Alert "java system not available" in technical monitoring

Hi,

I'm getting the alert "java system not available" in the technical monitoring of Solution Manager 7.3 SP8 regarding a netweaver 7.3 java system.

The following error comes up:

[RC=404] URL http://<hostname>:50000/index.html called unsuccessfully

I think this URL is for a Netweaver 7.0 system. I changed the metric as in the following screenshot, but the error still appears. I already changed parameter to "/startPage", but it still tries to ping index.html.

Any ideas?

Regards
