[with the correct address list this time]
All:
Another issue with OpenBSD. Using the 'defaultMonitor' config with OpenBSD
3.7/i386 running Net-SNMP 5.2.1p1. At agent restart, I always get a trap from
the agent about swap:
example:
Jul 25 08:49:01 nmsHostname snmptrapd[72648]: 2005-07-25 08:49:01 hostname.com
[UDP: [192.168.1.1]:45160]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks:
(40857874) 4 days, 17:29:38.74 SNMPv2-MIB::snmpTrapOID.0 = OID:
DISMAN-EVENT-MIB::mteTriggerFired DISMAN-EVENT-MIB::mteHotTrigger = STRING:
memory DISMAN-EVENT-MIB::mteHotTargetName = STRING:
DISMAN-EVENT-MIB::mteHotContextName = STRING: DISMAN-EVENT-MIB::mteHotOID =
OID: UCD-SNMP-MIB::memSwapError.0 DISMAN-EVENT-MIB::mteHotValue = INTEGER: 1
UCD-SNMP-MIB::memErrorName.0 = STRING: swap UCD-SNMP-MIB::memSwapErrorMsg.0 =
STRING: Running out of swap space (0)
I'm not sure where DISMAN-EVENT-MIB is pulling information about swap (sysctl?
kernel? userland?), but it's erroneous in this case.
# swapctl -l
Device 1K-blocks Used Avail Capacity Priority
/dev/raid0a 2097024 0 2097024 0% 0
In UCD-SNMP-MIB.txt, the following is defined:
memMinimumSwap OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Minimum amount of free swap required to be free
or else memErrorSwap is set to 1 and an error string is
returned memSwapErrorMsg."
::= { memory 12 }
And that traces to net-snmp-5.2.1.2/agent/mibgroup/ucd-snmp/memory.h where
#define MEMSWAPMINIMUM 12
...I'll look into how FreeBSD and OpenBSD accumulate this value differently.
It's burried in the source somewhere.
