We’re seeing garbage data on some of our AIX (7.1) clients like this:
red Thu Jun 23 15:29:28 EDT 2011 - Memory CRITICAL Memory Used Total Percentage &red Physical 18446744073709551177M 4096M18446744073709551606% &green Swap 40M 4096M 0%
The ones that exhibit problems have Active Memory Expansion enabled. Is there anything we can do to get valid data? Should I report it as a bug?

Hi,
As far as I recall, Henrik fixed this in the newer versions - 4.3-branch - something with a sanity-check in the code, so that we shouldnt get these bogus alerts. Problem is (as I remember) that its actually the system that sends these values back to the agent - so it's not related to Xymon.

Can you post the output of vmstat 1 2

I looked at that a bit, but I have no idea what normal is, so it didn’t tell me much. I certainly didn’t see anything like “18446744073709551177M”. :)
The problem seems to have cleared on its own for now. If it reappears, I’ll send the output from that command. Thanks.

OK, here's one. The report looks like this:

The vmstat section looks like this:
[vmstat] System configuration: lcpu=16 mem=28672MB ent=0.50
What does the "[realmem]" section look like ? If you look in the xymonclient-aix.sh script, you'll see that it uses these commands:
echo "[realmem]" lsattr -El sys0 -a realmem echo "[freemem]" vmstat 1 2 | tail -1 echo "[swap]" lsps -s
All of this is in the "client data" linked to from the detailed status page. It would be nice to have an example both when it is green and when it is red.
Regards, Henrik
