NAM-2, port stats appear and disappear toggle when enable the autorefresh

[cjrchoi11]

I installed NAM-2 module in the 6513 switch and have a question the port stats through miniRMON.

- 6513 SUP720, 12.2(17d)SBX

- WS-SVC-NAM-2, 3.3.1 patch 3.

- enable miniRMON

- polling interval=60sec

I can monitoring the switch port stats from the the NAM's Monitor menu but the stats toggle that appear and disappear every 60sec(enabled autorefresh). usually not showing anything(the message is no data available at this period) and sometimes showing properly. the 6513 switch is pretty busy so it's impossible no data for a minute.

Any idea why appear and disappear the port stats in the Monitor menu when autorefresh enabled ?

Thanks,

Some times, this will work out if you change polling intereval.
