« on: June 17, 2018, 07:42:20 am »

We are using NETXMS to MONITOR our optical Rx power of our network devices wherein we are getting the optical Rx Power in mW instead of dBm. please help us that how we get this Optical power values in dBm?

If your device only provides mW values, you will need to use a transform script on your DCI to convert to dBm.
The below should do it:
Code: [Select]
return 10*log10($1);

1 milliwatt = 1000 microwatt, therefore
Code: [Select]
return 10*log10($1/1000);will convert microwatt to dbm.
