Infinispan cache health check from HotRod client

[purushos]

Hi,

We use Infinispan v8.2.6 in our application. We access the cache using HotRod client library. We are adding some health checks in our application to monitor cache accessibility using HotRod. Do we have any health API's in the HotRod client library (or) do we have to perform a cache get / put operation to check health?

We saw that RemoteCacheManager has a isStarted() method. Can this be used to determine health?

RemoteCache.ping() might help?

[galder.zamarreno]

Actually, ping is not exposed in interface, but the implementation RemoteCacheImpl has it.

Infinispan server has special endpoints for monitoring cluster health. The API is exposed via:

- Programmatically (using embeddedCacheManager.getHealth())

- JMX

- CLI

- REST (using WildFly HTTP Management API)

Thanks!

If the RemoteCache is pingable, can we assume that it is available for both read and write operations?

Yes. More detailed information on health checks can be found here.
