I have logwatch - Checking log file and sending data to netxms alerts- this working fine.
How to create DCI from this - I have to create graphs for example:
message is : 15:52:51 23.3°C 4.44
I would like create graphs from 23.3 and 4.44 
Is this possible with netxms?
			
			
			
				Hi,
yes, it's possible. You can create two push DCIs and a script. Set this script as an action for your event, extract numbers from message text, and use PushDCIData (https://wiki.netxms.org/wiki/NXSL:PushDCIData) function to push data into appropriate DCIs.
Best regards,
Victor
