Hi all,
An issue has arisen over the Christmas period that is causing me some confusion. I have a Sun server running sparc Solaris 10 which has the 4.2.0 Hobbit client installed on it, this client sends its data to my 4.2.2 Xymon server. The client machine has 64GB of memory and 16GB of swap space.
The issue I have at the moment is that Xymon's web pages show the server as having 64GB (or so) of swap and the swap is 91% full, yet a swift look on the server itself shows it to have on 16GB of swap and none of which is in use.
I have also confirmed that the machine this data is coming from is the same as the one I think it is and that I am not logging on to a different server!
The relevant portions of the client data are as follows:
[df] Filesystem kbytes used avail capacity Mounted on /dev/odm 0 0 0 0% /dev/odm swap 5123480 1328 5122152 1% /etc/svc/volatile swap 5122440 304 5122136 1% /tmp swap 5122136 0 5122136 0% /dev/vx/dmp swap 5122136 0 5122136 0% /dev/vx/rdmp /dev/md/dsk/d0 16525754 8227674 8132823 51% / /dev/md/dsk/d30 16525754 5177145 11183352 32% /var /dev/md/dsk/d40 1025903 654865 309484 68% /home ... [top] load averages: 2.26, 2.30, 1.84; up 33+21:36:10 12:20:22 158 processes: 156 sleeping, 2 on cpu
Memory: 64G phys mem, 15G free mem, 16G swap, 16G free swap ... [vmstat] kthr memory page disk faults cpu r b w swap free re mf pi po fr de sr m0 m1 m2 m1 in sy cs us sy id 0 0 0 23250064 29333720 407 464 877 1891 1885 0 0 13 8 8 0 1862 9947 5678 5 1 93 0 0 0 5123960 15420256 642 583 460 6928 6905 0 0 19 12 12 0 5384 34448 17397 15 4 81 ...
So as you can see from the [top] section above the server has only 16GB of swap configured, yet the memory web page for this server has:
Tue Jan 6 12:40:20 GMT 2009 - Memory CRITICAL
Memory Used Total Percentagegreen Physical 49541M 65536M 75% red Swap 57495M 62474M 92%
I guess I am having a problem understanding how Xymon interprets memory. I am fairly sure I have looked at this in the past but I still don't understand it 8-(
