Tomcat 7 on which I am deploying war file is on same machine as NetXMS server

Got that part working. Any suggestions for template use case when i have different servers with different age value ? Or do i need to create them all manualy ? Most simplest thing would be to get just 1 folder thats also the oldes one and return its age, then it could be compared in threshhold with %{customAttribute:50}

Got it!!! Thanks Again

There's a couple of minor things that are causing issues here. NetworkMapLink expects IDs within map, not netxms object IDs, so there's a function to convert. And we need to explicitly specify that IDs of status-providing nodes are of type "Long". Here's an example of working script: from java.util import ArrayList from java.lang import Long amap = s.findObjectById(2722) mapPage = amap.createMapPage() cd = NetworkMapLink(NetworkMapLink.NORMAL, mapPage.findObjectElement(672).id, mapPage.findObjectElement(674).id) sList = ArrayList() sList.add(Long(674)) sList.add(Long(672)) cd.setStatusObjects(sList) cd.setRouting(NetworkMapLink.ROUTING_DIRECT) cd.setColorSource(LinkConfig.COLOR_SOURCE_OBJECT_STATUS) mapPage.addLink(cd) data = NXCObjectModificationData(2722) data.setMapContent(mapPage.getElements(), mapPage.getLinks()) s.modifyObject(data)

Here's an example of such script, that will change community string for all nodes, that have SNMP polling enabled newAuthName = 'public2' for node in [o for o in session.getAllObjects() if isinstance(o, objects.Node)]: # filter all objects for objects.Node if (node.getFlags() & Node.NF_DISABLE_SNMP) = 0: # SNMP polling is not disabled if (node.getSnmpAuthName() != newAuthName): print('Processing node %s: changing community string from %s to %s' % (node.objectName, node.getSnmpAuthName(), newAuthName)) md = NXCObjectModificationData(node.objectId) md.setSnmpAuthName(newAuthName) session.modifyObject(md) The script is launched like this: java -jar nxshell-3.1.241.jar script_name.py There are some examples of Jython scripts in netxms sources in src/client/nxshell/samples/ Some examples are also here: https://wiki.netxms.org/wiki/Using_nxshell_to_automate_bulk_operations Documentation of API calls is here: https://www.netxms.org/documentation/javadoc/latest/overview-summary.html

3.1 packags for raspbian buster have been released. Installation by installing https://packages.netxms.org/netxms-release-latest.deb in not working yet, so it's necessary to manually add deb http://packages.netxms.org/raspbian/ buster main into sources.list

Hi! Let me describe the whole configuration process for DS18x20 sensors on RPi in case if someone needs this later. A pull-up resistor of 2..10KOhm should be connected between DQ pin of the sensor and +3.3v. GPIO2 and GPIO3 have built-in 1.8KOhm pull-up resistors (at least on RPi 3), so if you don't need I2C, you can connect the sensor to one of these pins. A kernel module is used to communicate with the sensor. It is activated ty adding dtoverlay=w1-gpio to the end of /boot/config.txt file. By default the DQ pin of the sensor should be connected to GPIO4, to use another GPIO the following format could be used: dtoverlay=w1-gpio,gpiopin=3. Reboot RPi when finished editing the file. Since kernel version 4.9.28 it's also possible to use dynamic overlay loading: sudo dtoverlay w1-gpio gpiopin=5, in this way it's possible to have sensors on several GPIO pins. After restart (of after dynamic overlay loading) the sensors should get detected: root@raspberrypi:~# ls /sys/bus/w1/devices/ 28-6cb0611f64ff w1_bus_master1 here we have one sensor connected, it has name 28-6cb0611f64ff 4) And we should be able to read the temperature: root@raspberrypi:~# cat /sys/bus/w1/devices/28-6cb0611f64ff/w1_slave 78 01 55 00 7f ff 0c 10 57 : crc=57 YES 78 01 55 00 7f ff 0c 10 57 t=23500 which in this case is 23,5 degrees C. 5) To configure NetXMS agent we add the following lines to /etc/nxagentd.conf SubAgent=ds18x20.nsm [DS18X20] Sensor = Test:28-6cb0611f64ff After agent restart systemctl restart nxagentd our parameter "Test" should return the temperature. user@netxms-server:~$ nxget raspberrypi.lan 'Sensor.Temperature(Test)' 23.312 Your configuration looks exactly the same. The thing is that the error message in agent log "Unable to add sensor from configuration file. Original configuration record:" looks to be a bug, i am also getting it (as of v. 3.1.274). But the parameter works. Most probably on your system Sensor.Temperature(Test) will also give the result.

Which capabilities do you expect to be in "Yes" state? In may cases it's just enough to have isAgent Yes. Netxms agent provides a lot of monitoring options.

Current approach to templates in NetXMS has the idea, that all nodes, belonging to one template are absolutely the same. You could create a separate template for your exclusion cases and set up template autoapply scripts that would set correct template for a particular node. The other way could be to use the following syntax in threshold field %{custom_attribute_name:100} in template. In this case threshold value will be taken from a custom attribute, specified on a node and if such attribute is not present on a node, a default value of 100 will be used.

Thanks, Victor Works perfect !!

Issue was fixed by 3.1. Not really much help here. 

No, it is not possible without server source code changes. Best regards, Victor

Thanks for the info.

I've tried on my system with Postgres 10 and NetXMS 3.1.261 on Ubuntu 18.04 - the reconnect actually occurs. Can you increase debugging for DB operations, e.g. by running this from command line: nxadm -c "debug db.* 8" and show the log during the moment when database stops/restarts.

Thumbs up for this topic! To calculate Total Space Used on all filesystems, into single aggregate DCI: UsedSpaceTotal=0; foreach (dci : FindAllDCIs($node,"FileSystem.Used*") ) { dciValue = GetDCIValue($node,dci->id); if ( dciValue == null ) continue; // To skip in case of errors UsedSpaceTotal+=dciValue; } return UsedSpaceTotal;

Thanks for the information, In my case, the server in "Source" column in Syslog Monitor exists as a node in NetXMS. However, most of the computers in "Host Name" column do not exist as a node in NetXMS.

I wanted to follow up on how we fixed it. The radio devices have SNMP for virtual AP interfaces. We don't really care about these OIDs, plus they are all unique across formfactors/firmwares. So the trick is to use a working SNMP OID endpoint, poll it, then use a transformation script to replace the value. Example for geoLatitude_DMS: nodeLoc = $node->geolocation; return nodeLoc->latitudeText; [image: Screenshot from 2019-12-17 10-27-02.png] [image: Screenshot from 2019-12-17 10-30-28.png]

I believe we were simply running out of memory overall. In this dev environment it's sharing space with postgresql. In the latest release, my best guess is that netxms behavior changed, resulting in more concurrent database queries. I dramatically lowered the number of database pools in use, and so far netxms has been stable with no reduction in performance. (I am monitoring threads via DCIs.)
