Hi all!

- Original event name passed to alarm timeout event as 5th parameter
- Added information tooltips in switch port view
- Improved performance of active network discovery
- Minimum, maximum, and moving average for ICMP response time in ping subagent
- Fixed issues:
        NX-1463 (Web UI does not work under Tomcat 9)
        NX-1475 (Deselected "Create helpdesk ticket on alarm creation" is not being saved in EPP)
        NX-1486 (NXSL function CreateDCI should allow creation with default retention and poll intervals)
        NX-1489 (Unreliable MariaDB Connector/C version detection in workaround for MariaDB bug CONC-281)
        NX-1494 (Release 2.2.8 failed to compile on macOS)
        NX-1496 (Add agent parameters System.Memory.Physical.Available and System.Memory.Physical.AvailablePerc on FreeBSD)
        NX-1501 (In test mode $dci variable is not set)

Hi,

what Java version you are using? Desktop client may not be compatible with Java 10 and higher.

Hi,

you can create script DCI with the following script:


// Read default gateway from DCI
gw = GetDCIValueByName($node, ".1.3.6.1.2.1.4.21.1.7.0.0.0.0");
if (gw == null)
return null;

// Find node which will be ping source
pingSourceNode = FindNodeObject($node, "netxms");
if (pingSourceNode == null)
return null;

// Return ping RTT from ping source node
return AgentReadParameter(pingSourceNode, "ICMP.Ping(" . gw . ")");


This script reads default gateway address from existing DCI and then use agent parameter ICMP.Ping to ping it from another node. Name of ping source node should be set in FindNodeObject function call.

Hi,

just sent upload link in PM.

So rest of connections were not discovered. I see that all discovered connections were discovered using spanning tree information. This is less reliable method and used by server as last resort. Is it possible to turn on LLDP or CDP on your switches? It will greatly improve discovery accuracy. If not possible, make sure that you have spanning tree protocol enabled on all switches.

Seems that they are not published. However, you can find javadoc archives in Maven Central: http://central.maven.org/maven2/org/netxms/netxms-client/2.2.6/netxms-client-2.2.6-javadoc.jar

Hi,

I cannot reproduce this issue. Could be packaging error. How do you run nxshell and what package you are using?

Hi,

those methods was renamed in 3.0. For 2.2 branch, use syncEventTemplates, getCachedEventTemplates and findEventTemplateByCode.

Best regards,
Victor

Hi,

it is deprecated in 3.0 branch (latest javadoc generated from 3.0), you can safely use it in 2.2 branch. In 3.0 you should call DataCollectionConfiguration.modifyObject with data collection object ID set to 0 (but this will not work in 2.2).

Hi,

getScriptLibrary() call intended to retrieve list of available scripts (because script source could be quite big). Source code for each script should be retrieved individually using getScript() method. The following script will show sources for all scripts:


scripts = session.getScriptLibrary()
for script in scripts:
    script = session.getScript(script.getId())
    print('id={0} name={1} source={2}'.format(
             script.getId()
            ,script.getName()
            ,script.getSource()
        )
    )

Hi,

can you share exact errors you have? What database driver you are using?

Best regards,
Victor

Can you please reproduce timeout issue again, with server running at debug level 7 and agent at debug level 6, and send me synchronized log files for period during synchronization?

Best regards,
Victor

It looks that from time to time database cannot cope with incoming data rate and so writer queue grows. You may need to fine tune your database server. But it seems to happen on few occasions so it should not be a root cause for data synchronization timeouts.

Hi,

please check object ID for MAINCR_GSX (you can find it on overview tab), then run the following command on NetXMS server command line:

nxadm -c "show topology <id>"

(replace <id> with actual node ID) and post it's output.

Best regards,
Victor

Hi,

what is your idata writer queue size? You can check it in server debug console with command "show queue". If you have historical graph for idata queue please also share it.
Also, how many DCIs you have? You can check it in server debug console with command "show stats".

Best regards,
Victor
