Attempt to make hot services dependencies

[claneys]

I try to introduce dependencies into configuration packs. The idea is to have a service dependencies config file into each pack that will be read by a hot-dependencies script then processed by hot-dependencies module.

The script just make association and wrote a json file. To do so, it will communicate with the arbiter asking it a hosts list with their use flags to know which service dependencies read and apply for each of them.

The difficulty now is to retrieve list of parents hosts of hosts since we can have services relies on services on others hosts.

act_depend_of and act_depend_of_me aren't available at runtime to read them, so I try to figure it out how to retrieve this list or any other way to do so.

No available? strange. Look at parent_dependencies and child_dependencies properties, should be easier to parse :)

But why running properties should not be available? They are more valuable to query than properties one :)

[claneys]

running_properties are availables indeed... But if it try to retrieve child_dependencies ou act_depend_of, I get : Connexion error to http://localhost:7770/ : The requested URL returned error: 500 Internal Server Error

[claneys]

I managed how to get out of that error. Just pickle the returned data.

Now i wonder what would be the best way to read a nagios config file and handle it.

[naparuba]

read a nagios config file and all what is inside? The shinken.object.Config() object is done for this :)

[claneys]

Yup, I stucked due to the use of log object that need to load an object to create its broks and load the message. (If i understand correctly :)

[claneys]

Thanks naparuba

[claneys]

Plugins works. Cool !

It's working as follow, parse all config files based on shinken.cfg and kept only servicedependcy part. Then map all servicedependency, which have template name for host_name and dependent_host_name directive, wtih host that have those template.

It is beta version for now, I have some problem to connect to the arbiter at launch (how to connect to when arbiter isn't ready :d ? ) And it's seems that arbiter doesn't launch mapping_command at mapping_command_interval but just at launch. Weird. Someone has an idea why ?

[naparuba]

nop, when the arbiter run it launc hte 'tick' method of the module once a second, and it's up to the module to ook at it and relaunch it if need. Look at debug logs, should be something about it

Thanks, it's ok now. I has problem when running arbiter launched manually with --debug parameter but specifying log_level=DEBUG in shinken.cfg resolv all my problems and everything works normally.

I'll put that in core if it's ok.

[naparuba]

--debug and log_level will get a little differences indeed. I should fix it, because with just log_level, print calls are not "catched" and it's a problem for huge debugging :(

Okay. I'll delay push in core because lack of test...

[Seb-Solon]

Well i use this print issue as an advantage. Run not as a daemon but with a higher log level. This way I can easily see my print in the shell :)

[claneys]

Is it normal that multiple host_name definition or service_description in a servicedependency doesn't split value into list ? Is the final component to support splitting multiple definition or the primary object ?

[Seb-Solon]

Any news on that ? Maybe related to https://github.com/naparuba/shinken/issues/1029

I'll close it this week end to freeze if no news.
