Zabbix SNMPv2 UCD-SNMP-MIB load average monitoring

Monitors system load average entry parameters exposed by the UCD-SNMP-MIB (University of California, Davis MIB) via SNMPv2

This template is part of RaBe's Zabbix template and helpers collection.

Usage

  1. Download the UCD-SNMP-MIB (if not already available on your system)
  2. Place the MIB file(s) into your default MIB directory on the Zabbix server and/or proxy (usually /usr/local/share/snmp/mibs) and make sure that the Zabbix server and/or proxy loads them (see Using and loading MIBs).
  3. Import the Template_SNMPv2_UCD-SNMP-MIB_load_average.xml into your Zabbix server (click on the Raw button to download).
  4. Add an SNMP interface configuration to your host
  5. Set the {$SNMP_COMMUNITY} macro to your desired community if you don't use public
  6. Add the template to your host (or stack template)
  7. Check if new data arrives

Notes

snmpwalk command

The following snmpwalk command might be helpful for debugging:

snmpwalk -v 2c -c public <HOST> UCD-SNMP-MIB::laTable

Template SNMPv2 UCD-SNMP-MIB load average

SNMPv2 template for monitoring the load average of a host exposing the UCD-SNMP-MIB (University of California, Davis MIB) laTable table.

Macros

  • {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_THRESHOLD} (default: 15)
  • {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_TIME} (default: 30m)
  • {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_THRESHOLD} (default: 15)
  • {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_TIME} (default: 15m)

Discovery

Load average entries (rabe.snmp.ucd-snmp-mib.laEntry.discovery)

Discovery of load average entries

Returns the following macro for each available load average entry (laEntry)

  • {#LA_INDEX}
    • Reference index/row number for each discovered load average entry (UCD-SNMP-MIB::laIndex)
  • {#LA_NAME}
    • The name of each discovered load average entry (UCD-SNMP-MIB::laNames).
Item Prototypes
  • Load watch point of "{#LA_NAME}" (rabe.snmp.ucd-snmp-mib.laConfig[{#SNMPINDEX}])
    The watch point for load-average {#LA_NAME} to signal an error.

If the load averages rises above this value, the laErrorFlag is set.

  • Load error message for "{#LA_NAME}" (rabe.snmp.ucd-snmp-mib.laErrMessage[{#SNMPINDEX}])
    An error message describing the load-average and its surpased watch-point value.
  • Error flag of "{#LA_NAME}" (rabe.snmp.ucd-snmp-mib.laErrorFlag[{#SNMPINDEX}])
    A Error flag to indicate the load-average has crossed its threshold value defined in the snmpd.conf file. It is set to 1 if the threshold is crossed, 0 otherwise.
  • Load "{#LA_NAME}" (rabe.snmp.ucd-snmp-mib.laLoad[{#SNMPINDEX}])
    The {#LA_NAME} minute load average.
Trigger Prototypes
  • Warning: Processor load is high (> $1 over {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_TIME:"{#LA_NAME}"} on {HOST.NAME} 
    {Template SNMPv2 UCD-SNMP-MIB load average:rabe.snmp.ucd-snmp-mib.laLoad[{#SNMPINDEX}].avg({$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_TIME:"{#LA_NAME}"})}>{$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_THRESHOLD:"{#LA_NAME}"}
    The average CPU load is over {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_TIME:"{#LA_NAME}"} for the last {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_WARNING_TIME:"{#LA_NAME}}.
  • High: Processor load is very high (> $1 over {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_TIME:"{#LA_NAME}"} on {HOST.NAME} 
    {Template SNMPv2 UCD-SNMP-MIB load average:rabe.snmp.ucd-snmp-mib.laLoad[{#SNMPINDEX}].avg({$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_TIME:"{#LA_NAME}"})}>{$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_THRESHOLD:"{#LA_NAME}"}
    The average CPU load is over {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_TIME:"{#LA_NAME}"} for the last {$SNMPV2_UCD_SNMP_MIB_LOAD_AVERAGE_CPU_LOAD_HIGH_TIME:"{#LA_NAME}"}.
  • Warning: Processor load {#LA_NAME} is higher than the system watch point ({ITEM.VALUE1} > {ITEM.VALUE2}) on {HOST.NAME}) 
    {Template SNMPv2 UCD-SNMP-MIB load average:rabe.snmp.ucd-snmp-mib.laLoad[{#SNMPINDEX}].last()}>{Template SNMPv2 UCD-SNMP-MIB load average:rabe.snmp.ucd-snmp-mib.laConfig[{#SNMPINDEX}].last()}
    The load average is higher than the system configured watch point (UCD-SNMP-MIB::laConfig).
