Convert MIBs Files to Zabbix Templates
Video Lecture
Description
MIB files can be analysed and converted to Zabbix templates containing Items, Discovery Rules and Value Types.
One script for doing this is called mib2zabbix and can be downloaded from https://github.com/cavaliercoder/mib2zabbix.
Before running this script, you should already have the required SNMP dependencies installed and configured correctly.
On Ubuntu and other Debian based systems,
sudo apt-get update
sudo apt install snmp
sudo apt install snmp-mibs-downloader
On Centos and other Red-Hat based systems
yum check-update
yum install net-snmp-utils
yum install net-snmp-libs
Now configure the snmp.conf to return MIBs descriptions.
sudo nano /etc/snmp/snmp.conf
Comment out the mibs line like this,
#mibs
Do a simple test.
snmptranslate 1.3.6.1.2.1.1
SNMPv2-MIB::system
This is a MIB description of the OID 1.3.6.1.2.1.1
snmptranslate is now able to translate, and this is required before you can continue.
mib2zabbix.pl is written in perl, so you will need to install the perl dependencies.
On Ubuntu
apt-get install perl libxml-simple-perl libsnmp-perl
On Centos
yum install "perl(SNMP)" "perl(XML::Simple)"
Note
On CentOS 8, you may get the error that the perl snmp libs cannot be found. You can download the rpm first from rpm -ivh http://repo.okay.com.mx/centos/8/x86_64/release/okay-release-1-3.el8.noarch.rpm and then try again.
Next, get the mib2zabbix perl script
curl https://raw.githubusercontent.com/cavaliercoder/mib2zabbix/master/mib2zabbix.pl > mib2zabbix
wget -O mib2zabbix https://raw.githubusercontent.com/cavaliercoder/mib2zabbix/master/mib2zabbix.pl
Give the mib2zabbix file execute permissions.
chmod a+x mib2zabbix
Test it
./mib2zabbix -h
The response should be
Usage:
mib2zabbix.pl -o <OID> [OPTIONS]...
Export loaded SNMP MIB OIDs to Zabbix Template XML
-f, --filename=PATH output filename (default: stdout)
-N, --name=STRING template name (default: OID label)
-G, --group=STRING template group (default: 'Templates')
-e, --enable-items enable all template items (default: disabled)
-o, --oid=STRING OID tree root to export
-v, --snmpver=1|2|3 SNMP version (default: 2)
-p, --port=PORT SNMP UDP port number (default: 161)
SNMP Version 1 or 2c specific
-c, --community=STRING SNMP community string (default: 'public')
SNMP Version 3 specific
-L, --level=LEVEL security level (noAuthNoPriv|authNoPriv|authPriv)
-n, --context=CONTEXT context name
-u, --username=USERNAME security name
-a, --auth=PROTOCOL authentication protocol (MD5|SHA)
-A, --authpass=PASSPHRASE authentication protocol passphrase
-x, --privacy=PROTOCOL privacy protocol (DES|AES)
-X, --privpass=PASSPHRASE privacy passphrase
Zabbix item configuration
--check-delay=SECONDS check interval in seconds (default: 60)
--disc-delay=SECONDS discovery interval in seconds (default: 3600)
--history=DAYS history retention in days (default: 7)
--trends=DAYS trends retention in days (default: 365)
-h, --help print this message
If you get anything else then perl was not installed properly or it cannot find mib2zabbix. Check the error in the console.
Now to ensure you have the required MIB file that you want to convert.
A good example may be the HUAWEI-MIB.mib.
You can usually find the MIB files you need on the internet.
You can download the HUAWEI-MIB.mib from here.
curl http://www.circitor.fr/Mibs/Mib/H/HUAWEI-MIB.mib > HUAWEI-MIB.mib
wget -O HUAWEI-MIB.mib http://www.circitor.fr/Mibs/Mib/H/HUAWEI-MIB.mib
Next, see if snmptranslate can read this file.
snmptranslate -Tz -m ./HUAWEI-MIB.mib
You should see this plus many more lines showing the MIBs and their OIDs,
"org" "1.3"
"dod" "1.3.6"
"internet" "1.3.6.1"
"directory" "1.3.6.1.1"
"mgmt" "1.3.6.1.2"
"mib-2" "1.3.6.1.2.1"
...
Now it is time to convert it to a template for Zabbix by piping the snmptranslate response into mib2zabbix.
snmptranslate -Tz -m ./HUAWEI-MIB.mib | ./mib2zabbix -o .1.3.6.1.4.1 -f template-huawei-mib.xml -N huawei-mib
This will create a new file called template-huawei-mib.xml with the name huawei-mib within the xml.
Eg,
1 2 3 4 5 6 7 8 9 10 11 12 13 | |
This new xml file can be imported into Zabbix
Notes
See video for a more detailed demonstration and recommendations. Also note that all items, discovery rules and their item prototypes will be disabled by default. You should decide which is important to enable for your needs based on the devices official documentation. Enabling all items, discovery rules and their item prototypes may put unnecessary strain on your Zabbix server resources and the SNMP device so it is important to check what you actually need.
