Hi guys,
I’m having kinda weird issue.
At link properties in data source I’ve referred to the right port rrd’s. All links show the bw properly.
But sometimes, the bw of non-particular links, suddenly fall into zero. Even if I refresh the map.
After a while everything is fine again.
Any idea whats the cause of this issue ?
When you say “Refresh the map” do you mean pressing refresh in the browser? Because that doesn’t do anything for the map - it just loads the same image again.
Check the logs (cacti.log) when this happens - see if you are getting warnings from WEATHERMAP ReadData in there.
I just noticed that the map refreshes itself periodically.
When I do nothing but watch the map refreshing, I see links showing 0 mb suddenly, while the link is technically up and running, and even the graph shows the proper data traffic.
Checking the log sounds a good idea.
Where is the log file located in librenms ?
No clue where the log is for librenms, sorry! Once you find it, if it offers no clues, maybe try enabling debug logging for weathermap. I think you will be running from a cron job, so you’d add --debug to the weathermap command line to get a LOT more information.
