Measures reported by CtxCheckDnsTest
This test performs a forward DNS lookup using the local host name to query the local DNS server in the computer's environment for the computer's IP address, and reports whether the lookup was successful or not. The test can also be optionally configured to perform a reverse DNS lookup and reports its success/failure.
The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement

| Forward_lookup |
Indicates whether the forward lookup of the IP address from the local DNS is successful or not. |
|
This measure reports a value Success if the IP address lookup is successful and reports a value Failure if the lookup is not successful. The value Failure may also indicate that the returned IP address does not match with that of the IP address that is registered locally.
The numeric values that correspond to the above-mentioned states are as follows:
| State |
Numeric Value |
| Success |
0 |
| Failure |
1 |
Note:
By default, this measure reports the above-mentioned states while indicating whether the forward lookup of the IP address is successful or not. However, the graph of this measure will be represented using the numeric equivalents i.e., 0 and 1 only.
|
| Reverse_lookup |
Indicates whether the reverse lookup of the IP address is successful or not. |
|
This measure reports a value Success if the reverse lookup of the IP address is successful and reports a value Failure if the reverse lookup is not successful.
The numeric values that correspond to the above-mentioned states are as follows:
| State |
Numeric Value |
| Success |
