Processor Usage and Storage Usage No Graph

Help
1

Hi, please help me…
If i am in the wrong place, please let me know.

my libreNMS can’t show the Processor Usage and Storage Usage graph.
For localhost that i have added can show graph of processor usage but not with storage usage including the another host that i have added.
My localhost OS and installed libreNMS is CentOS 7 and my another host is FreeBSD 11.1.
and this output of ./validate.php

[root@nms librenms]# ./validate.php

Component Version
LibreNMS 1.33-199-gb9dc777
DB Schema 221
PHP 7.1.11
MySQL 10.2.11-MariaDB
RRDTool 1.4.8
SNMP NET-SNMP 5.7.2

====================================

[OK] Database connection successful
[OK] Database schema correct
[FAIL] Discovery has never run. Check the cron job

Forgive me if you are confused with my english.
I have tried the all solutions i can found but not succeeded yet.
Thanks for anyone who wants to help

you need to check and see why your discovery is not working its inside /etc/cron.d/librenms

what do you think is wrong with my cronjob file? i have never edited this file before.

@laf i have use that file …this my snmpd.conf file

#Change libreNMS to your preferred SNMP community string
com2sec readonly default libreNMS

group MyROGroup v2c readonly
view all included .1 80
access MyROGroup “” any noauth exact all none none

#Update the location here
syslocation City, Country [GPSX,Y]
syscontact admin [email protected]

#Distro Detection
extend .1.3.6.1.4.1.2021.7890.1 distro /usr/bin/distro

OK, it has solved now…
I realize librenms cron script didn’t run well after ./daily.sh don’t running too…
So i added some line on the top crontab of librenms like this

SHELL=/bin/bash
PATH=/opt/librenms:/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

just my humble suggestion
maybe can added in librenms.nonroot.cron too in librenms source
Thanks for assistance
