[1 minute rrd setting] graph refresh not sharply at all

[lambda89]

Hello there,

I am monitoring trafic through two opnsense firewalls

Once trafic is established I shut the iperf tool down

Code: Select all

But it takes extra minutes to show the link report no trafic anymore

I don’t understand the behavior, since my .rrd updates successfully every minutes once I break the bandwidth iperf test the next update (the one at 22:20 184-185%) must show bandwidth as zero ?
Images above show the bandwidth comes up as intermediates values progressivly decreasing to show a full available link at 22:22 (which is really very laggy)

Does my poller/1-minute polling is not working or is it normal cacti weathermap behavior ?

(hope my query is understandable)

thx you

Hello

Since this topic focus on weathermap-plugins, it may not be at the right place.

Seems correlated but graphs reflects the described behavior (gradually decrease does not reflect real ground scenario)

Any hints appreciated
