Hi all,
We try to monitor the virtual memory used on two different VS with SNMP.
I already could set the SNMP into the VS-Mode and it seems working well.
For the Virtual Memory we use the following OIDs:
memActiveVirtual64 = .1.3.6.1.4.1.2620.1.6.7.4.2
memTotalVirtual64 = .1.3.6.1.4.1.2620.1.6.7.4.1
We try to get the following information from vsid1 (marked red😞
[Expert@vsx01:0]# vsenv 1
Context is set to Virtual Device vs1 (ID 1).
[Expert@vsx01:1]# fw ctl pstat
Virtual System Capacity Summary:
Physical memory used: 8% (1563 MB out of 17892 MB) - below watermark
Kernel memory used: 4% (726 MB out of 17892 MB) - below watermark
Virtual memory used: 3% (763 MB out of 23379 MB) - below watermark
Used: 186 MB by FW, 544 MB by zeco
Concurrent Connections: 27% (19457 out of 69900) - below watermark

.....
But what we get are the following values from these counters:
[Expert@vsx01:1]# cpstat -f memory os
Total Virtual Memory (Bytes): 52948054016
Active Virtual Memory (Bytes): 3940368384
Total Real Memory (Bytes): 25015111680
Active Real Memory (Bytes): 3940106240
Free Real Memory (Bytes): 21075005440
Memory Swaps/Sec: -
Memory To Disk Transfers/Sec: -
Does someone know how we can monitor the "real" virtual memory of a VS-instance?
So why does both commands above show me so different informations when I'm in the "vsenv 1" ?
Thank you for your answer.
Best regards,
Peter
