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
}
