not respond to watchdog thread.

From that moment the dashboards are empty and show an error message. At the same time when I execute 'last values' an error message is shown and no values can be displayed. See attached screenshots.

When i view the Windows services it appears that netxms core service is still running. But when troubleshooting this issue the only solution to temporarily solve the issue is stopping and starting the NetXMS core service. Eventually resulting with no history in the dashboard graphs.


Any suggestions in fully solving this issue?

Thanks in advance.
Kindest regards.

Before upgrading on the operational network i first upgraded my testmachine with NetXMS 2.0 to the newest release NetXMS 2.0.2

Since then I am not able to logon again to the NetXMS Console. -->error message : connection refused

On the test machine the NetXMS database runs on a SQL Server 2012 (SQLEXPRESS) instance.

troubleshooting until now :

-ran command line : nxdbmgr upgrade
this reported a successful upgrade
new login attempt -->connection still refused

-ran command line : nxdbmgr check
this reported a database lock, and removed the lock
new login attempt -->connection still refused

-ran command line : nxdbmgr resetadmin
this reported a successful reset of the admin account to the default password "netxms"
new login attempt with default admin credentials-->connection still refused


Before i upgrade the live operation to 2.0.2 i want to sort out this issue.
So hereby a request for help.
Any suggestions?

Kindest regards,
Mark
