Let Zabbix automatically discover and start monitoring your SNMP data points.
Creating items manually for each network interface, fan, temperature sensor, and other SNMP data points can be a very time-consuming task. To save time, Zabbix administrators need to automate item, trigger, and graph creation as much as possible.
Automate item, trigger and graph creation with SNMP low-level discovery rules:
- An entity will be created for each of the discovered indexes
- Specify multiple OIDs to discover additional information about an entity
- Filter entities based on any of the discovered OID values
- Low-level discovery can be used with SNMP v1, v2c and v3
Check out the video to learn how to use Zabbix low-level discovery to discover SNMP entities.
How to use Zabbix low-level discovery to discover SNMP entities:
- Navigate to Configuration → Hosts and find your SNMP host
- Open the Discovery section and create a discovery rule
- Provide a name, a key, and select the Type – SNMP agent
- Populate the SNMP OID field with the following LLD syntax
- discovery[{#LLD.MACRO1},<OID1>,{#LLD.MACRO2},<OID2>]
- Navigate to the Filters section and provide the LLD filters
- Press Add to create the LLD rule
- Open the Item prototypes section and create an item prototype
- Provide the Item prototype name and key
- Populate the OID field ending it with the {#SNMPINDEX} LLD macro
- Configure the required tags and preprocessing rules
- Press Add to create the item prototype
- Wait for the LLD rule to execute and observe the discovered items
Tips and best practices
- snmpwalk tool can be used to list the OIDs provided by the monitored device
- If a particular entity does not have the specified OID, the corresponding macro will be omitted for it
- OIDs can be added to your LLD rule for usage in filters and tags
- The {#SNMPINDEX} LLD macro is discovered automatically based on the indexes listed for each OID in the LLD rule
