traceoptions (SNMP)
Syntax
traceoptions { file filename <files number> <match regular-expression> <size size> <world-readable | no-world-readable>; flag flag; no-remote-trace; }
Hierarchy Level
[edit snmp]
Description
Track the activities of SNMP agents on the switch and record the information in log files.
The traceoptions
statement is not supported
on the QFabric system.
The output of the tracing operations is placed into log files
in the /var/log directory. Each log
file is named after the SNMP agent that generates it. The following
logs are created in the /var/log directory
when the traceoptions
statement is used:
chassisd
craftd
ilmid
mib2d
rmopd
serviced
snmpd
Options
file filename—By default, the name of the log file that records trace output is the name of the process being traced (for example, mib2d or snmpd). Use this option to specify another name.
files number—(Optional) Maximum number of trace files per SNMP subagent. When a trace file (for example, snmpd) reaches its maximum size, it is archived by being renamed to snmpd.0. The previous snmpd.1 is renamed to snmpd.2, and so on. The oldest archived file is deleted.
Range: 2 through 1000 files
Default: 10 files
flag flag—Tracing operation to perform. To specify more than one tracing
operation, include multiple flag
statements:
all—Log all SNMP events.
configuration—Log reading of configuration at the
[edit snmp]
hierarchy level.
database—Log events involving storage and retrieval in the events database.
events—Log important events.
general—Log general events.
interface-stats—Log physical and logical interface statistics.
nonvolatile-sets—Log nonvolatile SNMP set request handling.
pdu—Log SNMP request and response packets.
policy—Log policy processing.
protocol-timeouts—Log SNMP response timeouts.
routing-socket—Log routing socket calls.
server—Log communication with processes that are generating events.
subagent—Log subagent restarts.
timer-events—Log internally generated events.
varbind-error—Log variable binding errors.
match regular-expression—(Optional) Refine the output to include lines that contain the regular expression.
size size—(Optional) Maximum size, in kilobytes (KB), of each trace file before it is closed and archived.
Range: 10 KB through 1 GB
Default: 1000 KB
world-readable | no-world-readable—(Optional) By default, log files can be accessed only by the
user who configures the tracing operation. The world-readable
option enables any user to read the file. To explicitly set the
default behavior, use the no-world-readable
option.
