SNMP Setup for sending information

Linux

CentOS 7 Install

  • yum install net-snmp
  • systemctl enable snmpd
  • systemctl start snmpd

Service Setup

  • curl -o /usr/local/bin/distro https://gitlab.com/observium/distroscript/raw/master/distro
  • chmod +x /usr/local/bin/distro
  • mpd.conf:
  • extend .1.3.6.1.4.1.2021.7890.1 distro /usr/local/bin/distro
  • extend .1.3.6.1.4.1.2021.7890.2 hardware /bin/cat /sys/devices/virtual/dmi/id/product_name
  • extend .1.3.6.1.4.1.2021.7890.3 vendor /bin/cat /sys/devices/virtual/dmi/id/sys_vendor
  • extend .1.3.6.1.4.1.2021.7890.4 serial /bin/cat /sys/devices/virtual/dmi/id/product_serial
  • extend uptime /bin/cat /proc/uptime

In some environments snmpd not have permission for read file /sys/devices/virtual/dmi/id/product_serial. Need to change file permission at boot by adding this command to /etc/rc.local: chmod 444 /sys/devices/virtual/dmi/id/product_serial
