<p class="MsoNormal">A change to how our DNS is configured has caused the DNS test on xymonnet to reach around 50 seconds. Combined with the other tests, the total time exceeds the time limit (60). Because of this, xymonnet has been alarming for a very long

Hi Foster,<br>
<br>
The warning time passed in by xymonnet can be adjusted with the --timelimit= option given in the CMD above. By default, it's equivalent to the INTERVAL runtime (assuming xymonnet is run with one, which it usually is), since it's there to let you know that the
testing interval isn't being met. You can also adjust that upwards to match the average time things are taking.<br>
<br>
Unfortunately, DNS lookups-as-tests are handled differently from the other tests, and timeouts or network problems can increase xymonnet's runtime linearly with failures. Assuming the ones you're testing are the only ones you need to test (i.e., remove dead
hosts), reducing '--dns-timeout' as low as you're comfortable with is the only other real tweak here. Enabling/disabling the test changes whether xymon considers an outage to be an alertable issue, but doesn't prevent xymonnet from checking (and waiting on)
that service in the first place.<br>
<br>
If you have a large number of these with different SLAs, or a huge number of DNS servers to test, there are advanced ways of setting up xymonnet runtimes to isolate these effects. Basically, you'd set up a separate instance of xymonnet just for doing DNS tests,
while excluding them from your normal install.<br>
<br>
