NAME

       snmpfailures - Displays SNMP collector failures.

SYNOPSIS

       torrus snmpfailures --tree=TREENAME [options...]

OPTIONS

       --details
           In addition to failure counters, list the failed SNMP hosts and the time stamps of
           failure events.

       --help
           Displays a help message.

DESCRIPTION

       This utility prints the SNMP collector failure information in JSON format.  Without
       --details option, it prints only the failure counters.

       Upon collector startup or after the tree re-compilation, the failure counters are reset to
       zero.

       The output is very convenient for further automatic processing in any scripting language.

       The top level of the output is a JSON object with the following name/value pairs:

       total_unreachable: NUMBER
           Displays the number SNMP hosts that are currently unreachable.  The number adds up
           across multiple collector instances for a given tree.  If a host becomes reachable
           again, the number is decreased.

       total_deleted: NUMBER
           Displays the number SNMP hosts that are completely removed from SNMP collection for
           the life cycle of the collector process. This happens when a host is unreachable for
           too long time and the collector gives up to reach it again.  The number adds up across
           multiple collector instances for a given tree.

       total_mib_errors: NUMBER
           Displays the number of MIB errors (noSuchObject, noSuchInstance, and endOfMibView)
           during the collector life cycle.  The number adds up across multiple collector
           instances for a given tree.

       detail_unreachable: OBJECT, detail_deleted: OBJECT
           If the option --details is specified, these objects contain the host names and
           timestamps of the failures.  The keys are contactenations of SNMP host, UDP port, and
           SNMP community separated by "|".  The values are objects representing the UNIX
           timestamp and a human-readable time string.

       detail_mib_errors: OBJECT
           If the option --details is specified, this object displays the MIB error details: for
           each SNMP host, it lists the datasource leaves which had these errors and the event
           timestamps.

EXAMPLES

       The following example illustrates an SNMP host unreachable:

        torrus failures --tree=main --details
        {
           "detail_deleted" : {},
           "detail_mib_errors" : {},
           "detail_unreachable" : {
              "217.101.101.101|161|public" : {
                 "time" : "Fri Jul 23 14:15:10 2010",
                 "timestamp" : 1279887310
              }
           },
           "total_deleted" : 0,
           "total_mib_errors" : 0,
           "total_unreachable" : 1
        }

       The following example illustrates a MIB error:

        torrus failures --tree=main --details
        {
           "detail_deleted" : {},
           "detail_mib_errors" : {
              "217.101.102.102|161|public" : {
                 "count" : 1,
                 "nodes" : {
                    "/Routers/CMTS3/Temperature_Sensors/sensor_01" : {
                       "time" : "Fri Jul 23 15:26:14 2010",
                       "timestamp" : 1279891574
                    }
                 }
              }
           },
           "detail_unreachable" : {},
           "total_deleted" : 0,
           "total_mib_errors" : 1,
           "total_unreachable" : 0
        }
