SNMP settings

SSL Settings are available in the Control Panel.

U-alarm can be monitored by standard monitoring tools like Nagios, Zabbix, LibreNMS etc. using Simple Network Monitoring Protocol (SNMP). Only read only queries are supported via SNMPv1 or v2c.

Note: The Allowed Hosts field only accepts IP addresses, for example:

192.168.0.1/24

The following subtrees are supported:

  • SNMPv2-MIB::system (.1.3.6.1.2.1.1)
  • SNMPv2-MIB::hrSystemUptime (.1.3.6.1.2.1.25.1)
  • SNMPv2-MIB::hrStorage (.1.3.6.1.2.1.25.2)
  • SNMPv2-MIB::hrProcessorTable (.1.3.6.1.2.1.25.3.3)
  • UCD-SNMP-MIB::memory (.1.3.6.1.4.1.2021.4)
  • UCD-SNMP-MIB::laTable (.1.3.6.1.4.1.2021.10)
  • UCD-SNMP-MIB::systemStats (.1.3.6.1.4.1.2021.11)
  • ULTINOUS-UALARM-MIB:: (.1.3.6.1.4.1.57090.1.1)

Aside from the last one, they are well supported by monitoring tools, often auto-discovered or templates are offered. Currently only one U-alarm specific data is available via SNMP, which is the overall healthiness of the software components. Its oid is .1.3.6.1.4.1.57090.1.1.1.1.0

It is an Integer enumeration,

  • a value of 1 (one) stands for healthy status,

  • value of 2 (two) for error state.

Should your monitoring system require it, the MIB can be downloaded from: https://assets.ultinous.com/u-alarm/support/UALARM-MIB.txt

A Zabbix template is available at: https://assets.ultinous.com/u-alarm/support/zbx_ultinous_ualarm_templates.xml

It is created and tested on Zabbix 5.0 and depends on the following external templates: https://share.zabbix.com/network_devices/generic/ucd-snmp-mib-memory-monitoring https://share.zabbix.com/network_devices/generic/ucd-snmp-mib-load-average-monitoring

For other monitoring systems, refer to their manual about adding custom oid.
