Upgraded to v4.5.6 but the problem with maps persists. 

Hi,

I am reading SNMP  Objects ifHCOutOctets(Counter64) and ifHCInOctets ( Counter64 ) from switch interfaces every 60 secs and then Transformation Average Delta Per Second along with script $1*8 to get interface bandwidth in bits/sec. The problem is that this is giving me exaggerated values in full load condition - consider 11 or 12 Mbps on a 10 Mbps channel. Please help in sorting this issue.

Deep

Hi,

Ever since I upgraded to v4.5.4 I've observed that changes made in maps (like creating a link, changing text box color etc.) are not getting saved sometimes. The problem is erratic. Please help to resolve this issue.

Thanks

It didn't make any difference. Same error.

Hi Victor,

The agent is installed on a Windows machine, so I replaced the jmx.jar at \lib\java and now I'm getting the below given error:

Agent config file is as below:

ConfigIncludeDir = C:\NetXMS\etc\nxagentd.conf.d
LogFile = C:\NetXMS\log\nxagentd.log
FileStore = C:\NetXMS\var
SubAgent = winperf.nsm
SubAgent = java.nsm
DebugLevel = 6

[JAVA]
Jvm = C:\Program Files\Java\jdk1.8.0_202\jre\bin\server\jvm.dll
Classpath = C:\NetXMS\lib\java\tools.jar;C:\NetXMS\lib\java\jboss-client.jar;C:\NetXMS\lib\java\jboss-cli-client.jar;
Plugin = jmx.jar

[JMX]
Server = name:service:jmx:remote+http://localhost:9990

Added jboss-client.jar using Classpath but that didn't solve the problem. Still getting  java.net.MalformedURLException: Unsupported protocol: remote+http

I'm using Server = name:service:jmx:remote+http://localhost:9990 as applicable for JBoss EAP 7.1/Wildfly 11

This is throwing, Exception in parameter handler: java.net.MalformedURLException: Unsupported protocol: remote+http

I'm supposed to include jboss-client.jar in the application(netxms agent) classpath. Is it possible in NetXMS agent to include an external jar?

Hi,

So, in agent configuration file, under [JMX] if I define Server=servername:login/password@url, then Parameter becomes  JMX.Memory.Heap.Current(servername), right? And if I'm connecting to local Wildfly JMX then I should write Server=servername:wildfly/wildfly@localhost:9990. Is this OK? I'm confused about how to mention the port number.
 I have tried all 3 formats, none working.
1. name:url
2. name:login@url
3. name:login/password@url

Though I'm able to connect to local Wildfly through JConsole/VisualVM.

Please guide.

Deep

Hi,

I'm new to NetXMS and want to monitor JVM as given in JVM monitoring — NetXMS Administrator Guide (4.4.3).
 
I have created new DCI parameter as below:

Parameter : JMX.Memory.Heap.Current({instance})
Instance Discovery Method : Agent List

What should be the List name? Is any filtering script required?  Please help!
