NetXMS Support Forum

Thank you for pointing me in the right direction, I had not created the webhook correctly.

I have installed a new NetXMS system on an Ubuntu server to test the newest release and some new ideas for our existing install.

Previously we had used email for our alerting platform, but it has some issues, and we would like to attempt to use Slack as a possible alterantive, however when I configure the Notification Channel for Slack I am not getting anywhere and the error on the Notification Channel setup is Status: failure, Error Message: Driver Error

It is a brand new base install of NetXMS with the WebGui added... and a few nodes monitored.

I have configured a webhook for slack, and added the following configuration in the Notification Channel setup for Slack:

username=monitor
url=[https://hooks.slack.com/services/***** private info here *****]

I am not sure what I am doing wrong?

Thank you.
 

Thank you very much for pointing out my error, however, I have attempted the download of the .war file that you gave the link for and I also have done it for 
https://netxms.com/download/releases/5.0/nxmc-5.0.8.war, which is the version of NETMXS that my server is running... 

But in either case I now get a 404 not found error, but I am not sure how to troubleshoot why I am not getting the web console.

I have been upgrading my NetXMS system, and I back fighting the web console that I gave up on a while ago.

Current system is a Ubuntu 18.04 server, running NetXMS 5.0.8, system works fine with a management console from a windows PC.

I have run the gambit of install / reinstall / remove various web systems, and followed the instructions from :

https://netxms.org/documentation/adminguide/installation.html#how-to-configure-the-netxms-web-client-with-jetty-in-linux

I upgraded Java from 11 to 17, here is the info on the JAVA on the server:
openjdk version "17.0.7" 2023-04-18
OpenJDK Runtime Environment (build 17.0.7+7-Ubuntu-0ubuntu118.04)
OpenJDK 64-Bit Server VM (build 17.0.7+7-Ubuntu-0ubuntu118.04, mixed mode, sharing)

Currently, I have attempted both Tomcat 9, and Jetty, running Java version 17, and with either web platform I get the following page when I go the site that should display the web console:

{"description":"NetXMS web service API version 5.0.8","version":"5.0.8","build":"5.0-1066-g6c885ac8ec"}

I don't know where to look now or what I am doing wrong... the .war file appears to be correct and in the correct place.

Please let me know if you all have any suggestions... Thank you!

Update, for anyone trying to do anything similar, I believe I have a working solution.  I was able create a polled DCI parameter from a Windows Agent using the SSH.nsm subagent to access a router / firewall and then run a script from that device ( in my case Edgerouter ).  Below is how I setup the DCI properties on the Windows Agent System:

Data - Parameter:
SSH.Command(192.168.239.1,username, password,sudo /config/scripts/polling_script.sh)

Origin:
NetXMS Agent 
   ( this differs from information online that says it should be "SSH", I could not get this to work )

Data Type:
String

Source Node:
Pointing at the Same windows Agent

I run a script that is found on the remote router / firewall that consist of a ping command that is parsed for information on if the ping is successful and returns either "OK" or "Failed"

my script is similar to this:
if ping -q -c 1 10.200.200.112 2>&1 > /dev/null ; then
    echo "Ok"
else
    echo "Fail"
fi


Thank you all for your help, this will allow me to confirm the status of VPN's that I do not control any remote devices, that only allow certain IP's to ping them.

Thank you for your input Zebbie, I figured once I got any info other than <<error>> on the DCI parameter then I would begin the process of parsing the data as you recommend.

Ok, I beleive I am making progress.

I have created a DCI parameter on a test PC - windows 10 running NetXMS agent with SSH.nsm subagent.

I have created a DCI parameter as follows:
Parameter:
   SSH.Command(192.168.239.1,username,password,ping 192.168.240.1)

Origin:
   NetXMS agent

Data Type:
   String

I have tried using the origin of SSH but I never get anything back. 

With the above settings I now see this in the log:



2021.02.15 08:51:45.001 *D* [comm.cs.2          ] Requesting parameter "SSH.Command(192.168.239.1,username,password,ping 192.168.240.1)"
2021.02.15 08:51:46.157 *D* [                   ] SSH: created new session [email protected]:22/2


So I am presumably getting a return of "created new session..."

How can I use this to SSH into my device, and ping another device and return the result of "successful" or "failed"??


Thank you all for your assistance.

I have continued testing with the log verbose setting to 6.  In the Agent log, that is a windows 10 system that I am attempting to use an ssh DCI parameter, the agent log does say that the SSH sub agent is loaded successfully, however the DCI parameter is never mentioned in the log.  I have other custom DCI parameters on this test machine and they do show up in the log.

Thank you Victor, I will do that and review, but if you could explain to me in simple terms exactly where these items should be configured.  I presume the DCI parameter should be created on the agent PC node, not the router in question?  I am confused as to where each of these items should actually be created.

I have attempted to create a DCI for a given node using only the "uname -a" under the DCI parameter.  I have the Origin set to SSH, and the Data Type to String. This is to attempt to get anything back in the DCI value.

I have attempted entering the NetXMS server and a windows 10 system running with NetXMS agent with the ssh.nsm enabled.  I have also attempted setting the windows 10 system as the SSH proxy, nether of these configurations work.

The only information that I get is an <<error>> in the value of the DCI when I force a DCI poll or just wait.

Obviously I am missing something or doing something wrong, can you assist further?

I have been reading up on scripting with SSH and NETXMS and various items about NXSL without much success.

I believe what I want to do is fairly simple but I don't understand how to implement it in NetXMS.

I monitor many Unifi Edgerouters with NetXMS, some of these firewalls have VPN's to remote subnets / devices that I would like to confirm the state of the VPN as up or down.  One way to do this is to ping a device on the other end of the VPN that also has the benefit of causing traffic to keep the VPN's up.  Since the Edgerouters do not have a NetXMS agent installed I don't know how to implement a script from the device like I do with other agents.  I believe it should be just an SSH script but I don't know how to get NetXMS to fire the script and record the output.

Basically I want to be able to run an SSH script on a non agent device to ping or other functions and return information.  I would also like to do this on a schedule if possible or during polling.

Any ideas on how to implement this?

Hello all, I am hoping someone can assist me with a issue that I would like to solve.  I am using NetXMS to monitor various devices and networks.  One network has an EdgeRouter Pro router / firewall that I am monitoring.  This firewall has a VPN to a remote network that I would like to alert on if the VPN is not up.  However, since it is a policy based VPN there is no interface to monitor.

The Edgerouter is basically a linux box that I can SSH into, so is there a way to run a script that I could run CLI commands via SSH to parse information to see if the tunnel is up, or possibly even force a ping / or initiate the vpn to retry?  I have not done any scripting with NetXMS so I am not familiar with where to start.

Thank you all for your assistance on this matter.

I tried this, and after a bit of messing with it still no luck.  I was able to get through the "sudo make install" but the files under the folder:

pi@pi4:~/NetXMS/netxms-3.0.2258/contrib/startup/systemd $ ls
Makefile  Makefile.am  Makefile.in  netxmsd.in  nxagentd.in  README

do not include the build service file after the make.

It it possible to have an ARMF capable agent install for the raspberry pi 3?

I am building various systems that use raspberry pi's to interact with physical environments and would like to be able to monitor them.

I should mention I have attempted to install the deb package that was created a while back but the prerequisites of that install conflict with my modern versions.

I think I got it I had a bad entry in my sources list with the NetXMS repository.
