Aaaaaah, there we go! Thanks a million for quick replies Dan.
For whom ever stumbles on my case facing the same problem, here is the
fixed configuration:
<localfile>
<log_format>full_command</log_format>
<command>ps -eo cmd |grep arpwatch</command>
<alias>ARPWATCH-check</alias>
</localfile>
<localfile>
<log_format>full_command</log_format>
<command>ps -eo cmd |grep dumpcap |sed -e
"s/\/[0-9]*-[0-9]*-[0-9]*\///g"</command>
<alias>DUMPCAP-check</alias>
</localfile>
<localfile>
<log_format>full_command</log_format>
<command>ps -eo cmd |grep com.objectplanet.probe</command>
<alias>NETWORKPROBE-check</alias>
</localfile>
