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
	}
