Hi,

It seems I have some conflict between the log parser and the ExternalParameter definition in a node configuration.
could you, please, let me know if I do sth wrong here?

Here is the agent log file when the following ExternalParameterShellExec is defined:
ExternalParameterShellExec = TCP.SocketStatus(*):/home/netxms/scripts/socket_status.pl $1 $2 $3 $4

Log file content:

One can easily see that logwatch subagent fails to initialize
If I remove the ExternalParameterShellExec fro mteh config file (commented out) here is the outcome:

Subagent logwatch successfully loaded.
Here is the config for the logwatch:

SubAgent = /usr/local/lib/libnsm_logwatch.so
*LOGWATCH
Parser = /home/netxms/parser/my_script_out.xml

Many thanks in advance fro your support.
Best regards,

Hehehe   I found the fix...

I'm sure many will come across that one as well so hope you'll find this post quickly and not waste too much of your time on this issue.

Well basically, it is just about defining the things according to a certain order in the agent config file. Unfortunately I cannot explain why but probably our NetXMS gurus will do later on...

This is how I defined it in my agent config file.
The only difference is that ExternalParameterShellExec is defined RIGHT after the subagent declaration. Then and only then comes the logwatch subagent declaration.

Agent config file extract:
SubAgent = /usr/local/lib/libnsm_linux.so
ExternalParameterShellExec = TCP.SocketStatus(*):/home/netxms/scripts/socket_status.pl $1 $2

SubAgent = /usr/local/lib/libnsm_logwatch.so
*LOGWATCH
Parser = /home/netxms/parser/log_parser_n2p.xml

Agent log file extract:

Hope this will be of any value to someone else.

Lines started with * character defines a new config section (usually subagent configuration) - and parameters allowed in each section are specific to this section. Core agent parameters should be defined in "default" section - unnamed section in the beginning of the file. Order within section is not important.
