How To Monitor Synology NAS With Zabbix Over SNMP v3

Posted on by

Today I will show you how you can monitor your Synology NAS (DSM 7.1) with Zabbix v6.2 over SNMPv3.

Note – These directions are for a setup on a local LAN (not over a WAN) and assume you have a working installation of Zabbix 6.2 running that has bi-drectional reach-ability to a Synology NAS running DSM v7.1

Phase 1 – Setup SNMPv3 on Zabbix server ->

1 – Update repositories and install libsnmp-dev

sudo apt-get update
sudo apt install libsnmp-dev

2 – stop snmpd demon

sudo service snmpd stop

3 – Create SNMPv3 user authPrivUser on Zabbix server

net-snmp-config --create-snmpv3-user -ro -a SHA -A "myauthphrase" -x AES -X "myprivphrase" authPrivUser

My Example:

sudo net-snmp-config --create-snmpv3-user -ro -a SHA -A "stringbean1" -x AES -X "stringbean2" authPrivUser

4 – Start snmpd service

sudo service snmpd start

Note – releveant conf files ->

/var/lib/snmp/snmpd.conf
/etc/snmp/snmpd.conf

Testing SNMPv3 user on Zabbix server with these commands ->

snmpget -v 3 -u authPrivUser -l AuthPriv -a SHA-512 -A myauthprhase -x AES -X myprivphrase 127.0.0.1 1.3.6.1.2.1.1.1.0

Test to actual host you want to monitor ->

snmpget -v 3 -u authPriveUser -l AuthPriv -a SHA-512 -A myauthprhase -x AES -X myprivphrase <client host ip> 1.3.6.1.2.1.1.1.0

Phase 2 – Configure SNMPv3 on Synology

1 – Navigate to control panel>search ‘snmp’ (terminal & snmp > SNMP)
2 – Check mark ‘enable SNMP service’
3 – Check mark ‘enable SNMPv3 service’
4 – Input username ‘authPriveUser’ (note – it is CASE SENSITIVE)
5 – Set protocol to ‘SHA’
6 – Set password (use whatever you set as ‘myauthphrase’ on Zabbix server)
6 – Check mark ‘enable SNMP privacy’
7 – Set protocol to ‘AES’
8 – Set password (use whatever you set as ‘myprivphrase’ on Zabbix server)

Phase 3 – Configure Zabbix host in Zabbix

1 – Download & install SNMPv3 zabbix template
(https://www.zabbix.com/integrations/synology)
2 – Create host in Zabbix
3 – For interfaces, click add>SNMP and change SNMP version to SNMPv3
4 – Change ‘security level’ to authPriv
5 – Set appropriate authentication protocol.

Note -‘authentication passphrase’ = ‘myauthprhase’ and ‘privacy passphrase’ = ‘myprivphrase’

Install Zabbix 6.4 On Ubuntu Server 22.04.1 In Under 10 Minutes

Posted on by

This guide will assume you have a working Ubuntu Server already installed with SSH enabled and ready to go. If you need help with installing Ubuntu server, refer here

If you’re more visual and prefer to watch an installation walk through, refer here

Aside from that, lets jump straight into installing Zabbix 6.4 PRE-RELEASE on top of Ubuntu Server 22.04.1 which as  the time of this writing, is latest and greatest versions of both ->

1. Install ubuntu server 22.04.1 and enable ssh

2. SSH to your Ubuntu server to run install commands

3. Install and configure Zabbix for your platform

Run the following cmds:

sudo wget https://repo.zabbix.com/zabbix/6.3/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.3-3%2Bubuntu22.04_all.deb
sudo dpkg -i zabbix-release_6.3-3+ubuntu22.04_all.deb
sudo apt update 
sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent

4. Install sql server

sudo apt-get install mysql-server
sudo systemctl start mysql

5. Create initial database

sudo mysql
create database zabbix character set utf8mb4 collate utf8mb4_bin;
create user zabbix@localhost identified by 'password';
grant all privileges on zabbix.* to zabbix@localhost;
set global log_bin_trust_function_creators = 1;
quit;

6. On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password.

sudo zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix

7. Disable log_bin_trust_function_creators option after importing database schema.

sudo mysql
set global log_bin_trust_function_creators = 0;
quit;

8. Configure the database for Zabbix server

Edit file /etc/zabbix/zabbix_server.conf and set the DB password with ->

sudo vim /etc/zabbix/zabbix_server.conf

9. Start Zabbix server and agent processes

systemctl restart zabbix-server zabbix-agent apache2
systemctl enable zabbix-server zabbix-agent apache2

10. Open Zabbix UI web page and proceed with web ui config (should be self explanatory)

The default URL for Zabbix UI when using Apache web server is http://host/zabbix
