Please help.

Solution was to increase the Agent.CommandTimeout value  ::)

The Query does not run from the DCI Parameter Selection form too. But it runs and gives output from nxget.

Origin : NetXMS Agent
Metric : query4(1)
There's no transformation.

I think it has got something to do with query running time. If I simplify the select query then I do get output in the GUI.

It is giving correct output

C:\NetXMS\bin>nxget 10.14.50.30 query4(1)
90.7

I'm using v4.5.0
I have a query in agent configuration file which I'm polling in a DCI. It always gives <<ERROR>> output value. However, from the agent log below, I found that the query is indeed returning the intended output.

It is working now with below config:

ID = DB1
Name = <IPADDRESS>:<PORT NUMBER>/<SERVICE NAME>
Username = dbuser
Password = mypass123

Thanks for the '--with-oracle' suggestion. It worked.
Now, Oracle.DBInfo.IsReachable(DB1) is coming NO

SubAgent = oracle.nsm
[ORACLE]
ID = DB1
Name = TEST
Username = dbuser
Password = "mypass123"

 
I also tried below config but that didn't work either.
Select

SubAgent = oracle.nsm
[ORACLE]
ID = DB1
TnsName = TEST
Username = dbuser
Password = "mypass123"

 
I gave full connection string as below. Also didn't work.
Select

SubAgent = oracle.nsm
[ORACLE]
ID = DB1
Name = dbuser@//localhost:1521/TEST
Username = dbuser
Password = "mypass123"

Is there any difference between the INI formats of 4.5.0 and 5.x ? Id or ID? TnsName or Name?
Can't find Administration Guide for old versions.

In version 4.5.0 Oracle subagent is not getting loaded. Agent config file is as below:

I didn't keep a database backup. I don't know what to do now!!

This upgrade has proved to be too costly for me.

Windows event logs have the below MariaDB error:

Aborted connection 40 to db: 'netxms' user: 'netxms' host: 'localhost' (Got an error reading communication packets) 

Do I have to upgrade MariaDB?

Please help in resolving this issue.

I'm facing exactly the same issue. I didn't take database backup so cannot go back to the old schema version either.

Hi,

I upgraded from 4.5.6 to 5.0.2 and NetXMS server refuses to start. I'm using MariaDB 10.4. 

Your database has format version 50.32, but server is compiled for version 50.39

Running  nxdbmgr.exe upgrade has no effect/output either.

C:\NetXMS\bin>nxdbmgr.exe upgrade
NetXMS Database Manager Version 5.0.2 Build 5.0-878-gccaeca5869 (UNICODE)

Upgrading database...
Upgrading from version 50.32 to 50.33

C:\NetXMS\bin>

Please help.

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.

Regards,
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
Deep

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:

MasterServers = 10.14.50.82
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
