[Xymon] Depends tag working configuration

[Scot Kreienkamp]

Mario,

If I’m understanding your email correctly, you changed the IP on 6030 to a non-pingable address, correct?  If so, then you are performing your test incorrectly.  The tag you posted means that 6030 depends on 5030, but to test it you changed the IP on 6030 only.  To test it with the tag you posted, 5030 and 6030 must BOTH be non-pingable.  In that scenario the conn test on 6030 should change to clear.

Also, if you only want a connectivity test then you may be looking at the wrong tag.  Look up the route tag that goes in hosts.cfg and see if that will give you what you want.

Hi Scot,
Thanks for your help.
I´ve used your example and the dependency worked using the http test.
So then, I´ve changed the depends tag configuration to use the conn test and this didn't work.
First test (worked as expected!):
- Stopping apache on "6030" the result was a clear status on 6030/http as 5030/http was up.

0.0.0.0  6030 # http://paq depends=(http:5030/http) noconn
0.0.0.0  5030 # http://fara  noconn

Second test (connectivity configuration on depends): This test didn´t work.
- I´ve changed the IP from 6030 to a non pingable IP and let an available/online IP on "5030" and the depends tag didn´t work.
10.0.0.139  6030 # http://paq depends=(conn:5030/conn) testip
10.0.0.137  5030 # http://fara  testip

Do you have a dependency configuration based on connectivity test working on your system?


Thanks & Regards,
Mario

Sure.  Here is a working config:


0.0.0.0    6030 # http:// 6030:8090/Main/ depends=(http:5030/http)
0.0.0.0  5030 # http://5030

So I’ve defined an HTTP test on 5030 and 6030, and set the HTTP test result on 6030 to depend on the HTTP test on 5030.  In my case, 5030 is the DB server and serves up a web page if the database is up.  If the database is down there’s no way the HTTP test will succeed on 6030, so I don’t really care if 6030 is alerting me in that case.

If you have any more trouble it would be helpful to see your configuration.  I saw you mention ICMP earlier… keep in mind that depends sets a test dependent on another test, so if you want ICMP you have to set it to depend on the conn test.  You can’t use ICMP in the depends.  It has to be a column name.

Hi,
Thanks, Scot.
Yes, that´s what I´m doing here.
The test configuration was done with only core network tests and that are directly running on the core server and it´s not working.
Do you have this configuration working on your server? Could you share it?
Thanks & Regards,
Mario

The depends tag works, but only for tests done by the core network tester itself.  It will not work on any external tests.

Hi All,
I´m trying to make the "depends=" hosts.cfg tag to work on Xymon version 4.3.24.
Reading some old threads here, it became not clear to me if this configuration tag currently works or not.
Has someone here have the depends tag working?
I know I can use the route tag, but my intention it´s to use another network protocol and not ICMP for the dependency.


Thanks & Regards,
Mario
