Hi,

We need more info than that. Take a screenshot of the graph not drawing.

Is this a new install? Since when you dont have graphs? If you run ./poller.php -d -h affecteddevice do you get correct info and RRD Update? Does it happens in all graphs?

Regards,

yes! it’s new install.

Replace “affecteddevice”with one of your devices

Because the graphs are red, that means the rrd files haven’t been created yet. So either your poller isn’t running, or you have something wrong with your rrd config. Are you using rrdcached?

Hi murrant,

What should i do?

im using rrdcached.

Please help me to solve this issue…2wks still no data in my graph.

Since your using RRDcached then RRDTool must be version 1.5.5 or higher, see https://docs.librenms.org/Extensions/RRDCached/

11

@Chas you can use rrdcached with rrdtool < 1.5.5

What that message means is for distributed poller, and you can also run distributed poller with <1.5.5 using an NFS storage as rrd storage.

I think that message should be cleaner, as a lot of ppl confuses it…

Ahh ok thanks for explaining whoops
