Thanks all. So I guess for now I have to live with systemready support
only. 

For background, I am using the SystemReady marker service to determine
when an application has started and compute some metrics.

I am 'weakly binding' to system ready by just a servicetracker for the
SystemReady interface, without actually importing the classes. The
reason is that I want my bundle to start ASAP and start tracking
events.

Tyring something more specific for healtchecks would be hard without
actually binding to the code, so I'll pass on that.

Thanks,
Robert

Hi,

so currently this is not yet possible, but it should be easy enough to 
get there.
I created the issue [1] for this. Thanks Raymond for the link to the 
Condition
Service Draft RFC, I have to read this in detail first but I think that 
should not
be too hard to implement it in this direction to be prepared once this 
is final.


Best Regards

Hi Robert.

Apologies for the long delay.

I had a look as well as the Felix HCs and AFAICT there is no such 
"marker"
service registered that you can listen for. The original design for 
HCs was

not for readiness, but for more generic checks.
You might be stuck with a listener of sorts on all checks using this 
tag:


https://github.com/apache/felix-dev/blob/master/healthcheck/generalchecks/src/main/java/org/apache/felix/hc/generalchecks/FrameworkStartCheck.java#L46
Maybe Georg can help with more clear instructions.

We should also add a systemready tag to the Felix HCs.

Personally, I think we need to have systemready implemented with HCs 
but

keep the current API or merge the two properly.

Sorry I couldn't be more helpful.

Hi


BTW, the page at [3] points to a missing README file.

This was due to the move to github and is now fixed.

Hi Robert.

Apologies for the long delay.

I had a look as well as the Felix HCs and AFAICT there is no such "marker"
service registered that you can listen for. The original design for HCs was
not for readiness, but for more generic checks.
You might be stuck with a listener of sorts on all checks using this tag:
https://github.com/apache/felix-dev/blob/master/healthcheck/generalchecks/src/main/java/org/apache/felix/hc/generalchecks/FrameworkStartCheck.java#L46
Maybe Georg can help with more clear instructions.

We should also add a systemready tag to the Felix HCs.

Personally, I think we need to have systemready implemented with HCs but
keep the current API or merge the two properly.
