Chapter 4: Configuring the High-Level Network
To configure a wmi monitor for the server node
Using the Configuration utility or the bigpipe command, create a health
check monitor using the wmi monitor template. The wmi monitor template
is shown in Figure 4.3.
monitor type wmi {
interval 5
timeout 16
dest *:12346
username ""
password ""
method "POST"
urlpath "/scripts/F5Isapi.dll"
cmd "GetCPUInfo, GetDiskInfo, GetOSInfo"
metrics "LoadPercentage, DiskUsage, PhysicalMemoryUsage:1.5,
VirtualMemoryUsage:2.0"
post "<input type=’hidden’ name=’RespFormat’ value=’HTML’>"
agent "Mozilla/4.0 (compatible: MSIE 5.0; Windows NT)
}
Figure 4.3 wmi monitor template
The monitor template contains default values for all the attributes. These are
template defaults. In creating a custom monitor from the template, the only
default values you are required to change are the null values for username
and password. For example:
b monitor my_wmi ’{ use wmi username "dave" password "$getm" }’
You may also add commands and metrics and modify metric attribute
values. The complete set of commands, associated metrics, and metric
attribute default values are shown in Table 4.4.
