Header file for the DNS Extensible Object data definitions
|

|
|
|

|
|
This file contains definitions to construct the dynamic data
|

|
|
which is returned by the Configuration Registry. Data from
|
||
|
|
various system API calls is placed into the structures shown
|
||

Adding a Counter to the Extensible Objects (DNS) Code
|
||
|
|
|
||
|
|
Note that the order or position of counters is significant.
|
||
|
|
There are two orders which are important, the order of counters indexes for
|
||
|
|
names and help, and the order of data in the shared data block for passing
|
||
|
|
your values.
|
||
|
|
You want to maintain consistent counter order, and consistent data layout,
|
||
|
|
across all five files to be modified.
|
||
|
|
|
||
|
|
You want to make sure that your binary matches the .h/.ini file on the target,
|
||
|
|
which gets loaded into the registry.
|
||
|
|
|
||
|
|
1. nt\ds\dns\server\perfdns\dnsperf.h
|
||
|
|
This file is copied to the %windir%\system32 directory of the target along
|
||
|
|
with the dnsctrs.ini file.
|
||
|
|
a. Add your counter offset at the end of the counter name list. Order
|
||
|
|
significant.
|
||
|
|
b. Add an extern reference for the pointer which the actual code will use
|
||
|
|
to set the measured value. Order doesn't matter.
|
||
|
|
c. Change the DNS peformance counter version number so the counters will
|
||
|
|
be reloaded on the next reboot.
|
||
|
|
|
||
|
|
2. nt\ds\dns\server\perfdns\dnsctrs.ini
|
||
|
|
This file is also copied to the %windir%\system32 directory of the target and
|
||
|
|
is read by the lodctr/unlodctr program to copy the counters in the registry.
|
||
|
|
a. Supply your counter visible name and help. These are used by the perfmon
|
||
|
|
program. Order doesn't matter.
|
||
|
|
|
||
|
|
3. nt\ds\dns\server\perfdns\datadns.h (this file)
|
||
|
|
a. Add your data offset definition. Order significant.
|
||
|
|
b. Add a field to the DSA_DATA_DEFINITION for your counter. Order significant.
|
||
|
|
|
||
|
|
4. nt\ds\dns\server\perfdns\perfdns.c
|
||
|
|
This is the dll which perfmon uses to learn about your counters, and to read
|
||
|
|
them out of the shared data area.
|
||
|
|
a. Runtime Initialize the DnsDataDefinition name index and help index
|
||
|
|
(CounterNameTitleIndex & CounterHelpTitleIndex). Order doesn't matter.
|
||
|
|
b. Update the huge initializer for the DnsDataDefinition array of counters to
|
||
|
|
include your new counter (defined in 3b). Order important.
|
||
|
|
|
||
|
|
5. nt\ds\dns\server\server\startperf.c
|
||
|
|
This file provides init function, startPerf(), which is called when DNS server
|
||
|
|
starts. It loads the shared memory block and initializes pointers to the
|
||
|
|
counter fields. It also loads/reloads the registry counters as necessary
|
||
|
|
according the version field.
|
||
|
|
a. Declare the pointer to the data in your counter. Order does not matter.
|
||
|
|
b. Initialize the pointer to the right location in the shared data block.
|
||
|
|
Order of assignments doesn't matter.
|
||
|
|
c. Update the max size assert if your new counter is the last one
|
||
|
|
d. Initialize your pointer to the dummy value on error
|
||
|
|
|
||
|
|
6. yourfile.c
|
||
|
|
This is the file in the dns where the measured counter is changed. Use public
|
||
|
|
operations, INC/DEC/ADD/SUB/SET, in dnsperf.h on the pointer to your data.
|
||
|
|
|
||
|
|
Note: adding an object is a little more work, but in all the same
|
||
|
|
places. See the existing code for examples. In addition, you must
|
||
|
|
increase the *NumObjectTypes parameter to CollectDnsPerformanceData
|
||
|
|
on return from that routine.
|
||
