so i added device localhost but none of the graph are showing any data, cpu memory, space, pingresponse or anything. I did add snmp config so it connects correctly.

it couldnt poll my localhost even i used the correct snmp config and have this added in config.php
$config[‘nets’][] = “255.255.255.252”;
$config[‘discovery_by_ip’] = true;
$config[‘snmp’][‘community’][] = “servermon”;
Thats coz its not added. What error do you get when you try to add localhost?
Have you enabled snmp in localhost?
i added localhost through librenms many times but not showing any graph or data in any systems. got no error aswell when i added localhost as device

Do you have localhost in your devices list?
Ok. Then the issue is in your snmpd.conf
Try changing this line:
access MyROGroup "" any noauth exact all none none
to this one
access MyROGroup "" any noauth exact AllView none none
Then reload snmp and rediscover device with ./discovery.php -h 127.0.0.1
Discovery must be run as librenms user
hi logged in as librenms i get and applied following changes didnt work
[09:03][librenms@user ~]$ ./discovery.php -h 127.0.0.1

OMG. Check what device id it is then ./discovery.php -d -h DEVICEID same with poller after discovery
Sorry for driving you insane.
My localhost that i added in librenms has device ID of 7
the graph isnt updating now however it is showing
and the result of executing
./discovery.php -d -h 7
and poller but i get

Could it be you didnt pasted full output?
Without it, I cant see if there were any error updating the rrd…
Also, when you post things like that, make sure you use three backticks ``` at start and end, so it shows as it does now in your posts. Hope you dont mind I’ve edited them to format that parts
I apologize for the lack of formatting, i was trying to find code block or anything to make it easier on the editor but couldnt find it. I know now the proper formatting settings
indeed, i didnt include the entire output due to sheer size but ive attached the output of
./discovery.php -d -h 7
Output:

./poller.php -d -h 7

I overlooked and everything seems ok… Maybe someone else join the conversation and can give us a hint on here
from discovery output i noticed i get alot of this error

changed to dispatcher hoping it was cronjob issue but it wasnt…
on a fresh reinstall, wiped database, the graph does not produce any data
