Hi all,
I've heard from a Nagios(?)-feature that I would like to see in (a future) Hobbit release very much, alerting based on dependies. Let me explain why:
Suppose two red conditions:
1-a disk failure (hardware error) -> support rep A is warned
2-an application failure on that particular disk -> support rep B is warned
but...
It's no use alerting support rep B while that disk is still unavailable. You would like to be warned after the disk has recovered or replaced. Than error 1 will be green again, but it is possible that test 2 still has errors. So I would like to set up a sort of dependancy between test 2 and 1. Alert me for the application, but the disk must be useable (status green).
Will this be possible some day?

man bb-hosts [...] depends=(testA:host1/test1,host2/test2),(testB:host3/test3),[...] This tag allows you to define dependencies betweeen tests. If "testA" for the current host depends on "test1" for host "host1" and test "test2" for "host2", this can be defined with depends=(testA:host1/test1,host2/test2)
When deciding the color to report for testA, if eitherhost1/test1 failed or host2/test2 failed, if testA has failed also then the color of testA will be "clear" instead of red or yellow.
Since all tests are actually run before the dependencies areevaluated, you can use any host/test in the dependency - regard-less of the actual sequence that the hosts are listed, or the tests run. It is also valid to use tests from the same host that the dependency is for. E.g.
1.2.3.4 foo # http://foo/ webmin depends=(webmin:foo/http)is valid; if both the http and the webmin tests fail, then webmin will be reported as clear.
Note: The "depends" tag is evaluated on the BBNET server whilerunning the network tests. It can therefore only refer to other network tests that are handled by the same BBNET server - there is currently no way to use the e.g. the status of locally run tests (disk, cpu, msgs) or network tests from other BBNET servers in a dependency definition. Such dependencies are silently ignored.

Many thanks! Sorry I had not read the man pages completely.
