Hi Thomas,
FYI...
I have changed a small line in get_swapinfo function of
agent/mibgroup/hardware/memory/memory_hpux.c
Before:
119 }
120 mem->units = pss.pss_swapchunk;
121 mem->size = pss.pss_nblksenabled; /* Or
pss_nblks ? */
122 mem->free = pss.pss_nfpgs; /* Or
pss_nblksavail ? */
123 mem->other = -1;
124 *total += mem->size;
125 *free +=mem->other;
After:
119 }
120 mem->units = pss.pss_swapchunk;
121 mem->size = pss.pss_nblksenabled; /* Or
pss_nblks ? */
122 mem->free = pss.pss_nfpgs; /* Or
pss_nblksavail ? */
123 mem->other = -1;
124 *total += mem->size;
125 *free +=mem->free; //changed line
Then i got the following o/p for when i run the modified snmpwalk command
# /opt/iexpress/net-snmp/bin/snmpwalk -v 1 -c public 127.0.0.1 UCD
UCD-SNMP-MIB::memIndex.0 = INTEGER: 0
UCD-SNMP-MIB::memErrorName.0 = STRING: swap
UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 8388608 kB
UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 1464754 kB
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 4192256 kB
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 231892 kB
But my swapinfo shows
#swapinfo
Kb Kb Kb PCT START/ Kb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 4194304 1264796 2929508 30% 0 - 1 /dev/vg00/lvol2
reserve - 873836 -873836
memory 4192256 1979540 2212716 47%
So i have taken the old hpux_memory.c file present in ucd-snmp dir as
reference and implemeted a sample program which computes the swap_space in
hp_ux.This file o/p is giving the exact value 292950
Attaching the file i used to get the swap information
Thanks & Regards,
Ravindranath
