Overview

up.time collects the configuration and performance data outlined in this article from Net-SNMP implementations. Additional performance data outside of this set can be collected using the SNMP service monitor with retained performance metrics.

List of Required Net-SNMP MIBs

All data that up.time gathers from Net-SNMP is based on the following MIB implementations:

  • RFC 1213 - Management Information Base for Network Management of TCP/IP-based internets

    Presents network interface information.

  • UCD-SNMP-MIB

    Presents general system state information.

  • Host Resources MIB (RFC 2790)

    Presents system performance data.

System Configuration Data

Metric Explanation Source MIB
sysName The name of the system on which Net-SNMP is running. RFC 1213 - sysName
sysDesc The hardware architecture of the system. RFC 1213 - sysDesc
hrDeviceTable up.time uses the following information returned by this metric: the number of CPUs on the system and the CPU configuration. HOST-RESOURCES-MIB - hrDeviceTable.
memTotalReal The amount of memory available on the system. UCD-SNMP-MIB - memTotalReal
memTotalSwap The size of swap space available on the system. UCD-SNMP-MIB - memTotalSwap
ifDescr The name of the network card that is installed on the system. RFC 1213 - interfaces/ifDescr
ifMtu The largest amount of data that the network interface can transmit in a single physical frame. RFC 1213 - interfaces/ifMtu
ifSpeed The maximum speed of the network interface. RFC 1213 - interfaces/ifSpeed
ifPhysAddress The physical address of the network interface. RFC 1213 - interfaces/ifPhysAddress

System Performance Data

Metric Explanation Source MIB
ssCpuUser The amount of time that the CPU on the system spends executing user processes. UCD-SNMP-MIB - systemstats/ssCpuUser
ssCpuSystem The amount of time that the CPU spends processing system calls. UCD-SNMP-MIB - systemstats/ssCpuSystem
ssCpuIdle The amount of time that the CPU is idle. UCD-SNMP-MIB - systemstats/ssCpuIdle
hrSystemProcesses The number of processes that are running on the system. HOST-RESOURCES-MIB - hrSystemProcesses
memTotalSwap The total amount of swap space on the system. UCD-SNMP-MIB - memory/memTotalSwap
memAvailSwap The amount of swap space that is available. UCD-SNMP-MIB - memory/memAvailSwap
memAvailReal The amount of available memory. UCD-SNMP-MIB - memory/memAvailReal
memTotalFree The total amount of free memory. UCD-SNMP-MIB - memory/memTotalFree
ifDescr The name of the network interface. RFC 1213 - interfaces/ifDescr
ifInOctects The amount of data, measured in octets, that is moving into the network interface. RFC 1213 - interfaces/ifInOctects
ifInErrors The number of inbound errors. RFC 1213 - interfaces/ifInErrors
ifOutOctects The amount of data, measured in octets, that is moving out of the network interface. RFC 1213 - interfaces/ifOutOctects
ifOutErrors The number of outbound errors. RFC 1213 - interfaces/ifOutErrors
hrStorageDescr A description of the file system. HOST-RESOURCES-MIB - hrStorage/hrStorageDescr
hrStorageSize The total amount of storage space on the file system. HOST-RESOURCES-MIB - hrStorage/hrStorageSize
hrStorageUsed The amount of storage space on the file system that has been used. HOST-RESOURCES-MIB - hrStorage/hrStorageUsed
hrSWRunName The name of a process that is currently running. HOST-RESOURCES-MIB - hrSWRun/hrSWRunName
hrSWRunIndex The ID of the process that is currently running. HOST-RESOURCES-MIB - hrSWRunIndex
hrSWRunPerfCPU The number of centi-seconds of the total system CPU resources that a running process is consuming. HOST-RESOURCES-MIB - hrSWRunPerf/hrSWRunPerfCPU
hrSWRunPerfMem The amount of memory that a running process is using. HOST-RESOURCES-MIB - hrSWRunPerf/hrSWRunPerfMem
hrSystemNumUsers The number of users currently active on the system. HOST-RESOURCES-MIB - hrSystemNumUsers
