10 Jan 2019, Konstantin Olchanski, Info, removal of cm_watchdog()
|
cm_watchdog() has been removed from the latest midas sources. The watchdog functions performed by cm_watchdog() were

timed-out clients.

I added json-rpc requests for ODB /Script and /CustomScript (the first one shows up on the status page in the left hand side menu, the
second one is "hidden", intended for use by custom pages).
