Items collected
| Name | Description | Type | Interval | Key and additional info |
|---|---|---|---|---|
| ICMP ping | - | SIMPLE | - | icmpping |
| ICMP loss | - | SIMPLE | - | icmppingloss |
| ICMP response time | - | SIMPLE | - | icmppingsec |
| SNMP traps (fallback) | The item is used to collect all SNMP traps unmatched by other snmptrap items | SNMP_TRAP | - | snmptrap.fallback |
| System contact details | MIB: SNMPv2-MIB The textual identification of the contact person for this managed node, together with information on how to contact this person. If no contact information is known, the value is the zero-length string. | SNMP_AGENT | 15m | system.contact[sysContact.0] |
| System description | MIB: SNMPv2-MIB A textual description of the entity. This value should include the full name and version identification of the system's hardware type, software operating-system, and networking software. | SNMP_AGENT | 15m | system.descr[sysDescr.0] |
| System location | MIB: SNMPv2-MIB The physical location of this node (e.g., `telephone closet, 3rd floor'). If the location is unknown, the value is the zero-length string. | SNMP_AGENT | 15m | system.location[sysLocation.0] |
| System name | MIB: SNMPv2-MIB An administratively-assigned name for this managed node.By convention, this is the node's fully-qualified domain name. If the name is unknown, the value is the zero-length string. | SNMP_AGENT | 15m | system.name |
| System object ID | MIB: SNMPv2-MIB The vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determiningwhat kind of box' is being managed. For example, if vendorFlintstones, Inc.' was assigned the subtree1.3.6.1.4.1.4242, it could assign the identifier 1.3.6.1.4.1.4242.1.1 to its `Fred Router'. | SNMP_AGENT | 15m | system.objectid[sysObjectID.0] |
| Uptime | MIB: SNMPv2-MIB The time (in hundredths of a second) since the network management portion of the system was last re-initialized. | SNMP_AGENT | 30s | system.uptime[sysUpTime.0] |
| SNMP agent availability | Availability of SNMP checks on the host. The value of this item corresponds to availability icons in the host list. Possible value: 0 - not available 1 - available 2 - unknown | INTERNAL | - | zabbix[host,snmp,available] |
