Drawing graph error

Hi there,

Most of the graphs are working on my instance, however under the “Load” tab these graphs have errors with the following rrd command output:

ERROR: opening ‘/opt/librenms/rrd/<IP_ADDRESS>/ucd_load.rrd’: No such file or directory

Am I missing something in order to generate these files so the graphs can load?

My install is all up to date:


Component Version
LibreNMS dad2a5e9cc0ea3dc5115d2fe2f0d5d5547289ffe
DB Schema 176
PHP 7.0.16
MySQL 5.5.52-MariaDB
RRDTool 1.4.8


[OK] Database connection successful

Any help would be appreciated.

Thank you.

Can you provide the link you are clicking (without the domain) to get to that graph please.

Thanks for replying.

The link I’m clicking is:



Please link the output of:

./poller.php -h 3 -r -f -m ucd-mib | ./pbin.sh


Thank you,

Yeah I totally missed the -d :frowning:

./poller.php -h 3 -r -f -m ucd-mib -d | ./pbin.sh

haha no worries :slight_smile:

Your device isn’t returning the data, ensure you aren’t restricting any snmp options in snmpd.conf (see our example file included in your install).

Thanks for this!

Unfortunately the snmpd.conf is the same as of that in the example config (minus the change to the “RANDOMSTRINGGOESHERE” which is now the community string).

So I guess the switches just won’t output the ucd_load data and there’s nothing I can do about it?

Thanks again, I really appreciate your help.

What switches?
