Using iSCSI Enterprise 1.69, I can access the iscsiip/check_sys stats properly (although the index.html page isn't setup correctly) by manually going to /check_sys/127.0.0.1-load.html, etc. However, the data is no longer updating! It looks like it only updated for the first 8 hours or so the machine was up, and then stopped updating the graphs. Any reason why this might happen? And how to get it up and going again?
Could be the memory on the DOM is full; try re-flashing again with 1.69 ISO image or remove logs then try again. I tested with 1.72 and received recent status updates within a few min. when entering in the check_sys/127.0.0.1.html.
When re-flashing please save your settings in Maintenance > Miscellaneous, also please read the release notes (Open-E_iSCSI_Enterprise_Release_Notes_v_1.72.pdf) for any updates from 1.69 to 1.72 (last update for iSCSI Enterprise) that is available on our website located in Software updates section or our FTP site.
