Classify devices, network discovery, SNMPv2, the sequence

Create a community name:

 < /dev/urandom tr -dc A-Za-z0-9 | head -c${1:-20};echo;

Set this comunity name for each device behind a proxy:

eRQ57WF92NkqMFI6AnBV

Install snmp tools on Debian family:

apt-get -y install snmp

Install on RHEL family:

yum -y install net-snmp-utils

Test if device is accessible from proxy server. Show ObjectID:

snmpwalk -v2c -c eRQ57WF92NkqMFI6AnBV 192.168.99.1 .1.3.6.1.2.1.1.2.0

Set {$SNMP_COMMUNITY} to eRQ57WF92NkqMFI6AnBV in:

Administration -> General -> Macros

Set up network discovery in:

Configuration -> Discovery

SNMP community:

{$SNMP_COMMUNITY}

sysObjectID:

.1.3.6.1.2.1.1.2.0

For multiple proxies the image looks like:

Reload config on Zabbix server:

zabbix_server -R config_cache_reload

Reload config on Proxy server:

zabbix_proxy -R config_cache_reload

Make sure every requested metric comes to Zabbix server:

Monitoring -> Discovery

Take a note where every host after discovery will go by default:

Because the output may be different on multiple proxies:

# snmpwalk -v2c -c eRQ57WF92NkqMFI6AnBV 192.168.99.1 .1.3.6.1.2.1.1.2.0
SNMPv2-MIB::sysObjectID.0 = OID: MIKROTIK-MIB::mikrotikExperimentalModule
# snmpwalk -v2c -c eRQ57WF92NkqMFI6AnBV 192.168.88.1 .1.3.6.1.2.1.1.2.0
iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.14988.1

I need to create one value comparison with clear OID and the second with translated:

All together:

Reload config on Zabbix server:

zabbix_server -R config_cache_reload

Reload config on Proxy server:

zabbix_proxy -R config_cache_reload

Make sure the device registers as a monitored host:

Let's update the same registration but this time we will automatically create an snmpwalk dump for this device:

The command for proxy compiled from source:

/usr/local/share/zabbix/externalscripts/create-snmpwalk-dump.sh eRQ57WF92NkqMFI6AnBV {DISCOVERY.DEVICE.IPADDRESS}

On CentOS:

/usr/lib/zabbix/externalscripts/create-snmpwalk-dump.sh eRQ57WF92NkqMFI6AnBV {DISCOVERY.DEVICE.IPADDRESS}

The content of:

Make sure the home directory exists and is owned by user zabbix:

mkdir -p /home/zabbix && chown -R zabbix. /home/zabbix

The outcome from script will be the pure buletproof OID's + translated version if the proxy has appropriate MIBs:

# tree -a
