NetXMS Forum

Thank you for your help.

Kindest regards.

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.

This issue has been solved by installing the pre-release of the next version.
NetXMS servers have been running for more than a week without any form of crashing.

Thanks Victor and others for your support with this matter.

Unfortunately the configuration mentioned in my last post (Statuspollerinterval 600, DefaultDCIPollingInterval 600, ConditionPollingInterval 600) did not last.

Server just logged the error "Thread "Item Poller" does not respond to watchdog thread" and does not poll new values anymore and displays empty graphs again.

FYI
For one location i configured the following settings on a NetXMS server:

Statuspollerinterval          600
DefaultDCIPollingInterval  600
ConditionPollingInterval    600

Although there are unrealistic values for daily operations the server has been running for more than one day now without crashing.

Still crashing.

Added some screenshots in this reply post of situation after the issue has occurred.

This issue has not been solved.

Have done some new troubleshooting.

-MySQL logging enabled and reviewed logging.
Maybe someone can tell me what to look for besides the usual error search.

-Changed some server configuration parameters, for example in one troubleshooting 'run':  increased the StatusPollingInterval from 60 seconds to 300 seconds.
and in another troubleshooting 'run' : increased PollerThreadPoolMaxSize from 250 to 500, PollerThreadPoolBaseSize from 10 to 20 and NumberOfDataCollectors from 25 to 50.

Unfortunately until now the server keeps on 'crashing' daily.

Hope there is a solution for solving this issue.

Different location. Different network. Different NetXMS server, (software new version 2.0.2)

same issue : daily server crash - Thread "Item Poller" does not respond to watchdog thread, empty graphs, no polling values

created DUMP file and log files. Attached in this reply.

Hope you can find some leads within the new information regarding this issue.

Replaced the mssql.ddr file with the new mssql.ddr file, provided by you.

NetXMS Core service starting and running OK now.

It seems that the issue has been resolved.
Thank you for your help.

Yesterday i successfully upgraded to 2.0.2 at around 14:00h.

Unfortunately this issue, "daily server crash - Thread "Item Poller" does not respond to watchdog thread", occurred again 5 hours after the successful upgrade to version 2.0.2.

* application and services still running, but no dci polling values
* Error viewing last values for each node, screenshot attached in this post.
* empty dashboard graphs

Any advice in fixing  this issue is more than welcome.

Solved this issue by :

• removing all NetXMS installations (but keep the already existing MySQL database)
• moving the whole (content of)  C:\NetXMS folder to an .old folder
• installing netxms-2.0.2-x64.exe to a new folder c:\NetXMS
  <no errors occurred>
• running c:\NetXMS\nxdbmgr -upgrade

Everything working OK now in new NetXMS version 2.0.2 with the existing database.

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
