Hi,
I have noticed that my Windows 2000 Servers doesn´t disply the Physical Memory
values. As far as I know is a problem with the Client OS that have no support
for this OIDs.
I'm trying to develop my own interface, I'm already able to discover and poll
the Physical memory but Im not able to view any graph.
First of all I have to install SNMP4W2K in your Windows 2000 Machines to get
the OIDs to the physical memory values, search the web and you will find it.
My discovery function (working fine):
<?
function discovery_memoryW2K ($ip,$rocommunity,$hostid,$param) {
$memory = array();
$description = "Real Memory (W2K)";
$size = snmp_get ($ip, $rocommunity,
".1.3.6.1.2.1.25.2.2.0");
$mem_total = snmp_get ($ip, $rocommunity,
".1.3.6.1.2.1.25.2.2.0");
$mem_used = snmp_get ($ip, $rocommunity,
".1.3.6.1.4.1.311.1.1.3.1.1.1.29.0");
list($size,$aux)= explode(" ", $size);
$mem_free = $mem_total - $mem_used;
$memory[1]["interface"] = "Physical Memory";
$memory[1]["mem_size"] = $size;
$memory[1]["mem_total"] = $mem_total;
$memory[1]["mem_used"] = $mem_used;
$memory[1]["mem_free"] = $mem_free;
if ($size > 0) {
$memory[1]["admin"] = "up";
$memory[1]["oper"] = "up";
} else {
$memory[1]["admin"] = "down";
$memory[1]["oper"] = "down";
}
$memory[1]["description"] = "Physical Memory on Windows 2000
computers";
return $memory;
}
?>
I have configured a new interface with the following options:
AD Enabled: True
Validate in AD: True
Discovery Function: memoryW2K
Discovery Parameters: none
Discovery Default Poller: Memory W2K
Have Graph: True
Default Graph: Memory Usage W2K

My Graph Function:
<?
function graph_memw2k_util ($data) {
$opts_DEF = rrdtool_get_def($data,array(
mem_total_b=>"mem_total",
mem_used_b=>"mem_used"));
$opts_GRAPH = array(
"CDEF:mem_total=mem_total_b",
"CDEF:mem_used=mem_used_b",
"CDEF:mem_free=mem_total,mem_used,-",
"CDEF:mem_free_p=mem_free,100,*,mem_total,/",
"CDEF:mem_used_p=mem_used,100,*,mem_total,/",
"LINE3:mem_total#FF0000:'Total Memory\: '",
"GPRINT:mem_total:MAX:'%6.0lf %sB\\n'",
"AREA:mem_used#FF8800:'Used Memory '",
"GPRINT:mem_used:MAX:'Max\: %6.2lf %sB'",
"GPRINT:mem_used_p:MAX:'(%2.0lf %%)'",
"GPRINT:mem_used:AVERAGE:'Average\: %6.2.lf %sB'",
"GPRINT:mem_used_p:AVERAGE:'(%2.0lf %%)'",
"GPRINT:mem_used:LAST:'Last\: %6.2lf %sB'",
"GPRINT:mem_used_p:LAST:'(%2.0lf %%)\\n'",
"STACK:mem_free#00CC00:'Free Memory '",
"GPRINT:mem_free:MAX:'Max\: %6.2lf %sB'",
"GPRINT:mem_free_p:MAX:'(%2.0lf %%)'",
"GPRINT:mem_free:AVERAGE:'Average\: %6.2lf %sB'",
"GPRINT:mem_free_p:AVERAGE:'(%2.0lf %%)'",
"GPRINT:mem_free:LAST:'Last\: %6.2lf %sB'",
"GPRINT:mem_free_p:LAST:'(%2.0lf %%)\\n'",
);
$opts_header[] = "--vertical-label='Used Memory'";
return array ($opts_header, @array_merge($opts_DEF,$opts_GRAPH));
}
?>
I always receive the same message when I open the Performance graph of the
Memory interface: " The RRDTool files for Interface ID 2309 (from Host ID 4),
has not been created by the Poller Process yet" I goes to host and the target
Server its being polled every 5 minutes correctly.
I dont know if the problem is with the poller or with the graph function, is
there any way to debug that?
Im using jffnms 0.8.3 over Debian 3.1. (RRDTool version 1.0.49)
I hope this helps and somebody could help me solving this issue.
Thanks in advance,
Felipe
